Abstract
Background: Induction of labour is a common obstetric procedure which is performed for a variety of medical and non-medical indications.
Aim of the Work: To study the effect of intravenous Dexamethasone on the interval between labor induction and the start of the active phase and the duration of the active phase in post term primigravid women.
Patients and Methods: After ethical committee approval and informed consent from the patients, this double blinded randomized, controlled study was conducted at tertiary care hospital at Ain Shams University Maternity Hospital from January 2022 till October 2022 and performed on total of 102 Primigravid post term pregnant women who underwent induction of labour.
Results: Our study results revealed that duration of first stage and second stage of labor were statistically shorter in Dexamethasone group that in Control group while duration of third stage of labor was statistically non-significantly different between Dexamethasone group and control group.
Conclusion: Intravenous injection of 8 mg of dexamethasone appears to shorten labor duration and has the ability to improve the ripening of cervix and acceleration of labor induction by shortening the duration intervals between labor induction initiation and starting of active labor phase, as well as shortening time of the first and second stages of labor with no difference in maternal or fetal adverse effects.
