OBJECTIVE: To compare maternal outcomes of uterine balloon tamponade (UBT) versus an intrauterine vacuum-induced hemorrhage control device (VHD) for the management of primary postpartum hemorrhage (PPH).
METHODS: Retrospective cohort of all patients with PPH due to uterine atony treated with an intrauterine device within a university health system from January 2019 to June 2021. The primary outcome of massive transfusion, defined as PPH requiring transfusion of ≥4 units of packed red blood cells (PRBC), was compared between 2 groups: UBT (n = 78) versus VHD (n = 36). Statistical analysis included the use of chi-squared and Wilcoxon rank sum tests with statistical significance set at P < 0.05.
RESULTS: Baseline characteristics were similar between the 2 groups. The proportion of patients who received ≥4 units of PRBC was significantly lower in the VHD group compared to the UBT group (2.8% vs. 20.5%, P = <0.01). The proportion of patients who were transfused ≥2 units of PRBC and median estimated blood loss (EBL) were also both significantly lower in the VHD group compared to the UBT group (36.1% vs. 57.7%, P = < 0.01, and 1 500 mL vs. 1 875 mL, P = 0.02, respectively). Rates of other secondary outcomes were similar between the 2 groups.
CONCLUSION: Our data suggest that the use of intrauterine VHD in the management of PPH is associated with a lower number of massive transfusions and EBL compared to UBT. Randomized controlled trials are needed before drawing definitive conclusions on which device is more effective in this setting.
