Perspectives on neonatal and infant tracheostomy

Factors associated with liberation from home mechanical ventilation and tracheostomy decannulation in infants and children with severe bronchopulmonary dysplasia

OBJECTIVE

To identify factors associated with the timing of ventilator liberation and tracheostomy decannulation among infants with severe bronchopulmonary dysplasia (sBPD) who required chronic outpatient invasive ventilation.

STUDY DESIGN

Multicenter retrospective study of 154 infants with sBPD on outpatient ventilators. Factors associated with ventilator liberation and decannulation were identified using Cox regression models and multilevel survival models.

RESULTS

Ventilation liberation and decannulation occurred at median ages of 27 and 49 months, respectively. Older age at transition to a portable ventilator and at discharge, higher positive end expiratory pressure, and multiple respiratory readmissions were associated with delayed ventilator liberation. Surgical management of gastroesophageal reflux was associated with later decannulation.

CONCLUSIONS

Ventilator liberation timing was impacted by longer initial admissions and higher ventilator pressure support needs, whereas decannulation timing was associated with more aggressive reflux management. Variation in the timing of events was primarily due to individual-level factors, rather than center-level factors.

Successful and Rapid Reduction in Neurosedative and Analgesic Medications in Complex Infants with Severe Bronchopulmonary Dysplasia After Tracheostomy Placement: Experience with 24-hour Propofol Infusions

Infants with severe bronchopulmonary dysplasia may require high doses of neurosedative medications to ensure pain control and stability following tracheostomy placement. Subsequent weaning of these medications safely and rapidly is a challenge. We describe a 24-hour propofol infusion to reduce neurosedative medications in 3 high-risk infants following tracheostomy placement.

In-hospital mortality and length of hospital stay in infants requiring tracheostomy with bronchopulmonary dysplasia

PURPOSE

To investigate in-hospital mortality and hospital length of stay (LOS) in infants requiring tracheostomy with bronchopulmonary dysplasia (BPD).

METHODS

We explored the correlation between tracheostomy with in-hospital mortality and LOS in infant patients hospitalized with BPD, using the data from Nationwide Inpatient Sample between 2008 and 2017 in the United States. In-hospital mortality and LOS was compared in patients who underwent tracheostomy with those patients who did not after propensity-score matching.

RESULTS

A total of 10,262 children ≤2 years old hospitalized with BPD, 847 (8%) underwent tracheostomy, and 821 patients underwent tracheostomy were matched with 1602 patients without tracheostomy. Tracheostomy group was correlated with higher in-hospital mortality(OR(95%CI):2.98(2.25-3.95)) and prolonged LOS(absolute difference(95%CI):97.0(85.6-108.4)).

CONCLUSIONS

Tracheostomy was correlated with increased in-hospital mortality and prolonged LOS. Such information may contribute to better decision-making process between clinicians and parents regarding tracheostomy to manage parent expectations, as well as better interdisciplinary teamwork.

Maxillary Hypoplasia and Non-Invasive Ventilation: Literature Review and Proposed New Treatment Protocol

The impact of non-invasive ventilation (NIV) on pediatric maxillary growth is a subject of ongoing research considering its increased use in the pediatric population due to technological advancements and broader indications. This review examines the existing literature, encompassing original articles, case reports, and reviews, to evaluate the effects of NIV on maxillary development and explore potential treatment options. Although the majority of studies agree on the adverse effects of prolonged NIV on maxillary development, techniques for its correction remain understudied. Introducing a novel treatment protocol, we addressed the challenge of correcting severe midfacial hypoplasia in a child with congenital central hypoventilation syndrome (CCHS) undergoing NIV therapy, thus sidestepping the necessity for osteotomies. This proposed protocol holds promise in correcting the adverse impact of NIV on maxillary growth, emphasizing the need for further exploration into innovative treatment modalities.

