Summary

Prostaglandin E2 (PGE2) gel was more effective than hygroscopic dilators for cervical ripening and labor induction. PGE2 gel also led to fewer maternal and neonatal infections, despite higher initial costs.

Area of Science:

  • Obstetrics and Gynecology
  • Reproductive Medicine

Background:

  • Cervical ripening is crucial for successful labor induction in term pregnancies with unfavorable cervical scores.
  • Comparing different pre-induction cervical ripening methods is essential for optimizing obstetric outcomes.

Purpose of the Study:

  • To compare the efficacy and safety of intracervical prostaglandin E2 (PGE2) gel versus hygroscopic dilators for pre-induction cervical ripening.
  • To evaluate the impact of these methods on labor induction success and maternal/neonatal outcomes.

Main Methods:

  • A randomized clinical trial involving 441 women at term with unfavorable cervical scores.
  • Comparison of a single intracervical PGE2 gel application against a single insertion of hygroscopic dilators.
  • Induction success defined as entry into active labor within 6 hours of oxytocin infusion.

Main Results:

  • No significant difference in pre- or post-ripening cervical scores between the two groups.
  • PGE2 gel group showed a higher rate of induction success (45%) compared to hygroscopic dilators (28%).
  • Hygroscopic dilators were associated with increased rates of postpartum endometritis and suspected neonatal infection.

Conclusions:

  • While cervical score changes were similar, PGE2 gel demonstrated superior performance in achieving successful labor induction.
  • Hygroscopic dilators led to a higher incidence of maternal and neonatal infections, potentially due to longer labor durations.
  • Despite higher initial costs, PGE2 gel may offer better overall value due to improved outcomes and reduced complication rates.
