Airway findings in children with tracheostomies: When is diagnostic bronchoscopy and laryngoscopy indicated?

Tracheal A-frame deformity and suprastomal collapse after pediatric tracheostomy

Objectives

To determine the incidence of A-frame deformity and suprastomal collapse after pediatric tracheostomy.

Study design

Retrospective cohort.

Methods

All patients (<18 years) that had a tracheostomy placed at a tertiary institution between 2015 and 2020 were included. Children without a surveillance bronchoscopy at least 6 months after tracheostomy were excluded. Operative reports identified tracheal A-frame deformity or suprastomal collapse.

Results

A total of 175 children met inclusion with 18% (N = 32) developing A-frame deformity within a mean of 35.8 months (SD: 19.4) after tracheostomy. For 18 children (18/32, 56%), A-frame developed within a mean of 11.3 months (SD: 15.7) after decannulation. There were 96 children developing suprastomal collapse (55%) by a mean of 17.7 months (SD: 14.2) after tracheostomy. All suprastomal collapse was identified prior to decannulation. Older age at tracheostomy was associated with a lower likelihood of collapse (OR: 0.92, 95% CI: 0.86-0.99, p = .03). The estimated 5-year incidence of A-frame deformity after tracheostomy was 32.8% (95% CI: 23.0-45.3) and the 3-year incidence after decannulation was 36.1% (95% CI: 24.0-51.8). Highly complex children had an earlier time to A-frame development (p = .04). At 5 years after tracheostomy, the estimated rate of suprastomal collapse was 73.7% (95% CI: 63.8-82.8).

Conclusions

Tracheal A-frame deformity is estimated to occur in 36% of children within 3 years after tracheostomy decannulation. Suprastomal collapse, which approaches 74% at 5 years after tracheostomy, is more common when tracheostomy is placed at a younger age. Surgeons caring for tracheostomy-dependent children should recognize acquired airway obstruction and appropriately monitor these outcomes.

Long-term Outcomes of Pediatric Tracheostomy Home Care in a Limited Resource Setting of Professional Home Nurse

Long-term outcomes of pediatric patients with a tracheostomy in developing countries where professional home nurse is not accessible has rarely been reported. We, therefore, investigated the prevalence and associating factors of long-term outcomes in these children. Retrospective chart review was conducted in 85 tracheostomized children who were discharged to home during January 2012 to December 2020. Tracheostomy home care was provided by caregivers who completed the tracheostomy home care program. Prevalence of unplanned readmission with acute respiratory problems within 30 days after the first hospital discharge was 17.6%. Lower respiratory tract infection (LRTI) after hospital discharge was found in 72.9% (median frequency of 1.0 episode/case/year). Among 80 children who had surveillance airway endoscopy, 46.3% demonstrated late tracheostomy-related airway complications. Independent factor associated with late tracheostomy-related airway complications was a follow-up period longer than 1 year. Decannulation success was found in 21.2%. Most of them had tracheostomy for their upper airway anomalies. The mortality rate was 7%. Most of them died from their underlying diseases. In conclusion, pediatric tracheostomy home care undertaken by caregivers is feasible in developing countries where home nurse is not available. The prevalence of unplanned readmission with acute respiratory problems within 30 days after hospital discharge and late tracheostomy-related airway complications were comparable with those reported in developed countries. However, we still had a high prevalence of post-tracheostomy LRTI which was a challenging problem that needed to be investigated and resolved.

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 .

Validation of the Seattle Suprastomal Safety Score (5S): A Novel Measure in Pediatric Tracheostomy-Dependent Patients

OBJECTIVE

Suprastomal collapse and granulation are common sequelae of pediatric tracheostomy. We present the first measure of suprastomal obstructive pathology, the Seattle Suprastomal Safety Score (5S), an instrument with 2 domains: collapse and granulation.

STUDY DESIGN

Cross-sectional repeated testing survey.

SETTING

Electronic survey.

