The snake, even if judged to be dead, should be handled very carefully, since decapitated heads can bite for up to one hour! They may manifest within patient assessment hours of bite without any clinical features suggestive of encephalopathy. Evaluation should begin with the assessment of the airway, breathing and circulatory status. Antivenoms may be species specifc (monovalent) or efective (Table 3) against several species (polyvalent) (Table 4). During the initial evaluation, several locations on the bitten extremity The correct use of antivenom is the most important component of (at the bite site and at least two sites more proximal) should be marked hospital care and not every bite, even with a poisonous snake, merits and the circumferences should be measured every 15 minutes until its use.

After lodging these guidelines into their minds and hearts, knowledgeable and skillful nurses and nursing students need healthy and supportive work environments to help bring these guidelines to life. Together, we can ensure that Ontarians receive the best possible care every time they come in contact with us. Guidelines should not be applied in a “cookbook” fashion but used as a tool to assist in decision-making for individualized client care, as well as ensuring that appropriate structures and supports are in place to provide the best possible care. Systematically develop a plan to implement the recommendations using associated tools and resources. These guidelines are not binding for nurses and their use 7 should be flexible to accommodate client/family wishes and local circumstances. Dementia and Depression If client is incapable, nurses should approach substitute decision makers regarding care issues. If there is no Power of Attorney, nurses should encourage and facilitate the process for older adults to appoint Power of Attorney and to have discussions about end of life treatment and wishes while mentally capable. Involvement of all members (whether in a direct or indirect supportive function) who will contribute to the implementation process. Opportunities for reflection on personal and organizational 14 experience in implementing guidelines. Elder friendly programs and services should be developed reflecting their unique needs including the family and caregivers. Every older person (65 years and over) has a right to timely, accurate, and thorough comprehensive geriatric assessments and related caregiving strategies as indicated. Changes in mental status should guide the selection, administration and appropriate interpretation of assessment tools. Delirium, dementia and depression are not synonymous with aging, but prevalence increases with chronological age. Caregiving strategies for delirium, dementia and depression should honour the older person’s uniqueness, preferences, values and beliefs, and involve the individual in decision-making. Caregiving strategies are most comprehensive when conducted from an interdisciplinary approach and when family/significant others are welcomed as partners in the process. The assessment and development of caregiving strategies must be an individualized and dynamic process that responds to the changing needs of the older person. Pivotal to all care strategies is the knowledge that all behaviour is meaningful and requires skilled evaluation of the physiological, emotional, psychological, social and environmental antecedents that are contributing factors. The panel consensus was that all three topic areas should be kept together because of the overlap in symptomatology. Caregiving Strategies for Older Adults with Delirium, Dementia and Depression An effort has been initiated in this section to weave information and multi-component care strategies together specific to delirium, dementia and depression in older adults. The nurses’ role is to assess 18 for all three conditions within the context of the following tenets of care: Know the person Relate effectively Recognize retained abilities Manipulate the environment Excellence in care requires using best practice assessment (including screening and ongoing assessments over time), using standardized instruments, and measuring the outcomes of care. Kaleidoscope of Care Strategies for Delirium, Dementia and Depression Evidence of Depression Details of caregiving strategies for delirium, dementia and depression can be found in chapters 1 to 4. The guideline focuses on: (1) Practice recommendations: directed at the nurse to guide practice regarding caregiving strategies for older adults with delirium, dementia and/or depression; (2) Educational recommendations: directed at the educational institutions and organizations in which nurses work to support its implementation; (3) Organization and Policy recommendations: directed at the practice settings and the environment to facilitate nurses’ practice; (4) Evaluation and monitoring indicators. It is acknowledged that effective healthcare depends on a coordinated interdisciplinary approach incorporating ongoing communication between health professionals and clients, ever mindful of the personal preferences and unique needs of each individual client. At the onset, the panel discussed and came to a consensus on the scope of the best practice guideline. The panel identified a total of 21 clinical practice guidelines related to geriatric mental health assessment and management. These guidelines were reviewed according to a set of initial inclusion criteria, which resulted in elimination of nine guidelines. Guideline was strictly about the topic areas (delirium, dementia, and depression). Caregiving Strategies for Older Adults with Delirium, Dementia and Depression the resulting 12 guidelines were critically appraised with the intent of identifying existing guidelines that were current, developed with rigour, evidence-based and which addressed the scope identified by the panel for the best practice guideline. Intervention in the management of behavioural and psychological aspects of dementia. Stakeholders represented various healthcare disciplines as well as professional associations. Discussion and consensus resulted in revisions to the draft document prior to publication and evaluation.

