Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The study aims to compare maternal and early neonatal outcomes of abdominal disimpaction with lower uterine segment support in comparison to the classic "push" method for delivery of impacted fetal head during Cesarean section for obstructed labor.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Obstructed labor refers to failure of labor progress in spite of good uterine contractions and is attributed to mismatch between the size of the presenting part of the fetus and the mother's pelvis. Approximately 8% of maternal deaths worldwide are attributed to obstructed labor and subsequent puerperal infection, uterine rupture, and postpartum hemorrhage.

In these situations, Cesarean section could minimize maternal and neonatal morbidity. However, Cesarean section is challenging when the head is deeply impacted and is associated with high risk of maternal injuries and perinatal injuries. The most common complication is extension of uterine incision which could involve the vagina, bladder, ureters and broad ligament. Neonates are also at risk of skull fractures, cephalhematoma, and subgaleal hematoma mainly due to manipulations. Currently, the most popular approaches for fetal head delivery are the push and pull methods. Although push method seems to be more convenient and does not necessitate extensive experience, it is more significantly associated with extension than the pull method. Although pull method seems to be more safe, it is more difficult to perform and usually warrants an aggressive uterine incision to deliver the fetus. In 2013, investigators published a case series on abdominal disimpaction with lower uterine segment support which basically allows obstetricians to deliver the fetal head through a transverse uterine incision with minimal risk of extensions and neonatal complications. In this study, investigators aim to validate this approach in comparison to the classic push method.

Disimpaction with lower uterine support

Cesarean section with support of the lower uterine segment

Group Type EXPERIMENTAL

Cesarean section

Intervention Type PROCEDURE

Abdominal disimpaction with lower uterine segment support: the edge of the lower uterine segment is grasped by 3-4 modified Allies forceps (with broader jaws) applied along the lower edge of the incision until it is completely supported. These forceps are handled by the assistant, and gentle traction is applied upward, perpendicular to the uterine surface and away from the fetal head without excessive force. Accordingly, the hand of the surgeon could be inserted into the uterine cavity, and adequate space for manipulations is available without applying pressure on the lower segment. The fetal head is eventually grasped and delivered.
