Abstract
STUDY OBJECTIVES: (1) To determine the characteristics of term and preterm infants for whom polysomnography (PSG) was used as a primary diagnostic tool in infants with recurrent desaturation episodes, suspected obstructive apnea, or both, and the prevalence of abnormal studies. (2) To identify the interventions following PSGs. (3) To assess the added value of airway and swallow evaluations. METHODS: Retrospective cohort study of infants evaluated by PSG in the Neonatal Intensive Care Unit at New York-Presbyterian Hospital-Weill Cornell from January 2012 to April 2018. RESULTS: PSGs were performed on 31 infants; 15 (48%) term and 16 (52%) preterm infants. Indications for PSG were persistent desaturations (n = 24), suspected obstructive apnea (n = 15), and stridor (n = 2). Primary comorbid conditions were respiratory (n = 11), craniofacial (n = 9), airway anomalies (n = 6), and neurologic (n = 5). The apnea-hypopnea index was abnormal in 30 (97%) infants. Of those, 23 (74%) were severe, 7 (23%) were moderate, and 1 was normal (3%). Apneic events were predominantly obstructive in 23 infants and predominantly central in 6. The apnea-hypopnea index improved in all but 1 follow-up PSG. The PSG findings resulted in interventions in 24 (77%) infants, in addition to concomitant otolaryngology evaluations (abnormal in 20/25) and swallow studies (abnormal in 9/14). Clinical signs completely resolved in 22 (71%) infants. CONCLUSIONS: This is one of the first reports on the diagnostic value of inpatient PSGs in the neonatal intensive care unit in infants with recurrent desaturation episodes, suspected obstructive apnea, or both. Our findings indicate that PSG is an important tool in evaluating and targeting therapies in complex term and preterm infants with a wide variety of comorbidities.
