Impact of the introduction of a low-cost uterine balloon tamponade (ESM-UBT) device for managing severe postpartum hemorrhage in India: A comparative before-and-after study

OBJECTIVE

To evaluate the impact of introducing a uterine balloon tamponade (ESM-UBT) device for managing severe postpartum hemorrhage (PPH), mainly due to uterine atony, in health facilities in India on the rates of PPH-related maternal death and invasive procedures for PPH control.

METHODS

We used a quasi-experimental, difference-in-difference (DID) design to compare changes in the rates of a composite outcome (PPH-related maternal death and/or artery ligation, uterine compression sutures, or hysterectomy) among women delivering in nine intervention facilities compared with those delivering in two control facilities, before and after the introduction of ESM-UBT.

RESULTS

The study sample included 214 123 deliveries (n = 78 509 before ESM-UBT introduction; n = 47 211 during ESM-UBT introduction; and n = 88 403 after ESM-UBT introduction). After introduction of ESM-UBT, there was a significant decline in the rate of the primary composite outcome in intervention facilities (21.0-11.4 per 10 000 deliveries; difference -9.6, 95% confidence interval -14.0 to -5.4). Change in the rate of the primary composite outcome was not significant in control facilities (11.7-17.2 per 10 000 deliveries; difference 5.4, 95% confidence interval -3.9 to 14.9). DID analyses showed there was a significant reduction in the rate of the primary composite outcome in intervention facilities relative to control facilities (adjusted DID estimate -15.0 per 10 000 points, 95% confidence interval -23.3 to -6.8; P = 0.005).

CONCLUSION

Introduction of the ESM-UBT in health facilities in India was associated with a significant reduction in PPH-related maternal death and/or invasive procedures for PPH control.

Uterine compression sutures with additional hemostatic procedures for the management of postpartum hemorrhage

AIM

The aim of the study was to evaluate the efficacies and possible short-term complications in women receiving uterine compression sutures only and those with additional hemostatic procedures for the management of postpartum hemorrhage.

METHODS

It was a retrospective study carried out from year 2009 to 2019 at a tertiary obstetric hospital and included 79 women who underwent uterine compression sutures (B-Lynch sutures, Hayman's sutures and Cho's sutures) for primary postpartum hemorrhage. Thirty-six of these women had additional hemostatic procedures (uterine artery ligation or embolization) performed for bleeding control.

RESULTS

Of the 43 women who were primarily treated with uterine compression sutures only, the success rate to preserve the uterus was 97.7% (42/43). In women with uterine compression sutures and additional hemostatic procedures performed, the success rate was 75% (27/36). Among these two groups of women without peripartum hysterectomy, there were no significant differences in the incidence of secondary postpartum hemorrhage (14.8% vs. 11.9%; P = 0.729), postoperative endometritis (14.8% vs. 14.3%; P > 0.99) and retained products of conception (3.7% vs. 9.5%; P = 0.641) during their 6-week postpartum checkup. Three women were diagnosed to have hematometra. No pyometra or uterine necrosis was noted.

CONCLUSION

Uterine compression sutures with additional hemostatic procedures are effective to control postpartum hemorrhage and prevent hysterectomy. The short-term complication rate is low. Long-term monitoring is needed to identify rare but potentially dangerous complications.

Maternal outcomes following massive obstetric haemorrhage in an inner-city maternity unit

