Tracheotomies: a 10-year experience in 319 children

Investigation of the Paediatric Tracheostomy Decannulation: Factors Affecting Outcome

Introduction:

Evidence for factors determining paediatric tracheostomy decannulation vary extensively; therefore, this prospective observational study aimed to investigate these factors.

Materials and Methods:

In total, 67 consecutive paediatric patients (<12 years old) who referred to the Department of Otolaryngology, (Postgraduate Institute Medical Education and Research),(Chandigarh), India, for decannulation were included and evaluated for contributing factors in this study. Parental counselling was performed, and informed consents were obtained from them. The patients underwent detailed work up including X-rays of airway/soft tissue neck (STN) and endoscopic assessment under anaesthesia for evaluating airway patency. Decannulations were attempted post assessment and followed up one month to classify decannulation as success or failure regarding the removal of the tracheostomy tube.

Results:

Totally, 61 patients out of 67 cases were successfully decannulated, whereas six children failed the decannulation. Moreover, the duration of tracheostomy (Pearson’s Chi-square 35.330, P=0.013), indication of tracheostomy (Pearson’s Chi-square 21.211, P=0.000), STN X-Ray (Chi-square 43.249, P=0.000), and bronchoscopic findings (Chi-square 67.000, P=0.000) were significantly associated with the outcome of decannulation. However, decannulation outcome had no significant correlation with various factors, such as the duration of intubation preceding tracheostomy, duration of ventilation, tracheal swabs, and antibiotic therapy.

Conclusion:

The STN X-ray is an independent predictor, and it is recommended for paediatric tracheostomy decannulation. Moreover, bronchoscopic assessment should be performed in children having doubtful infra-stomal airway. Duration of tracheostomy significantly affects decannulation outcome. However, intubation duration preceding tracheostomy and duration of assistive ventilation have no direct effects on the outcome of decannulation. In children, gradual decannulation should be preferred and one month follow up is adequate for deciding decannulation outcome.

Multidisciplinary guidelines for the management of paediatric tracheostomy emergencies

Temporary and permanent tracheostomies are required in children to manage actual or anticipated long-term ventilatory support, to aid secretion management or to manage fixed upper airway obstruction. Tracheostomies may be required from the first few moments of life, with the majority performed in children < 4 years of age. Although similarities with adult tracheostomies are apparent, there are key differences when managing the routine and emergency care of children with tracheostomies. The National Tracheostomy Safety Project identified the need for structured guidelines to aid multidisciplinary clinical decision making during paediatric tracheostomy emergencies. These guidelines describe the development of a bespoke emergency management algorithm and supporting resources. Our aim is to reduce the frequency, nature and severity of paediatric tracheostomy emergencies through preparation and education of staff, parents, carers and patients.

Tracheostomy: Experience at Tertiary Hospital

An attempt was made to find indications of tracheostomy procedure and its complications in the modern era of medicine with refined surgical techniques at a tertiary hospital. A retrospective study of 240 patients, who had undergone tracheostomy, was done during the period from January 2013 to April 2017 at Govt. Medical College Hospital. Various details of all participants such as age and sex of patients, detailed history of the current disease, and detailed information about tracheostomy and complications were recorded. In the present study, the most common indication for tracheostomy was prolonged ventilation due to Organophosphorus poisoning and Snake bite. The complication rate for tracheostomy procedure was 11.5%. The most common complication was tubal occlusion (7.5%) followed by Granulations around stoma (2.5%), Tracheal stenosis (1.25%), tracheoesophageal fistula (0.4%). No death was occurred during the tracheostomy procedure. The morbidity and mortality due to tracheostomy are reduced definitely. Tracheostomy Complications can be prevented by refined surgical techniques, use of high volume low pressure cuffed tracheostomy tubes and attentive post-operative nursing care. Yet complications of tracheomalacia and tracheal stenosis call for further improvement.

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.

National changes in pediatric tracheotomy epidemiology during 36 years

BACKGROUND

Information on the incidence, indications and morbidity of pediatric tracheotomy from a nationwide setting is sparse.

METHODS

From the nationwide Danish National Patient Registry, we identified all cases: 0-15-year-old children registered with a first-time tracheotomy from 1979 to 2014. We extracted the date of surgery, admission, discharge, age, gender, hospital, department, hospitalization length, hospital contacts, and diagnosis-code related to the surgery. We estimated age-adjusted incidence rates (AAIR) and annual (APC) and average annual percentage change (AAPC) of tracheotomy incidence.

