Summary description of the study

The number of bleeding after childbirth is increasing worldwide, including in industrialized countries. One of the main causes is the occurrence of 'uterine atony' after childbirth. 'Uterine atony' is a lack of or reduced contraction (tightening) of the uterine muscle (uterus = womb). A natural contraction of the uterus after childbirth prevents severe bleeding. In this clinical study at the University Hospital Zurich, we want to investigate the benefit and safety of the preventive (prophylactic) insertion of a bladder catheter into the uterus (to create a vacuum) after a cesarean section. This should prevent severe postpartum bleeding. We plan to include 70 patients who have undergone a cesarean section.

Intervention under investigation

The catheter is inserted into the uterus to create a vacuum. Through the vacuum, the uterus contracts (similar to natural contraction), which should stop the postpartum bleeding. This is a therapeutic approach that has already been applied since 2023 at the University Hospital Zurich for severe bleeding. In this study, we want to investigate whether we can already, at an earlier step, prevent the occurrence of increased bleeding – that is, whether the prophylactic insertion of this catheter can prevent the occurrence of bleeding itself.
