[Second trimester pregnancy termination with and without prostaglandins]

Area of Science:

• Obstetrics and Gynecology
• Reproductive Medicine

Background:

• Second-trimester pregnancy termination is a critical aspect of reproductive healthcare.
• Various methods exist, each with potential benefits and drawbacks regarding efficacy and patient outcomes.

Purpose of the Study:

• To compare the effectiveness of three second-trimester pregnancy termination methods.
• To evaluate the impact of pre-treatment with prostaglandins on extra-amniotic balloon-catheter termination.

Main Methods:

• Retrospective analysis of 34 cases using intra-amniotic saline instillation.
• Retrospective analysis of 19 cases using extra-amniotic balloon-catheter with oxytocin.
• Prospective comparison with 13 cases using extra-amniotic balloon-catheter preceded by intracervical prostaglandin E2 (Prostin E2).

Main Results:

• In nulliparous patients, prostaglandin pre-treatment did not reduce abortion time or improve success rates.
• In parous patients, prostaglandin pre-treatment significantly reduced abortion time.
• No instances of failed or prolonged abortions were recorded in the prostaglandin pre-treatment group.

Conclusions:

• Cervical treatment with a single dose of prostaglandin E2 is effective in reducing abortion time for parous patients undergoing second-trimester termination via extra-amniotic balloon-catheter.
• The benefit was not observed in nulliparous patients, suggesting parity influences treatment response.
• All methods evaluated showed no failed or prolonged abortions in the studied groups.
