Bakri balloon - A cautionary tale

Prevention of intrauterine balloon displacement in patients with postpartum hemorrhage: A narrative review

Postpartum hemorrhage (PPH) remains a significant complication of pregnancy globally, with uterine atony accounting for the great majority of cases. Second-line hemostatic strategies such as uterine balloon tamponade play a crucial role in managing refractory hemorrhage. Despite its effectiveness, the phenomenon of balloon displacement poses a challenge to PPH management, often leading to treatment failure. Various techniques have been proposed to address this issue, including vaginal packing, cervical cerclage, fixation to the abdominal wall, holding the cervix with ring forceps, and suspending the balloon with cervical sutures. Each method has its advantages and limitations, influencing its suitability in different clinical scenarios. Understanding these techniques may be useful to optimize and improve the management of PPH and maternal outcomes. This review provides a comprehensive summary of these strategies, their mechanisms, and their clinical implications, aiming to guide healthcare providers in choosing the most appropriate approach for individual cases of PPH.

Efficacy of Intra-Uterine Tamponade Balloon in Post-Partum Hemorrhage after Cesarean Delivery: An Impact Study

Invasive therapies (surgery or radiological embolization) are used to control severe post-partum hemorrhage. The intra-uterine tamponade balloon is a potential alternative, well documented after vaginal delivery. However, available data on its use after cesarean delivery remain scarce. This study assessed the efficacy of the intra-uterine tamponade balloon during post-partum hemorrhage in a cesarean delivery setting. Using a retrospective impact design, post-partum hemorrhage-related outcomes before (“pre-balloon” period) versus after implementation of intra-uterine tamponade balloon (“post-balloon” period) were compared. All women with post-partum hemorrhage requiring potent uterotonic treatment with prostaglandins after cesarean delivery over a 9-year period were eligible. The primary outcome was the rate of invasive procedure (conservative surgery, radiological embolization and/or hysterectomy). p < 0.05 was considered statistically significant. A total of 279 patients were included (140 vs. 139). Most baseline characteristics were comparable between the two studied periods. The success rate of the intra-uterine tamponade balloon was 82%, and no related complications occurred. Rates of invasive procedures and transfusion were significantly reduced (28.6% vs. 11.5%, p < 0.001 and 44.3% vs. 28.1%, p = 0.006 respectively) during the “post-balloon” period, and length of hospital stay was shorter (p < 0.001). Implementation of intra-uterine tamponade balloon during post-partum hemorrhage after cesarean delivery appears to be safe and effective, with a decrease in both invasive procedures and transfusion rates.

Intrauterine double-balloon tamponade vs gauze packing in the management of placenta previa: A multicentre randomized controlled trial

BACKGROUND

To evaluate the effectiveness and safety of a newly designed intrauterine double-balloon catheter to arrest postpartum hemorrhage (PPH) following cesarean delivery (CD) for placenta previa.

METHODS

We conducted an open-label, multicenter randomized controlled trial in two referral centers and one general hospital. Women with continuous bleeding after placental delivery following CD for placenta previa, who failed to respond to uterotonics, suturing and uterine devascularization, and in the absence of suspected deeply invasive accreta were eligible subjects. Eligible subjects were randomized to receive intrauterine double-balloon catheter (n = 102) or gauze packing (n = 102). The main outcome was the rate of successful hemostasis without the need for additional surgical interventions. The secondary outcomes included the volume of blood loss during and after CD, the rate of PPH, incidence and amount of blood transfusion, hysterectomy, surgical complications, intensive care unit admission, need for re-laparotomy, length of hospital stay, and readmission.

RESULTS

The 224 participants were recruited before delivery, with 20 excluded (14 cases bleeding stopped after uterotonics and/or local myometrium sutures and 6 patients with placental increta). Finally, 102 women were assigned in catheter group and 102 others in gauze group. There was no difference in the rate of successful hemostasis in the catheter and gauze groups (93.1% vs 91.2%, P = .80). Compared with those in the gauze group, women in the catheter group showed significantly less blood loss within 24 hours postpartum (895 [612.3-1297.8] vs 1156 [882.5-1453.3] ml, P < .01), lower rate of PPH ≥1000 ml (42.2% vs 63.7%, P < .01). Accordingly, women in the catheter group had significantly less maternal adverse events such as postpartum anemia, puerperal morbidity, and postpartum pain.

CONCLUSION

Uterine tamponade using a double-balloon catheter was as effective as gauze packing in hemostasis, and appeared to be superior in reducing postpartum blood loss and pain following CD for placenta previa. Using double-balloon catheter in managing PPH in this situation may be a preferable alternative to minimize maternal morbidity.