This retrospective study evaluates the effects of a massive postpartum haemorrhage (PPH) on maternal outcomes in an inner-city London hospital. One hundred and eighty-four cases of a massive primary PPH (>2000 mL) were identified over a seven-year period. A sub-group analysis was performed to assess whether 2000-3000 mL blood loss (134 cases) was associated with specific maternal characteristics or reduced adverse outcomes compared with >3000 mL blood loss (50 cases). Bakri balloon tamponade (BBT) was the most frequent form of surgical management in both groups (21 vs. 46%), followed by compression sutures (16.4 vs. 24%), the 'uterine sandwich' technique (6.7 vs. 14%) and the hysterectomy (0 vs. 4%). There were significant differences between these groups in placenta praevia as the cause of blood loss (8 vs. 22%, p = .01), length of stay (4.6 vs. 5.9 d, p = .02), use of BBT (p = <.01) and hysterectomy (p = .03). PPH is associated with premature maternal morbidity and mortality. The incidence is increasing in high income countries despite various guidelines, skills training and identification of risk factors. A prediction and assessment of blood loss remain the very cornerstone for a prompt, effective management. Our study shows that the morbidity is clearly related to the amount of blood loss and highlights the existing variable practices for the management of PPH. Impact statement What is already known on this subject? A postpartum haemorrhage (PPH) remains a common cause of maternal morbidity and mortality. Massive PPH (>2000 mL) rates continue to rise in developed countries. The management of PPH includes the medical treatment followed by surgical methods including the Bakri balloon tamponade (BBT), compression sutures or a hysterectomy. What do the results of this study add? This retrospective study evaluates the effects of a massive PPH (blood loss >2000 mL) on maternal outcomes. One hundred and eighty-four cases of a massive PPH were identified over a seven-year period. Sub-group analysis was performed to assess whether a 2000-3000 mL blood loss was associated with specific maternal characteristics and differences in obstetric practice compared with a >3000 mL blood loss. There were significant differences between these groups in placenta praevia, as the cause of blood loss, the length of stay, the use of BBT and the hysterectomy rates. What are the implications of these findings for clinical practice and/or further research? An early identification of the risk factors of a massive PPH is essential to improve maternal outcomes and is an important part of the antenatal, intrapartum and postpartum period. The prediction and assessment of blood loss remain key for a prompt, effective management. The amount of blood loss is related to adverse maternal outcomes and the management techniques applied. BBT has an essential role to play and should be included as part of the core training in the management of a PPH.

Towel Uterus Model for Uterine Compression Sutures Technical Skills Training: A Review of Literature and Development of a Performance Rubric

Postpartum hemorrhage (PPH) continues to be the leading cause of maternal mortality worldwide, occurring in about five percent of deliveries. The most common cause of PPH is uterine atony, and a number of medical and surgical management techniques are available to prevent morbidity and mortality associated with PPH in this context. Uterine compression sutures provide a more conservative surgical approach, allowing for the preservation of fertility. Obstetrics and Gynecology (Ob/Gyn) residents need to be adequately trained to competently perform this technique. The goal of this surgical skills training is for Ob/Gyn residents to be able to surgically manage PPH using uterine compression sutures. A uterine towel model for surgical skills training in the use of uterine compression sutures was developed. The simulator is explained and compared to similar models. Possible ways to implement and use the simulator in a simulation curriculum are also described. A performance-based assessment rubric was also developed in order to formatively aid with the learning and understanding of the technique. Much work is still needed to test the validity and reliability of this tool, but based on current literature, results may be promising.

Uterine compression sutures as an effective treatment for postpartum hemorrhage: case series

We evaluated the role of uterine compression sutures as a conservative treatment for postpartum hemorrhage (PPH) after failed medical treatment. We retrospectively reviewed the charts of all patients who delivered between 2003 and 2009 at a single tertiary care center and who underwent uterine compression sutures for PPH. Twelve women had uterine compression sutures for PPH. The mean age of the patients was 36.3 ± 5.2 years. The mean gestational age at delivery was 37.7 ± 2.0 weeks, and the average estimated blood loss was 2.1 ± 1.1 L. The mean procedure time to perform the uterine compression sutures was 9.3 ± 2.8 minutes. The success rate of compression sutures was 92% with only one failure resulting in a hysterectomy. Uterine compression sutures are an effective method for the treatment of PPH, thus avoiding hysterectomy and preserving potential fertility.
