Tracheostomy management in the chronically ventilated patient

Safety of tracheostomy during extracorporeal membrane oxygenation support: A single-center experience

BACKGROUND

Some patients on extracorporeal membrane oxygenation (ECMO) require prolonged mechanical ventilation. An early tracheostomy strategy while on ECMO has appeared to be beneficial for these patients. This study aims to explore the safety of tracheostomy in ECMO patients.

METHODS

This is a retrospective observational single-center study.

RESULTS

Hundred and nine patients underwent tracheostomy (76 percutaneous and 33 surgical) during V-V ECMO support over an 8-year period. Patients with a percutaneous tracheostomy showed a significantly shorter ECMO duration [25.5 (17.3-40.1) vs 37.2 (26.5-53.2) days, p = 0.013] and a shorter ECMO-to-tracheostomy time [13.3 (8.5-19.7) vs 27.8 (16.3-36.9) days, p < 0.001] compared to those who underwent a surgical approach. There was no difference between the two strategies regarding both major and minor/no bleeding (p = 0.756). There was no difference in survival rate between patients who underwent percutaneous or surgical tracheostomy (p = 0.173). Patients who underwent an early tracheostomy (within 10 days from ECMO insertion) showed a significantly shorter hospital stay (p < 0.001) and a shorter duration of V-V ECMO support (p < 0.001). Our series includes 24 patients affected by COVID-19, who did not show significantly higher rates of major bleeding when compared to non-COVID-19 patients (p = 0.297). Within the COVID-19 subgroup, there was no difference in major bleeding rates between surgical and percutaneous approach (p = 1.0).

CONCLUSIONS

Percutaneous and surgical tracheostomy during ECMO have a similar safety profile in terms of bleeding risk and mortality. Percutaneous tracheostomy may favor a shorter duration of ECMO support and hospital stay and can be considered a safe alternative to surgical tracheostomy, even in COVID-19 patients, if relevant clinical expertise is available.

Laryngeal injury following endotracheal intubation: Have you considered reflux?

Laryngotracheal injury is an increasingly common complication of intubation and mechanical ventilation, with an estimated 87% of intubated and ventilated patients developing a laryngotracheal injury often preventing their rehabilitation from acute illness. Laryngotracheal injuries encompass a diverse set of pathologies including inflammation and oedema in addition to vocal cord ulceration and paralysis, granuloma, stenosis, and scarring. The existing literature has identified several factors including intubation duration, endotracheal tube size, type and cuff pressures, and technical factors including the skill and experience of the endoscopist. Despite these associations, a key aspect in the sequelae of laryngotracheal injuries is due to reflux and is not clearly related to iatrogenic and mechanical factors.Laryngopharyngeal reflux is a type of reflux that contaminates the upper aerodigestive tract. The combination of patient positioning and continuous nasogastric tube feeding act to affect the upper aerodigestive tract with acidic and non-acidic refluxate that causes direct and indirect mucosal injury impeding healing.Despite laryngopharyngeal reflux being an established and recognised causative factor of upper aerodigestive tract inflammatory pathology and laryngotracheal injury, it is very understudied in critical care. Further, there is yet to be an agreed pathway to assess, manage and prevent laryngotracheal injury in intubated and ventilated patients. The incidence of laryngopharyngeal reflux in the intubated and mechanically ventilated patient in the intensive care unit is currently unknown. Prospective studies may allow us to understand further potential mechanisms of upper aerodigestive tract injury due to laryngopharyngeal reflux and herald the development of preventative and management strategies of laryngopharyngeal reflux-mediated upper aerodigestive tract injury in critically ill patients.

Safety of Percutaneous vs Open Tracheostomy on Intubated Patients in ICU Setting: Which One is Better?

To study the safety of percutaneous vs open tracheostomy approaches on patients requiring long term ventilation in ICU setting. It is a prospective study done over a period of 2 years on 105 patients requiring long term ventilation in ICU set up in a tertiary care hospital. Patients were subjected to either open approach or percutaneous tracheostomy bedside in ICU itself. Then patients were followed during their hospital stay to look for any tracheostomy related complications. Data regarding age, gender, indications of long term ventilation and complications were compiled and analysis was done. It was found that most of the patients were of male gender (88.6%) in the age group of 50-59 years of age. The most common cause for tracheostomy was head injury secondary to road traffic accident, seen in 79 out of 105 cases. On comparing complications rate, there was no statistically significant difference in both the groups. However rate of peristomal infection is more with open approach group (P < 0.05). Percutaneous tracheostomy can be performed safely in ICU as a bedside procedure. There is significant reduction in peristomal infection with percutaneous tracheostomy and there is no significant difference in other complications between the two groups. Thus percutaneous tracheostomy is as safe as an open approach tracheostomy in properly selected cases.

Patient Outcomes following Immediate Tracheostomy and Emergency Decompressive Craniectomy in the Same Setting

Early tracheostomy is recommended for patients with severe traumatic brain injury or stroke. Tracheostomy in the same setting as emergency decompressive craniectomy, on the other hand, has never been investigated. Our goal was to compare the outcomes related to the duration of mechanical ventilation in patients who had immediate (IT) vs. early (ET) tracheostomy following an emergency decompressive craniectomy in a Neurosurgical centre in Sabah, Malaysia. We reviewed 135 patients who underwent emergency decompressive craniectomy for traumatic brain injury (TBI) and stroke patients between January 2013 and January 2018 in this retrospective cohort study. The cohort included 49 patients who received immediate tracheostomy (IT), while the control group included 86 patients who received a tracheostomy within 7 days of decompressive surgery (ET). The duration of mechanical ventilation, length of stay (LOS) in the critical-care unit, and intravenous sedation were significantly shorter in the IT group compared to the ET group, according to the study. There was no significant difference between the two groups in the incidence of ventilator-associated pneumonia (VAP), tracheostomy-related complications, or 30-day mortality rate. In conclusion, compared to early tracheostomy, immediate tracheostomy in the same setting as emergency decompressive craniectomy is associated with a shorter duration of mechanical ventilation and LOS in critical-care units with acceptable morbidity and mortality rates. This practise could be used in busy centres with limited resources, such as those where mechanical ventilators, critical-care unit beds, or OT wait times are an issue.