When a novice learns a novel movement focusing on technique (internal focus) could help their learning  treatment esophageal cancer order accupril 10mg otc. For a skilled person medications on carry on luggage cheap 10 mg accupril with amex, performance improves if training focuses on tasks outside the body (external-focus) but it reduces when the focus is on internal processes within the body [78 medicine website discount accupril 10mg with amex, 79] medications 8 rights cheap 10 mg accupril overnight delivery. For example medicine cabinets recessed buy generic accupril on-line, there is greater accuracy in tennis serves and football shots when the subjects use external-focus rather than internal-focus strategies [80, 81]. This principle strongly suggests that internal focus on TrA or any other muscle group will reduce skilled athletic performance. Lets imagine two scenarios where we are teaching a patient to lift a weight from the floor using a squat position. In the first scenario, we can give simple internal focus advice such bend your knees, and bring the weight close to your body, etc [83, 84]. It would be next to impossible for a person to learn simple tasks using such complicated internal focus approach. It is well established that when a novice learns a new motor skill they tend to use a co-contraction strategy until they learn to refine their movement . Co contraction is known to be an “energy waster” in initial motor learning situations. To introduce it to skilled movement will have a similar “wasteful” effect on the economy of movement. Minetti states: “to improve locomotion (and motion), mechanical work should be limited to just the indispensable type and the muscle efficiency be kept close to its maximum. However, these claims are not supported by clinical studies: Abdominal / stability exercise as prevention of back pain In one study, asymptomatic subjects (n=402) were given back education or back education + abdominal strengthening exercise . They were monitored for lower back pain for one year and number of back pain episode were recorded. This study was carried out on asymptomatic subjects who were identified as having weak abdominal muscles. Indeed it is now recommended that patients should be encouraged to maintain their own preferred exercise regime or given exercise that they are more likely to enjoy. But the patient should be informed that it is only as effective as any other exercise. More importantly, in the last decade our understanding of the etiology of back pain has dramatically changed. Psychological and psychosocial factors have become important risk and prognostic factors for the onset of acute back pain and the transition of acute to chronic pain states . Genetic factors  and behavioural / “use of body” are also known to be contributing factors. Localised, minor asymmetries of the spine, which would include stability issues, have been reduced in their importance as contributing factors to back pain. It is difficult to imagine how improving biomechanical factor such as spinal stabilisation can play a role in reducing back pain when there are such evident psychological factors associated with this condition. This can be clarified by grouping potential causes for back injury into two broad categories: 1 Behavioural group: individuals who use their back in ways that exert excessive loads on their spine, such as bending to lift  or repetitive sports activities [106-108]. In the behavioural group, bending and lifting is associated with a low level increase in abdominal muscle activity, which contributes to further spinal compression . Any further tensing of the abdominal muscle may lead to additional spinal compression. Since the spinal compression in lifting approach the margins of safety of the spine, these seemingly small differences are not irrelevant . Sitting, however, is associated with increased activity of abdominal muscle (when compared to standing)  as well as increased stress on the lumbar discs (compared to standing) . Increasing the co-contraction activity of the anterior and back muscles is unlikely to offer any further protection in the patients with disc narrowing / pathology, and may even result in greater spinal compression. It is unknown whether core tensing can impede the movement of the unstable segments. This seems unlikely because even in healthy individual creep deformation of spinal structures will eventually take place during sitting . The creep response is likely to be increased by further co-contraction of trunk muscles. Most injuries occur within a fraction of a second, before the nervous system manages to organise itself to protect the back. Often injuries are associated with factors such as fatigue  and over training . These factors when combined with sudden, unexpected high velocity movement are often the cause of injury . It is difficult to see the benefit of strong TrA, abs or maintaining a constant contraction in these muscles in injury