Postpartum hemorrhage is a leading cause of maternal death globally, and its prevalence is increasing, necessitating innovative therapeutic techniques. Intrauterine balloon devices that use intrauterine vacuum are a potential new technique. This single-center research included all women who had vacuum-induced tamponade utilizing a modified balloon technique. The intrauterine balloon was filled to 50–100 mL and attached to a suction device in order to minimize the uterine size for postpartum hemorrhage management. The etiology of postpartum hemorrhage and time duration of usage were used to determine the success rate of vacuum-induced tamponade, defined as no need for additional interventional therapy. In 66 women, vacuum-induced tamponade was used. Women with uterine atony had an 86 percent success rate, whereas women with postpartum hemorrhage owing to placental pathology had a 73 percent success rate. The success rate improved throughout the course of the research, reaching 100% in women with postpartum haemorrhage owing to uterine atony in the second half of the observation period.
This observational study adds to our pathophysiologic knowledge of uterine atony: in order to cure an atonic uterus, uterine volume must be decreased, resulting in coiling of the uterine spiral arteries and, as a result, less blood loss.