Long-Term Survival and Medical Costs of Patients with Prolonged Mechanical Ventilation and Tracheostomy: A Nationwide Cohort Study

Few large-scale studies have focused on tracheostomy in patients with prolonged mechanical ventilation. This retrospective population-based study extracted data from the longitudinal National Health Insurance Research Database in Taiwan to compare long-term mortality between patients on prolonged mechanical ventilation with and without tracheostomy and their related medical expenditures. Data on newly developed respiratory failure in patients on ventilator support were extracted from 1 January 2002 to 31 December 2008. Of 10,705 patients included, 1372 underwent tracheostomy (n = 563) or translaryngeal intubation (n = 779). Overall survival of the patients with tracheostomy was followed for 5 years. Average survival was 4.98 years for the patients with tracheostomy and 5.48 years for the patients with translaryngeal intubation (not significant). Sex, age, premium-based monthly salary difference, occupation, urbanization level, chronic obstructive pulmonary disease, chronic heart failure, chronic renal disease, and cerebrovascular diseases were significantly associated with mortality for endotracheal intubation. Male sex, chronic heart failure, chronic renal disease, age ≥45 years, and low income were associated with significantly higher mortality. Although total medical expenditures were higher for the patients with tracheostomy, annual medical expenditures were not significantly different. There were no differences in long-term mortality between the two groups.

Patient selection and preoperative evaluation of percutaneous dilation tracheostomy in the intensive care unit

Percutaneous dilation tracheostomy (PDT) is increasingly performed at the bedside of critically ill patients in the intensive care unit (ICU). PDT is safe overall and has a number of benefits compared to surgical tracheostomy. A tracheostomy tube has numerous advantages compared to an endotracheal tube, including decreased work of breathing, ease of connecting to a mechanical ventilator, improved patient comfort and pulmonary hygiene. Common patient populations include those unable to wean from mechanical ventilation, those requiring enhanced pulmonary hygiene, and those with progressive neuromuscular weakness. Clinicians performing this procedure should be familiar with common indications for performing tracheostomy as well as absolute and relative contraindications. Special patient populations, including those with morbid obesity, aberrant anatomic and vascular anatomy, cervical spine injury, and high ventilatory requirements, should be approached with careful planning. Pre-procedure evaluation for coagulopathy, including basic laboratory analysis and medication review, should be undertaken. Pre-procedure ultrasound may be used to more accurately identify landmarks and vascular structures. The optimal timing for performing PDT is unknown and depends on the unique characteristics of each patient, perceived natural history of the disease process being addressed and open conversations with the patient or surrogate decision maker. In this review, we identify patient populations most likely to benefit from PDT and outline data behind optimal timing, pre-procedural laboratory evaluation and patient specific factors that may influence procedural success.

Surgical airway procedures in emergency surgical patients: Results of what has become a back-up procedure

Background

Cricothyroidotomy and surgical tracheostomy are methods to secure airway patency. In emergency surgery, these methods are nowadays mostly reserved for patients unsuited for percutaneous procedures. Detailed description of complications and functional outcomes following both procedures is underreported in current literature. The aim of this study was to evaluate outcomes following cricothyroidotomy and tracheostomy in this presumed complex population.

Methods

In this retrospective cohort study, adult emergency surgical patients treated with cricothyroidotomy and/or surgical tracheostomy were included. Postoperative complications and functional outcomes in trauma and non-trauma patients were evaluated.

Results

Forty-one trauma patients and 11 non-trauma emergency surgical patients (mainly after elective onco-abdominal or vascular surgery) were included. Of 52 patients, seven underwent cricothyroidotomy pre-tracheostomy. Mortality was higher in non-trauma patients (p = 0.04) following both procedures. Over half of patients (56%, n = 29) regained unsupported airway patency with a tendency toward increased tracheostomy removal in trauma patients. Among complications, only pneumonia occurred frequently (60%, n = 31), with no relation to patient type. Other complications included local infection (5.8%, n = 4) and wound dehiscence (1.9%, n = 1). Adverse functional outcomes were frequently observed and were mild and self-limiting. Cervical spinal cord injury reduced overall unsupported airway patency (p = 0.01); with high cervical spinal cord injury related to adverse functional outcomes and increased home ventilation need.

Conclusions

No major procedure-related complications or functional adverse events were encountered following cricothyroidotomy and surgical tracheostomy, even though only complex patients were included. Only mild, self-limiting functional problems occurred, especially in trauma patients with cervical injury who underwent early tracheostomy by longitudinal incision. This information can aid clinicians in making tailor-made decisions for individual patients.

Tracheostomy Is Safe During Extracorporeal Membrane Oxygenation Support

Patients receiving extracorporeal membrane oxygenation (ECMO) often require prolonged mechanical ventilation. Providers may be reluctant to perform tracheostomies on patients during ECMO due to their tenuous clinical status and systemic anticoagulation. We report our experience with performing open and percutaneous tracheostomies on patients supported on ECMO from August 2009 to December 2017. Of the 127 patients who underwent tracheostomy during ECMO support, the median age was 42 years (interquartile range [IQR], 29-54), 99 (78%) patients had venovenous (VV) cannulation, 22 (17%) patients had venoarterial (VA) cannulation, and six (5%) patients had hybrid configurations. Percutaneous tracheostomy was performed in 110 (87%) patients. Median-activated partial thromboplastin time (aPTT) at the time of tracheostomy was 47.5 seconds (IQR, 41-57.6 seconds). The median time from ECMO initiation to tracheostomy was 7 days (IQR, 4-11 days). A total of 55 patients (43%) received packed red blood cell (pRBC) transfusions within 48 hours after tracheostomy with a median transfusion of 2 units (IQR, 1-3). There was no procedural mortality. Overall, 88 (69%) patients survived to decannulation and 74 (58%) survived to hospital discharge. Our experience with the largest published series of tracheostomies during ECMO demonstrates that excellent outcomes can be achieved without significant morbidity.