RESULTS

A total of 510 children (328 boys, 63%) underwent tracheotomy. The median age at surgery was 8 years. The AAIR was 1.4/100,000 person-years (range 1.0-1.8) from 1980 to 2014. During 1979-2014, the AAPC decreased - 0.9% (95% confidential interval - 2.4; 0.8, p < 0.3). From 1979 to 2003 the APC decreased - 4.1% (95% CI - 5.4; - 2.8, p < 0.001) and from 2003 to 2014 the APC increased 6.6% (95% CI 2.0; 11.5, p < 0.001). Infants had the highest incidence (4.0/100,000 years) compared with the 12-15-year-olds (AAIR: 0.4/100,000 years). From 1979 to 2014 the most common indication for tracheotomy among children aged 0-2 years was congenital malformations (n = 48, 30%) and among children aged 3-11 and 12-15 years the most common indication was trauma (respectively n = 67, 36% and n = 85, 52%). During 2006-2014 the most common indications for all ages was neurological impairment (n = 25, 21%) and neoplasms (n = 20, 17%).

CONCLUSIONS

Pediatric tracheotomy was a rare surgical procedure with decreasing incidence rates from 1980-89 to 1990-99 and increasing incidence rates from 2000-2009 to 2010-2014. Indications and postoperative morbidity have changed adjunct to the treatment of chronic disorders.

Pediatric tracheotomy: A comparison of outcomes and lengths of hospitalization between different indications

OBJECTIVES

To assess outcomes of pediatric tracheotomy and duration of associated hospital stay according to indications.

SUBJECTS AND METHODS

In this retrospective study, subjects were 142 consecutive pediatric patients (<18 years old) who underwent tracheotomy at a tertiary referral medical center, National Taiwan University Hospital, in 1997-2012. Age, sex, indications, pre-operative status (oxygen demand, number of repeated intubations), and post-operative status (duration of weaning, length of hospital stay, mortality) were analyzed.

RESULTS

The indications included craniofacial anomalies (n = 19, 13.4%), upper airway obstruction (n = 41, 28.9%), neurological deficit (n = 58, 40.8%), prolonged ventilation (n = 15, 10.6%), and trauma (n = 9, 6.3%). Ninety-one patients (64.1%) were successfully weaned off ventilation after tracheotomy (40% in the prolonged ventilation group). Total hospital stay and duration of ventilation before tracheotomy were longest in patients with craniofacial anomalies (150.9 ± 98.8 days, p = 0.004; 108.8 ± 88.2, p < 0.001). The early tracheotomy group had a shorter duration of post-tracheotomy mechanical ventilation support than the late tracheotomy group (14.4 ± 19.0, n = 49 vs. 34.9 ± 58.6, n = 80, p = 0.004). Decannulation was successful in 20 patients (14.1%), with the highest rate in the upper airway obstruction group (n = 14, 34.1%) and lowest in the prolonged ventilation group (none). Thirteen patients (9.2%) died during admission from causes unrelated to tracheotomy.

CONCLUSION

Outcomes of pediatric tracheotomy and duration of hospitalization depend on indications. Children with craniofacial anomalies had earlier tracheotomy age and longer mechanical ventilation before tracheotomy resulted in longer hospitalization. Earlier tracheotomy can shorten the duration of post-tracheotomy mechanical ventilation in several conditions.

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.

Pediatric tracheostomy

Tracheotomy refers to a surgical incision made into a trachea. Tracheostomy, on the other hand, refers to a surgical procedure whereby the tracheal lumen is positioned in close proximity to the skin surface. Tracheostomy is an uncommon procedure in the pediatric population. When required tracheostomy is typically performed as an open surgical procedure under general anesthesia with the patient intubated. However, it may need to be performed under local anesthesia or over a rigid bronchoscope in the patient with a precarious airway. Over the past half century, the primary indication for pediatric tracheostomy has shifted from acute infectious airway compromise to the need for prolonged ventilatory support in neurologically compromised children. The surgical technique, choice of tracheostomy tube, and post-operative care requires a nuanced approach in infants and young children. This article will review these topics in a comprehensive fashion.

Pediatric Tracheotomies in an Asian Population: The Singapore Experience

Objective:

Over the past 2 decades, tracheotomy in children and infants has evolved from a primarily emergent procedure for upper airway obstruction into a semielective procedure for airway access in assisted ventilation. We present a 12-year retrospective review of tracheotomies performed in the pediatric population in Singapore.

Study Design and Setting:

We reviewed all tracheotomies performed in children below the age of 16 years in 2 tertiary pediatric medical centers in Singapore from January 1991 to December 2003. Indications for surgery are reviewed, and outcomes in terms of morbidity rate, mortality rate, postoperative rehabilitation, and duration of decannulation process were analyzed.

