Abstract

Introduction: Considering the high prevalence of cesarean section and its methods, this study was conducted with the aim of determining the relationship between rectus ablation in cesarean section and postoperative pain and abdominal wall muscle thickness.

Methods: In this randomized controlled clinical trial, 80 pregnant women candidates for caesarean section, according to the inclusion criteria, were randomly divided into two intervention groups (40 people: rectus muscle repair) and control (40 people). Pain was evaluated by visual pain index (VAS) and abdominal wall muscle thickness and rectus muscle distance.

Results: The intensity of pain in the control group compared to the intervention, when getting out of bed (6.68 ± 0.57 vs. 7.73 ± 0.64, P<0.001) and 12 hours (5.70 ± 0.82 vs. 6.93 ± 0.73, P<0.001), 24 hours (4.63 ± 0.70 vs. 6.15 ± 0.70, P<0.001), 72 hours (4.63 ± 0.70 vs. 6.15 ± 0.70, P<0.001) and one week later (1.08 ± 0.27 vs. 1.63 ± 0.49, P<0.001), was lower. In the intervention group compared to the control, the need for painkillers was more (77.5 vs. 40.0%, P = 0.001) and diastasis recti in the epigastric area (12.50 ± 1.57 vs. 22.45 ± 1.52 mm, P<0.001) and hypogaster (12.90 ± 1.19 vs. 22.25 ± 0.81 mm, P<0.001), were lower.

Conclusion: The re-approximation of rectus abdominis muscle during cesarean section reduces the thickness of the abdominal wall muscles and diastasis recti. But on the other hand, it increases the amount of pain and the need for painkillers.