Prolonged Weaning: S2k Guideline Published by the German Respiratory Society

Mechanical ventilation (MV) is an essential part of modern intensive care medicine. MV is performed in patients with severe respiratory failure caused by respiratory muscle insufficiency and/or lung parenchymal disease; that is, when other treatments such as medication, oxygen administration, secretion management, continuous positive airway pressure (CPAP), or nasal high-flow therapy have failed. MV is required for maintaining gas exchange and allows more time to curatively treat the underlying cause of respiratory failure. In the majority of ventilated patients, liberation or "weaning" from MV is routine, without the occurrence of any major problems. However, approximately 20% of patients require ongoing MV, despite amelioration of the conditions that precipitated the need for it in the first place. Approximately 40-50% of the time spent on MV is required to liberate the patient from the ventilator, a process called "weaning". In addition to acute respiratory failure, numerous factors can influence the duration and success rate of the weaning process; these include age, comorbidities, and conditions and complications acquired during the ICU stay. According to international consensus, "prolonged weaning" is defined as the weaning process in patients who have failed at least 3 weaning attempts, or require more than 7 days of weaning after the first spontaneous breathing trial (SBT). Given that prolonged weaning is a complex process, an interdisciplinary approach is essential for it to be successful. In specialised weaning centres, approximately 50% of patients with initial weaning failure can be liberated from MV after prolonged weaning. However, the heterogeneity of patients undergoing prolonged weaning precludes the direct comparison of individual centres. Patients with persistent weaning failure either die during the weaning process, or are discharged back to their home or to a long-term care facility with ongoing MV. Urged by the growing importance of prolonged weaning, this Sk2 Guideline was first published in 2014 as an initiative of the German Respiratory Society (DGP), in conjunction with other scientific societies involved in prolonged weaning. The emergence of new research, clinical study findings and registry data, as well as the accumulation of experience in daily practice, have made the revision of this guideline necessary. The following topics are dealt with in the present guideline: Definitions, epidemiology, weaning categories, underlying pathophysiology, prevention of prolonged weaning, treatment strategies in prolonged weaning, the weaning unit, discharge from hospital on MV, and recommendations for end-of-life decisions. Special emphasis was placed on the following themes: (1) A new classification of patient sub-groups in prolonged weaning. (2) Important aspects of pulmonary rehabilitation and neurorehabilitation in prolonged weaning. (3) Infrastructure and process organisation in the care of patients in prolonged weaning based on a continuous treatment concept. (4) Changes in therapeutic goals and communication with relatives. Aspects of paediatric weaning are addressed separately within individual chapters. The main aim of the revised guideline was to summarize both current evidence and expert-based knowledge on the topic of "prolonged weaning", and to use this information as a foundation for formulating recommendations related to "prolonged weaning", not only in acute medicine but also in the field of chronic intensive care medicine. The following professionals served as important addressees for this guideline: intensivists, pulmonary medicine specialists, anaesthesiologists, internists, cardiologists, surgeons, neurologists, paediatricians, geriatricians, palliative care clinicians, rehabilitation physicians, intensive/chronic care nurses, physiotherapists, respiratory therapists, speech therapists, medical service of health insurance, and associated ventilator manufacturers.

Guidelines for Tracheostomy From the Korean Bronchoesophagological Society

The Korean Bronchoesophagological Society appointed a task force to develop a clinical practice guideline for tracheostomy. The task force conducted a systematic search of the Embase, Medline, Cochrane Library, and KoreaMed databases to identify relevant articles, using search terms selected according to key questions. Evidence-based recommendations for practice were ranked according to the American College of Physicians grading system. An external expert review and a Delphi questionnaire were conducted to reach a consensus regarding the recommendations. Accordingly, the committee developed 18 evidence-based recommendations, which are grouped into seven categories. These recommendations are intended to assist clinicians in performing tracheostomy and in the management of tracheostomized patients.

Classification of laryngeal injury in patients with prolonged intubation and to determine the factors that cause the injury

OBJECTIVE

This study aims to evaluate injuries occurring in the larynx of patients intubated in intensive care units for a long time.

STUDY DESIGN

Prospective clinical study.

SETTING

Tertiary hospital.

SUBJECT AND METHODS

Between April 15, 2019, and November 15, 2019, 40 patients who were hospitalized in intensive care units had a tracheotomy procedure due to prolonged intubation, and laryngeal structures were evaluated by direct laryngoscopy. The laryngeal structures were evaluated in four groups as glottic-supraglottic region, arytenoid vocal process, interaritenoid region and subglottic region. Edema, granulation and ulceration findings in these four regions were recorded. The injuries to the laryngeal structures were classified as stages 0-3. As a result of the data obtained, the relationship between the degree of laryngeal lesions and the factors that may cause these lesions was investigated.

RESULTS

According to our classification, nine patients had stage 1, 16 patients had stage 2 and 15 patients had stage 3 laryngeal injury. There was no significant relationship between the stage of laryngeal injury and age, sex and diameter of the intubation tube. There was a statistically significant relationship between laryngeal injury and the day the tracheotomy was performed (p = 0.007).

CONCLUSION

In patients that had prolonged endotracheal intubation, injury to the laryngeal structures is inevitable. To minimize this occurrence, tracheotomy should be performed for intubations that extend for more than seven days. When performing the tracheotomy, the laryngeal structures should be evaluated, necessary precautions should be taken for the traumatic lesions that are difficult to heal, and treatment should be started.

Improvement of the patient early mobilization protocol after oral and maxillofacial free flap reconstruction surgery

OBJECTIVE

There is lack of standardized management and mobilization strategies after oral and maxillofacial reconstruction surgery. We used prospective randomized controlled trials to explore improvements in postoperative mobilization protocol in such patients.

METHODS

A total of 149 patients were randomly divided into tracheotomy control group A (38 cases) and test group A (37 cases), nontracheotomy control group B (38 cases) and test group B (36 cases). Test group patients sat up in bed on the 2^nd day after surgery and performed off-bed activity on the 3^rd day, whereas control group patients sat up in bed on the 4^th day postoperatively and performed off-bed activity on the 6^th day. Objective evaluation included free flap success rate, postoperative complications, sleep time, and catheter removal time, among other parameters. Subjective evaluation included postoperative pain and comfort evaluation.

RESULTS

The success rate of free flaps was 97.3% in test group A and 100% in the other groups. In terms of mean sleep time, 4.6 ± 1.0 h in test group A, which was longer than 4.1 ± 1.0 h in control group A (P = 0.034); 5.7 ± 1.4 h in test group B, which was longer than 4.9 ± 1.7 h in control group B (P = 0.026). Early activity makes catheter removal time (tracheal incision, nasogastric tube, urethral catheter) shorter and gets higher comfort evaluation scores in both test groups versus control groups (P < 0.05).

CONCLUSIONS

The early mobilization protocol for patients undergoing free flap reconstruction was safe, and can effectively improve sleep, shorten the catheter indwelling time, and increase the patient's comfort level.

Laryngotracheal Stenosis in Early vs Late Tracheostomy: A Systematic Review

OBJECTIVE

For critically ill patients undergoing long-term mechanical ventilation, to determine whether early conversion from endotracheal intubation to tracheostomy reduces the incidence of laryngotracheal stenosis.

DATA SOURCES

MEDLINE, Embase, the Cochrane Central Register of Controlled Trials, and the Cumulative Index to Nursing and Allied Health Literature.

REVIEW METHODS

A systematic review in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and an assessment of bias were performed. Included studies reported outcomes of patients who were converted from endotracheal intubation to tracheostomy, compared early vs late tracheostomy, and reported the incidence of laryngotracheal stenosis and details of postoperative surveillance. Data were also collected for intensive care setting, method of tracheostomy, and timing of tracheostomy.

RESULTS

Seven articles met inclusion criteria: 2 randomized trials, 2 quasi-randomized trials, 1 prospective cohort, and 2 retrospective cohorts. A total of 966 patients were included in this analysis (496 in the early tracheostomy group and 470 in the late tracheostomy group). The mean incidence of laryngotracheal stenosis was 8.9% (range, 0%-20.8%), with a mean incidence of 8.1% in early tracheostomy groups and 10.9% in late tracheostomy groups. In studies with the least risk of bias, there were no differences in the incidence of laryngotracheal stenosis in patients who underwent early vs late tracheostomy.

