Postpartum Hemorrhage, ImmediateNCT04467996
Minimum Effective Duration of Intrauterine Balloon Tamponade for the Management of Postpartum Hemorrhage
A study testing Intrauterine balloon tamponade in people with Postpartum Hemorrhage, Immediate, run by Denver Health and Hospital Authority at 1 site in United States.
Trial summary
Intrauterine balloon tamponade (IUBT) is recommended worldwide as the second-line therapy to treat postpartum hemorrhage. While much literature demonstrates the effectiveness of this therapy, little is known about how long the IUBT should be used once placed. Read more about this study

About this study
Official title: Evaluation of the Minimum Effective Duration of Intrauterine Balloon Tamponade for the Management of Postpartum Hemorrhage: A Randomized Controlled Trial
Intrauterine balloon tamponade (IUBT) is recommended worldwide as the second-line therapy to treat postpartum hemorrhage. While much literature demonstrates the effectiveness of this therapy, little is known about how long the IUBT should be used once placed. Though it is common to use IUBT for 12-24 hours, the balloon may be equally effective when used for shorter durations of time, which could have beneficial effects for patients and hospitals. The proposed study is a pragmatic randomized controlled trial of non-inferiority comparing two durations of time for intrauterine balloon tamponade placement, 6 and 18 hours, in controlling postpartum hemorrhage.
The specific aims of the proposed study are to determine: 1) whether quantitative blood loss significantly differs when the balloon is removed in 6 hours compared to 18 hours, 2) whether hemorrhage-related morbidity differs when the IUBT is kept in place for 6 or 18 hours, and 3) whether shorter duration of IUBT placement has beneficial effects including shortened postpartum hospital stays, improved maternal-infant bonding, and reduced postpartum pain prior to maternal discharge from hospital.
We hypothesize that, once hemorrhage control has been achieved with IUBT placement, there is no clinically significant difference in postpartum blood loss when the balloon is removed 6 hours after placement compared to 18 hours after placement.

| 18 hour IUBT placement | Active comparator | Not described Receives: Device: Intrauterine balloon tamponade |
What is being measured
The primary outcome is the main question the study is designed to answer.
Quantitative blood loss
total blood loss includes output from the intrauterine balloon plus blood loss from sanitary pads
Measured: 18 hours

Postpartum hemorrhage related outcomes
return to the OR, replacement of the IUBT, hysterectomy, pelvic artery embolization
Measured: during admission
Hematocrit
change in hematocrit from admission to discharge
Measured: during admission
Postpartum length of stay
Length of stay in hours
Measured: during admission
Endometritis
diagnosed postpartum
Measured: during admission
Chorioamnionitis
requiring more than one dose of antibiotics postpartum
Measured: during admission
Transfusion of packed red blood cells
after IUBT placement
Measured: during admission
Maternal-infant bonding
measured by the mother-to-infant bonding scale (MIBS), scale 0-27, higher score indicates worse maternal-infant bonding
Measured: during admission
Maternal pain
measured by the visual analogue scale (VAS), scale 0-10, higher score indicates worse pain
Measured: during admission

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Intrauterine balloon tamponade (IUBT) is recommended worldwide as the second-line therapy to treat postpartum hemorrhage. While much literature demonstrates the effectiveness of this therapy, little is known about how long the IUBT should be used once placed. Though it is common to use IUBT for 12-24 hours, the balloon may be equally effective when used for shorter durations of time, which could have beneficial effects for patients and hospitals. The proposed study is a pragmatic randomized controlled trial of non-inferiority comparing two durations of time for intrauterine balloon tamponade placement, 6 and 18 hours, in controlling postpartum hemorrhage.
The specific aims of the proposed study are to determine: 1) whether quantitative blood loss significantly differs when the balloon is removed in 6 hours compared to 18 hours, 2) whether hemorrhage-related morbidity differs when the IUBT is kept in place for 6 or 18 hours, and 3) whether shorter duration of IUBT placement has beneficial effects including shortened postpartum hospital stays, improved maternal-infant bonding, and reduced postpartum pain prior to maternal discharge from hospital.
We hypothesize that, once hemorrhage control has been achieved with IUBT placement, there is no clinically significant difference in postpartum blood loss when the balloon is removed 6 hours after placement compared to 18 hours after placement.