prevention. Continuous and abnormal patterns of use of the trunk muscles could also be a source of potential damage for spinal or pelvic pain conditions. Another recent study examined the effects of abdominal stabilization maneuvers on the control of spine motion and stability against sudden trunk perturbations . The abdominal stabilization maneuvers were abdominal hollowing, abdominal bracing and a “natural” strategy. Abdominal bracing did improve stability but came at a cost of increasing spinal compression. The natural strategy group seems to employ the best strategy – ideal stability without excessive spinal compression. An increase in intra-abdominal pressure could be a further complication of tensing the trunk muscles . It has been estimated that in patients with pelvic girdle pain, increased intra-abdominal pressure could exert potentially damaging forces on various pelvic ligaments . This study for example recommends teaching the patients to reduce their intra-abdominal pressure, i. Maybe our patients should be encouraged to relax their trunk muscle rather than hold them rigid In a study of the effects of psychological stress during lifting it was found that mental processing / stress had a large impact on the spine. It resulted in a dramatic increase in spinal compression associated with increases in trunk muscle co-contraction and less controlled movements . It offers a simplistic solution to a condition that may have complex biopsychosocial factors. The issues that underline the patient’s condition may be neglected, with the patient remaining uninformed about the real causes of their condition. Conclusion Weak trunk muscles, weak abdominals and imbalances between trunk muscles groups are not pathological, just a normal variation. Tensing the trunk muscles is unlikely to provide any protection against back pain or reduce the recurrence of back pain. Core stability exercises are no more effective than, and will not prevent injury more than, any other forms of exercise. Core stability exercises are no better than other forms of exercise in reducing chronic lower back pain. There may be potential danger of damaging the spine with continuous tensing of the trunk muscles during daily and sports activities. Patients who have been trained to use complex abdominal hollowing and bracing maneuvers should be discouraged from using them. It is surprising that the researchers and proponents of this method ignored such important issues.

The tilt is normally changed so that a retentive clasp will the surveying procedure is always started with the be positioned no farther occlusally or incisally than the cast firmly attached to the surveying table and the occlusal junction of the gingival and middle thirds of the tooth surfaces parallel to the platform of the surveyor. This produces a more esthetic result and may each abutment is examined for retentive undercuts. Certain structures within the oral cavity may interfere with If retentive undercuts are not present, they must be the insertion of a removable partial denture. In most instances, this may be tures may include teeth, bony prominences, soft tissue un accomplished by carefully recontouring enamel surfaces. In some instances, difficulties may In cases requiring more extensive changes, it may be nec be avoided by changing the tilt of the cast on the survey essary to place fixed restorations (eg, gold crowns or ing table. It should be a these restorations must be carefully planned and com goal of the practitioner to minimize surgical procedures, pleted prior to removable partial denture fabrication. Occlusal Middle Gingival Fig 7-12 Ideally, the terminus of the retentive clasp should be positioned no farther occlusally than the junction of the gingival and middle thirds of the tooth. Because the clasp arm must be ferences present distinctly different challenges to successful placed farther from the rotational center of the tooth, the removable partial denture therapy. Consequently, these corresponding lever arm is longer, and the resultant forces categories are discussed separately. Facial tipping also may cause the associated gingival Interferences in the maxillary arch. This contraindicates sources of interference in the maxillary arch is a palatal the use of a vertical projection clasp since the approach torus (Fig 7-13). A prominent palatal torus interferes with arm for this clasp must contact the mucosa. As a general approach arm for an infrabulge clasp stands away from the rule, changing the tilt of the cast on the surveying table will gingival tissues, it will act as a food trap and a potential not solve the problem. If this is not possible, surgical removal of the arch, a minor modification of the tilt may provide an the torus should be accomplished. If facially inclined Exostoses and undercuts are common on the buccal teeth are present on both sides of the arch, changing the surfaces of the maxillary arch (Fig 7-15). If in and undercuts prevent