Overnight observation in former premature infants undergoing inguinal hernia repair.
BACKGROUND: Overnight observation for apneic events is standard practice in former preterm infants. However, the literature supporting current protocols is dated. Therefore, we retrospectively evaluated the post-anesthetic risks in these patients.
METHODS: A retrospective review was conducted on former preterm infants admitted after an inguinal herniorrhaphy between 1/00 and 10/09. The protocol for overnight admission was for patients born before 37 weeks gestation who are less than 60 weeks post-conceptional age (PCA).
RESULTS: There were 363 patients, of which 23 were(group 1), 244 were 40 to 49.9 weeks PCA (group 2), and 96 were 50 to 60 weeks PCA (group 3). Events registered by alarms occurred in 4 patients (1.1%), 2 from group 1 and 2 from group 2. In Group 1, one occurred during nasogastric tube placement and resolved spontaneously. In group 2, one was apnea-induced bradycardia that resolved spontaneously, and one was in a patient on home monitors with an event similar to home reports. There were no events in group 3.
CONCLUSION: Conservative guidelines for overnight observation after inguinal hernia repair could be set for patients born before 37 weeks gestation who are under 50 weeks PCA.