Results:

Tracheotomies were performed in 48 children during the study period. The mean age of patients was 3.24 years, with ages ranging from 16 days to 14 years. Sixty-three percent of tracheotomies were done within the 1st year of life. The chief indication was airway access for assisted ventilation. The overall complication rate was 31%. There were 13 attempts at decannulation, with 9 successes. No tracheotomy-related deaths occurred.

Conclusion:

Tracheotomy is a relatively safe procedure in children and infants. Lower decannulation rates and the evolving role of tracheotomy for early access in assisted ventilation permits earlier discharge with tracheotomy in situ.

Pediatric Tracheotomy: A 5-Year Experience in Düzce University Medical Faculty

Objective

Tracheotomy is one of the oldest surgical procedures. Pediatric tracheotomy indications have changed in recent decades. Currently, tracheotomy is performed because of prolonged intubation, upper airway obstruction, neuromuscular, and craniofacial anomalies instead of acute airway infections. This study aims to present our experience regarding indications and complications of tracheotomy in pediatric patients.

Methods

We retrospectively evaluated 17 pediatric patients who underwent tracheotomy because of prolonged intubation, increased pulmonary secretions, and upper respiratory tract obstruction from June 2010 to June 2015. The patients' age, gender, tracheotomy indications, duration of intubation, complications, and actual clinical condition were recorded.

Results

Tracheotomy was performed on 17 pediatric patients in our clinic. Discharged patients were followed with a 3-month routine check. Six patients (35.29%) had died because of a primary disease during follow-up, and one (5.88%) of them was a one-day-old newborn who had anomalies that were incompatible with life. In one patient, emergency tracheotomy was performed because of a tracheal trauma. None of the patients has been decannulated except one (5.88%). One (5.88%) patient had an accidental decannulation, while another had bleeding in the operation field. The total minor complication rate was 11.76%, and no major complication was observed. Two (11.76%) of the discharged patients underwent re-operation for widening of the tracheotomy stoma during their routine visit.

Conclusion

Currently, tracheotomy in pediatric patients is mostly performed for prolonged intubation and upper respiratory tract obstruction for which intubation is not possible. Tracheotomy enables the discharge of these patients after training their families.

Usefulness of permanent tracheostoma in chronic brain injured patients: a case series

Patients with severe neurological deficit, such as hypoxic ischemic injury, cerebral infarction, and traumatic brain injury, often show comatose mental status and require maintenance of long-term tracheostomy for pulmonary toileting. However, several complications, which are mostly related to the cannula, invariably occur. Permanent tracheostoma is a short, skin-lined, noncollapsing, self-sustaining opening by suturing the denuded skin lining to the margin of the tracheal stoma. This tube-free method is a useful alternative to make long-term airway without tube-related complications in chronic diseases, such as obstructive sleep apnea, and laryngeal cancer, however, it has not yet been reported in chronic brain injured patients. This case report illustrates 3 cases of vegetative patients in our rehabilitation clinic who underwent successful procedure of permanent tracheostoma. Permanent tracheostoma has some benefits associated with the free of tube-related complications, and can be considered as a useful alternative way for chronic brain injured patients with long-term tracheostomy.

Utility of routine postoperative chest radiography in pediatric tracheostomy

OBJECTIVES

Routine chest radiography following pediatric tracheostomy is commonly performed in order to evaluate for air-tracking complications. Routine chest radiography affords disadvantages of radiation exposure and cost. The primary objective of this study was to determine the utility of routine postoperative chest radiography following tracheostomy in pediatric patients. Secondary objectives were to compare the rates of postoperative complications by various patient and surgeon characteristics.

METHODS

All infants and children 18 years of age or less (n=421) who underwent tracheostomy at a single tertiary-care medical center from January 2000 to April 2009 were included in the study. A combination of data obtained from billing and administrative systems and review of electronic medical records were recorded and compiled in a database for statistical analysis.

RESULTS

Three air-tracking complications (2 pneumothoraces and 1 pneumomediastinum) were identified in our population of 421 pediatric patients, for an incidence of 0.71% (95% CI: 0.1-2.0%). No significant relationships were found between the incidence of air-tracking complication and surgical specialty, patient age, or type of procedure (elective, urgent/emergent).

CONCLUSIONS

Our study identified a low rate of pneumothorax and pneumomediastinum following pediatric tracheostomy. In all three cases, the pneumothorax was suspected clinically. This finding suggests that postoperative chest radiography should be reserved for cases where there is suspicion of a complication on the basis of intraoperative findings or clinical parameters.

