The Labor Progression Study (LaPS): The use of oxytocin augmentation during labor following Zhang's guideline and the WHO partograph in a cluster randomized trial.

Although no significant difference in the proportion of oxytocin augmentation was observed between the two study groups, there were differences in how oxytocin was used. Women in the Zhang group were less likely to be augmented with oxytocin prior to 6 centimeters of cervical dilatation. The duration of augmentation with oxytocin was longer in the Zhang group than in the WHO group. This article is protected by copyright. All rights reserved.
