Routine Cervical Dilatation at the Non-labour Caesarean Section and Its Influence on Postoperative Pain

Caesarean section is a common method of delivery in obstetrics. With the recent increase in the rate of this procedure, it is wise to understand and implement the optimal surgical technique. Therefore, different operational methods have been defined to reduce the risk of peri/post-operative morbidity.

The digital dilatation of cervix during elective caesarean section has still been a concern when evaluating this issue. This procedure is supposed to help the drainage of blood and lochia postpartum, thus reducing infection or the risk of postpartum haemorrhage (PPH). However, on the contrary, this mechanical manipulation may also result in contamination by a vaginal micro-organism and increase the risk of infections or cervical trauma. Additionally, the effect of routine cervical dilatation on patients' perception of pain has not been studied sufficiently yet. As a result, the current literature lacks evidence of cervical dilatation on postoperative pain and is even not all in agreement regarding the potential benefits on overall maternal morbidity.

In this prospective study, our primary aim is to evaluate the effect of intra-operative digital dilatation of cervix on post-operative pain. We hypothesize that dilatation of the cervix as compared with non-dilatation will result in less pain by reducing fluid and blood stasis inside the uterine cavity. Our secondary objective is to assess the maternal morbidity including a reduction in haemoglobin concentrations, puerperal fever, puerperal endometritis and wound infection.
