Fig. 2From: Adequacy of maternal anesthesia depth with two sodium thiopental doses in elective caesarean section: a randomized clinical trialEnd tidal Sevoflurane concentrations at different phases of surgery. End tidal sevoflurane concentration peaked at the point of uterine traction in both groups, the differences were significant for the closure of uterus (P-value = 0.046), subcutaneous tissue (P-value = 0.036), and skin closure (P-value = 0.046)Back to article page
