Tracheotomy in infants and young children: the changing perspective 1970-1985

Tracheostomy practices in children on mechanical ventilation: a systematic review and meta-analysis

OBJECTIVE

To evaluate current practices of tracheostomy in children regarding the ideal timing of tracheostomy placement, complications, indications, mortality, and success in decannulation.

SOURCE OF DATA

The authors searched PubMed, Embase, Cochrane Library, Google Scholar, and complemented by manual search. The guidelines of PRISMA and MOOSE were applied. The quality of the included studies was evaluated with the Newcastle-Ottawa Scale. Information extracted included patients' characteristics, outcomes, time to tracheostomy, and associated complications. Odds ratios (ORs) with 95% CIs were computed using the Mantel-Haenszel method.

SYNTHESIS OF DATA

Sixty-six articles were included in the qualitative analysis, and 8 were included in the meta-analysis about timing for tracheostomy placement. The risk ratio for "death in hospital outcome" did not show any benefit from performing a tracheostomy before or after 14 days of mechanical ventilation (p = 0.49). The early tracheostomy before 14 days had a great impact on the days of mechanical ventilation (-26 days in mean difference, p < 0.00001). The authors also found a great reduction in hospital length of stay (-31.4 days, p < 0.008). For the days in PICU, the mean reduction was of 14.7 days (p < 0.007).

CONCLUSIONS

The meta-analysis suggests that tracheostomy performed in the first 14 days of ventilation can reduce the time spent on the ventilator, and the length of stay in the hospital, with no effect on mortality. The decision to perform a tracheostomy early or late may be more dependent on the baseline disease than on the time spent on ventilation .

Factors affecting tracheostomy in critically ill paediatric patients in Japan: a data-based analysis

BACKGROUND

There has been an increasing number of children surviving with high medical needs, for whom tracheostomy and/or home ventilation is part of their chronic disease management. The purpose of this study was to describe the indications, epidemiology, frequency, and associated factors for tracheostomy in critically ill paediatric patients using the data available in the Japanese Registry of Paediatric Acute Care (JaRPAC).

METHODS

This multicentre epidemiologic study collected data concerning paediatric tracheostomy from the JaRPAC database. Patients were divided into two groups: those with or without tracheostomies when they were discharged from the Intensive Care Unit (ICU) or Paediatric Intensive Care Unit (PICU). Consecutive patients aged ≤16 years who did not undergo tracheostomy when admitted to ICU or PICU between April 2014 and March 2017 were included.

RESULTS

A total of 23 hospitals participated, involving 6199 paediatric patients registered in the JaRPAC database during the study period. Of the registered paediatric patients, 5769 (95%) patients were admitted to the ICUs or PICUs without tracheostomies. Among the patients, 181 patients (3.1%) had undergone tracheostomies. There were significant differences in chronic conditions (134, 74.0% versus 3096, 55.4%, p <  0.01), chromosomal anomalies (19, 10.5% versus 326, 5.8%, p <  0.01), urgent admission (151, 83.4% versus 3093, 55.4%, p <  0.01). More tracheostomies were performed on patients who were admitted for respiratory failure (61, 33.7% versus 926, 16.1%, p <  0.01) and for post-cardiac pulmonary arrest (CPA) resuscitation (40, 22.1% versus 71, 1.1%, p <  0.01).

CONCLUSIONS

This is the first report to use a large-scale registry of critically ill paediatric patients in Japan to describe the interrelated factors of tracheostomies. Chronic conditions (especially for neuromuscular disease), chromosomal anomaly, admission due to respiratory failure, or treatment for post-CPA resuscitation all had the possibility to be risk factors for tracheostomy.

Mortality and respiratory support in X-linked myotubular myopathy: a RECENSUS retrospective analysis

PURPOSE

Individuals with X-linked myotubular myopathy (XLMTM) who survive infancy require extensive supportive care, including ventilator assistance, wheelchairs and feeding tubes. Half die before 18 months of age. We explored respiratory support and associated mortality risk in RECENSUS, particularly among patients ≤5 years old who received respiratory support at birth; this subgroup closely matches patients in the ASPIRO trial of gene therapy for XLMTM.

DESIGN

RECENSUS is an international, retrospective study of patients with XLMTM. Descriptive and time-to-event analyses examined survival on the basis of age, respiratory support, tracheostomy use, predicted mutational effects and life-sustaining care.

RESULTS

Outcomes for 145 patients were evaluated. Among 126 patients with respiratory support at birth, mortality was 47% overall and 59% among those ≤5 years old. Median survival time was shorter for patients ≤5 years old than for those >5 years old (2.2 years (IQR 0.7-5.6) vs 30.2 years (IQR 19.4-30.2)). The most common cause of death was respiratory failure (66.7%). Median survival time was longer for patients with a tracheostomy than for those without (22.8 years (IQR 8.7-30.2) vs 1.8 years (IQR 0.2-not estimable)). The proportion of patients living without a tracheostomy was 50% at age 6 months and 28% at age 2 years. Median survival time was longer with provision of life-sustaining care than without (19.4 years (IQR 3.1-not estimable) vs 0.2 years (IQR 0.1-2.1)).

CONCLUSIONS

High mortality, principally due to respiratory failure, among patients with XLMTM ≤5 years old despite respiratory support underscores the need for early diagnosis, informed decision-making and disease-modifying therapies.

Determinants of successful tracheostomy decannulation in children: a multicentric cohort study

BACKGROUND

Determining prognostic factors for the probability of tracheostomy decannulation is key to an adequate therapeutic plan.

METHODS

A retrospective cohort study of 160 paediatric patients undergoing tracheostomy was conducted. Associations between different parameters and eventual tracheostomy decannulation were assessed.

RESULTS

Mean follow-up duration was 27.8 months (interquartile range = 25.5-30.2 months). Median age at tracheostomy was 6.96 months (interquartile range = 3.37-29.42 months), with median tracheostomy maintenance of 14.5 months (interquartile range = 3.7-21.5 months). The overall tracheostomy decannulation rate was 22.5 per cent. Factors associated with a higher probability of tracheostomy decannulation included age at tracheostomy (hazard ratio = 1.11, 95 per cent confidence interval = 1.03-1.18) and post-intubation laryngitis as an indication for tracheostomy (hazard ratio = 2.25, 95 per cent confidence interval = 1.09-4.62). Neurological (hazard ratio = 0.30, 95 per cent confidence interval = 0.12-0.80) and pulmonary (hazard ratio = 0.41, 95 per cent confidence interval = 0.18-0.91) co-morbidities were negatively associated with tracheostomy decannulation. The probability of tracheostomy decannulation decreased significantly with increasing numbers of co-morbidities (p < 0.001).