Pediatric tracheotomies: a 37-year experience in 282 children

OBJECTIVE

To study the outcomes, complications, and indications for pediatric tracheotomies performed at a tertiary referral center.

METHODS

A retrospective review of hospital records from 1968 to 2005 was conducted to assess all pediatric patients who had undergone tracheotomies.

RESULTS

A total of 282 tracheotomies were performed on patients under 16 years of age. The median age at tracheotomy was 27 months. Upper airway obstruction (infectious diseases, n=101; laryngeal anomalies, n=33; trauma, n=36; tumor, n=33) was the most common indication for tracheotomy (n=203; 72%). Lesser number of patients (n=79; 28%) required tracheotomy for prolonged ventilation. Decannulation was carried out successfully in 71 patients (35%). Total complication rate was 18%; only three patients (1%) died from tracheotomy-related complications, with an overall mortality rate of 19%.

CONCLUSIONS

Pediatric tracheotomies were associated with a low incidence of procedure-related mortality and morbidity and successful decannulation in 35% of cases. The majority of procedures were performed due to upper airway obstruction which were most commonly caused by infectious diseases.

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.

Pediatric tracheotomy: 17 year review

OBJECTIVE

To study the outcomes, complications, and indications for pediatric tracheotomies performed at a major tertiary care children's hospital, Starship Children's Hospital in Auckland, New Zealand, over the period 1987-2003.

METHODS

A retrospective review of hospital records from 1987 to 2003 was conducted to assess all pediatric patients who had undergone tracheotomies.

RESULTS

A total of 122 tracheotomies (119 surgical, 3 percutaneous) were performed on patients less than 16 years of age. Upper airway obstruction (including craniofacial dysmorphism, n=40, and subglottic stenosis, n=18) was the most common indication for surgery (n=86; 70%) with a lesser number (n=36; 30%) requiring tracheotomy for prolonged ventilation. The median age at tracheotomy was 4.5 months in patients with upper airway obstruction and 16 months in those requiring prolonged ventilation. Decannulation was carried out successfully in 92 patients (75%), although 6 (6.5%) subsequently required recannulation. The overall complication rate was 51% (n=62). Early postoperative complications occurred in a total of 9 (7.4%) patients, including difficulties with ventilation in intensive care due to inadequate seal or tube position in 5 (4.1%), and accidental decannulation in 3 (2.5%). Late complications included localized granulation in most patients, for which 15 (12.3%) required intervention whilst under a routine planned general anesthetic. Major vascular erosion was not encountered in any patient, although 5 (4.1%) required intervention for minor bleeding associated with granulation tissue. Suprastomal collapse occurred in 13 patients (10.7%); but did not affect their subsequent decannulation, although 2 (1.6%) developed tracheotomy-related subglottic stenosis. Closure of tracheocutaneous fistulas was required in 16 (13.1%) decannulated patients. Only 2 patients (1.6%) died from tracheotomy-related complications, with an overall mortality rate of 14%.

CONCLUSIONS

Pediatric tracheotomies performed at Starship Children's Hospital between 1987 and 2003 were associated with a low incidence of procedure-related mortality and morbidity and successful decannulation in most cases. The majority of procedures were performed to treat upper airway obstruction, most commonly caused by craniofacial dysmorphism or subglottic stenosis.

Failed extubation in the neonatal intensive care unit

OBJECTIVE

To determine the causes of failed extubation in the Neonatal Intensive Care Unit (NICU) and the need for airway intervention.

STUDY DESIGN

Retrospective chart review.

SETTING

Tertiary care children's hospital.

PATIENTS

We identified all premature infants (gestational age <37 weeks) admitted to the NICU of a tertiary care children's hospital from January 1998 until December 2006 who underwent direct laryngoscopy and bronchoscopy (DLB) in the operating room (OR) for failed extubation. Data was collected on weight, gestational age, co-morbid conditions, number of failed extubations, findings at DLB and whether or not a tracheostomy was performed.

RESULTS

DLBs were performed on 63 patients to evaluate the cause of failed extubation. Group A comprised of 50 patients who underwent tracheostomy. They had an average gestational age of 30.0 weeks, birth weight of 1457g and number of failed extubations 2.68. Group B consisted of 13 patients who did not undergo tracheostomy. They had an average gestational age of 34.5 weeks, birth weight of 2309g and number of failed extubations 1.33. 56.0% of the tracheostomy group and 38.5% of the non-tracheostomy group had chronic lung disease (CLD). At endoscopy, 44% of Group A and 23.1% of Group B had some degree of subglottic stenosis.