CONCLUSION

In critically ill patients undergoing long-term mechanical ventilation, early conversion to tracheostomy within 7 days of intubation does not significantly decrease the risk of laryngotracheal stenosis compared to later conversion as defined by the included studies.

Percutaneous Dilational Tracheostomy

Tracheostomy tubes can be inserted surgically or percutaneously via percutaneous dilational tracheostomy (PDT). Tracheostomy is performed for upper airway obstruction, though more often to allow prolonged mechanical ventilation in place of endotracheal tubes. Preparation, performance, and postoperative management for PDT are best provided by a multidisciplinary team. Although PDT is a safe procedure in the hands of experienced operators, both early and late complications can arise. Caution must also be taken during early tracheostomy tube exchange given that immaturity of the stomal tract can risk loss of the airway.

Early Versus Late Tracheostomy After Decompressive Craniectomy

Objective

The goal of this study was to determine the efficacy of early tracheostomy (i.e., ≤ 10 days of intubation) compared with a late tracheostomy (> 10 days of intubation) with regards to timing, frequency of ventilator-associated pneumonia (VAP), mortality rate, and hospital stay in patients who received decompressive craniectomy.

Study design

We conducted a retrospective study of data from 168 patients who underwent decompression in the department of critical care medicine at Shifa International Hospital, Islamabad, Pakistan, from January 2017 to December 2017.

Materials and methods

The study included men and women over the age of 18 years who had undergone tracheostomy following decompressive craniectomy in the intensive care unit as a result of stroke, traumatic brain injury, or acute severe injury. Data were analyzed using IBM SPSS Statistics for Windows, Version 23.0 (IBM Corp., Armonk, NY, US). We also applied the Chi-square test, and p ≤ 0.05 was considered significant.

Results

Of 168 patient records reviewed, tracheostomy was performed in 48 patients (21 men, 27 women). In the 48 tracheostomy patients, 15 (31%) were early tracheostomies and 33 (69%) were late tracheostomies. The mean age of patients was 44 ± 11 years. Twenty-eight patients (58.3%) were in the younger age group (age 18 to 45 years) and 20 patients (41.7%) were in the older age group (age > 45 years). Patients who received an early tracheostomy spent significantly less time on a ventilator (≤ 12 days) than those patients receiving a late tracheostomy (> 12 days, p = 0.004). The early tracheostomy group also had a lower incidence rate of VAP than patients with a late tracheostomy (𝑥² = 7.855, p = 0.005). Patients who received an early tracheostomy had lower mortality rates than those who received late tracheostomies (𝑥² = 6.158, p = 0.013). Finally, the length of hospital stay was ≤ 15 days for patients who received early tracheostomies; most patients who received a late tracheostomy had a hospital stay of > 15 days (𝑥² =11.965, p = 0.001).

Conclusions

Performing a tracheostomy within 10 days of intubation following decompressive craniectomy significantly reduced ventilator time, mortality, the incidence of VAP, and length of hospital stay. Given the potential benefits of early tracheostomy in critical care patients following decompressive craniectomy, physicians should consider early tracheostomy in appropriate cases.

Adult Head and Neck Health Care Needs for Individuals with Complex Chronic Conditions of Childhood

Millions of adults in the United States are currently living with what is termed chronic childhood conditions-childhood-onset conditions, about which adult providers often receive minimal training-and another half million youths with special health care needs enter adulthood each year and will undergo transition from pediatric to adult care. Here, the authors review the important otolaryngologic manifestations of several of these chronic childhood conditions, including autism spectrum disorder, cerebral palsy, and Down syndrome, as well as the primary care providers' role in caring for transitioning tracheostomy-dependent patients.

Heated air humidification versus cold air nebulization in newly tracheostomized patients

Background

After tracheostomy, the airway lacks an essential mechanism for warming and humidifying the inspired air with the consequent functional impairment and discomfort. The purpose of this study was to compare airway hydration with cold‐air nebulization versus heated high‐flow humidification on medical interventions and tracheal ciliary beat frequency (CBF).

Methods

Newly tracheostomized patients (n = 20) were treated either with cold‐air nebulization or heated humidification. The number of required tracheal suctioning procedures to clean the trachea and tracheal CBF were assessed.

Results

The number of required suctions per day was significantly lower in the heated humidification group with medians 3 versus 5 times per day. Mean CBF was significantly higher in the heated humidification group (6.36 ± 1.49 Hz) compared to the cold‐air nebulization group (3.99 ± 1.39 Hz).

Conclusion

The data suggest that heated humidification enhanced mucociliary transport leading to a reduced number of required suctioning procedures in the trachea, which may improve postoperative patient care.

Tracheostomy Update: When and How

Tracheostomy remains one of the most commonly performed surgical procedures in the setting of acute respiratory failure. Tracheostomy literature focuses on 2 aspects of this procedure: when (timing) and how (technique). Recent trials have failed to demonstrate an effect of tracheostomy timing on most clinically important endpoints. Nonetheless, relative to continued translaryngeal intubation, studies suggest that tracheostomy use is associated with less need for sedation and enhanced patient comfort. Evidence likewise suggests that percutaneous dilational tracheostomy is advantageous with respect to cost and complication profile and should be considered the preferred approach in appropriately selected patients.

The practice of tracheostomy decannulation-a systematic review

Decannulation is an essential step towards liberating tracheostomized patients from mechanical ventilation. However, despite its perceived importance, there is no universally accepted protocol for this vital transition. Presence of an intact sensorium coordinated swallowing and protective coughing are often the minimum requirements for a successful decannulation. Objective criteria for each of these may help better the clinical judgement of decannulation. In this systematic review on decannulation, we focus attention to this important aspect of tracheostomy care.

Essential principles: tracheostomy care in the adult patient

AIM

This article aims to guide the nurse caring for a tracheostomy patient, following the main principles of nursing care.

BACKGROUND

Tracheostomy is a surgical procedure to create an opening in the anterior wall of the trachea. Owing to improvement in technological support, the number of adult patients receiving a tracheostomy has increased. This requires the critical care nurse to have an understanding of the essential principles of care for a patient with a tracheostomy tube in situ.

DESIGN AND METHOD

Literature search was conducted in Medline and Cinahl using the search terms tracheostomy OR tracheotomy AND procedure/nursing care/experience limited to English language and adult. Owing to the lack of empirical research on the care of patients with tracheostomy, evidence is limited and therefore expert consensus is utilized in much of the article.

RESULTS

This article considers the indications for a tracheostomy, identifies the component parts of a tracheostomy tube, discusses 12 essential principles of care for a patient with a tracheostomy tube in situ, and finally briefly describes the nurse's role in an emergency and when discharging a patient with a tracheostomy tube to a ward.

CONCLUSION

Performing a tracheostomy has an enormous impact on patients and their care.

