    Abstract:
    OBJECTIVE: The objective of the study was to determine the clinical and physiologic benefits of noninvasive respiratory support (NRS) (continuous positive airway pressure or noninvasive positive pressure ventilation) for infants with a Pierre Robin sequence (PRS). METHODS: Breathing patterns, respiratory efforts, and gas exchange were analyzed for 7 infants with a PRS during spontaneous breathing and during NRS. Clinical outcomes with duration of NRS and need for a tracheotomy and/or nutritional support was evaluated. RESULTS: Compared with spontaneous breathing, breathing patterns, respiratory efforts, and transcutaneous carbon dioxide pressures improved during NRS; the mean respiratory rate decreased from 55 ± 9 to 37 ± 7 breaths per minute (P = .063), the mean inspiratory time/total duty cycle decreased from 59 ± 9% to 40 ± 7% (P = .018), the mean esophageal pressure swing decreased from 29 ± 13 to 9 ± 4 cm H(2)O (P = .017), the diaphragmatic pressure-time product decreased from 844 ± 308 to 245 ± 126 cm H(2)O-second per minute (P = .018), and the mean transcutaneous carbon dioxide pressure during sleep decreased from 57 ± 7 to 31 ± 7 mm Hg (P = .043). All of the patients could be discharged successfully from the hospital with NRS. The mean duration of NRS was 16.7 ± 12.2 months. Six patients could be weaned from nutritional support, and none required a tracheotomy. CONCLUSIONS: NRS is able to improve breathing patterns and respiratory outcomes for infants with severe upper airway obstruction attributable to a PRS, which supports its use as a first-line treatment.