CONCLUSION

Abnormal laryngotracheal findings are common in neonates who fail extubation. When compared to their counterparts with similar co-morbidities, neonates with CLD, gestational age of 30 weeks or below and low birth weight are twice as likely to have subglottic edema and fail extubation. They are also likely to be candidates for a tracheostomy.

[Tracheotomy in children]

OBJECTIVE

To inspect and describe the results of tracheotomies carried out at our ENT Department and to assess changes in indications over the last few decades.

MATERIAL AND METHODS

Retrospective study of 13 patients, aged 3 months to 14 years, admitted by the ENT Department to the Paediatric ICU at Puerta del Mar University Hospital for elective tracheotomy over a 92-month period.

RESULTS

The main indication is shared by obstructive respiratory insufficiency, post-surgery extubation failure and as a means of assisting ventilation in children requiring prolonged intubation.

CONCLUSIONS

In the last 30 years the indications for paediatric tracheotomy have changed and the number of children needing intubation for more than 20-30 days has increased. It is no longer an emergency procedure to overcome a blockage in the upper airways but has instead become a technique for maintaining assisted ventilation for the medium to long term.

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.

Complications of neonatal tracheostomy: a 5-year review

OBJECTIVE

Study the complication rate of tracheostomy in premature infants and identify contributing factors. Setting Two university-based tertiary care children's hospitals.

METHODS

The charts of 55 neonates who underwent tracheostomy between January 1997 and December 2002 were reviewed. Group 1 included 32 infants born weighing < 1000 grams. Group 2 included 23 infants born weighing > or = 1000 grams.

RESULTS

Group 1 infants had a higher incidence of comorbidities related to prematurity. Thirty-eight infants underwent tracheostomy due to ventilatory dependence, 13 for airway obstruction, and 4 for neurologic debilitation. Sixteen infants (29%) had a complication related to tracheostomy. There was no tracheostomy-related mortality.

CONCLUSIONS

Tracheostomy in the preterm infant has the potential for significant morbidity. Meticulous technique, surgeon experience and specialized care may play a role in reducing the complication rate. Complications are usually minor and do not require additional surgical intervention.

Starplasty: revisiting a pediatric tracheostomy technique

OBJECTIVE

To determine the efficacy the "starplasty" pediatric tracheostomy technique in reducing the incidence of major complications and tracheotomy-related death.

METHODS

Retrospective chart analysis of all the cases of starplasty performed at 2 tertiary care centers between 1990 and 2002.

RESULTS

There were 94 children in our cohort ranging in age from 2 days to 14 years. Of the patients, 47 (50%) were females and 47 (50%) were males and 60 of the children (64%) were younger than 1 year of age. Forty-one patients (44%) had neurologically related airway problems as their primary indication for tracheostomy, 34 (36%) had upper airway obstruction, and the remainder had pulmonary diseases, prolonged intubation, or metabolic-related airway problems. There were 41 short-term complications including 5 cases of tracheal tube dislodgement. There were no instances of pneumothorax or tracheostomy-related death. There were 26 long-term complications. There were no cases of clinically relevant suprastomal collapse that compromised decannulation and no instances of tracheal stenosis. Twenty-six patients underwent decannulation, all of whom developed a tracheocutaneous fistula (TCF). Two patients had spontaneous closure of the TCF; 9 patients underwent surgical repair of their fistulas, 53 patients remain tracheostomy-dependent, and 8 patients died of their primary disease.

CONCLUSION

The need for pediatric tracheotomy has increased as a consequence of our success in treating chronically ill children. Starplasty reduces the incidence of major complications, including pneumothorax and death from accidental decannulation. Its major drawback is the need for secondary reconstruction of a tracheocutaneous fistula.

Pediatric tracheostomy: a 13-year experience

Pediatric tracheostomy has been reported to be a surgical procedure with significant morbidity and mortality. The use of tracheostomy in airway management has changed over time as regards indication and outcome. A review of the last 13 years' experience in our institution was carried out to focus on this group of patients and the recent trends in airway management. A retrospective analysis of hospital records was done and information collected with respect to age, gender, indication for tracheostomy, duration, complications, and follow-up. Thirty-nine tracheotomies were done in 36 patients, of whom males outnumbered females 2:1. The mean patient age was 41.6 months while nearly a third were newborns. The indications were congenital and acquired obstructive lesions. Apart from nine cases, all have been treated and decannulated. Follow-up ranged from 1 month to 8 years, and decannulation time from 48 h to 45 months. Home tracheostomy care was very well managed by the parents. One tracheostomy-related death was encountered. Complications were minor and transient and occurred post-decannulation in our series, in contrast to the major complications, both acute and chronic, reported in the literature. More neonates and infants are undergoing tracheostomy and surviving. Pediatric tracheostomy is a safe procedure with home care by parents feasible.

