Postoperative apnea of ex-premature infants after inguinal herniorrhaphy

초록

Objectives: To determine 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 expremature infants undergoing inguinal herniarepair from March2010 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% (95% CI 1.0-13.7).Type of anesthetic durgs (sevofluranevs. desflurane and atracuriumvs. rocuronium) showed no statistical difference. A significant difference was observed inbronchopulmonary dysplasia (p=0.03), weight at surgery (p=0.03) and PCA (p=0.02) between the PAAgroup and non-PAAgroup. Conclusion: Compared to the drugs used in the past, currently used general anesthetics seem to be more safe. Selection between sevoflurane and desflurane, and between atracurium and rocuroniumcan be made with confidence.
