Oxytocin induction of labor: a comparison of 20‐ and 60‐min dose increment levels

Abstract
Objectives: To compare the efficacy and complications of oxytocin dose increments at 20‐ and 60‐min intervals for induction of labor in women with low parity. Methods: One hundred women of low parity requiring induction of labor were randomly allocated to 20‐ and 60‐min oxytocin dose increments, 50 patients in each group. The basal oxytocin dose was 1 milliunit/min and doubling of the oxytocin dose was done at intervals of 20 and 60 min. Results: The group with 60‐min increments had a decreased incidence of uterine hyperstimulation, cesarean section and operative vaginal delivery. The induction‐delivery interval was similar in both groups. Conclusion: The oxytocin infusion regimen with increments at 60‐min intervals is safer than and equally effective as 20‐min incremental intervals.