Internal mandibular distraction to relieve airway obstruction in infants and young children with micrognathia

Micrognathia may cause upper airway obstruction requiring complex medical interventions and sometimes tracheostomy. The role of distraction techniques to lengthen the mandible is yet to be clarified. The aim of this paper is to present a series of five cases in which mandibular lengthening by osteotomy and internal distraction was used to relieve airway obstruction. Five patients whose ages ranged from 4-39 months (mean, 15 months) were managed at our center with internal distraction osteogenesis to relieve airway obstruction. Three patients had a tracheostomy, and two patients had refractory airway obstruction prior to distraction. Following osteotomy and insertion of internal distraction devices, the mandible was distracted a mean of 17 mm (range, 15-25 mm). The distraction devices were removed at the end of a consolidation period ranging from 3-10 weeks. Two of 3 patients with a tracheostomy were decannulated, while the third patient with tracheostomy is awaiting choanal atresia repair before being decannulated. The two patients who were not managed with a tracheostomy but who had persistent upper airway obstruction have not required further airway intervention after mandibular distraction. In conclusion, mandibular lengthening by distraction osteogenesis can relieve airway obstruction in infants and small children. This is a promising new technique that may avoid the need for tracheostomy in some infants with micrognathia, and facilitate early decannulation in those who have a tracheostomy.

Outcome in pediatric tracheotomy

OBJECTIVE

To investigate the outcome and related factors in pediatric tracheotomy.

DESIGN

Retrospective chart review.

SETTING

Tertiary pediatric academic hospital setting.

PATIENTS

The study included 181 children below the age of 18 years who underwent 185 tracheotomies between 1991 and 1995.

MAIN OUTCOMES AND MEASURES

Presenting symptoms and signs, indications, duration of follow-up, therapeutic and interval procedures, early and late complications, mortality, time to and success in decannulation.

RESULTS

There were 108 (59.7%) male patients and 73 (40.3%) female patients. The average age of the children at the time of tracheotomy was 3.8 +/- 5.3 years. The majority of the children were less than 1 year of age (n = 99, 54.7%). Airway obstruction was the leading indication for tracheotomy (59.6%), followed by ventilatory support (30.4%) and pulmonary toilet (9.9%). The average duration of follow-up was 931 +/- 790 days. There were no perioperative complications. Early postoperative complications were seen in 28 (15.5%) children including 12 (6.8%) major complications and 22 (12.2%) minor complications. Late complications were seen in 115 (63.5%) children, including 8 (4.4%) major complications and 107 (59.1%) minor complications. Overall mortality rate was 13.3%, but only 1 tracheotomy-related death was caused by tube displacement. Therapeutic procedures were performed in 43% of the children, including laryngotracheal reconstruction (13%), laser excision of the lesion (5%), and supraglottoplasty (3.9%). Decannulation was accomplished in 116 (64.1%) of the children with an average of 365 +/- 388 days with tracheotomy.

CONCLUSION

Tracheotomy is relatively safe in the pediatric population. Decannulation may be possible relatively quickly with resolution of the underlying problem.

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.

Enlargement of existing tracheostome using percutaneous dilators

Children requiring long-term mechanical ventilation or with abnormalities of the upper airway may need a tracheostomy for prolonged periods of time. For these children, insertion of a larger tracheostomy tube may be required to match somatic growth. We describe a new method of enlarging the tracheal stoma in children, based on the existing technique of percutaneous dilational tracheostomy.

Complications in pediatric tracheostomies

OBJECTIVE

To examine complications of pediatric tracheostomy.

STUDY DESIGN

Retrospective.

METHODS

Chart review of children undergoing tracheotomy or laryngeal diversion between 1990 and 1999.

RESULTS

Charts of 142 children were examined. Average age was 2.64 years (standard deviation [SD], 4.73 y) at surgery. Duration of tracheostomy was 2.08 years (SD, 1.72 y) for those decannulated, 3.12 years (SD, 2.5 y) for those still with a stoma, and length of follow-up for the whole group was 4.14 years (SD, 8.69 y). At last follow-up, 56% had a tracheostomy, 29% had none, and 15% had died; one death was tracheostomy-related. Three percent had intraoperative complications, 11% had complications before the first tracheostomy tube change, and 63% had complications after the first tube change. Thirty-four percent had a trial of decannulation; 85% of these were successful. Fifty-four percent of those decannulated had complications. Number of complications was not related to duration of follow-up. In-hospital mortality was congruent to mortality predicted by PRISM (Pediatric Rate of Mortality) scores.