intimate contact between the re clination of the maxillary posterior teeth is not severe, the movable partial denture and the patient’s soft tissues. This practitioner may be able to move the height of contour to may result in an increased accumulation of food beneath a more appropriate level by recontouring enamel surfaces. Surgical correction of buccal exostoses and un may be forced to consider surveyed crowns to satisfy the dercuts is relatively simple and should be accomplished to requirements for clasp placement. Difficulty also may occur when the maxillary anterior In addition to the aforementioned factors, facial tipping ridge is edentulous and displays a noticeable undercut of posterior teeth may cause significant difficulties. Most of these undercuts can be controlled by maxillary posterior tooth tips facially, the height of contour giving the cast a posterior tilt (Fig 7-23). This makes anterior undercuts may be avoided by modifying or elimi positioning the buccal clasp arm more difficult for esthetic nating the anterior flange of the denture base and butting 210 Survey a b Fig 7-15 Exostoses and undercuts (arrows) commonly appear Fig 7-16 (a) Because a removable partial denture displays a linear on maxillary buccal surfaces and may complicate removable path of insertion (arrow), the area apical to an exostosis cannot be partial denture construction. If hard and soft tissue loss is minimal, this generous relief during framework construction. Therefore, surgery produce significant problems in removable partial denture must be considered for removable partial denture patients service. Such tori are difficult to avoid because of the exhibiting prominent lingual tori (Figs 7-25 and 7-26). If the delicate tissues Unlike maxillary posterior teeth, mandibular posterior overlying mandibular tori must be crossed, space must be teeth frequently display significant lingual tipping. This may provide a more esthetic result and eliminate the need for mechanical recontouring. Fig 7-21 If facially inclined teeth are present on both Fig 7-22 Noticeable undercuts are often encountered sides of the arch, changing the tilt of the cast will have in anterior edentulous areas. Maintenance of the hard and soft tis sues of the anterior ridge must be given high priority. Fig 7-23 Most anterior undercuts can be controlled by Fig 7-24 When sufficient ridge height is present, pros giving the cast a slight posterior tilt. In carefully selected situations, elimi nation of the denture base can yield excellent results. Therefore, these teeth may present substantial chal used in the overwhelming majority of these cases. These shorter 212 Survey Fig 7-25 Mandibular lingual tori are relatively common Fig 7-26 Surgical removal of mandibular lingual tori and can produce significant difficulties in removable provides an improved foundation for removable par partial denture therapy. Fig 7-27 Mandibular posterior teeth frequently display significant lingual tipping. As a result, these teeth may display no undercuts on their facial surfaces and large undercuts on their lingual surfaces. These areas may ex lar arch also may result in a major connector that stands hibit significant undercuts on one or both sides of the arch. This results in tongue interference and an un undercut, but has little effect when the arch displays bilat desirable space where food and debris may collect. Fortunately, acrylic resin denture bases are One solution is to use a labial bar major connector located adjacent to these undercuts and may be adjusted instead of a lingual bar or lingual plate. Therefore, surgical interven perience indicates that the labial bar has poor patient tion is rarely indicated to address the existence of such acceptance because of its bulk and location. Therefore, the use of a labial bar surfaces of mandibular canines and premolars (Fig 7-29). These prominences may produce soft tissue undercuts that the most common solution to this problem involves can interfere with the placement of denture bases and in recontouring the lingual surfaces of the remaining teeth or frabulge clasps. If these prominences and undercuts are placing restorations to eliminate the offending undercuts. If the condition is tered at the facial surfaces of mandibular canines and unilateral, a slight lateral tilt of the surveying table may premolars. When the condition is bilat undercuts that can interfere with the placement of eral, tilting the surveying table will have little effect. Esthetics When teeth are lost and are not replaced immediately, To obtain optimum esthetics in removable partial denture the resulting spaces may become smaller. In most therapy, (1) metal components must be concealed as effec instances, natural teeth will drift mesially to minimize these tively as possible, and (2) prosthetic teeth must be selected, spaces. Notable exceptions include the mandibular canines appropriately contoured, and properly positioned. By choosing the appropriate