PROMab Trial: Ampicillin With or Without Gentamicin for Term Prelabour Rupture of Membranes (PROMab)

25 avril 2026 mis à jour par: Jagdeesh Kaur, Sarawak General Hospital

Term Prelabour Rupture of Membranes Antibiotic Prophylaxis (PROMab) Trial

The goal of this clinical trial is to learn whether adding gentamicin to standard ampicillin prophylaxis can better prevent clinical chorioamnionitis and other maternal and neonatal infectious complications in pregnant women aged 18 years or older with singleton, cephalic, term pregnancies and confirmed prelabour rupture of membranes. The main questions it aims to answer are:

Does ampicillin plus gentamicin reduce the incidence of clinical chorioamnionitis compared with ampicillin alone? Does ampicillin plus gentamicin improve maternal infectious outcomes and neonatal infection-related outcomes compared with ampicillin alone?

Researchers will compare ampicillin alone with ampicillin plus gentamicin to see whether broader antibiotic coverage reduces maternal and neonatal infectious morbidity.

Participants will:

  1. undergo screening and eligibility assessment
  2. provide written informed consent before randomisation
  3. be randomly assigned to receive either intravenous ampicillin alone or intravenous ampicillin plus gentamicin
  4. start study antibiotics at 12 hours after membrane rupture and continue treatment until delivery
  5. undergo routine maternal and fetal monitoring during labour and delivery have maternal and neonatal outcomes assessed during hospital stay and up to 42 days postpartum, including telephone follow-up at Day 14 and Day 42
  6. optionally consent to placental tissue collection for microbiological culture at delivery

Armes et Interventions

Groupe de participants / Bras
Intervention / Traitement
Comparateur actif: Ampicillin Alone
Participants randomized to this arm will receive intravenous ampicillin 2 g stat, followed by intravenous ampicillin 1 g every 4 hours. Study antibiotics will be initiated at 12 hours after prelabour rupture of membranes and continued until delivery. If clinical chorioamnionitis develops, study prophylaxis will be discontinued and therapeutic antibiotics will be started according to local hospital protocol.
Médicament: Ampicillin
Intravenous ampicillin 2 g stat, followed by 1 g every 4 hours, initiated at 12 hours after prelabour rupture of membranes and continued until delivery.
Expérimental: Ampicillin Plus Gentamicin
Participants randomized to this arm will receive intravenous ampicillin 2 g stat, followed by intravenous ampicillin 1 g every 4 hours, plus intravenous gentamicin 5 mg/kg once daily. Study antibiotics will be initiated at 12 hours after prelabour rupture of membranes and continued until delivery. Gentamicin will only be administered to participants with baseline creatinine clearance of 30 mL/min or higher. If clinical chorioamnionitis develops, study prophylaxis will be discontinued and therapeutic antibiotics will be started according to local hospital protocol
Médicament: Ampicillin + gentamicin
Intravenous ampicillin 2 g stat, followed by intravenous ampicillin 1 g every 4 hours, plus intravenous gentamicin 5 mg/kg once daily. Study antibiotics will be initiated at 12 hours after prelabour rupture of membranes and continued until delivery. Gentamicin will only be administered to participants with baseline creatinine clearance of 30 mL/min or higher.
