Amnioinfusion for preventing puerperal infection. A prospective study

Area of Science:

• Obstetrics and Gynecology
• Infectious Disease Prevention
• Maternal Health

Background:

• Prolonged rupture of membranes increases the risk of maternal puerperal infection.
• Current management strategies may not fully mitigate infection risk in high-risk pregnancies.

Purpose of the Study:

• To investigate the efficacy of amnioinfusion in reducing puerperal infection among women with ruptured membranes exceeding six hours.
• To evaluate amnioinfusion as a potential preventative measure against chorioamnionitis and endometritis.

Main Methods:

• A prospective randomized study involving 68 women across three teaching institutions.
• Participants were assigned to either amnioinfusion or routine care.
• Amnioinfusion involved a bolus and continuous drip via internal uterine pressure catheters.

Main Results:

• The amnioinfusion group (n=36) experienced significantly lower rates of puerperal infection (9/36) compared to the control group (n=32, 16/32; P < .033).
• No significant differences were observed in labor duration, membrane rupture time, or delivery methods between groups.
• No neonatal sepsis or amnioinfusion-related complications were reported.

Conclusions:

• Amnioinfusion is a safe and cost-effective technique for decreasing puerperal infection incidence in high-risk women.
• This intervention shows promise in improving maternal outcomes in cases of prolonged ruptured membranes.