tilt, prosthetic teeth will have to display smaller mesiodistal the practitioner may disguise removable partial denture dimensions to fit into the reduced amount of space. The ideal position for a retentive clasp is in the gingival To address this dilemma, the practitioner should use a third of the clinical crown (Fig 7-30). When determining the final tilt of the cast, likelihood that the clasp will be visible, yet provides enough the space for one or more missing anterior teeth must be distance between the clasp and the marginal gingiva to given high priority. A more detailed de most always signal that the prosthesis will have a single scription of clasp selection is provided later in this chapter. This means that the surveyor must be the second requirement for obtaining optimum used to determine whether recontouring of the remaining esthetics involves the appropriate selection, contouring, natural teeth is indicated. Appropriate tooth only to produce an acceptable path of insertion, but also selection requires careful consideration of shade, size, and to ensure appropriate space for the prosthetic replace contour. If recontouring the proximal surfaces can Prosthetic teeth also must meet the functional produce the desired results, it is the procedure of choice. It is unrealistic to expect that If contouring the enamel surfaces is not possible, crowns prosthetic teeth supplied by a dental manufacturer will or other suitable restorations should be planned. Therefore, stock teeth Large undercuts on the proximal surfaces of anterior should be modified to reflect the esthetic and functional teeth also may create esthetic concerns (Fig 7-32). These spaces should be mini Guiding planes are parallel surfaces of abutment teeth that mized or eliminated by modifying the tilt (Fig 7-33) or re direct the insertion and removal of a partial denture. They contouring the proximal surfaces of the offending teeth are formed on the proximal or axial surfaces of the teeth (Fig 7-34). These undercuts can produce triangular spaces that detract from the appearance of the prosthesis and act as food traps. Fig 7-34 Undercuts also may be minimized or elimi nated by reshaping the proximal surfaces of teeth (arrows). The surveyor is restorations should be prepared, and wax patterns should used to locate surfaces that are parallel to the planned be shaped so their guiding surfaces are parallel to the es path of insertion or those that can be made parallel to this tablished tilt. Guiding planes are always paral lel to the path of insertion and are rarely greater than 2 to Determination of the most favorable tilt is an important 4mminheight. If the tilt of the cast is changed to mouth, the guiding planes are contacted by minor connec satisfy any of these factors, the effects of this change on tors or other rigid components of the partial denture. If a change ad result, guiding planes help stabilize the prosthesis against versely affects any of the remaining factors, a suitable com lateral forces. Of the four factors considered in determining the Path of insertion most favorable tilt of a cast, the development of guiding planes is the one that can be most easily compromised. The tilt of a cast determines the direction that the partial Guiding planes can be prepared on most enamel surfaces. If proposed abutments are to receive cast restorations, the the resultant pathway is termed the path of insertion. This path is determined during survey and design procedures and is parallel to the vertical arm of the surveyor. If guiding planes have been prepared on the proximal surfaces of abutments on the tooth-bounded side, the prosthesis will display a single path of insertion (arrow). In reality, most removable partial dentures seated position at a variety of angles. In Kennedy Class I arches, the ing planes have been prepared on the proximal surfaces of edentulous spaces are bounded by teeth at only one end. The reader should note that the ad these practitioners do not believe that stress directors are vantages presented for the different concepts are those necessary to account for this difference. This may be ac Advocates of the stress equalization approach to partial complished by depressing the mucosa during impression denture design emphasize that the vertical displaceability making procedures or by relining the denture base after it of a natural tooth is not as great as that of the soft tissues has been constructed. Advocates of this school Advocates of this theory believe that denture bases believe that forces applied to a removable partial denture formed over compressed tissues will show an increased are transmitted to the abutments. These practitioners also believe that rigid connections between denture bases and recognize that the prosthetic teeth and occlusal rests will direct retainers are damaging, and that stress directors are be positioned above the existing occlusal plane when the essential to protect the abutments (Fig 7-58).

