What You Need to Know Before You Apply

What is the purpose of this trial?

The purpose of this study is to decrease the likelihood of composite postpartum hemorrhage (PPH) morbidity, which consists of i) Estimated or quantified blood loss of 1,500 mL or more, ii) transfusion of any blood products or iii) hysterectomy

Do I need to stop my current medications for the trial?

The trial information does not specify whether you need to stop taking your current medications.

Is amnioinfusion generally safe for humans?

Amnioinfusion is generally considered safe with few adverse effects, as studies have shown no complications related to the procedure and it is described as a simple and safe treatment.12345

How does the treatment Prophylactic Amnioinfusion for Postpartum Hemorrhage differ from other treatments?

Prophylactic Amnioinfusion is unique because it involves introducing fluid into the uterus during labor to manage complications like meconium (a newborn's first stool) and low amniotic fluid levels, which can help reduce fetal distress and improve outcomes. This method is considered safe and effective, with fewer adverse effects compared to other treatments.13678

What data supports the effectiveness of the treatment Prophylactic Amnioinfusion for Postpartum Hemorrhage?

Research on prophylactic amnioinfusion in women with low amniotic fluid during labor shows it can reduce the need for cesarean sections and other interventions, suggesting it helps improve outcomes during childbirth. This indicates that amnioinfusion may be beneficial in managing complications, although its direct effectiveness for postpartum hemorrhage is not specifically studied.6791011

Published Research Related to This Trial

In a study of 305 patients with oligohydramnios, prophylactic amnioinfusion significantly reduced the need for operative interventions due to fetal distress and lowered the cesarean section rate, indicating its efficacy in improving labor outcomes.
Patients who received amnioinfusion also had higher umbilical artery pH levels at delivery and shorter hospital stays, suggesting that this intervention can enhance fetal well-being without increasing the risk of complications like amnionitis or endometritis.
Prophylactic amnioinfusion as a treatment for oligohydramnios in laboring patients: a prospective, randomized trial.Schrimmer, DB., Macri, CJ., Paul, RH.[2019]
Two cases of fatal amniotic fluid embolism occurred in women who underwent saline amnioinfusion during labor, particularly after thick meconium staining was observed, raising concerns about the safety of this intervention in such situations.
While amniotic fluid embolism is rare, the cases suggest a potential link between amnioinfusion and increased risk, especially in the presence of rapid labor and meconium-stained fluid, warranting further investigation without immediate changes to clinical practice.

A survey of 78 academic obstetrics and gynecology departments in the U.S. revealed that amnioinfusion is performed with a variety of protocols and is associated with few complications, indicating its relative safety.
The study found no significant relationship between the method of amnioinfusion or the number of procedures performed and the incidence of complications, suggesting that amnioinfusion can be safely implemented across different practices.
