Does general anesthesia compared to lumbar epidural analgesia improve newborn outcomes in elective cesarean section?
Does general anesthesia compared to lumbar epidural analgesia improve newborn outcomes in elective cesarean section?
General anesthesia and lumbar epidural analgesia both result in vigorous, well-oxygenated infants during elective cesarean section, with neither technique being clearly superior.
Neither GA nor LEA shows clear neonatal superiority in elective cesarean; leaves open optimal technique selection pending higher-level evidence.
Controversy exists concerning the choice of anesthetic technic for elective cesarean section. Several maternal and newborn parameters were compared during general anesthesia (GA) and lumbar epidural analgesia (LEA). High inspired maternal O2 levels were achieved with both technics. Vigorous, well-oxygenated infants with good umbilical-cord acid-base values were delivered during both GA and LEA. Umbilical artery and vein pH were better with GA, but 1-minute Apgar-minus-color scores were higher and time to sustained respiration was shorter with LEA. On the basis of this study, neither technic can be vigorously recommended over the other from the standpoint of the newborn's condition.