Duress Alarm: A wireless duress alarm system should be provided in inpatient mental health facilities and is recommended for residential and outpatient mental health facilities treatment upper respiratory infection generic accupril 10mg otc. Portable duress devices allow staff to treatment 2 go accupril 10mg with amex discretely request assistance in a potentially threatening situation from any point within the unit or facility. The duress system for a unit should be monitored at the main nursing station and at a remote security post within the facility. In residential and outpatient mental health facilities, the monitoring should be located at the central reception/security post for the facility. In addition to portable duress alarms, duress push buttons should also be located under the counter of inpatient nursing stations, at reception desks and in mental health professional’s offices and exam rooms where appropriate. Waste Management General: All waste storage should be in a locked storage room to prevent patient access to these materials Medical Waste: Medical (biohazard) waste may be generated in examination rooms or in patient rooms. This waste will be collected in Sharps containers or other waste bags and transported using specially designated, closed containers to the soiled utility rooms. The waste is held there until it is transported via the loading dock to the medical waste handling facility. General Waste: General waste is generated in all spaces and is held in waste containers for collection. It is then collected by cart and transported via the loading dock to the waste handling facility. Recycling: Means of sorting, collecting, transporting and disposing of recyclable materials should be analyzed by locality and modified to suit local conditions and practices. Optional use of disposable and recyclable products is an important design consideration in recycling alternatives that impacts physical space for waste disposal volumes. Soiled Linen: Reusable soiled linens are generated in inpatient units, examination rooms, and resident rooms. They should be collected in carts or hampers and stored in a locked soiled utility room until transported to a soiled linen holding room near the loading dock for pick-up. Transportation Patient Transport: Typically inpatients, outpatients and domiciliary patients arrive at the main entrance via private transportation. The main entrance and ambulance/patient entrance should have a covered drop-off area. Clear site and facility organization, through the use of directional signage, is required to assist in directing the patient and others to their destination. Vehicles transporting residents for admission via the emergency entrance should be clearly directed to this location. Features such as clear access routes, public spaces, landmarks and signage are particularly important in the Mental Health Center to facilitate wayfinding. Staff facilities, such as locker room, on call rooms, and staff break rooms should be located convenient to the staff entry. Records: Patient records are maintained centrally and may be distributed and accessed electronically. Specimens: Effective means are necessary for maintaining and transporting specimens to insure quality. In outpatient clinics, a separate specimen collection rooms should be provided for male and female patients. Pharmaceuticals: Pharmaceuticals, including narcotics, are transported by pharmacy staff to individual patient units in locked transport containers. Clean supplies are transported via supply carts to the clean utility rooms on the individual patient units where supplies are accessed by staff. Linen: Delivery of clean linens and removal of soiled linens within an inpatient unit should be separated from resident/visitor traffic where possible. Sterile Supplies: Sterile items used in the exam or treatment rooms are transported via dedicated closed carts. The food will be brought in bulk on carts served from a steam table in the serving area. All food trays must be stored in the serving room which can be locked when not in use. Clean and soiled areas and products must be segregated to prevent cross contamination. Finished products should be transported only a short distance if they are to remain safe for consumption. Food waste will be collected from the serving area and taken to trash collection areas near loading docks where it is disposed according to facility policies. The patient room and adjoining bathroom illustrated in this guide plate are referred to as “standard” rooms and do not meet accessibility requirements. A minimum of 20% of the total bed space in a patient unit should be accommodated in accessible bedrooms with adjoining accessible bathrooms.

Problems Failure to wean include hypercapnia, thick tenacious secretions with mucous plugging, During the weaning process, the patient should be observed for early barotrauma, the requirement for heavy sedation and neuromuscular indications of fatigue or failure to wean. Tese signs include distress, blockade and hypotension from increased intra-thoracic pressure increasing respiratory rate, falling tidal volume and haemodynamic necessitating fuid loading and inotropic support. At this point it may be necessary to increase the level of respiratory support as, once concluSion exhausted, the respiratory muscles may take many hours to recover. The ability to ofer short term ventilatory support for patients with It is sensible to start the weaning process in the morning to allow close reversible respiratory failure is a major feature of intensive care monitoring of the patient throughout the day. This article has outlined the very basics