CONCLUSION

Age, post-intubation laryngitis, and number and type of co-morbidities influence tracheostomy decannulation rate in the paediatric population.

Neonatal Tracheostomy

Neonatal and infant tracheostomies have been valuable in the care and survival of children over the past century. With the implementation of neonatal and pediatric intensive care units, more infants are surviving conditions that were considered fatal. Neonatal tracheostomy plays a vital role in many of these conditions, with significant implications and association with overall mortality, morbidity, and developmental outcomes. Although the technique has not changed much, there have been significant evolutions in indications, survival, complications, and technological advances. Improved outcomes research to decrease the high associated morbidities is needed.

Changing Indications for Pediatric Tracheotomy: An Urban Indian Study

To review the changing indications, decannulation rates, complications and mortality in pediatric tracheotomies. Medical records of children who underwent primary or revision tracheotomy from April 2003 to December 2015 were retrospectively analyzed. Patient characteristics including age, sex, preoperative diagnosis and indications for tracheotomy. The complications, mortality and decannulation rates for the tracheotomies were studied. There were 101 patients who underwent tracheotomy over a period of 13 years. Out of these, complete data was available for 99 patients. There were 61 males and 38 females and the age of children who underwent tracheotomy on an average ranged from 2 months to 16 years. The indications were divided into five categories: airway obstruction, cardiopulmonary, craniofacial, neurological, and trauma. Out of the 99 patients, 92 patients underwent an elective tracheotomy while only 7 patients underwent an emergency tracheotomy. Fifty-eight patients could be successfully decannulated. 13 patients in our study died during the course of treatment, however, none of the deaths could be directly attributed to the tracheotomy. Three patients developed peristomal granulations requiring intervention, 1 patient had a severe stomal infection, and one patient had a tracheocutaneous fistula requiring surgical closure. Over the last few decades, widespread use of vaccinations and improved pediatric and neonatal intensive care has revolutionized child healthcare in developing countries like ours. This impact is reflected in our finding that neurological impairment has displaced obstructive airway (of infective etiology) as the most common indication for pediatric tracheotomy in the present era.

Tracheostomy in Children

Tracheostomy is more hazardous in children than in adults, and carries special risks in the very young. The past 20 years have seen a large shift in the age distribution of tracheostomy. Whereas formerly the operation was done largely for management of epiglottitis and laryngotracheobronchitis, today the prime indication is subglottic stenosis in infants consequent upon intubation for respiratory distress syndrome and prematurity. We have reviewed experience with 57 tracheostomies in 56 children under 12 years old managed from a university hospital.

All operations were done as elective procedures, in standard fashion, by otolaryngologists. Forty (70%) were in children under 1 year old, the indications being upper airways obstruction (41), failed extubation (11), and long-term assisted ventilation (5). Subglottic stenosis was the commonest cause of obstruction (21 operations). In 91.4 accumulated years with a tracheostomy there were 11 complications related to tracheostomy, one of which (a blocked tube) was fatal. Thirty-nine children were decannulated, the mean duration of cannulation being 21 months.

In this series we suggest that the low morbidity and mortality rates were due to management by otolaryngologists; to postoperative intensive care; and, for the majority cared for at home, to careful education of parents and visits by specialist nurses.

Revisits after pediatric tracheotomy: Airway concerns result in returns

OBJECTIVES

Children undergoing tracheotomy represent a medically vulnerable patient population, and understanding the reasons for revisiting the hospital setting following tracheotomy is critical for improving the quality of care for these patients. This study aims to investigate the incidence and characteristics of revisits following pediatric tracheotomy.

METHODS

Cross-sectional, population-based study using state databases. The State Inpatient Databases and State Emergency Department Databases for California, Florida, Iowa and New York 2010-11 were linked and examined for cases of pediatric tracheotomy (patients < 18.0 years) and corresponding subsequent 30-day post-discharge revisits. Demographic and descriptive data were analyzed determining the revisit rate, revisit diagnoses, procedures, and discharge dispositions.

RESULTS

2,248 pediatric tracheotomy cases were extracted (60.8% male, mean age 8.3 years). There were 373 inpatient or emergency department revisits (30-day revisit rate, 16.6%), of which 34.3% occurred within 48 h after discharge. Of these, 59.2% were inpatient readmissions. There were ≤10 deaths during these revisits (30-day revisit mortality rate, ≤2.7%). The most common primary revisit diagnoses were "fitting of prosthesis and adjustment of devices" (25.7%, likely representing adjustment/replacement of the tracheotomy tube), respiratory failure (11.0%), intracranial injury (5.4%), pneumonia (4.0%), "other upper respiratory disease" (3.8%), and "complications of surgical procedures or medical care" (3.8%). The most common revisit procedures were endotracheal intubation (11.4%), mechanical ventilation (8.8%), and replacement of tracheostomy tube (≤2.7%). Children discharged to a skilled care facility (47.1%) were more likely than those discharged to home (52.9%) to have a revisit (23.3% versus 12.0%, respectively; p < 0.001).

CONCLUSIONS

Children undergoing tracheotomy have a substantial 30-day revisit rate, most notably during the first 48 h after discharge, often involving tracheotomy tube or pulmonary complications. Improvements in discharge planning should target prevention of these complications.

Postoperative management of pediatric tracheostomy: Results of a nationwide survey

OBJECTIVE: A survey was undertaken to document the postoperative care of pediatric tracheostomies by otolaryngologists.

STUDY DESIGN: This study represents the results of a national survey of 564 otolaryngologists covering a broad scope of postoperative pediatric tracheostomy issues considered for patients younger than 2 years and patients older than 5 years.

RESULTS: Of the surveys sent, 134 responses were received, portraying a certain standard management scheme that seems to be used by most respondents.

CONCLUSIONS: Very little difference was seen in respondents' management of patients younger than 2 years of age as compared with those who are older than 5 years. Furthermore, agreement between actual practice and published recommendations seems to vary with some management issues. The results of this study provide a means by which otolaryngologists may familiarize themselves with national trends in the postoperative management of pediatric tracheostomies.

Indications of pediatric tracheostomy over the last 30 years: Has anything changed?

IMPORTANCE

Recent reports have shown that the indications for pediatric tracheostomy have evolved over time.

OBJECTIVE

To review the indications for pediatric tracheostomy over the last 30 years.

DESIGN

Retrospective chart review.

SETTING

Tertiary referral children's hospital.

PARTICIPANTS

Patients who underwent tracheostomy.

INTERVENTION

Surgical tracheostomy placement.

