Abstract

Aim: The aim of the study was to evaluate the effectiveness of nifedipine in inhibiting preterm labor.

Study design:A Quasi-experimental study.

Place and duration: The study was conducted at the Department of obstetrics & Gynecology

Dr Sulaiman Al-Habib Hospital, Buraidah Al-Qassim Saudi Arabia for one-year duration from April 2019 to April 2020.

Methodology:75 single pregnancies with preterm labor between 28 and 34weeks of pregnancy were selected. A patient with preterm labor, dilation of the cervix <3 cm and an intact membrane was enrolled in the study. Nifedipine was used as a tocolytic agent.

Results: While effective tocolysis was achieved in 73.33% (55/75) of patients, tocolysis was not achieved in the remaining 27.7% (20/75).

Conclusion: Nifedipine successfully inhibited uterine contractions and delayed labor by> 48 hours; sufficient time for an intrauterine or corticosteroid transfer effect.

Key words: Preterm labor, Tocolysis, Nifedipine.