of ventilatory it is common practice to increase ventilatory support overnight to management. Each clinician must become familiar with the machines allow adequate rest for the patient. It is vital that each unit has clearly defned criteria to tracheostomy in the intensive care unit decide which patients will beneft from ventilatory support. Tracheostomy allows a reduction in sedation and for successful and timely weaning of ventilation. It also allows efective tracheobronchial suction in patients who are unable to clear pulmonary ReFeRenceS secretions, either due to excessive secretion production or due to 1. Ventilation with Some patients have such severe respiratory illness that the techniques Lower Tidal Volumes as Compared with Traditional Tidal Volumes above cannot provide sufcient oxygen to prevent organ failure. Tracheotomy refers to the surgical opening of the trachea, while tracheostomy refers to the creation • There is an increased risk of respiratory tract of a stoma at the skin surface, which leads to the infection. Tracheostomies may be temporary or • Tere is a redundant area above tracheal opening permanent. A temporary tracheostomy may be used as and below the larynx in which mucus can a permanent tracheostomy, however there will still be accumulate and fall back into the lungs. Summary a communication between the pharynx and the lower • A foreign body reaction can occur, causing local this article describes the airway via the larynx. Meanwhile a large, retrospective cohort analysis prolonged ventilation including nearly 11,000 critically ill patients evaluated this is now the most common indication for the impact of tracheostomy timing on mortality. The timing of tracheostomy for this purpose is still The TracMan study was carried out in the United controversial (see later). Patients conditions associated with excessive tracheo-bronchial were randomised to early (n=455) or late (n=454) secretions requiring regular secretion clearance by tracheostomy. Tere was no signifcant diference in mortality between Rakesh Bhandary Tracheostomy may also be indicated as part of another the early and late tracheostomy groups at 30 days (139 Royal Victoria Infrmary procedure, for example, head and neck surgery. Contraindications to percutaneous tracheostomy following: “If you had 100 patients requiring tracheostomy, doing it emergency airway access (cricothyroidotomy preferred) early results in 2. Percutaneous tracheostomy was • Prothrombin time or activated partial thromboplastin time frst described in the late 1950s and 1960s, but received widespread greater than 1. Guidance from the Intensive Care Society points out that recommendation regarding the timing of tube changes is inconsistent and not evidence based. The frst change should not occur within 72 hours of the tracheostomy being sited and ideally not for 7 days after a percutaneous insertion. Emergency airway equipment, including a smaller tracheostomy tube and emergency drugs, should be percutaneous tracheostomy insertion immediately available during the change. Many commercial kits are available but they all employ a Seldinger The tracheostomy tube may be changed over a soft suction or airway guidewire technique for tracheostomy tube insertion. The use of a rigid gum vary slightly, depending upon operator preference and experience. A elastic bougie for this purpose may increase the risk of creating a false full description of this technique is beyond the scope of this article. If a soft tipped Ryle’s tube or similar is used, it cautionS and Relative contRaindicationS FoR may be reassuring to see fogging within that tube with respiration. If difculty is encountered in The cuf reduces aspiration and leakage of air during anaesthesia and replacing the tracheostomy tube, the clinical need for a tube must be positive pressure ventilation. If in doubt, re-intubation with an oral endotracheal tube tube when mechanical ventilation is not required or when there is may be required. Whilst most patients can be weaned by simply defating the cuf, it may still restrict airfow around Humidifcation the tube and changing to an uncufed or smaller tube may help. Cold and unfltered air is an irritant when inhaled and can lead to increased production and viscosity of secretions. This can be inner tube uncomfortable for the patient as well as causing tracheal mucosal The inner tube has the advantage of being easily and quickly removed keratinisation. The increasingly viscous secretions will be difcult to to relieve life threatening obstruction due to blood clots or secretions. This is usually via a nasogastric or nasojejunal tube, but it may be possible for patients with tracheostomies to be fed orally. However, swallowing is still adversely afected by the presence of a tracheostomy tube, which has a tendency to limit normal movement of the larynx. In addition, the infated cuf causes a sense of pressure in the upper oesophagus and the difculty that occurs with swallowing may result in an increased risk of aspiration of food into the lungs. Patients may be fed orally, with the cuf infated or partially defated, but staf must be alert to signs of aspiration, such as coughing, increased secretions and impaired gas exchange. It is prudent to commence with sips of water and some form of swallowing assessment. The size quoted is for the outer tube for single lumen devices, and the inner tube for double lumen devices, but only if the internal cannula is required for connection to a breathing circuit (Figure 2). Standard, dual cannula tracheostomy tube, A assembled; B dis assembled, with outer cannula (left), inner cannula (centre) and obturator (right). Fenestration