Neurodevelopmental Outcomes at Two Years of Age for Premature Infants Diagnosed With Neonatal Obstructive Sleep Apnea

STUDY OBJECTIVES: Neurocognitive deficits have been shown in school-aged children with sleep apnea. The effect of obstructive sleep apnea (OSA) on the neurodevelopmental outcome of preterm infants is unknown. METHODS: A retrospective chart review was performed for all preterm infants ( 1 event/h. Regression analyses were performed to find a relationship between PSG parameters and cognitive, language, and motor scores. RESULTS: Fifteen patients (males: n = 10) were eligible for the study. Median postmenstrual age at the time of the PSG was 41 weeks (37-46). Median AHI for the cohort was 17.4 events/h (2.2-41.3). Median cognitive, language, and motor scores were 90 (65-125), 89 (65-121), and 91 (61-112), respectively. Mean end-tidal CO2 (median 47 mm Hg [25-60]) negatively correlated with cognitive scores (P = .01) but did not significantly correlate with language or motor scores. AHI was not associated with cognitive, language, or motor scores. CONCLUSIONS: The median score for cognitive, language, and motor scores for preterm infants with neonatal OSA were within one standard deviation of the published norm. Mean end-tidal CO2, independent of AHI, may serve as a biomarker for predicting poor cognitive outcome in preterm infants with neonatal OSA

The Use of Computer Decision Support for Pediatric Obstructive Sleep Apnea Detection in Primary Care.

Study Objectives To (1) describe outcomes from a computer decision support system (CDSS) for pediatric obstructive sleep apnea (OSA) detection in primary care; and (2) identity the prevalence of children meeting criteria for an OSA referral. Methods A CDSS for OSA was implemented in two urban primary care clinics. Parents of children (age 2 to 11 years) presenting to the clinic were asked if their child snored regularly, with a positive response resulting in six additional OSA screening items. Primary care providers (PCPs) received a prompt for all snoring children, listing applicable OSA signs and symptoms and recommending further evaluation and referral for OSA. Results A total of 2,535 children were screened for snoring, identifying 475 snoring children (18.7%). Among snoring children, PCPs referred 40 (15.4%) for further evaluation. The prevalence of additional OSA signs and symptoms ranged from 3.5% for underweight to 43.7% for overweight. A total of 74.7% of snoring children had at least one additional sign or symptom and thus met American Academy of Pediatrics guidelines criteria for an OSA referral. Conclusions A CDSS can be used to support PCPs in identifying children at risk for OSA. Most snoring children met criteria for further evaluation. It will be important to further evaluate this referral threshold as well as the readiness of the sleep medicine field to meet this need

Polysomnography Reference Values in Healthy Newborns

Study objectives: Polysomnography (PSG) is increasingly used in the assessment of infants. Newborn PSG reference values based on recent standardization are not available. This study provides reference values for PSG variables in healthy newborn infants. Methods: Cross-sectional study of normal term newborn infants using standardized PSG collection and American Academy of Sleep Medicine interpretation criteria. Results: Thirty infants born between 37 and 42 weeks gestation underwent PSG testing before 30 days of age (mean 19.6 days). The infants had a mean sleep efficiency of 71% with average proportions of transitional, NREM and REM sleep estimated at 16.1%, 43.3% and 40.6% respectively. Mean arousal index was 14.7 events/h with respiratory arousal index of 1.2 events/h. Mean apnea-hypopnea index (AHI) was 14.9 events/h. Central, obstructive, and mixed apnea indices were 5.4, 2.3, and 1.2 events/h respectively. Mean oxygen saturation in sleep was 97.9% with a nadir of 84.4%. Mean end tidal CO2 was 35.4 mmHg with an average of 6.2% of sleep time spent above end-tidal CO2 45 mmHg and 0.6% above 50 mmHg. Conclusions: The sleep efficiency was significantly lower and the AHI was significantly higher compared to healthy children older than 1 year. The AHI was also higher than reported in healthy infants older than 1 month. These findings suggest current severity classifications of sleep apnea may not apply to newborn infants

Robin sequence: what the multidisciplinary approach can do

Robin sequence (RS) is a commonly encountered triad of micrognathia, glossoptosis, and airway obstruction, with or without a cleft palate. The management of airway obstruction is of paramount importance, and multiple reviews and retrospective series outline the diagnosis and treatment of RS. This article focuses on the multidisciplinary nature of RS and the specialists’ contributions and thought processes regarding the management of the RS child from birth to skeletal maturity. This review demonstrates that the care of these children extends far beyond the acute airway obstruction and that thorough monitoring and appropriate intervention are required to help them achieve optimal outcomes

Correlation between the clinical severity of laryngomalacia and endoscopic findings

Objective: To correlate the clinical severity of laryngomalacia (LM) with endoscopic findings, swallowing evaluations and polysomnography in a cohort of patients. Method: We conducted a retrospective analysis between 2017-2018 on a cohort of patients diagnosed with upper airway obstruction (UAO), stridor, noisy breathing or laryngomalacia. This study took place at the Pediatric Pulmonology Department, Riley Children's Hospital, Indianapolis, United States of America. Results: There were 157 patients with laryngomalacia included in the study. Patients with severe LM were significantly younger than those with mild LM (p=0.0214) and moderate LM (p=0.0220). Subjects with type I of LM were significantly older than type III (p=0.0051). When associations were tested between polysomnogram (PSG) variables and clinical severity, there were significant associations with age at PSG. The overall apnea-hypopnea index (AHI) in mild (p=0.0103) and moderate (p=0.0242) were significantly lower than the severe group. The rapid eye movement (REM) AHI was significantly lower in moderate cases than severe (p=0.0134). The end-tidal carbon dioxide (EtCO2) peak was significantly lower in mild cases than severe (p=0.0141). The total sleep time (TST) peripheral capillary oxygen saturation (SpO2) 90% occurs in both mild (p=0.0197) and moderate (p=0.0498) were significantly lower than the severe group. Conclusions: The severity of the clinical manifestations of LM did not correlate with the different endoscopic types in our study. The presence of cyanosis was associated with type III LM. Rapid eye movement AHI and EtCO2 in polysomnogram were remained significantly associated with clinical severity

Apical Lung Herniation Associated with Continuous Positive Airway Pressure in a 4-Year-Old Girl

We report a case of apical lung herniation through the superior thoracic aperture of an obese child using nocturnal CPAP. Lung herniation has been described in association with congenital thoracic abnormalities and elevated intra-thoracic pressure, such as trauma. This patient was hospitalized with community acquired pneumonia and required nocturnal CPAP for treatment of concurrent obstructive sleep apnea. Her lung hernia was discovered incidentally on routine follow-up chest radiography and resolved with cessation of CPAP treatment. Lung herniation in association with the use of continuous positive airway pressure (CPAP) has not been previously described

NREM Sleep Parasomnia Associated with Chiari I Malformation

Parasomnias are common sleep disorders in children, and most cases resolve naturally by adolescence.1 They represent arousal disorders beginning in NREM sleep and are generally non-concerning in children. The diagnosis can usually be made by clinical assessment, and testing with polysomnography is not routinely indicated.2 However, in certain cases with atypical features, polysomnography and more extensive neurologic evaluation are medically indicated
