Aims In infants with chronic neonatal lung disease (CNLD), we aimed to identify predictors of home oxygen duration, predictors of discharge oxygen flow rates, and the association of oxygen flow rates with respiratory outcomes. Methods Infants with CNLD requiring home oxygen in 2016 and 2017 were retrospectively reviewed. Hazard ratios (HR) were estimated from Cox proportional hazards regression models in the cohort. A multinomial logistic regression model examined the effects of maternal and infant variables on discharge oxygen flow rates. Kruskal–Wallis test with univariate linear regression and Fisher's exact test with binomial univariate logistic regression were used to examine associations between oxygen flow groups and post‐discharge clinical variables. Results One hundred and forty‐nine infants were included. Median corrected gestational age (CGA) at oxygen cessation was 6.8 months (interquartile range, 4.4) with 87.2% of infants weaned by 12 months CGA. Shorter initial neonatal intensive care unit (NICU) stay predicted faster oxygen weaning at 9 months (HR, 0.99; 95% confidence interval [CI], 0.98–1.00, p = .02) and 12 months (HR, 0.99; 95% CI, 0.98–1.00, p = .02). Infants with hypercarbia at discharge or discharged from NICU at higher CGA had higher odds of requiring ≥ 200 ml/min relative to ≤ 125 ml/min oxygen. Infants discharged with > 250 ml/min oxygen were more likely to have a respiratory‐related admission before 2 years chronological age. Conclusion Shorter initial NICU stay was the best predictor of earlier home oxygen cessation. At NICU discharge, infants with hypercarbia or a higher CGA may require more home oxygen and experience more respiratory‐related hospital admission in the first 2 years of chronological age.
Dual and H‐type tracheoesophageal fistulae can present major diagnostic and management difficulties. A methodological approach with flexible bronchoscopy and a guide wire cannulation technique was used to diagnose, localize, and aid operative surgical management in five children with dual and H‐type tracheoesophageal fistulae. All children had successful outcomes.
Aim: Aerodigestive clinics (ADCs) are multidisciplinary programmes for the care of children with complex congenital or acquired conditions affecting breathing, swallowing and growth. Our objective was to describe the demographic, clinical, etiological and investigational profile of children attending the inaugural ADC at a tertiary paediatric centre in Queensland. Methods: Children referred to the ADC at Queensland Children's Hospital from August 2018 to December 2019 were included. Data on clinical, growth and lung function parameters, bronchoscopy and upper gastrointestinal endoscopy findings, thoracic imaging and comorbidities were retrospectively analysed. Results: Fifty-six children (median (range) age 4 years (3 months-15 years); 18 female) attended the ADC during this 17-month period. Forty-six (82%) children had previous oesophageal atresia with tracheo-oesophageal fistula; 43 of these were type C. Previous isolated oesophageal atresia, congenital diaphragmatic hernia and congenital pulmonary malformation were the underlying disorder in three (5%) children each, with one child having a repaired laryngeal cleft. Vertebral Anal Tracheo Esophageal Renal Limb anomalies (VACTERL)/Vertebral Anal Tracheo Esophageal renal anomalies (VATER) association was seen in 21 (38%) children. Growth was adequate (median weight and body mass index z-score −0.63 and −0.48, respectively). Thirty-four (61%) children reported ongoing wet cough, with 12 (21%) requiring previous hospital admission for lower respiratory tract infection. Fourteen (25%) had bronchiectasis on computed tomography chest and 33 (59%) had clinical tracheomalacia, apparent on bronchoscopic examination in 21 patients. Dysphagia was reported in 15 (27%) children, 11 (20%) were gastrostomy feed-dependent and 5 (9%) had biopsy-proven eosinophilic oesophagitis. Conclusion: High proportion of children attending the ADC have ongoing respiratory symptoms resulting in chronic pulmonary suppuration and bronchiectasis. Potential benefits of this model of care need to be studied prospectively to better understand the outcomes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
