Prospective, non-randomized, parallel group, comparative observational study to compare maternal and neonatal outcome after regional and general anesthesia for Lower Segment Caesarean Section

Abstract

Background: LSCS is a routine obstetric procedure performed under general anesthesia (GA) or regional anesthesia (RA). Choice of anesthesia depends on factors like gestational age, parity, co-morbidities, urgency of situation, etc. Both GA and RA involve the use of various medications which may influence maternal and neonatal outcome. As there are few studies comparing maternal and fetal outcome in RA and GA for LSCS in Indian population, the present study was taken up. Objectives of the study was to compare the maternal and neonatal outcome after RA and GA for LSCS.Methods: 60 subjects with indications for LSCS were assigned non-randomly into two groups, 30 for GA and 30 for RA, at the discretion of anesthesiologist. The demographic, anthropometric and clinical data was recorded for all subjects. The maternal outcome after RA and GA for LSCS was assessed by parameters like maternal blood loss, postoperative pain, postoperative nausea and vomiting, maternal satisfaction and neonatal outcome by parameters like birth weight, APGAR scores and NICU admissions. The maternal and neonatal outcome between the two groups was compared.Results: All subjects had clear indications for CS. In most of the subjects it was undertaken as an emergency procedure. GA was preferred in high risk subjects. Maternal blood loss, postoperative pain, NICU admissions, need for resuscitation was less under RA compared to GA. There was no difference in PONV, maternal satisfaction, birth weight and need for intubation.Conclusions: LSCS under RA showed a more favourable maternal and neonatal outcome.