RELEVANCE TO CLINICAL PRACTICE

Nurses caring for patients with tracheostomy require an appreciation of the breadth of knowledge needed to provide individual and safe care. It is also important to appreciate the lack of empirical evidence on which to base that care.

Early versus late tracheostomy for critically ill patients

BACKGROUND

Long-term mechanical ventilation is the most common situation for which tracheostomy is indicated for patients in intensive care units (ICUs). 'Early' and 'late' tracheostomies are two categories of the timing of tracheostomy. Evidence on the advantages attributed to early versus late tracheostomy is somewhat conflicting but includes shorter hospital stays and lower mortality rates.

OBJECTIVES

To evaluate the effectiveness and safety of early (≤ 10 days after tracheal intubation) versus late tracheostomy (> 10 days after tracheal intubation) in critically ill adults predicted to be on prolonged mechanical ventilation with different clinical conditions.

SEARCH METHODS

This is an update of a review last published in 2012 (Issue 3, The Cochrane Library) with previous searches run in December 2010. In this version, we searched the Cochrane Central Register of Controlled Trials (CENTRAL) (2013, Issue 8); MEDLINE (via PubMed) (1966 to August 2013); EMBASE (via Ovid) (1974 to August 2013); LILACS (1986 to August 2013); PEDro (Physiotherapy Evidence Database) at www.pedro.fhs.usyd.edu.au (1999 to August 2013) and CINAHL (1982 to August 2013). We reran the search in October 2014 and will deal with any studies of interest when we update the review.

SELECTION CRITERIA

We included all randomized and quasi-randomized controlled trials (RCTs or QRCTs) comparing early tracheostomy (two to 10 days after intubation) against late tracheostomy (> 10 days after intubation) for critically ill adult patients expected to be on prolonged mechanical ventilation.

DATA COLLECTION AND ANALYSIS

Two review authors extracted data and conducted a quality assessment. Meta-analyses with random-effects models were conducted for mortality, time spent on mechanical ventilation and time spent in the ICU.

MAIN RESULTS

We included eight RCTs (N = 1977 participants). At the longest follow-up time available in these studies, evidence of moderate quality from seven RCTs (n = 1903) showed lower mortality rates in the early as compared with the late tracheostomy group (risk ratio (RR) 0.83, 95% confidence interval (CI) 0.70 to 0.98; P value 0.03; number needed to treat for an additional beneficial outcome (NNTB) ≅ 11). Divergent results were reported on the time spent on mechanical ventilation and no differences were noted for pneumonia, but the probability of discharge from the ICU was higher at day 28 in the early tracheostomy group (RR 1.29, 95% CI 1.08 to 1.55; P value 0.006; NNTB ≅ 8).

AUTHORS' CONCLUSIONS

The whole findings of this systematic review are no more than suggestive of the superiority of early over late tracheostomy because no information of high quality is available for specific subgroups with particular characteristics.

Early versus Late Tracheostomy

Objective

To investigate whether early tracheostomy leads to improved outcomes compared with late tracheostomy.

Data Sources

Ovid MEDLINE (including PubMed), Embase, and the Cochrane Central Register of Controlled Trials.

Review Methods

A systematic search was performed of the above-mentioned databases according to PRISMA guidelines. Data were collected on the following outcomes of interest: hospital mortality, intensive care unit length of stay, length of mechanical ventilation, incidence of pneumonia, laryngotracheal injury, and sedation use. Analysis was performed using the RevMan 5 software (Cochrane Collaboration, Oxford, England).

Results

Eleven studies were included for analysis. There was a significant decrease in the intensive care unit length of stay in the early tracheostomy group (weighted mean difference, −9.13 days; 95% confidence interval [CI], −17.55 to −0.70; P = .03). There was no significant difference in hospital mortality (relative risk, 0.84; 95% CI, 0.67 to 1.04; P = .11). A pooled analysis was not performed for the incidence of pneumonia or length of mechanical ventilation, secondary to considerable heterogeneity among the studies. None of the studies reporting laryngotracheal outcomes found a significant difference between the early and late tracheostomy groups, whereas all 3 studies reporting sedation use found a significant decrease in the early tracheostomy group.

Conclusion

Early tracheostomy performed within 7 days of intubation was associated with a decrease in intensive care unit length of stay. No difference was found in hospital mortality. Insufficient data currently exist to make conclusions about the effect of early tracheostomy on the incidence of pneumonia, length of mechanical ventilation, laryngotracheal injury, or sedation use.

Tracheotomy is one of the most frequent surgical procedures performed in critically ill patients hospitalized at intensive care units. The ideal timing for a tracheotomy is still controversial, despite decades of experience.

OBJECTIVE

To determine the impact of performing early tracheotomies in critically ill patients on duration of mechanical ventilation, intensive care unit stay, overall hospital stay, morbidity, and mortality.

METHODS

Retrospective and observational study of cases subjected to elective tracheotomy at one of the intensive care units of this hospital during five consecutive years. The patients were stratified into two groups: early tracheotomy group (tracheotomy performed from day one up to and including day seven of mechanical ventilation) and late tracheotomy group (tracheotomy performed after day seven). The outcomes of the groups were compared.

RESULTS

In the early tracheotomy group, there was a statistically significant reduction in duration of mechanical ventilation (6 days vs. 19 days; p<0.001), duration of intensive care unit stay (10 days vs. 28 days; p=0.001), and incidence of ventilator-associated pneumonia (1 case vs. 44 cases; p=0.001).

CONCLUSION

Early tracheotomy has a significant positive impact on critically ill patients hospitalized at this intensive care unit. These results support the tendency to balance the risk-benefit analysis in favor of early tracheotomy.

Tracheostomy timing in traumatic brain injury: a propensity-matched cohort study

BACKGROUND

The optimal timing of tracheostomy in patients with severe traumatic brain injury (TBI) is controversial; observational studies have been challenged through confounding by indication, and interventional studies have rarely enrolled patients with isolated TBI.

METHODS

We included a cohort of adults with isolated TBI who underwent tracheostomy within 1 of 135 participating centers in the American College of Surgeons' Trauma Quality Improvement Program, during 2009 to 2011. Patients were classified as having undergone early tracheostomy (ET, ≤8 days) versus late tracheostomy (>8 days). Outcomes were compared between propensity score-matched groups to reduce confounding by indication. In sensitivity analyses, we used time-dependent proportional hazard regression to address immortal time bias and assessed the association between hospital ET rate and patients' outcome at the hospital level.

