Objectives: We tried to find out the impact of anesthetic drugs, being used recently, on the occurrence of postanesthetic apnea (PAA) after inguinal hernia repair in premature infants.
Methods: A retrospective chart review of 61 ex-premature infants undergoing inguinal hernia repair from March 2010 to December 2013 was undertaken. Collected data included gestational age at birth, postconceptual age (PCA), weight at birth, weigh at surgery, past and current medical history, type of inhalation anesthetics, type of muscle relaxants, anesthetic record, and presence of apnea.
Results: The incidence of postanesthetic apnea was 4.9% and its 95% exact confidence interval calculated by the Clopper-Pearson method was 1.0% to 13.7%. Type of anesthetic durgs (sevoflurane vs. desflurane and atracurium vs. rocuronium) showed no statistical difference. A significant difference was observed in bronchopulmonary dysplasia (p=0.03), weight at surgery (p=0.03) and PCA (p=0.02) between the PAA group and non-PAA group.
Conclusion: Compared to the drugs used in the past, currently used general anethetics seem to be more secure. Selection of the type of inhalation anesthetics between sevoflurane and desflurane, and muscle relaxants between atracurium and rocuronium can be made with confidence.