MAIN OUTCOMES AND MEASURES

Medical records for patients who underwent surgical tracheostomy over the 30-year study period (1984-2014) were reviewed. Patient characteristics including age, gender, birth-weight, gestational age and death were collected and compared with the primary indication for tracheostomy using bivariable analysis.

RESULTS

Five hundred and one patients met inclusion criteria. The most common primary indications for tracheostomy were cardiopulmonary disease (34%) and neurological impairment (32%), followed by airway obstruction (19%), craniofacial (11%), and traumatic injury (4%). Over the last five years (2010-14) cardiopulmonary disease became the most common indication for tracheostomy.

CONCLUSIONS

and

RELEVANCE

The indications for pediatric tracheostomy have evolved over the past 30 years. Infectious causes of airway obstruction and tracheostomy have almost disappeared. Tracheostomy is now most commonly performed in very premature patients with cardiopulmonary or neurological impairment who require prolonged ventilator support.

Tracheostomy in childhood: review of the literature on complications and mortality over the last three decades

INTRODUCTION

Tracheostomy is a procedure with unique characteristics when used on pediatric patients due to the greater technical difficulty and higher morbidity and mortality rates relative to the procedure in adults. In recent decades, there have been significant changes in the medical care available to children, particularly for those who need intensive care. Surgical conditions have also improved, and there has been an advent of new equipment and medications. These advances have brought changes to both tracheostomy indications and tracheostomy complications.

OBJECTIVE

To perform a review of the articles published over the last three decades on the complications and mortality associated with tracheostomies in children.

METHODS

Articles were selected from the Cochrane, Latin American and Caribbean Health Sciences Literature, SciELO, National Library of Medicine (Medline Plus), and PubMed online databases. The articles selected had been published between January 1985 and December 2014, and the data was compared using the Chi-square test.

RESULTS

A total of 3797 articles were chosen, 47 of which were used as the basis for this review. When the three decades were evaluated as a whole, an increase in tracheostomies in male children under one year of age was found. The most common complications during the period analyzed in descending order of frequency were granuloma, infection, and obstruction of the cannula, accidental decannulation, and post-decannulation tracheocutaneous fistula. In the second and third decades of the review, granulomas represented the most common complication; in the first decade of the review, pneumothoraces were the most common. Mortality associated with tracheostomy ranged from 0% to 5.9%, while overall mortality ranged from 2.2% to 59%. In addition, the review included four studies on premature and/or very underweight infants who had undergone tracheostomies; the studies reported evidence of higher mortality in this age group to be largely associated with underlying diseases.

CONCLUSION

Improved surgical techniques and intensive care, the creation of new medications, and vaccines have all redefined the main complications and the mortality rates of tracheostomy in children. It is a safe procedure that increases chances of survival in those who require the prolonged use of mechanical ventilation.

Indications, Hospital Course, and Complexity of Patients Undergoing Tracheostomy at a Tertiary Care Pediatric Hospital

OBJECTIVE

The purpose of this study was to review inpatients undergoing tracheostomies at a tertiary care pediatric hospital in a 24-month period and to identify the indications, comorbidities, hospital course, patient complexity, and predischarge planning for tracheostomy care. The goal was to analyze these factors to highlight potential areas for improvement.

STUDY DESIGN

Case series with chart review.

SETTING

Tertiary care pediatric hospital.

SUBJECTS

Ninety-five inpatients at Boston Children's Hospital requiring a primary or revision tracheostomy during the 24-month period encompassing 2010 to 2011.

METHODS

Inpatients undergoing tracheostomy during the study period were identified using 2 different databases: the Boston Children's Hospital Department of Otolaryngology and Communication Enhancement database and institution-specific information from the Child Health Corporation of America's Pediatric Health Information System (PHIS). We extracted the specified metrics from the inpatient charts.

RESULTS

Patients undergoing tracheostomy are complex, with an average of 3.4 comorbidities and 13.6 services involved in their care. The tracheostomy was mentioned in 97.9% of physician and 69.5% of nurse discharge notes, and 42.5% of physician discharge notes contained a plan or appointment for follow-up. Of the patients, 33.7% were discharged home (27.3% of the nonanatomic group and 52.4% of the anatomic group). Overall, 8.4% of tracheostomy patients died before discharge.

CONCLUSION

The complexity of pediatric tracheostomy patients presents challenges and opportunities for optimizing quality of care for these children. Future directions include the introduction and assessment of multidisciplinary tracheostomy care teams, tracheostomy nurse specialists, and tracheostomy care plans in the pediatric setting.

Pediatric tracheotomy: indications and decannulation outcomes

OBJECTIVES/HYPOTHESIS

The objective of this study was to determine if there are differences in decannulation rates and duration of cannulation between pediatric patients undergoing tracheotomy for different indications.

STUDY DESIGN

Retrospective chart review.

METHODS

Medical records for pediatric patients (age 0-18 years) undergoing tracheotomy between January 1, 2003, and May 31, 2012, were retrospectively reviewed. Patients were assigned an indication for tracheotomy from five categories: neurological, cardiopulmonary, upper airway obstruction, craniofacial anomalies, and maxillofacial/laryngotracheal trauma.

RESULTS

Initial chart review identified 124 patients, 113 for whom complete data was available. Of these patients, the indications for tracheotomy were cardiopulmonary disease in 24 (21.2%), craniofacial anomalies in 12 (10.6%), neurological impairment in 44 (38.9%), traumatic injury in 11 (9.7%), and upper airway obstruction in 22 (19.5%). The time to decannulation was shorter for trauma patients compared to cardiopulmonary (P = 0.044) and neurological patients (P = 0.001). A total of 32 (31.9%) patients were decannulated during the study period, with a higher rate in trauma patients (72.7%) and a lower rate in those with upper airway obstruction (36.4%) than would be expected under homogeneity. Of the 32 patients who were decannulated, 11 (30.6%) were decannulated during the same hospitalization in which the tracheotomy was performed.

CONCLUSION

This study demonstrates a difference in overall decannulation rates and a shorter time to decannulation in children undergoing tracheotomy for maxillofacial and laryngotracheal trauma compared to cardiopulmonary and neurological indications.

Pediatric tracheotomy: are the indications changing?

OBJECTIVE

The most common indications for tracheotomy in pediatric patients include upper airway obstruction, prolonged ventilator dependence, and hypotonia secondary to neurologic impairment. In this study we review the indications for tracheotomy within our patient population over the last 11 years.

METHODS

We conducted a retrospective chart review of consecutive patients undergoing tracheotomy at a tertiary care pediatric hospital from January 2000 to April 2011. We evaluated patient age, sex, pre-operative and post-operative diagnosis, and direct laryngoscopic and bronchoscopic findings. Patients were divided into six groups based on their indication for tracheotomy. In order to assess changing indications for tracheotomy over time, we compared an early (2000-2005) and a late (2006-2011) patient group.