CONCLUSIONS

Forty-three percent had serious complications involving loss of the tracheostomy airway (tube occlusion or accidental decannulation) or requiring a separate surgical procedure. Deaths directly attributable to tracheostomy complications occurred in 0.7%.

The role of postoperative chest radiography in pediatric tracheotomy

A postoperative chest radiograph has traditionally been obtained after tracheotomies to evaluate for the presence of a pneumothorax and to assess tube position. Several recent studies in adults have questioned the usefulness of routine postoperative chest radiography in uncomplicated cases, but the role of post-operative chest radiography in pediatric patients has not been previously reviewed. We performed this study to examine the clinical utility of post-tracheotomy chest radiography in pediatric patients and determine if this routine practice impacts patient management enough to merit continued usage. A retrospective review was performed of 200 consecutive pediatric patients who underwent tracheotomies by the otolaryngology service in a tertiary care pediatric hospital from January 1994 to June 1999. All patients received postoperative chest radiographs. Five of 200 patients had a new postoperative radiographic finding, with three requiring interventions. Two patients required chest tube placement for pneumothorax, and one patient required tracheostomy tube change for repositioning. Fifty-one patients, including both pneumothoraces, exhibited clinical signs of pneumothorax (decreased breath sounds or oxygen saturation) in the immediate postoperative period. Chest X-ray ruled out a pneumothorax in the remaining 49 patients. The majority of these 51 patients were less than 2 years old (94%, P=0.002) or weighed less than 17 kg (89%, P=0.004). Postoperative chest X-rays yielded clinically relevant information in 168 patients that fell into one or more of four high risk categories: age less than 2, weight less than 17 kg, emergent procedures, or concomitant central line placement. Avoiding chest X-rays in the remaining 32 patients would have resulted in potential savings of $5000, which does not reflect the actuarial cost of a missed complication. Since the majority of our patients (84%) fell into a high-risk category, we feel it would be prudent to continue obtaining postoperative chest radiographs following all pediatric tracheotomies.

The technology-dependent child

Improvements in the provision of oxygen, mechanical ventilation, tracheostomy care, enteral and parenteral nutrition, and dialysis have expanded the population of technology-dependent children. This article attempts to review pertinent points regarding these services, including common complications. Primary care and subspecialty physicians must smooth the transition of these children to the home environment, but a comprehensive team approach is necessary for the recognition of medical complications and provision of appropriate family teaching and psychosocial supports.

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.

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%.

Maturation of the pediatric tracheostomy stoma: effect on complications

The pediatric tracheostomy stoma can be matured via a technique that places 4-quadrant sutures from the tracheal cartilage to the dermis. This has the potential of decreasing the risk of accidental decannulation and the formation of granulation tissue. A retrospective analysis of 149 tracheostomies performed between January 1989 and December 1996 was done for the following factors: age, underlying diagnosis, indication for tracheostomy, type of tracheal incision, maturation of stoma, duration of tracheostomy, and early and late (>7 days) complications. Maturation of the stoma was performed in 88 (59.1%) of the 149 tracheostomies. There was an overall complication rate of 21.5% (32/149, not including granulation tissue formation). There were 9 (6.0%) early complications and 23 (15.4%) late complications. The overall incidence of tracheocutaneous fistulas occurred in 11 (11.2%) of the 98 decannulated patients: 6 (10.2%) of the 59 matured stomas and 5 (12.8%) of the 39 nonmatured stomas. Granulation tissue was found on subsequent laryngoscopy in 24 (27.3%) of the 88 matured stomas versus 23 (37.7%) of the 61 nonmatured stomas. There were no tracheostomy-related mortalities. Maturing the tracheostomy stoma resulted in a decreased morbidity from accidental decannulations and did not increase the incidence of tracheocutaneous fistulas or granulation tissue formation.

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.

Topographic variations in anatomical structures of the anterior neck of children: an ultrasonographic study

OBJECTIVE

Tracheostomies in children are frequently used for temporary airway support during surgical procedures. In pediatric patients with congenital craniofacial malformations, preoperative assessment of the delicate anatomy of the airway is necessary. The purpose of this study was to assess the ultrasonographic anatomy of the anterior neck with regard to the performance of tracheostomy.