RESULTS

From 1,811 patients, a well-balanced propensity-matched cohort of 1,154 patients was defined. After matching, ET was associated with fewer mechanical ventilation days (median, 10 days vs. 16 days; rate ratio [RR], 0.70; 95% confidence interval [CI], 0.66-0.75), shorter intensive care unit stay (median, 13 days vs. 19 days; RR, 0.70; 95% CI, 0.66-0.75), shorter hospital length of stay (median, 20 days vs. 27 days; RR, 0.80; 95% CI, 0.74-0.86), and lower odds of pneumonia (41.7% vs. 52.7%; odds ratio [OR], 0.64; 95% CI, 0.51-0.80), deep venous thrombosis (8.2% vs. 14.4%; OR, 0.53; 95% CI, 0.37-0.78), and decubitus ulcer (4.0% vs. 8.9%; OR, 0.43; 95% CI, 0.26-0.71) but no significant difference in pulmonary embolism (1.8% vs. 3.3%; OR, 0.52; 95% CI, 0.24-1.10). Hospital mortality was similar between both groups (8.4% vs. 6.8%; OR, 1.25; 95% CI, 0.80-1.96). Results were consistent using several alternate analytic methods.

CONCLUSION

In this observational study, ET was associated with a shorter duration of mechanical ventilation, intensive care unit stay, and hospital stay but not hospital mortality. ET may represent a mechanism to reduce in-hospital morbidity for patients with TBI.

LEVEL OF EVIDENCE

Therapeutic study, level II.

Clinical consensus statement: tracheostomy care

OBJECTIVE

This clinical consensus statement (CCS) aims to improve care for pediatric and adult patients with a tracheostomy tube. Approaches to tracheostomy care are currently inconsistent among clinicians and between different institutions. The goal is to reduce variations in practice when managing patients with a tracheostomy to minimize complications.

METHODS

A formal literature search was conducted to identify evidence gaps and refine the scope of this consensus statement. The modified Delphi method was used to refine expert opinion and facilitate a consensus position. Panel members were asked to complete 2 scale-based surveys addressing different aspects of pediatric and adult tracheostomy care. Each survey was followed by a conference call during which results were presented and statements discussed.

RESULTS

The panel achieved consensus on 77 statements; another 39 were dropped because of lack of consensus. Consensus was reached on statements that address initial tracheostomy tube change, management of emergencies and complications, prerequisites for decannulation, management of tube cuffs and communication devices, and specific patient and caregiver education needs.

CONCLUSION

The consensus panel agreed on statements that address the continuum of care, from initial tube management to complications in children and adults with a tracheostomy. The panel also highlighted areas where consensus could not be reached and where more research is needed. This consensus statement should be used by physicians, nurses, and other stakeholders caring for patients with a tracheostomy.

Early versus late tracheostomy for critically ill patients

BACKGROUND

Long-term mechanical ventilation is the most common situation where tracheostomy is indicated for patients in intensive care units (ICU). 'Early' and 'late' tracheostomies are two categories of the timing of tracheostomy. The evidence on the advantages attributed to early over late tracheostomy is somewhat conflicting but includes shorter hospital stays and lower mortality rates.

OBJECTIVES

To evaluate the effectiveness and safety of early (≤ 10 days after intubation) versus late tracheostomy (> 10 days after intubation) in critically ill adult patients predicted to be on prolonged mechanical ventilation and with different clinical conditions.

SEARCH METHODS

We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2010, Issue 12); MEDLINE (via PubMed) (1966 to December 2010); EMBASE (via Ovid) (from 1974 to December 2010); LILACS (1986 to December 2010); PEDro (Physiotherapy Evidence Database) at www.pedro.fhs.usyd.edu.au (1999 to December 2010) and CINAHL (1982 to December 2010).

SELECTION CRITERIA

We included all randomized or quasi-randomized controlled trials which compared early tracheostomy (two to10 days after intubation) against late tracheostomy (> 10 days after intubation) for critically ill adult patients expected to be on prolonged mechanical ventilation. There was no language restriction.

DATA COLLECTION AND ANALYSIS

Two authors extracted data and conducted a quality assessment. Meta-analyses using the random-effects model were conducted for mortality and pneumonia.

MAIN RESULTS

We included four studies, with a high risk of bias, in which a total of 673 patients were randomized to either early or late tracheostomy. We could not pool data in a meta-analysis because of clinical, methodological and statistical heterogeneity between the included studies. There is no strong evidence for real differences between early and late tracheostomy in the primary outcome of mortality. In one study a statistically significant result favouring early tracheostomy was observed in the outcome measuring time spent on ventilatory support (mean difference (MD) -9.80 days, 95% CI -11.48 to -8.12, P < 0.001).

AUTHORS' CONCLUSIONS

Updated evidence is of low quality, and potential differences between early and late tracheostomy need to be better investigated by means of randomized controlled trials. At present there is no specific information about any subgroup or individual characteristics potentially associated with better outcomes with either early or late tracheostomy.

Examination of non-clinical factors affecting tracheostomy practice in an academic surgical intensive care unit

OBJECTIVES

To gain insight into nonclinical factors potentially influencing tracheostomy practice and determine whether a specialized consultation form impacts tracheostomy utilization.

DESIGN

Prospective, observational.

SETTING

Surgical intensive care unit (SICU).

PATIENTS

Patients requiring mechanical ventilatory support. Data abstracted from the Project Impact administrative database served as a practice benchmark.

INTERVENTIONS

Prospective data collection, completion of online survey, and implementation of specialized tracheostomy consultation form.

MEASUREMENTS AND MAIN RESULTS

Data were prospectively collected on 539 patients and 13 attending intensivists. Our SICU tracheostomy rate (54.2%) exceeded that of 18 comparable ICUs participating in Project Impact (13.9%, p < .001). We attempted to identify factors that might account for liberal tracheostomy use. In 41.5% (+/-0.6%) of patients undergoing tracheostomy, extubation had not occurred despite successful completion of spontaneous breathing trial on >or=1 occasion, a rate that varied significantly among attending intensivists responsible for decision making for this procedure (p < .001). Attending intensivists and postgraduate surgical trainees with SICU experience were surveyed to better understand perceptions of tracheostomy practice. Most respondents (96.1%) reported relying on spontaneous breathing trial to guide decision for extubation, 72.6% estimated that <or=25% of patients successfully completed spontaneous breathing trial but did not proceed to immediate extubation, 86.3% estimated that <or=25% of such patients undergo tracheostomy, and 58.8% felt an acceptable benchmark for this practice was <or=10%. In most survey domains, respondents' perceptions underestimated actual practice. Implementation of a specialized tracheostomy consultation form did not impact tracheostomy utilization.

CONCLUSIONS

We identified variation among clinicians with respect to tracheostomy practice as well as discrepancies between perceptions of this practice and actual utilization. These factors may underlie the liberal use of this procedure in our SICU. Processes for providing accurate physician feedback may assist in optimizing tracheostomy use.

Tracheostomy protocol: experience with development and potential utility

OBJECTIVES

To examine the feasibility and potential utility of a tracheostomy protocol based on a standardized approach to ventilator weaning.

DESIGN

Prospective, observational data collection.

SETTING

Academic medical center.

