Uterine Balloon Tamponade under Ultrasound Guidance in Women with Postpartum Hemorrhage: A Retrospective Cohort Study

Background: Postpartum hemorrhage (PPH) represents one of the principal causes of maternal mortality and morbidity worldwide. Uterine balloon tamponade (UBT) is recommended for the treatment of postpartum hemorrhage due to uterine atony in women who do not respond to pharmacological first-line treatment. The success of UBT in bleeding control is related to the correct positioning of the device, since incorrect insertion can be associated with ineffectiveness and requires time-consuming repositioning maneuvers, with a further increase in blood loss. The use of ultrasound (US) during UBT may increase the success rate by preventing wrong positioning. This study aims to demonstrate the role of US guidance during UBT and to assess whether US guidance can ease positioning and reduce insertion times, preventing additional repositioning maneuvers, in comparison with a US check carried out after balloon insertion. Methods: This was a retrospective study including 370 women who underwent vaginal delivery, had PPH caused by uterine atony and required UBT at Sant'Anna Hospital from 2015 to 2019. The exclusion criteria were an abnormal placental site, vaginal or cervical trauma, coagulation defects, uterine anomalies, previous postpartum hemorrhage and previous caesarean section. Included subjects were divided into two groups: the US-guided group (n = 200) underwent Bakri balloon positioning under US guidance, and the non-guided group (n = 170) received a US check only after balloon insertion. The primary outcome was the success rate of the procedure, expressed as the percentage of cases with bleeding control without the need for balloon repositioning; the secondary outcomes were the length of the procedure and some parameters related to blood loss. Results: The success rate was 99% for the US-guided group vs. 86% for the non-guided group. None of the patients required hysterectomy. In the US-guided group with respect to the non-guided group, we observed a significant reduction in blood loss (1100 ± 450 vs. 1500 ± 600 mL; p < 0.001), Δhemoglobin level (1.8 ± 1.1 vs. 2.7 ± 2.0 g/dL, p < 0.001) and time required for the procedure (8 vs. 13 min, p < 0.001). Conclusions: Our data suggest that the use of US guidance for placement of UBT was associated with reduced need for balloon repositioning, lower blood loss, and faster resolution of postpartum hemorrhage.

Intraoperative Ultrasound in the Management of Placenta Accreta Spectrum: Waste of Time or Valuable Step

Placenta accreta spectrum (PAS) is increasing worldwide paralleling the rising surge of the cesarean section rate. It is well known that sonographic screening for PAS in the second trimester in high-risk patients can predict and reduce major intraoperative hemorrhage during a cesarean hysterectomy. We report the importance of intraoperative ultrasound in the management PAS disorders. It has a crucial role in the reassessment of the placenta location and invasion, reconsidering the cesarean hysterectomy, localization of the hysterotomy, the bladder dissection, and in the conservative treatment. Workshops and hands-on training in intraoperative ultrasound among surgeons must be supported.
