Intra-amniotic urea and low-dose prostaglandin E2 for midtrimester termination

Area of Science:

• Obstetrics and Gynecology
• Reproductive Medicine

Background:

• Intra-amniotic urea injections have been used for mid-trimester abortion.
• Prostaglandin E2 (PGE2) is a known agent for inducing labor and abortion.

Purpose of the Study:

• To assess the efficacy and morbidity of a standard urea dose (80 g) combined with a reduced dose of prostaglandin E2 (PGE2) (2-5 mg) for abortion.
• To evaluate the safety and effectiveness of this modified regimen compared to previous protocols.

Main Methods:

• A study involving 110 patients undergoing abortion.
• Administration of 80 g urea and 2-5 mg PGE2.
• Monitoring of abortion induction time, inpatient stay, and complications.

Main Results:

• All 110 patients successfully aborted.
• The mean induction-to-abortion time was 10 hours and 41 minutes.
• The average inpatient stay was 3.3 days, with 4.5% experiencing cervical laceration.

Conclusions:

• The combination of standard-dose urea and a lower dose of PGE2 is an effective method for inducing abortion.
• This regimen appears to offer a favorable balance of efficacy and safety, with a short mean abortion time and hospital stay.