METHODS

A library of images was assembled from still pictures of the suprastomal area in 50 patients who previously underwent trachea-bronchoscopy at a quaternary children's hospital. Five pediatric otolaryngologists and 2 pediatric pulmonologists reviewed the images in random, blinded fashion and provided 5S scores. Participants repeated this process 2 to 4 weeks later. Interrater agreement was calculated with an intraclass correlation coefficient (ICC) with a 2-way random-effects model and Fleiss's κ. Intrarater agreement was measured with an ICC using a 2-way mixed-effects model as well as with test-retest correlations using Spearman rank coefficient. All measures were performed separately on collapse and granulation domains.

RESULTS

ICC for interrater agreement was 0.88 (95% CI, 0.82-0.93) for collapse and 0.97 (95% CI, 0.96-0.98) for granulation, indicating almost perfect agreement. Fleiss's κ demonstrated moderate agreement for collapse and almost perfect agreement for granulation. ICC for intrarater agreement was 0.95 (95% CI, 0.93-0.97) and 0.99 (95% CI, 0.98-0.99) for collapse and granulation, respectively, indicating almost perfect agreement. Spearman rank correlation for test-retest demonstrated substantial agreement for collapse and almost perfect agreement for granulation.

CONCLUSION

The 5S demonstrates excellent interrater and intrarater agreement, making it highly reliable as a novel measure of suprastomal collapse and granulation in tracheostomy-dependent pediatric patients.

An Analysis of Tracheostomy Complications in Pediatric Patients With Scoliosis

OBJECTIVES/HYPOTHESISAL

To analyze tracheostomy-related complications in pediatric patients with scoliosis.

STUDY DESIGN

Retrospective chart review.

METHODS

A retrospective chart review of all patients with tracheostomy and scoliosis was performed at a single institution. The charts were reviewed for variables including difficulties with tracheostomy tube changes, poor positioning of tube, abnormal appearance of trachea, and emergency room visits and admissions for complications. Decannulation rates were also identified.

RESULTS

About 102 patients met inclusion criteria, 96 (94.1%) had scoliosis involving the thoracic spine, and 4 had scoliosis involving the cervical spine; 13 (12.8%) patients had documented poor positioning on tracheoscopy; 31 patients (30.3%) had at least one emergency room visit or admission for complications, such as accidental decannulation or bleeding from the tracheostomy; 19 (18.6%) patients required at least one tube change due to poor positioning, with 7 (6.9%) requiring multiple changes; 18 (17.7%) had reported difficulties with home tube changes. Custom length tubes were required in 9 patients (8.8%). The level of scoliosis was not associated with any of these complications. Abnormalities of the trachea, such as tortuosity, obstructive granulomas, or tracheomalacia, were seen in 35 patients (34.3%) on bronchoscopy. Scoliosis repair was performed in 18 patients (17.65%), of which two achieved decannulation. Ten patients (9.8%) overall were decannulated.

CONCLUSION

A portion of patients with scoliosis who are tracheostomy-dependent have anatomical abnormalities of the trachea and poor positioning of the tracheostomy tube. Decannulation rates are also lower in this population compared to the literature. Further work is required to elucidate if scoliosis predisposes patients toward tracheostomy-related complications.

Best Practice Recommendations for Pediatric Otolaryngology during the COVID-19 Pandemic

Objective

To review the impact of coronavirus disease 2019 (COVID-19) on pediatric otolaryngology and provide recommendations for the management of children during the COVID-19 pandemic.

Data Sources

Clinical data were derived from peer-reviewed primary literature and published guidelines from national or international medical organizations. Preprint manuscripts and popular media articles provided background information and illustrative examples.

Methods

Included manuscripts were identified via searches using PubMed, MEDLINE, and Google Scholar, while organizational guidelines and popular media articles were identified using Google search queries. Practice guidelines were developed via consensus among all authors based on peer-reviewed manuscripts and national or international health care association guidelines. Strict objective criteria for inclusion were not used due to the rapidly changing environment surrounding the COVID-19 pandemic and a paucity of rigorous empirical evidence.

Conclusions

In the face of the COVID-19 pandemic, medical care must be judiciously allocated to treat the most severe conditions while minimizing the risk of long-term sequelae and ensuring patient, physician, and health care worker safety.

Implications for Practice

The COVID-19 pandemic will have a profound short- and long-term impact on health care worldwide. Although the full repercussions of this disease have yet to be realized, the outlined recommendations will guide otolaryngologists in the treatment of pediatric patients in the face of an unprecedented global health crisis.
