Objective: The purpose of this prospective randomised study was to determine the effect of routine cervical dilatation during elective caesarean section on maternal morbidity.
Methods: Participants with indication for elective caesarean section were randomly allocated to two groups. Group A (n = 200) women with intraoperative cervical dilatation; group B (n = 200) women with no intraoperative cervical dilatation.
Results: No demographic differences were observed between groups. There was no significant difference between groups in infectious morbidity (P = 0.87) (relative risk (RR) 1.11, 95% confidence interval (CI) 0.58–2.11), endometritis (P = 0.72) (RR 1.68, 95% CI 0.39–7.14), febrile morbidity (P = 0.66) (RR 1.21, 95% CI 0.51–2.87), wound infection (P = 0.82) (RR 1.11, 95% CI 0.44–2.81), endometritis (P = 0.72) (RR 1.68, 95% CI 0.39–7.14) or urinary tract infection (P = 1.00) (RR 1.00, 95% CI 0.28–3.50), and estimated blood loss (P = 0.2). However, group A had longer operative times compared with the group B (P = 0.01).
Conclusion: Intraoperative digital cervical dilatation during elective caesarean section did not reduce blood loss and postoperative infectious morbidity. The routine digital cervical dilatation during elective caesarean section is not recommended.