Fenestrations maybe be single or multiple and are positioned at the site of maximum curvature of the tracheostomy tube. Speaking valves (like the Passy Muir valve) are one-way valves that are designed to be used with fenestrated tracheostomy tubes or unfenestrated tubes (with the cuf defated). Hence the expired air is forced through the larynx allowing the patient to phonate (Figure 6). Flexibility Flexible or reinforced tracheostomy tubes resemble reinforced endotracheal tubes. They are used in patients where a rigid tube may lie at an angle and cause abrasion or tube obstruction as its lumen abuts the posterior tracheal wall. This is inserted into the external orifce the stoma on the exterior can be adjusted in this variation of the of the tracheostomy tube (Copyright: Dr Rakesh Bhandary). This is useful in obese patients or those with local tissue swelling, where the soft tissue depth is increased (Figure 5). The 2 most common complications were oxygen desaturation in 14 patients (defned as a drop [even transient] to less than 90%) and bleeding in 12 patients (when intervention was required to control the bleeding). This is one of many studies that demonstrate a favourable complication rate for the percutaneous method compared to the surgical method. The complications of tracheostomy can be grouped as immediate, intermediate and long-term and are listed overleaf immediate or early complications Bleeding is the most common and the most commonly fatal Figure 5. An adjustable fange, fexible tracheostomy tube (Copyright: Dr complication of tracheostomy. Intraoperative bleeding is commonly due to cut edges of the vascular thyroid gland, anterior jugular vessels or Subglottic suction inferior thyroid vessels; bleeding in the immediate postoperative Some newer tracheostomy tubes include a subglottic suction port, the period may be exacerbated by emergence from anaesthesia and aim of which is to try and reduce the incidence of ventilator-associated hypertension. As bleeding may be controlled with pressure, local packing – perhaps with an endotracheal tube, the tracheostomy tube may also cause with dressings or Kaltostat soaked in dilute adrenaline, sutures or tracheal mucosal necrosis at the level of the cuf. Surgical emphysema Major bleeding can cause cardiovascular compromise, but may also may also be seen due to tight closure of tissue around the tube, tight cause respiratory difculties, particularly if clots form and obstruct packing material around the tube, or the false passage of the tube into any part of the airway. Malposition of the tracheostomy is always possible but should, in A tracheal granuloma may develop or healing may be delayed, leading theory, be minimised by the use of fbreoptic bronchoscopy for to a persistent tracheocutaneous fstula or sinus. Possibilities to consider include an obstructing granuloma previously intermediate complications held out of the way with the tube, bilateral vocal cord paralysis, Delayed haemorrhage maybe due to displaced blood clots or ligatures, fractured cartilage, and anxiety. Evaluation should include fbreoptic infective erosion into a blood vessels or rarely from a tracheoinnominate laryngoscopy and bronchoscopy through the stoma. Obese patients were at particular risk of such events and adverse and are familiar with a plan for its management. Understanding other two options, that air supply for speech is pulmonary, phonation that this can become a rapidly fatal complication, emphasis is placed sounds natural, and voice restoration occurs within 2 weeks of surgery. Two to three weeks post-operatively, an appropriately WeaninG and decannulation sized Bloom-Singer valve is inserted into the tracheoesphageal fstula. A Bloom-Singer valve is a hollow, 16 or 20-French, silicone tube that Decannulation allows the patient to resume breathing through the has a one-way fap valve positioned within its proximal tip. The valve upper airway and reduces dependence (psychological and otherwise) serves two purposes; frst, it allows the patient to phonate by allowing on the lower resistance of the tracheostomy tube. Patients can be trialled with increasing periods To phonate, the patient inhales air through the permanent stoma, of cuf defation. This allows patients to become re-accustomed to occludes the permanent stoma with the thumb and then exhales. The occluded stoma diverts air through the Bloom-Singer prosthesis Alternatively, an occlusion cap may be used which completely blocks and up the oesophagus to the mouth. This must be used with a fenestrated tube or an surfaces along the oesophagus and pharynx produces a variably husky unfenestrated tube with the cuf defated, and this greatly increases the or hoarse quality voice that is articulated by the tongue, lips, and teeth work of breathing, due to the increased airway resistance. What to do if a patient presents with displaced bloom Singer valve • Patient can tolerate cuf defation or capping of the tracheostomy tube. Two main problems are encountered if a patient presents with a displaced Bloom-Singer valve prosthesis. The patient is encouraged to gently press over this defect services, a self-retaining Foley’s catheter, equivalent in size to the B-S with whilst speaking or coughing. The balloon is infated with 3 ml of air, gently Equipment and expertise to re-secure the airway, either via the stoma retracted and taped to the side of the neck, while awaiting inter or via oral intubation, should be available. If the valve has been aspirated, it can be removed using a fbre-optic bronchoscope. Crit The basic options for speech rehabilitation after total largyngectomy Care Med 2008; 36: 2547-57.