Tracheostomy in Severe Bronchopulmonary Dysplasia-How to Decide in the Absence of Evidence

Infants with the most severe forms of bronchopulmonary dysplasia (BPD) may require long-term invasive positive pressure ventilation for survival, therefore necessitating tracheostomy. Although life-saving, tracheostomy has also been associated with high mortality, postoperative complications, high readmission rates, neurodevelopmental impairment, and significant caregiver burden, making it a highly complex and challenging decision. However, for some infants tracheostomy may be necessary for survival and the only way to facilitate a timely and safe transition home. The specific indications for tracheostomy and the timing of the procedure in infants with severe BPD are currently unknown. Hence, centers and clinicians display broad variations in practice with regard to tracheostomy, which presents barriers to designing evidence-generating studies and establishing a consensus approach. As the incidence of severe BPD continues to rise, the question remains, how do we decide on tracheostomy to provide optimal outcomes for these patients?

Multidisciplinary bronchopulmonary dysplasia care

INTRODUCTION

Bronchopulmonary dysplasia (BPD) is a chronic respiratory disease in neonates and infants, which often presents with multisystem organ involvement, co-morbidities, and prolonged hospital stays. Therefore, a multidisciplinary chronic care approach is needed in the severest forms of BPD to optimize outcomes. However, this approach can be challenging to implement. The objective of this article is to review and synthesize the available literature regarding multidisciplinary care in infants and children with established BPD, and to provide a framework that can guide clinical practice and future research.

AREAS COVERED

A literature search was conducted using Ovid MEDLINE, CINAHL, and Embase and several components of multidisciplinary management of BPD were identified and reviewed, including chronic care, team development, team members, discharge planning, and outpatient care.

EXPERT OPINION

Establishing a core multidisciplinary group familiar with the chronicity of established BPD is recommended as best practice for this population. Acknowledging this is not feasible for all individual centers, it is important for clinical practice and future research to focus on the development and incorporation of national consulting services, telemedicine, and educational resources.

Respiratory Outcomes for Ventilator-Dependent Children With Bronchopulmonary Dysplasia

OBJECTIVES

To describe outpatient respiratory outcomes and center-level variability among children with severe bronchopulmonary dysplasia (BPD) who require tracheostomy and long-term mechanical ventilation.

METHODS

Retrospective cohort of subjects with severe BPD, born between 2016 and 2021, who received tracheostomy and were discharged on home ventilator support from 12 tertiary care centers participating in the BPD Collaborative Outpatient Registry. Timing of key respiratory events including time to tracheostomy placement, initial hospital discharge, first outpatient clinic visit, liberation from the ventilator, and decannulation were assessed using Kaplan-Meier analysis. Differences between centers for the timing of events were assessed via log-rank tests.

RESULTS

There were 155 patients who met inclusion criteria. Median age at the time of the study was 32 months. The median age of tracheostomy placement was 5 months (48 weeks' postmenstrual age). The median ages of hospital discharge and first respiratory clinic visit were 10 months and 11 months of age, respectively. During the study period, 64% of the subjects were liberated from the ventilator at a median age of 27 months and 32% were decannulated at a median age of 49 months. The median ages for all key events differed significantly by center (P ≤ .001 for all events).

CONCLUSIONS

There is wide variability in the outpatient respiratory outcomes of ventilator-dependent infants and children with severe BPD. Further studies are needed to identify the factors that contribute to variability in practice among the different BPD outpatient centers, which may include inpatient practices.

Outcomes of infants with severe bronchopulmonary dysplasia who received tracheostomy and home ventilation

OBJECTIVE

To describe the survival rate, timing of liberation from the ventilator, and factors favorable for decannulation among infants with severe bronchopulmonary dysplasia (sBPD) who received tracheostomy.

METHODS

Demographics and clinical outcomes were obtained through retrospective chart review of 98 infants with sBPD who were born between 2004 and 2017, received tracheostomy at <1 year of age, and were followed in the Infant Tracheostomy and Home Ventilator clinic up to 4 years of age.

RESULTS

The number of infants with sBPD who received tracheostomy increased significantly over the study period. The median age at tracheostomy was 4 months (IQR 3, 5) or 43 weeks corrected gestational age; the median age at NICU discharge was 7 months (IQR 6, 9). At 48 months of age, all subjects had been liberated from the ventilator, at a median age of 24 months (IQR 18, 29); 52% had been decannulated with a median age at decannulation of 32 months (IQR 26, 39). Only 1 (1%) infant died. Multivariate logistic regression showed infants who were White, liberated from the ventilator by 24 months of age and have public insurance had significantly greater odds of being decannulated by 48 months of age. Tracheobronchomalacia was associated with decreased odds of decannulation.