RESULTS

We had complete data available on 158/165 patients (95.8%) who underwent tracheotomy from 2000 to 2011. There was no significant difference in mean age between the early and late groups (4.73 ± 6.0 years vs. 3.6 ± 5.5 years, p=0.26). There was a change in the most common indication for tracheotomy between the early and late groups, with upper airway obstruction becoming more common in the late group and significantly fewer patients undergoing tracheotomy for prolonged ventilation in the late group (33/76 (43%) vs. 23/82 (28%), p=0.05). More patients underwent bronchoscopy at the time of tracheotomy in the late group (52/82 (63%) vs. 28/76 (37%), p=<0.01).

CONCLUSION

A review of our pediatric tracheotomy experience demonstrated a change in the most common indication for tracheotomy between 2000 and 2011. In our patient population, there was a significant decline in the number of tracheotomies performed for prolonged intubation and an increasing number of patients who required tracheotomy for upper airway obstruction.

S-shaped tracheostoma in pediatric tracheostomy using three-dimensional sigma-plasty--a novel technique to possibly reduce procedure related complications

OBJECTIVES

We have designed a technique of tracheostomy in pediatric patients with S-shaped incision on the tracheal wall which we think, provides a larger cross-sectional area of stoma and facilitates easier insertion of tracheostomy tube and thus helped in reducing early and late complications associated with it in our series.

TECHNIQUE

The trachea was exposed in midline by a vertical skin incision. In order to make S-shaped tracheostoma, second tracheal ring was identified. The conventional vertical incision was made in second tracheal ring and then extended at both its ends laterally in the inter-cartilaginous space parallel to the tracheal cartilage in the opposite direction to make the incision S-shaped. The trachea was dilated with tracheal dilator and appropriate size of tracheostomy tube was then placed into the trachea.

RESULTS

S-shaped tracheostomy was performed in 40 children with mean age of 6.36 years (age range is 2-12) required for airway maintenance or prolonged ventilatory support. The incidence of early complications was quite less in our patients (ranged from 0 to 5%). There was no incidence of excessive intra-operative bleeding or injury to surrounding structures causing subcutaneous emphysema or vocal cord palsy. One patient developing pneumothorax after the procedure was managed conservatively. There was no incidence of tracheo-esophageal fistula, suprastomal collapse or difficulty in decannulation on 9 months of follow up related to our technique. However, one of the patients developed early trachietis and cutaneous peristomal granulomas and 2 patients developed late trachietis which was treated conservatively.

CONCLUSION

S-shaped tracheoplasty, a new pediatric tracheotomy technique has resulted in a quantifiable reduction in the risk of the early and late complications in our series. Hence, we feel that this new technique is a better alternative to existing methods but larger randomized controlled studies are required before universal adoption of this technique.

Tracheostomy in young patients: indications and long-term outcome

Diagnostic and treatment modalities have changed substantially over the past years in the field of pediatrics and neonatal medicine. As a result, the indications and outcome after tracheostomy in young patients have evolved. The aim of this study is to present our experience with pediatric tracheostomies and provide an up-to-date review of the literature with special focus on current trends. The complete medical records of 85 children and adolescents (up to age 18) which underwent tracheostomy from January 1990 until March 2008 were reviewed. Telephone interviews were conducted to evaluate the childrens further clinical course. The indications for tracheostomy were upper airway obstruction (27%), craniofacial syndromes (3.5%), long-term mechanical ventilation (22.3%), neurological deficit (25.9%), trauma and sequelae (16.5%) and bilateral vocal cord paralysis (4.7%). The average age of patients at the time of tracheostomy was 4.7 years (range, 2 days-18 years) but there were significant differences between the six indication groups. Children under the age of 7 years comprised 72.9% of all patients. The mean cannulation time was 21.6 months; 50.6% of the patients could be successfully decannulated. Life-threatening complications occurred in 6 patients (7%). The total mortality rate was 18.8%; the tracheostomy related mortality rate was 0%. In the past 30 years, short-term tracheostomy was commonly performed for infectious causes such as epiglottitis. Nowadays, the majority of patients are very young children with severe and chronic diseases. This fact accounts for the relatively low decannulation rates, long cannulation times and high mortality. The tracheostomy related mortality on the other hand, is comparatively low.

Surgical management of severe suprastomal cricotracheal collapse complicating pediatric tracheostomy

OBJECTIVE

Suprastomal tracheal collapse may interfere with decannulation in tracheostomized patients. The purposes of the study are to evaluate the role of tracheotomy technique in the ethiology of suprastomal cricotracheal collapse and to report our results in the treatment of this complication.

METHODS

A retrospective review of children showing severe suprastomal collapse during the period 1990-2007, in a tertiary care children's hospital, was performed. Medical records were assessed for the following data: sex, age, original indication for tracheotomy, surgical technique, endoscopic findings, type of surgical correction, complications, result, and follow-up.

RESULTS

Fourteen patients were included in the study, nine girls and five boys. Average age at tracheotomy was 17 months (range: 21 days-8 years), and prolonged ventilatory support was the most common indication (57%). Horizontal H-type tracheotomy was the most frequent technique in patients with suprastomal collapse (n=9), whereas only one patient with a vertical tracheotomy showed this complication (p<0.05). In every case bronchoscopy disclosed a suprastomal tracheal obstruction of at least 50% of the lumen. Mean age at surgical decannulation was 38 months (range: 12-147 months). Two surgical techniques have been used in the treatment of suprastomal collapse: anterior cricotracheal suspension (n=13) and reconstruction with autologous cartilage graft (n=1). All the patients were successfully decannulated although in one case two procedures were required. No recurrence has been observed during long-term follow-up (mean: 8.6 years).

CONCLUSIONS

Endoscopical examination is essential for the diagnosis of suprastomal collapse and to rule out other causes of decannulation failure. In our experience, the tracheotomy technique seems to have an ethiologic role, and anterior cricotracheal suspension is a simple and effective procedure in the treatment of this tracheostomy related complication.

Current trends in paediatric tracheostomies

OBJECTIVE

In the 1970s, the most common indication for tracheostomy in children was acute inflammatory airway obstruction. Modern neonatal intensive care units have turned long-term intubation into an alternative to tracheostomy. Long-term intubation itself has become the most important indication for tracheostomy combined with subglottic stenosis.

METHODS

Retrospective analysis in a tertiary referral center. A total of 38 patients who underwent tracheostomy for respiratory failure and upper airway obstruction from 1 November 1998 to 30 November 2004.