STUDY DESIGN

Ultrasonographic investigation was done in 50 pediatric patients (age range, 6 to 15 years) to analyze the relationships among the anatomical structures that are of practical interest with respect to tracheostomy.

RESULTS

The data reveal that information concerning variations in anatomical structures lying in the immediate vicinity of the tracheostomy site was readily obtainable with the techniques used.

CONCLUSIONS

In pediatric patients requiring tracheostomy for surgical treatment of severe congenital craniofacial malformations, preoperative ultrasonography may be used to diagnose individual anatomical variations at the tracheostomy site.

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.

Lightwand intubation of infants and children

STUDY OBJECTIVE

To examine factors contributing to successful lightwand (lighted stylet) intubation of infants and children.

DESIGN

Prospective observational study.

SETTING

University hospital.

PATIENTS

125 children under age 10 years presenting for elective surgery.

INTERVENTIONS

Prototype lightwands specifically designed for pediatric patients were used. Intubations were done by anesthesia residents with little or no prior lightwand experience. All attempts were recorded on videotape. In a subgroup of 14 patients, an endoscopic view of the lightwand was also recorded with a flexible nasopharyngoscope.

MEASUREMENTS AND MAIN RESULTS

125 patients with a mean age of 3.0 years (+/- 2.4 years SD; range: 3 weeks to 9 years) were enrolled. 83.2% were intubated using the lightwand, including 75.5% (34 of 45) of infants weighing less than 10 kg. Of the 21 failed intubations, 8 were due to an inappropriately large endotracheal tube, as recognized during direct laryngoscopy; 4 were due to other reasons discussed; and 9 (persistent vallecular or esophageal entry) could not be explained from videotape analysis. Factors contributing to successful intubation included: (1) use of a shoulder roll and slight head extension; (2) conscientious alignment of airway axes; (3) anterior jaw lift to elevate the epiglottis; and (4) gentle handling of the lightwand to avoid displacing soft tissue. Inability to advance the lightwand despite correct glow is caused by entrapment in the vallecula, hang up of the lightwand on the aryepiglottic folds, subglottic narrowing, or vocal cord closure.

CONCLUSIONS

Lightwand intubation in children uses both tactile and visual cues regarding the location of the endotracheal tube tip. Attention to detail results in a high level of success among novice users of the pediatric lightwand. Endoscopic and external videotaping gave us a means of monitoring the progress of mechanical skills among novice users.

Airway management in children with craniofacial anomalies

Craniofacial anomalies (CFA) predispose children to airway obstruction. A retrospective study was conducted to describe airway intervention required to manage patients with craniofacial syndromes and diseases involving the midface and mandible (i.e., Pierre Robin, Apert, Treacher Collins, Saethre-Chotzen, CHARGE, Nager, Stickler, Goldenhar, and Pfeiffer). The type of airway intervention, duration of intervention, and associated physical and medical conditions were evaluated. One hundred nine patients had charts available for review and met inclusion criteria. Sixty-five of these patients required airway management, most commonly in the first month of life, ranging from positioning to tracheotomy. Nineteen patients required a tracheotomy. Associated medical conditions and feeding difficulties were associated with airway obstruction. This study evaluates factors that predispose children with CFA to have airway problems that need treatment, as well as the types of airway management that are necessary.

Percutaneous dilatational versus conventional open tracheotomy in a growing animal: a study in goats

Percutaneous dilatational tracheotomy (PDT) is a new technique for the introduction of a tracheal cannula. It has been performed successfully in adults; however, in children, the open conventional technique is preferred because of the technical limitations of PDT, with fear of tracheal stenosis and adverse effects on tracheal growth. The authors studied the applicability of PDT in a growing animal. Two groups of goat kids (aged 10 days) underwent PDT or conventional open tracheotomy. They were cannulated for 7 days. Three months after decannulation, the tracheas were analyzed macroscopically and microscopically. The coronal (lateral) diameter and the cross-sectional area at the level of the stoma were 4.7 mm (SEM, 0.23 mm) and 41 mm2 (SEM, 3.0 mm2) after open tracheotomy, versus 8.1 mm (SEM, 0.13 mm) and 58 mm2 (SEM, 4.6 mm2) after PDT (P < .001 and P = .023, respectively). The quotient of the stomal cross-sectional area and the normal cross-sectional area was significantly smaller after open tracheotomy than after PDT (P < .001), with a cross-sectional area reduction of 24% to 40% in the open group. The authors conclude that PDT can be performed in growing animals without an increased risk of tracheal stenosis and adverse effects on tracheal growth. They recommended that PDT be investigated in children in a clinical setting.

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.
