Background: Current recommendations for term women undergoing cesarean delivery with general anesthesia include maintenance of left lateral tilt for uterine displacement until delivery. No randomized controlled trial on the effect of the maternal position on blood pressure during elective cesarean delivery under general anesthesia has been investigated.
Methods: One hundred parturients who underwent cesarean delivery under general anesthesia with an LMA were randomized to the supine group (n=50) or 15° left tilt group (n=50). The primary outcome was the incidence of hypotension (defined as an SBP was less than 80% of baseline from the induction to delivery or SBP less than 90 mmHg).
Results: The primary outcome was the incidence of hypotension and the incidence of hypotension of left tilt group and supine group were 2% and 10% respectively and there was no significant difference (P=0.09).The secondary outcome of the first-insertion attempt success rate of SLMA was the same in both groups: 100%. Time to effective ventilation was 22.4+1.8 s for the left tilt group and 22.3+1.6 s for the supine group and there was no significant difference (P=0.64).Time from induction to delivery was 8.8 ± 1.2 min for the left tilt group and 8.4 ± 1.1 min for the supine group and there was no significant difference (P=0.17).There were no significant differences in APGAR scores at 1 and 5 min and umbilical artery cord pH between the two groups. And we did not find regurgitation or aspiration in any of the parturients.
Conclusions: There was no significant difference between the maternal supine position and left tilt position at the incidence of hypotension during elective cesarean delivery with general anesthesia in healthy term women.