RESULTS

Total complication rate was 42.1%. In children under 1 year of age the complication rate was 47.4%, in children over 1 year the complication rate was 26.3%. Decannulation was attempted in 12 patients with a cannulation time of 22 months.

CONCLUSIONS

Long-term intubation and its sequelae have now become one of the most important indication for tracheostomy. The change of indication has also entailed a decrease of the average age of children who require tracheostomy. A longer period before decannulation and a lower average age have changed the complication rate of tracheostomy in paediatric patients.

Indications for tracheostomy in children

Vaccination programs, improvements in material engineering and anaesthetic skills have dramatically reduced the number of emergency tracheostomies performed for acute upper airway obstruction. Today, the indication to tracheotomise a child is generally ruled by the anticipation of long-term (cardio)respiratory compromise due to chronic ventilatory or, more rarely, cardiac insufficiency, or by the presence of a fixed upper airway obstruction that is unlikely to resolve for a significant period of time. As many of the younger candidates for tracheostomy have complex medical conditions, the indication for this intervention is often complicated by ethical, funding and socio-economic concerns that necessitate a multidisciplinary approach. Unfortunately, these considerations are frequently not made until the first catastrophe has occurred, even in those patients in whom imminent cardiorespiratory failure has been foreseeable. Non-invasive ventilation via a face mask and newer developments such as the in-exsufflator device have gained importance as an alternative to tracheostomy in selected patients.

Tracheotomy in children: evolution in indications

OBJECTIVES

To evaluate the evolution of indications for tracheostomy in children.

METHODS

A retrospective review of 46 children undergoing tracheostomy between 1996 and 2001.

RESULTS

The indications for tracheostomy were classified in two groups:(1) prolonged ventilator dependence (57%), (2) upper airway obstructions (43%). The average age of the tracheostomy was 3 years and 8 months. This was higher in the first group (5.5 years). Decannulation was accomplished in 52%. The indications for tracheostomy were evaluated and were found to decrease in frequency for upper airway obstructions. An increasing indication was for chronic disorders requiring prolonged ventilator dependence. Complications occurred in 50% of children. Overall mortality was 13-2.7% directly related to the tracheostomy.

CONCLUSIONS

Evolving indication has been ventilator dependence. Upper airway obstruction as an indication has diminished in frequency, especially with the concomitant progress of endoscopic techniques.

Outcome of patients requiring tracheostomy in a pediatric intensive care unit

BACKGROUND

Although tracheostomy is a commonly performed procedure, there is a lack of studies in the pediatric intensive care unit (PICU) setting that describe its association with patient outcome and especially hospital mortality. Our goal was to evaluate the outcome of patients receiving a tracheostomy, while on mechanical ventilation (MV), in a PICU.

METHODS

Records of 260 children were reviewed retrospectively regarding PICU mortality, PICU length of stay (PICU LOS), duration of MV and a cost indicator (weighted hospital days; WHD).

RESULTS

Nineteen patients received tracheostomy (7.3%). The mortality of patients submitted to tracheostomy in the longer term was significantly higher compared to patients who were not (52.6%vs. 27.6%; P = 0.04) despite having a significantly lower severity of illness at admission (Pediatric Risk of Mortality score--PRISM) (10.9 vs. 13.7; P < 0.001). The mortality of patients without tracheostomy, however, was significantly higher within 30 days (24.8%vs. 5.2%, P < 0.001). Tracheostomized patients had significantly higher mean PICU LOS (68 days vs. 8 days; P < 0.001), duration of MV (62 days vs. 4 days; P < 0.001) and higher WHD (171.5 vs. 21.5; P < 0.001).

CONCLUSION

Contrary to findings in critically ill adult patients, ventilated children receiving a tracheostomy had less favorable outcomes compared with non-tracheostomized patients. In view of the greater use of resources, further studies are needed to confirm and to identify the subgroups of mechanically ventilated patients who will benefit most from this procedure.

"Starplasty" prevents tracheotomy complications in infants

OBJECTIVE

The average age of children undergoing tracheotomy has declined over the years and the indications for tracheotomy have changed from acute airway obstruction due to infection, to treatment of chronically ill children. Tracheotomy-related complication rates are more numerous in younger children and in certain cases have proved to be fatal. A variety of operative techniques have been advocated for reducing the rate of tracheotomy-related morbidity and mortality. This manuscript reports on our experience with a new technique--starplasty tracheotomy (SPT)--and assesses the value of this procedure in preventing tracheotomy-related complications in infants (under 6 months old), in whom complications are more frequent and more dangerous.

METHODS

Children less than 6 months old who underwent tracheotomy in the Department of Otolaryngology/Head and Neck Surgery, Hadassah University Hospital, Jerusalem, between the years 1999 and 2003 were studied. They were divided into two groups according to the surgical technique preferred and performed by the senior surgeon on call. Children in group 1 underwent tracheotomy by means of a regular technique and children in group 2 underwent SPT. All events related to the tracheotomy were recorded and a comparison was made between the two groups.

RESULTS

Eleven of a total of 26 pediatric tracheotomy patients were less than 6 months old. Five underwent regular tracheotomy (RT) and six underwent SPT. Three complications were encountered in the RT group and none in the SPT group. Accidental decannulation and failure to re-insert the cannula resulted in severe hypoxemic brain damage in one patient with RT. No tracheotomy-related deaths occurred.

CONCLUSION

Our experience supports the existing data regarding the superiority of SPT over RT in preventing dangerous tracheotomy-related complications in infants. We, therefore, recommend performing SPT in all infants undergoing tracheotomy, even at the price of having to perform surgical closure of TCF after decannulation in some cases.

Six cases of children with a benign cervical tumor who required tracheostomy

Cervical tumors sometimes cause airway obstruction. We have treated six children with benign cervical tumors who required tracheostomy. Two cervical and one glossal lymphangiomata treated with local injection of OK432 after creating a tracheostomy were successfully decannulated after the treatment. One patient with a giant cervical lymphangioma needed an EXIT (ex utero intrapartum treatment) procedure. He underwent tracheostomy at 10 months of age after long-term endotracheal intubation, but he died of sepsis and hypoxic brain damage at 18 months. One patient with a subglottic hemangioma treated with steroids finally achieved closure of the tracheostomy at 2 years of age. A 7-year-old girl with a tracheal schwannoma underwent tracheostomy performed a week after admission, but she already had hypoxic brain damage resulting from problems with intubation. Most patients with a lymphangioma or hemangioma in the cervical region have required early tracheostomy before commencing treatment with OK-432 or steroids. If there is any sign of possible airway compromise, then it is vital to perform an early tracheostomy, even for benign tumors.

