Comparison of Nifedipine and Isoxsuprine to Cervical Length in Threatened Preterm Labor

Objective: This study aimed to determine differences in cervical length changes between administration of nifedipine and isoxsuprine. Method: Subjects of the study were pregnant women who meet the inclusion criteria (n=16). Treatments were given for 48 hours. Parameters measured was the cervical length before and after the administration of nifedipine and isoxsuprine. This study was conducted in Dr. Hasan Sadikin General Hospital from January until April 2020. Result: Less shortening of the cervical length after administration of tocolytic isoxsuprin for 48 hours compared with tocolytic nifedipine and statistically significant with p value of 0.0001 (p<0.05) using Paired T tests. Conclusion: Isoxsuprin is more effective to prevent shortening of the cervical length compared to nifedipine in cases of threatened preterm labor. Key word: Nifedipine, Isoxsuprine, cervical length, threatened preterm labor
