Effects of closure versus non-closure of the visceral and parietal peritoneum at cesarean section: does it have any effect on postoperative vital signs? A prospective randomized study.

Objective: To investigate the effect of peritonization at cesarean section on postoperative vital signs which was thought to be an indirect finding secondary to increased sympathetic activity originated from pain caused by stretched peritoneum.

Methods: One hundred and thirty-three pregnant women were randomized to four groups; Closure of parietal peritoneum only (group 1; n = 32), closure of visceral and parietal peritoneums (group 2; n = 32), no closure of peritoneums (group 3; n = 32) and closure of the visceral peritoneum only (group 4; n = 32). All participants were monitored for blood pressure, pulse activity and hourly urinary output during the first postoperative 24 h.