Children with a tracheostomy: experience of their carers in school

OBJECTIVE

Tracheostomies in children are increasingly performed for chronic medical conditions. There are no published studies reporting the experience of children with a tracheostomy in school. Such information would be valuable in planning the care and education of these children. The aims of this study were to identify those children with a tracheostomy in Nottinghamshire schools and determine the support they were receiving.

DESIGN, SETTING AND PARTICIPANTS

Questionnaire survey to families and school carers of 11 children with a tracheostomy.

RESULTS

All children of school age were in full-time education (five mainstream, five special schools). One preschool child attended a Family Centre. Four had problems finding suitable carers, delaying return to school in three. Four parents were dissatisfied with aspects of the child's experience at school: two felt the teaching staff were unsupportive, one was unhappy with the care of the tracheostomy, and one had problems funding a carer. Ten out of 11 school carers were satisfied with their training; 10 would have liked regular update sessions. The amount of care required varied. Those with complex medical problems in a special school setting needed frequent care, and one had required admission to hospital from school. One child had time off school because of lack of carer availability. Those who were severely disabled had less time off school for ill health after the tracheostomy than before the tracheostomy.

CONCLUSION

Children with tracheostomies can successfully and safely achieve full-time education in both mainstream and special schools. A dedicated multidisciplinary team, including input from the parents, is essential to achieve this goal. Regular revision of skills and information sessions for the teaching staff would be beneficial.

Surgical airway management in Pierre Robin sequence: is there a role for tongue-lip adhesion?

OBJECTIVE

The purpose of this study was to examine the efficacy of tongue-lip adhesion (TLA) in the management of clinically significant airway obstruction associated with Pierre Robin sequence.

DESIGN

The records of all children admitted to The Children's Hospital of Philadelphia with a diagnosis of Pierre Robin sequence were reviewed. Charts were reviewed for birth data, diagnosis, preoperative airway management methods, and surgical intervention. Records of infants undergoing TLA were analyzed for timing of surgery, operative technique, postoperative complications, length of hospital stay, and treatment outcome.

RESULTS

Over the 28-year period 1971 to 1999, 107 patients (47 boys, 60 girls) meeting the criteria for Pierre Robin sequence were admitted for treatment. Of these, 74 (69.2%) were successfully managed by positioning alone. Surgical management of the airway was performed in the remaining 33 (30.8%) patients, 29 of whom underwent TLA and 4 of whom underwent tracheostomy. Dehiscence of the adhesion occurred in five patients (17.2%), two of whom subsequently required tracheostomy. Within the group of patients who underwent mucosal adhesion alone, the dehiscence rate was 41.6%. When the adhesion included muscular sutures, however, dehiscence was not observed in any patient. Of the 24 patients in whom primary TLA healed uneventfully, airway obstruction was successfully relieved in 20 (83.3%). Failure of a healed TLA to relieve the airway obstruction resulted in conversion to a tracheostomy in four patients. Six patients who underwent TLA (20.7%) ultimately required a tracheostomy; five of these patients (83.3%) were syndromic. Of patients requiring preoperative intubation, 42.9% ultimately required tracheostomy.

CONCLUSION

TLA successfully relieves airway obstruction that is unresponsive to positioning alone in the majority of patients with Pierre Robin sequence and should therefore play an important role in the management of these infants.

The changing indications for paediatric tracheostomy

OBJECTIVE

To investigate whether the incidence and indications for paediatric tracheostomy in this unit have changed over recent years.

METHODS

All paediatric tracheostomies performed between 1993 and 2001 were identified from our departmental database. The indications for these were ascertained by retrospective case note review.

RESULTS

Over the 9-year period studied 362 tracheostomies were performed, the number increased slightly between the first and second half of the period, with peaks in 1997 and 1999. The commonest indication was prolonged ventilation due to neuromuscular or respiratory problems.

CONCLUSIONS

This large series shows that the increase in frequency of paediatric tracheostomy performed in this unit over the past decade has been due to conditions such as subglottic and tracheal stenosis, respiratory papillomatosis, caustic alkali ingestion and craniofacial syndromes. Conditions in which tracheostomy are now less common are subglottic haemangioma and laryngeal clefts. Prolonged ventilation remains the commonest indication overall.

Indications, complications, and surgical techniques for pediatric tracheostomies--an update

BACKGROUND

With the decrease of life-threatening obstructive upper airway infections and the ongoing improvement of intensive care medicine, the role of tracheostomy in children has been changing considerably, until now. The aim of this study was to establish data regarding indications, complications, and techniques of pediatric tracheostomy, which would reflect the current state of science.

METHODS

The authors analyzed the international literature as well as their own experience with 25 children less than 6 years of age who were operated on between 1980 and 1996.

RESULTS

Literature proved to be very heterogeneous in terms of terminology, patient groups, operation techniques, indications, and complications. Within the past decades, long-term intubation and congenital anomalies of the upper respiratory tract have become increasingly prevalent, whereas inflammatory diseases were less and less an indication for tracheostomy. Endotracheal intubation as an alternative has resulted in less frequent tracheostomies in general. Today, children can be ventilated for months without considerable complications. However, individual, clinical, and fiberoptical controls are necessary. Tracheostomy-related complications have not changed significantly. Fatalities are mostly caused by the underlying disease. The most frequent causes of tracheostomy-related death are cannula obstruction and accidental decannulation. The most frequent early complications are pneumomediastinum, pneumothorax, wound complications, and bleedings. Subsequent complications most often are granulations and tracheal stenosis.

CONCLUSIONS

The authors' research agreed widely with that in the literature. However, no tracheostomy-related death occurred. Possibly, this was because of their operative technique. In the opinion of the authors, establishing a cartilage window facilitates cannula exchange and reduces the risk of a fatal accidental decannulation.

Robin sequence: review of treatment modalities for airway obstruction in 110 cases

OBJECTIVE

The objective of this paper is to assess the treatment protocols used in our institution for the management of airway obstruction among patients with Robin sequence and to suggest a rationale for management based on the findings.

METHOD

A retrospective study of 110 children with Robin sequence seen from 1988 to 1997 at the Chang Gung Memorial Hospital was done. Results of the management in airway obstruction and feeding difficulty were studied.

RESULTS

Prone posturing was effective in the treatment of mild airway obstruction in 82 patients who had noisy breathing sounds. Twenty-eight infants required endotracheal intubation due to severe respiratory distress. Seven received a tongue to lip adhesion (TLA) operation. Three of these patients showed a relief of airway obstruction, while four of them needed a tracheotomy to maintain a patent airway because of wound dehiscence. Two other patients underwent tracheotomy without TLA. All the six patients who received tracheotomy were eventually decannulated. A nasopharyngeal tube was inserted in two other patients, and one of them improved only temporarily. With regards to feeding difficulties, 46 patients needed nasogastric tube feeding, while the rest were aided through the use of a cleft palate bottle and nipple. A gastrostomy was not needed in any of the patients in this series.

