Randomized Controlled Trial Comparative Study Clinical TrialThe effect of delivery on umbilical arterial cord blood gases and lipid peroxides: comparison of vaginal delivery and cesarean section.
Umbilical arterial blood gas analysis is the most objective method to assess fetal well being at birth, is the gold standard assessment of uteroplacental function and fetal oxygenation/acid-base status at birth, and it excludes the diagnosis of birth asphyxia in approximately 80% of depressed newborns at term. This study was designed to determine the effect of the type of delivery on umbilical cord blood gases and on free radical activity together with antioxidation in the fetus. ⋯ The umbilical arterial PO2 was found to be higher in Group 3, and malondealdehyde and glutathione levels were lower in newborns of Group 2. It can be concluded that cesarean section with epidural anaesthesia is safer when lipid peroxides are concerned.