CONCLUSION

Infants with sBPD who received tracheostomy had an excellent survival rate. Liberation from home ventilation and decannulation are likely to occur by 4 years of age.

Tracheostomy in infants with severe bronchopulmonary dysplasia: A review

In recent years, with increased survival of infants with severe bronchopulmonary dysplasia (BPD), long term ventilation due to severe BPD has increased and become the most common indication for tracheostomy in infants less than one year of age. Evidence shows that tracheostomy in severe BPD may improve short- and long-term respiratory and neurodevelopmental outcomes. However, there is significant variation among centers in the indication, timing, intensive care management, and follow-up care after hospital discharge of infants with severe BPD who received tracheostomy for chronic ventilation. The timing of liberation from the ventilator, odds of decannulation, rate of rehospitalization, growth, and neurodevelopment are all clinically important outcomes that can guide both clinicians and parents to make a well-informed decision when choosing tracheostomy and long-term assisted ventilation for infants with severe BPD. This review summarizes the current literature regarding the indications and timing of tracheostomy placement in infants with severe BPD, highlights center variability in both intensive care and outpatient follow-up settings, and describes outcomes of infants with severe BPD who received tracheostomy.

Weaning from the Ventilator in Bronchopulmonary Dysplasia

For the newborns needing respiratory support at 36 weeks postmenstrual age, regardless of the type of ventilation used, it is critical to take into account the mechanics properties of both airways and lungs affected by severe bronchopulmonary dysplasia (sBPD). Ventilator strategies, settings, and weaning must change dramatically after sBPD is established, but to date there is almost no high-quality evidence base supporting a specific approach to guide the optimal ventilator management and weaning in patients with sBPD. Weaning from invasive mechanical ventilation, management of the immediately postextubation period, and weaning from noninvasive ventilation in patients with sBPD are the topics covered in this chapter.

Morbidity and respiratory outcomes in infants requiring tracheostomy for severe bronchopulmonary dysplasia

OBJECTIVE

The decision for tracheostomy for bronchopulmonary dysplasia (BPD) is highly variable and often dictated by local practice. We aimed to characterize morbidity, mortality, and respiratory outcomes in preterm infants undergoing tracheostomy for severe BPD.

STUDY DESIGN

We retrospectively reviewed a single-center 4-year cohort of all infants born <33 weeks gestational age (GA) that required tracheostomy due to severe BPD. Indications for tracheostomy apart from BPD were excluded. Demographic information, comorbidities, respiratory management, age at tracheostomy, post-discharge respiratory outcomes, and survival were examined up to at least 5 years of age.

RESULTS

At a mean corrected GA of 43.3 weeks, 49 preterm infants with severe BPD required tracheostomy. Forty-six infants (94%) had long-term follow-up. Compared to survivors, the 12 (26.1%) infants that died were significantly more likely to be small for gestational age (SGA) or require treatment for pulmonary hypertension. GA, birth weight, sex, antenatal corticosteroid exposure, need for patent ductus arteriosus ligation, and magnitude of respiratory support at tracheostomy placement were not associated with mortality. At the latest follow-up, 97% were liberated from mechanical ventilation and 79% decannulated. Morbidities of the upper airway were common, and 13/27 (47%) decannulated infants had required airway reconstruction.

CONCLUSION

Preterm infants undergoing tracheostomy experienced significant mortality, particularly those who were SGA or had pulmonary hypertension. However, by 5 years of age, most infants liberalized from mechanical ventilation and decannulated. Magnitude of respiratory support at time of tracheostomy was not associated with mortality and should not deter intervention. Nearly half of patients required airway reconstruction before decannulation.

Assessment and treatment of tracheostomy tube manipulation: Effects of competing stimuli and protective equipment

Functional analyses (FA) are widely used in the assessment and treatment of problem behavior. However, with limited exceptions, the procedures are rarely applied to potentially dangerous behaviors involving medical equipment. The current study replicated and extended procedures previously used by Kurtz and Chin (2004) to assess and treat tracheostomy tube manipulation in a 5-year-old boy diagnosed with extensive medical and developmental conditions. FA results indicated that tracheostomy tube manipulation (i.e., touching, pulling, occluding) was automatically maintained. An augmented competing stimulus assessment was conducted to identify stimuli associated with low levels of tracheostomy tube manipulation and elevated levels of item engagement. A treatment package consisting of noncontingent access to competing stimuli with prompting and continuous application of protective equipment produced significant reductions in tracheostomy tube manipulation, as well as significant increases in toy engagement.