PATIENTS

Surgical intensive care unit patients requiring mechanical ventilatory support.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

Tracheostomy practice in 200 patients was analyzed in relation to spontaneous breathing trial (SBT) weaning. Decision for, and performance of, tracheostomy occurred (median [interquartile range]) 5.0 (3.75-8.0) and 7.0 (5.0-10.0) days following initiation of mechanical ventilation, respectively. Duration of mechanical ventilation was greater in tracheostomy compared with nontracheostomy patients (15.0 [11.0-19.0] vs. 6.0 [4.0-8.0], p < .001). For patients requiring ventilatory support for > or = 20 days, 100% of patients were maintained via tracheostomy. A protocol based on weaning performance, which included technical considerations, was developed. Individuals who failed preliminary weaning assessment or SBT for 3 successive days following 5 days (nonreintubated patients) or 3 days (reintubated patients) of ventilatory support met tracheostomy criteria. The protocol was implemented on a pilot basis in 125 individuals. Of the 55 (44.0%) patients undergoing tracheostomy, 25 (45.5%) did so consistent with criteria. Eighteen patients (32.7%) underwent tracheostomy before the time interval of data collection targeting weaning protocol performance, and 12 patients (21.8%) passed SBT on one or more occasions, were not extubated, and proceeded to tracheostomy.

CONCLUSIONS

A standardized approach in which the decision for tracheostomy is based on objective measures of weaning performance may be a means of using this procedure more consistently and effectively.

Tracheostomy decannulation: marathons and finish lines

Critically ill patients with a tracheostomy who are recovering from respiratory failure eventually require evaluation for airway decannulation. Although expert recommendations guide decisions for managing decannulation, few if any investigative data exist to inform evidence-based care. Consequently, practice variation limits the effectiveness of weaning from tracheostomy. In an investigation reported in this issue of Critical Care, the authors surveyed experienced physicians and respiratory therapists to assess their opinions on managing airway decannulation and identified several clinical factors that they recommend for selecting patients for tracheostomy tube removal. The authors propose that these factors can assist with designing clinical trials of tracheostomy decannulation. Pending completion of such studies, this report underscores the problem of practice variation in managing tracheotomized patients after critical illness. An important implication of the study is that care providers should recognize our knowledge deficit and develop systematic protocols for improving patient care using quality improvement techniques. Such models exist in the literature for adult patients and for children with tracheostomies who are managed by expert teams with requisite knowledge and skills.

Tracheotomy: clinical review and guidelines

Tracheotomy is a commonly performed procedure. The Belgian Society of Pneumology (BVP-SBP) and the Belgian Association for Cardiothoracic Surgery (BACTS) developed guidelines on tracheotomy for mechanical ventilation in adults. The levels of evidence as developed by the American College of Chest Physicians (ACCP) were used. The members of the guideline committee reviewed peer-reviewed publications on this subject. After discussion, a proposal of guidelines was placed on the website for remarks and suggestions of the members. Remarks and suggestions were discussed and used to adapt the guidelines when judged necessary. The different techniques of tracheotomy are described. The potential advantages and disadvantages of surgical and percutaneous tracheotomy versus endotracheal intubation are discussed. An overview of early and late complications is given. Low-pressure, high-volume cuffs should be used. The cuff pressure should be monitored with calibrated devices and recorded at least once every nursing shift and after manipulation of the tracheotomy tubes. Inspired gas should be humidified and heated. Regarding the timing of tracheotomy there are not enough well-designed studies to establish clear guidelines. Therefore, the timing of tracheotomy should be individualised. In critically ill adult patients requiring prolonged mechanical ventilation, tracheotomy performed at an early stage (within the first week) may shorten the duration of artificial ventilation and length of stay in intensive care. Percutaneous dilatational tracheotomy (PDT) appears to be at least as safe as surgical tracheotomy (ST) as measured in terms of peri-procedural complications. With PDT, less wound infection is observed. When PDT is compared to ST performed in the operating room, PDT is less expensive, reduces the time between the decision and the performance of tracheotomy and has a lower mortality rate. Different techniques of PDT are discussed. We recommend performing PDT under bronchoscopic guidance. Because of its technical simplicity and short procedure time, the modified Ciaglia Blue Rhino technique is advocated as technique of choice. PDT should be considered the procedure of choice in elective non-urgent tracheotomy. There are some relative contraindications for PDT, but with growing experience, they become less frequent.

Dysphagic patients with tracheotomies: a multidisciplinary approach to treatment and decannulation management

In 2000 a multidisciplinary protocol for weaning dysphagic patients from the tracheotomy tube and a decannulation decision chart created according to principles of the F.O.T.T.((R)) Concept (Face and Oral Tract Therapy) were introduced in the Swiss Neurological Rehabilitation Centre REHAB in Basel. In the present study we introduce these guidelines and present an evaluation of the treatment and decannulation procedure. We retrospectively compared data from patients before and after introduction of the multidisciplinary procedure with regard to mean cannulation times and success of decannulation. Furthermore, we analyzed the rehabilitation progress of the group who underwent multidisciplinary treatment as well as the participation of the speech language therapist. The results show that the treatment introduced to improve swallowing functions and wean patients from the tracheotomy tube led to a fast and safe decannulation of our patients. The mean length of cannulation time was reduced significantly. After decannulation the patients showed clear functional improvements. Interdisciplinary treatment using the approach discussed in this study can be considered efficient and an important basis for further functional progress in the rehabilitation process.

Management of patients requiring prolonged mechanical ventilation: report of a NAMDRC consensus conference

Patients requiring prolonged mechanical ventilation (PMV) are rapidly increasing in number, as improved ICU care has resulted in many patients surviving acute respiratory failure only to then require prolonged mechanical ventilatory assistance during convalescence. This patient population has clearly different needs and resource consumption patterns than patients in acute ICUs, and specialized venues, management strategies, and reimbursement schemes for them are rapidly emerging. To address these issues in a comprehensive way, a conference on the epidemiology, care, and overall management of patients requiring PMV was held. The goal was to not only review existing practices but to also develop recommendations on a variety of assessment, management, and reimbursement issues associated with patients requiring PMV. Formal presentations were made on a variety of topics, and writing groups were formed to address three specific areas: epidemiology and outcomes, management and care settings, and reimbursement. Each group was charged with summarizing current data and practice along with formulation of recommendations. A working draft of the products of these three groups was then created and circulated among all participants. The document was reworked with input from all concerned until a final product with consensus recommendations on 12 specific issues was achieved.

Predictive factors for tracheostomy in neurocritical care patients with spontaneous supratentorial hemorrhage

BACKGROUND

Up to 30% of patients with supratentorial intracerebral hemorrhage (ICH) require mechanical ventilation during the course of treatment. For these patients, tracheostomy is necessary in cases of protracted weaning. As only limited data exist about predictors for a tracheostomy in patients with ICH, the aim of this study was to investigate the frequency of tracheostomy and clinical findings that increase the risk for a tracheostomy in patients with supratentorial hemorrhage.