CONCLUSION

The morbidity and mortality among Robin sequence patients had been widely decreased through the teamwork of the pediatrician, anesthesiologist, otolaryngologist, dentist, and plastic surgeon. Based on our experience, conservative management was sufficient for those patients with mild airway obstruction, while endotracheal intubation was required for patients with cyanosis, respiratory failure and sleep apnea. Tracheotomy was a better option than TLA for airway management among patients with failed extubation.

Pediatric tracheotomy: is postoperative chest X-ray necessary?

A retrospective study of 101 children who underwent tracheotomy at the Children's Hospital of Pittsburgh from 1993 to 1996 was performed. The following criteria were reviewed in each patient: age, gender, race, prematurity, weight during tracheotomy, presence of preoperative airway support, duration of tracheotomy, nature (emergent versus elective), tracheotomy tube size, reason for tracheotomy, accompanying medical diagnoses, chest x-ray (CXR) findings, surgical service, postoperative symptoms (up to 3 days), and operative mortality rate. Of these criteria, our results show that CXR-screenable complications occurred in patients who underwent emergent recannulation, as well as those who exhibited ventilatory distress (oxygen saturation level of <90%) and specific changes in postoperative symptoms. Pneumothorax developed after tracheotomy in 3 of the 101 patients; each had one of these risk factors. We conclude that CXR of all pediatric patients after tracheotomy may be unnecessary with the use of flexible endoscopy and screening restrictions that are both health-conscious and cost-effective.

Is tracheotomy decannulation possible in oxygen-dependent children?

OBJECTIVE

The goal was to determine whether decannulation can be safely achieved in children with persistent oxygen requirements.

DESIGN

The study was a prospective evaluation of 12 oxygen-dependent children at a tertiary care academic children's medical center.

METHODS

Twelve tracheotomy-dependent children with persistent oxygen requirements were evaluated for decannulation. Patients requiring more than 35% FiO(2) were not considered. Direct laryngoscopy and bronchoscopy were performed in all patients. Two required single-stage laryngotracheoplasty to correct subglottic stenosis, 1 required tracheal resection, and 7 required removal of suprastomal granulation tissue. Oxygen was administered after decannulation through a nasal cannula.

RESULTS

Decannulation was successful in 92% (11 of 12) of patients. At final follow-up, oxygen requirements decreased in 58% of patients after decannulation.

CONCLUSIONS

Decannulation can be successful in children who remain oxygen dependent; conversion to a more physiologic airway may be an adjunct to reducing or eliminating their oxygen demand.

Pediatric tracheotomies: changing indications and outcomes

OBJECTIVE/HYPOTHESIS

To study the outcomes and complications associated with pediatric tracheotomy, as well as the changing trend in indications and outcomes since 1970.

STUDY DESIGN

Retrospective chart review at a major tertiary care children's hospital.

METHODS

On children who underwent tracheotomy at Children's Hospital of the King's Daughters (Norfolk, VA) between 1988 and 1998, inpatient and outpatient records were reviewed. Of 218 tracheotomies, sufficient data were available on 204. Indications for tracheotomy were placed into the following six groups: craniofacial abnormalities (13%), upper airway obstruction (19%), prolonged intubation (26%), neurological impairment (27%), trauma (7%), and vocal fold paralysis (7%).

RESULTS

The average age at tracheotomy was 3.2 +/- 0.6 years. Although the prolonged intubation group was significantly younger than all others, the neurological impairment and trauma groups were significantly older. Decannulation was accomplished in 41%. Time to decannulation was significantly higher in the neurological impairment and prolonged intubation groups, but was significantly shorter in the craniofacial group. Complications occurred in 44%. Overall mortality was 19%, with a 3.6% tracheotomy-related death rate. Comparison of our series to other published series of pediatric tracheotomies since 1970 shows fewer being performed for airway infections and more for chronic diseases, with a corresponding increase in duration of tracheotomy and decreased decannulation rates.

CONCLUSIONS

Tracheotomy is a procedure performed with relative frequency at tertiary care children's hospitals. While children receiving a tracheotomy have a high overall mortality, deaths are usually related to the underlying disease, not the tracheotomy itself.

Fractured tracheostomy tubes in the tracheobronchial tree of a child

Fractured tracheostomy tube presenting as foreign bodies in the tracheobronchial tree is rare. Only four previous episodes in children have been reported in literature and most of these in developing countries. We report an unusual case of fractured tracheostomy tubes in the tracheobronchial tree of a child and review the literature.

Postoperative management of pediatric tracheostomy: results of a nationwide survey

OBJECTIVE

A survey was undertaken to document the postoperative care of pediatric tracheostomies by otolaryngologists.

STUDY DESIGN

This study represents the results of a national survey of 564 otolaryngologists covering a broad scope of postoperative pediatric tracheostomy issues considered for patients younger than 2 years and patients older than 5 years.

RESULTS

Of the surveys sent, 134 responses were received, portraying a certain standard management scheme that seems to be used by most respondents.

CONCLUSIONS

Very little difference was seen in respondents' management of patients younger than 2 years of age as compared with those who are older than 5 years. Furthermore, agreement between actual practice and published recommendations seems to vary with some management issues. The results of this study provide a means by which otolaryngologists may familiarize themselves with national trends in the postoperative management of pediatric tracheostomies.

Management of congenital laryngeal malformations

Congenital malformations of the larynx are relatively rare but may be life-threatening. The most common causes include laryngomalacia, vocal cord paralysis, and subglottic stenosis. The last 20 years has seen major advances in the field of surgical correction of such anomalies also serving to reduce the number of tracheotomies in children and the inherent dangers they pose. Success rates for the most popular surgical procedures have been favorable. These include supraglottoplasty for cases of severe laryngomalacia, in which relief of respiratory symptoms has been shown to occur in excess of 80% of cases. Complication rate is low, although postoperative death has been reported. Failure usually occurs in patients with concomitant airway abnormalities including pharyngomalacia. Vocal cord lateralization for vocal cord paralysis with airway compromise is achieved by means of arytenoidopexy or arytenoidectomy, using the lateral approach. Arytenoidectomy also can be performed using laryngofissure or endoscopic laser excision. Subglottic stenosis is the 3rd most common congenital anomaly. Anterior or multiple cricoid splitting with cartilage graft interpositioning is usually performed. The success rates for these procedures has been shown to be approximately 90%.

Pediatric tracheostomy: a changing procedure?