Secretion Management in Tracheostomized Infants using Unconventional Approaches and Outcomes: A Case Series

OBJECTIVE

This study aimed to increase the understanding of secretion management in infants with tracheostomies. In this case series, we describe objective evidence for an unconventional approach in infants refractory to conventional management techniques.

STUDY DESIGN

Case study of two NICU infants utilizing high-resolution manometry was undertaken using personalized oral stimulation protocols with fruity foods.

RESULTS

Oral stimulation improved infant swallowing to clear secretions and reduce the need for suctioning.

CONCLUSION

Innovative oral stimulation protocols are needed to improve swallowing in high-risk infants.

Characterization of Disease Phenotype in Very Preterm Infants with Severe Bronchopulmonary Dysplasia

Rationale: Bronchopulmonary dysplasia (BPD) is a heterogenous condition with poorly characterized disease subgroups.Objectives: To define the frequency of three disease components: moderate-severe parenchymal disease, pulmonary hypertension (PH), or large airway disease, in a referral cohort of preterm infants with severe BPD. The association between each component and a primary composite outcome of death before hospital discharge, tracheostomy, or home pulmonary vasodilator therapy was assessed.Methods: This was a retrospective, single-center cohort study of infants born at <32 weeks' gestation with severe BPD who underwent both chest computed tomography with angiography (CTA) and echocardiography between 40 and 50 weeks postmenstrual age between 2011 and 2015. Moderate-severe parenchymal lung disease was defined as an Ochiai score ≥8 on CTA. PH was diagnosed by echocardiogram using standard criteria. Large airway disease was defined as tracheomalacia or bronchomalacia on bronchoscopy and/or tracheoscopy or CTA.Measurements and Main Results: Of 76 evaluated infants, 73 (96%) were classifiable into phenotypic subgroups: 57 with moderate-severe parenchymal disease, 48 with PH, and 44 with large airway disease. The presence of all three disease components was most common (n = 23). Individually, PH and large airway disease, but not moderate-severe parenchymal disease, were associated with increased risk for the primary study outcome. Having more disease components was associated with an incremental increase in the risk for the primary outcome (2 vs. 1: odds ratio, 4.9; 95% confidence interval, 1.4-17.2 and 3 vs. 1: odds ratio, 12.8; 95% confidence interval, 2.4-70.0).Conclusions: Infants with severe BPD are variable in their predominant pathophysiology. Disease phenotyping may enable better risk stratification and targeted therapeutic intervention.

Impact of tracheostomy on language and cognitive development in infants with severe bronchopulmonary dysplasia

OBJECTIVE

The impact of tracheostomy on language and cognitive development in infants with severe bronchopulmonary dysplasia (BPD) is not known. We hypothesize that tracheostomy has an independent negative impact on language and cognitive development in infants with severe BPD.

STUDY DESIGN

This is a retrospective cohort study of de-identified data of infants with severe BPD who received tracheostomy at <2 years of age, compared with infants with severe BPD without tracheostomy. The primary outcomes measured were total language and cognitive scores at 2-3 years of age as determined by Bayley Scales of Infant and Toddler Development, 3rd Edition.

RESULTS

A total of 26 patients with tracheostomies and 28 patients without tracheostomies were analyzed. There was no significant difference in total language development or cognitive development between patients with tracheostomies and those without. Insurance status had an effect on language and cognition while controlling for trach status.

CONCLUSIONS

Tracheostomy does not independently impact the language and cognitive development of infants with severe BPD.

Health Care and Societal Costs of Bronchopulmonary Dysplasia

Despite significant technological advances and increasing survival of premature infants, bronchopulmonary dysplasia (BPD) continues to be the most prevalent major morbidity in surviving very low-birthweight infants. Infants with BPD are often sicker, require longer stays in the NICU, and accumulate greater hospital costs. However, care of the infant with BPD extends beyond the time spent in the NICU. This article reviews the costs of BPD in the health-care setting, during the initial hospitalization and beyond, and the long-term neurodevelopmental impact of BPD, as well as the impact on a family caring for a child with BPD.
