OBJECTIVE
To determine which type of blunt expansion of a low transverse uterine incision during operative delivery is associated with decreased blood loss and intra- and post-operative morbidity for a caesarean section (CS).
METHODS
The prospective randomised-controlled trial was conducted at the Department of Obstetrics and Gynecology, Bezmialem University Hospital. The patients were randomly assigned to a group that received a cephalad-caudad (n = 55) or transverse (n = 57) blunt expansion of the low transverse uterine incision. Intra- and post-operative morbidity at caesarean delivery in short-term including blood loss, operating time, post-operative pain with the faces pain rating scale, and post-operative morbidity were analysed.
RESULTS
The changes in both haemoglobin (p < 0.01) and haematocrit (p < 0.01) from the pre-operative to post-operative values, estimates of blood loss (p < 0.01) were significantly lower in cephalad-caudad group and the post-operative haematocrit concentrations (p = 0.02) were significantly greater in cephalad-caudad group when compared with the transverse group. The damage of parametrial and uterine vessels into lateral edges were recorded in 11 (19.6%) patients in transverse group and 7 (12.9%) patients in cephalad-caudad group and there is no statistical significance between groups in terms of these parameters (p > 0.05, 95% CI 0.19, 1.63).
CONCLUSIONS
Our findings suggest that cephalad-caudad blunt expansion of the low transverse uterine incision decreases blood loss compared to transverse blunt dissection.