In 1982, the experience with tracheostomy at The Children's Hospital of Philadelphia was reported for 1971 through 1980. We have now reviewed 450 cases for the period from 1981 through 1992, and compared the characteristics of these cases with those in the previous review. Long-term follow-up was available on 83% of cases, and the median follow-up was 2.96 years. Patients received a tracheostomy for airway obstruction (38%), chronic ventilation (53%), or multiple indications (9%). The mean duration of tracheotomy (adjusted for death and loss to follow-up) was 2.13 years. The tracheostomy-related mortality was 0.5%, and the nontracheostomy-related mortality was 22%. Nineteen percent of patients had complications in the first postoperative week, and 58% had 1 or more late complications. In comparison with the previous study from our institution, there was a great increase in long-term tracheostomy and a continuing trend away from tracheostomy for short-term airway management. Better monitoring and improvements in parental teaching may have contributed to a decrease in tracheostomy-related mortality.

Paediatric tracheostomy: an analysis of 40 cases

Tracheostomy in the paediatric patient has been associated with significant morbidity and mortality compared to that in the adult. A retrospective analysis was made of 40 patients up to the age of 12 years having tracheostomies. Upper airway obstruction made up the commonest (32 patients, or 80 per cent) indication for paediatric tracheostomy in our series where males slightly outnumbered females. The majority (31 patients, or 77.5 per cent) underwent the operation under general anaesthesia with endotracheal intubation. Thirty-four (85 per cent) patients underwent 'planned' tracheostomies and six (15 per cent) underwent 'crash' procedures. Thirteen (32.5 per cent) patients were under the age of one year when tracheostomies were performed. The maximum duration of tracheostomies was between one week to within a month and after one month to within three months; each containing 11 (27.5 per cent) patients. Sixty-four different surgical procedures were performed on these patients in which laryngoscopy and bronchoscopy were the commonest procedures. Nine (22.5 per cent) had early post-operative and 14 (35 per cent) had late post-operative complications. Among these 40 children with tracheostomies, one (2.5 per cent) died due to a tracheostomy-related cause and 10 (25 per cent) due to the primary disease process itself. Tracheostomies performed to provide access for general anaesthesia for other surgical procedures were associated with a better prognosis.

Management of upper airway obstruction in Pierre Robin sequence

Pierre Robin sequence (PRS) presents in the neonatal period with upper airway obstruction and feeding difficulties. Infants with pronounced micrognathia may fail to thrive because of chronic airway obstruction, or experience severe respiratory distress. This is potentially fatal and surgical intervention in these cases is necessary. We present our series of cases with severe PRS requiring surgical relief of their airway obstruction, and the reasons for preferring tracheostomy over glossopexy.

Arytenoidopexy for bilateral vocal fold paralysis in young children

The purpose of this retrospective study was to describe and evaluate the results of arytenoidopexy performed by the external laterocervical approach in 15 consecutive children presenting bilateral vocal fold paralysis causing life-threatening airway compromise. Mean age at the time of surgery was 20 months and mean follow-up was 42 months. At the end of follow-up all patients were in good health and did not need special care for breathing. No abduction movement has been observed on the opposite vocal fold since arytenoidopexy. One failure subsequently required arytenoidectomy. The findings of this study suggest that arytenoidopexy is an effective surgical treatment for life-threatening bilateral vocal fold paralysis in young children.

The superiorly based flap long-term tracheostomy in pediatric patients

PURPOSE

Tracheostomy is commonly used to provide control of the upper airway in pediatric patients. The traditional approach, which uses a midline vertical incision in the anterior tracheal wall, is associated with relatively high rates of complications when it is used on a long-term basis. Alternative approaches, such as removing tracheal window or creating tracheal flaps, have been avoided in the pediatric patient because of the risk of tracheal stenosis and the potential for the subsequent effect on tracheal growth. The superiorly based flap tracheostomy (SBFT) has greatly reduced these risks in adults and offers better stomal maintenance, safety, and patient acceptance, but it has not been widely evaluated in pediatric patients.

METHODS

We reviewed 21 superiorly based flap tracheostomies performed in children at our institution between 1986 and 1993. Routine follow-up assessments included fixed and flexible laryngotracheoscopy. Average follow-up was 17 months.

RESULTS

The most common indication for performing the SBFT was bilateral vocal cord paralysis. Short-term complications included wound infection and granuloma in 2 patients. Long-term complications were not observed. One patient died from lower respiratory tract causes. Five of the patients were eventually decannulated, and the stoma closed without laryngotracheal stenosis. Morbidity rates were less and mortality was comparable to those of traditional tracheostomy.

CONCLUSION

We conclude that the SBFT is promising a technique for establishing long-term control of the airway in pediatric patients.

A twenty year (1971-1990) review of tracheostomies in a major paediatric hospital

Changing trends in the indications for paediatric tracheostomies, with decreasing numbers of tracheostomies being performed, have been reported in the literature. In a retrospective analysis of the period 1971 to 1990 the experience of tracheostomies in children under the age of 15 at Our Lady's Hospital (Dublin) is reviewed. Only 29 tracheostomies were performed during this time with an increase in numbers (90%) performed during the second 10 year period. The major underlying indication for tracheostomy in both 10 year periods was for the management of an airway problem secondary to congenital abnormalities (65%). In 14 children the operation was performed during the first year of life. However, while 90% of the children were under the age of one in the period 1971-1980 this fell to 26% during 1981-1990. Complications occurred in 41% overall, however, in the under 1 year old group 64% developed complications. There were no deaths as a direct result of the tracheostomy or its complications, but six children died because of the severity of the underlying disease. The average length of time before decannulation was 2.1 years, with decannulation difficulties occurring infrequently (11%).

Outcome of laryngeal paralysis in neonates: a long term retrospective study of 113 cases

Between 1985 and 1990, 113 children were diagnosed as having congenital vocal cord paralysis. Most of them were still being followed up in June 1994. Fifty two had bilateral paralysis, 61 had unilateral paralysis: 41 were on the left side and 20 on the right side. Forty two were idiopathic, 29 were associated with neurologic disorders, six were associated with heart malformations. Fifteen children were born after difficult delivery. Among the newborns with unilateral paralysis that occurred after an abnormal delivery, 73% recovered spontaneously; likewise 70% of the neurologic group and 74% of the idiopathic group recovered spontaneously. The prognosis of bilateral paralysis was worse with only 52% of spontaneous recovery in the neurologic disorders group and the idiopathic group. Seven percent of the children underwent a surgical procedure. They were all decanulated or extubated. In view of our experience the prognosis is poor for bilateral idiopathic laryngeal paralysis or those with neurological context.
