Insights
Polysomnography (PSG) is crucial for diagnosing breathing issues in complex newborns. This study shows PSG effectively identifies obstructive apnea and guides interventions, leading to improved clinical outcomes in term and preterm infants.
Area of Science:
- Neonatal Medicine
- Sleep Medicine
- Pediatric Pulmonology
Background:
- Recurrent desaturation episodes and suspected obstructive apnea are common concerns in neonatal intensive care units (NICUs).
- Polysomnography (PSG) is a key diagnostic tool for evaluating these conditions in infants.
Purpose of the Study:
- To characterize term and preterm infants undergoing PSG for respiratory issues.
- To determine the prevalence of abnormal PSG findings and identify subsequent interventions.
- To assess the diagnostic utility of airway and swallow evaluations alongside PSG.
Main Methods:
- A retrospective cohort study was conducted on infants evaluated with PSG in the NICU.
- Data were collected from January 2012 to April 2018.
- Infant characteristics, PSG indications, comorbid conditions, and intervention outcomes were analyzed.
Main Results:
- PSG was performed on 31 infants (15 term, 16 preterm); 97% showed abnormal apnea-hypopnea indices, predominantly obstructive.
- Interventions based on PSG findings were implemented in 77% of infants.
- Otolaryngology and swallow evaluations revealed abnormalities in a significant proportion of infants, aiding management.
Conclusions:
- Inpatient PSG is valuable for evaluating and managing complex term and preterm infants with respiratory issues in the NICU.
- PSG findings effectively guide targeted therapies, leading to resolution of clinical signs in most infants.
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.
