Infants undergoing pyloromyotomy are not at risk for postoperative apnea. Staff of Sutter Community Hospitals Sleep Disorders Center.

Thirty term infants undergoing general anesthesia and pyloromyotomy had pre- and postoperative sleep studies to determine whether these infants were at risk for postoperative apnea. Sleep studies showed an improved respiratory disturbance index (RDI) after surgery. Postoperatively, apnea indices were lower and lowest oxygen saturation values were increased compared to the infants' preoperative status. We conclude that pyloromyotomy does not elicit postoperative apnea in term infants.