METHODS

A total of 392 patients with supratentorial ICH were analyzed. The parameters age, gender, chronic obstructive pulmonary disease (COPD), Glasgow Coma Scale on admission, ganglionic or non-ganglionic localization, presence of ventricular hemorrhage, hydrocephalus, hematoma volume, and hematoma evacuation were investigated. The effects on the end-point tracheostomy were analyzed using multivariate regression analyses.

RESULTS

The overall need for tracheostomy was 9.9% (16.3% in patients with ganglionic hemorrhage versus 2.8% in patients with non-ganglionic hemorrhages). 31% of the ventilated patients required tracheostomy. The risk for tracheostomy was increased eightfold in patients who developed hydrocephalus. The presence of ventricular blood, in general, showed no significant impact on the need for tracheostomy, whereas hemorrhage extending into the third and fourth ventricles in conjunction with hydrocephalus increased the risk for tracheostomy. The hematoma volume correlated positively with the risk for tracheostomy.

CONCLUSIONS

Our study demonstrates that approximately 10% of patients with ICH require tracheostomy during the course of their disease. Presence of COPD, hematoma volume, ganglionic location of the hematoma, and the development of hydrocephalus are predisposing factors for tracheostomy.

Relationship between tracheostomy timing and duration of mechanical ventilation in critically ill patients

OBJECTIVE

Tracheostomy practice in the setting of critical illness is controversial because evidence demonstrating unequivocal benefit is lacking. We undertook this study to determine the relationship between tracheostomy timing and duration of mechanical ventilation, intensive care unit length of stay, and hospital length of stay and to evaluate the relative influence of clinical and nonclinical factors on tracheostomy practice.

DESIGN

Analysis of Project Impact, a multi-institutional critical care administrative database.

SETTING

Medical school.

PATIENTS

Data from 43,916 patients were reviewed.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

Tracheostomy was performed in 2,473 (5.6%) of 43,916 patients analyzed. Tracheostomy patients had a higher survival rate than nontracheostomy patients (78.1 vs. 71.7%, p < .001) and underwent this procedure following a median (25th-75th percentile) of 9.0 (5.0-14.0) days of ventilatory support. Tracheostomy frequency and timing varied significantly comparing patient, intensive care unit, and hospital characteristics (p < .05 for all). Tracheostomy timing correlated significantly with duration of mechanical ventilation (r = .690), intensive care unit (r = .610), and hospital length of stay (r = .341, p < .001 for all). At most, 22% of patients were supported via tracheostomy at any given time. Although a minority, tracheostomy patients accounted for 26.2%, 21.0%, and 13.5% of all ventilator, intensive care unit, and hospital days, respectively.

CONCLUSIONS

Although practice varies substantially, tracheostomy timing appears significantly associated with duration of mechanical ventilation, intensive care unit length of stay, and hospital length of stay. These findings emphasize the need for an adequately supported multiple-center trial to better define patient selection for tracheostomy and to test the hypothesis that timing of this procedure influences clinically important outcomes.

La gestion de la trachéotomie chez les patients adultes sous assistance ventilatoire à domicile

INTRODUCTION

Despite a large increase in the use of long term non-invasive ventilation domiciliary ventilation via a tracheostomy remains necessary in certain cases of severe respiratory insufficiency. The object of this article is to describe the technical and human management required in domiciliary ventilation by tracheostomy.

PERSPECTIVES

From the setting up of invasive ventilation in the home the choice of a tracheostomy tube to suit the patient and the management of the cuff by the patient or the family requires special attention by the prescribing physician. Currently humidification of the circuit is usually achieved by means of a hot water humidifier. Aspiration techniques, the changing and cleaning of the tracheostomy tube and the correct use of the speaking system need to be taught to the patient and the relatives. The main complications of domiciliary ventilation by tracheostomy are linked to the presence of the tube in the trachea and either mechanical (stenosis, granulomata, tracheal-oesophageal fistula) or infections.

CONCLUSIONS

The prescribing physician should call on health care providers whose staff are trained in domiciliary ventilation by tracheostomy and include in his team nurses who can continue the education of the patient and relatives.

Contemporary issues in adult tracheostomy management

Airway assessment and management is one of the primary responsibilities of nurses caring for the critically ill adult. Common types of artificial airways, such as endotracheal and tracheostomy tubes, require clinicians to have a complete understanding of indications, complications, and clinical applications. Although tracheostomy tubes are used to a lesser extent than endotracheal tubes in most ICUs, their use typically requires additional education and training because of the complexity and diversity of available tubes, care of surgical site, and other related nursing care issues. The purpose of this article is to provide a review of current practice trends for those caring for the adult patient who has a tracheostomy tube. The first section of the article is an overview of the indications, surgical techniques, and types of tubes used in the critical care setting. The second section examines specific aspects of nursing care of patients who have tracheostomy tubes.

Chronic obstructive pulmonary disease in geriatric critical care

COPD is a progressive disorder that is punctuated in its later stages with acute exacerbations that present a risk for respiratory failure. COPD has a disproportionate impact on older patients. In the ICU, therapy is directed toward unloading fatigued respiratory muscles, treating airway infection, and prescribing bronchodilatory drugs. Most patients survive hospitalization in the ICU for an episode of respiratory failure. The severity of the underlying lung disease, however, underlies the poor outcomes of patients in terms of postdischarge survival and quality of life.

Tracheotomy: timing and techniques

PURPOSE OF REVIEW

Until the past 40 years, the timing of tracheotomy was of little concern. It was an emergency procedure developed for the relief of airway obstruction. Following the development of positive pressure ventilation, tracheotomy became an elective procedure. Today, the optimal time for tracheotomy is a subject of dispute and continued investigation. As this operation has become one of the most commonly performed procedures in the intensive care unit, nonoperative dilational methods have gained acceptability. The purpose of this review is to analyze the recent literature and draw insight into the timing and technique of the current state of tracheotomy.

RECENT FINDINGS

Individualized assessment of patients should guide the timing of tracheotomy, with a preference toward early tracheotomy. Percutaneous dilational tracheotomy (PDT) can be performed with equivalent safety to open tracheotomy. Bedside open tracheotomy negates the cost-saving benefits of PDT. Endoscopic guidance in PDT decreases complications with needle placement and posterior tracheal wall injury. Major complications of PDT usually are associated with displacement of the tracheotomy tube.

SUMMARY

Tracheotomy indications have remained unchanged, but the timing of the procedure has advanced to individualized assessment with a predilection for earlier tracheotomy. The traditional operative technique is a much safer procedure today. Percutaneous dilational tracheotomy has become an acceptable alternative with proper patient selection. A multidisciplinary team with a surgeon provides the best care for the patient undergoing percutaneous tracheotomy.
