Evidence from Labour Progression Study (LaPS) and Zhang's new partogram

Labor management is crucial in providing safe delivery care and avoiding the first cesarean section. In 2014, the Obstetrics and Gynecology Branch of Chinese Medical Association updated the guideline on new labor management according to the study results published by Zhang and his colleagues in 2010 based on 62 415 cephalic, singleton pregnant women with spontaneous labor, vaginal delivery and healthy neonatal outcomes. In December 2018, the Labour Progression Study (LaPS), a cluster-randomised controlled trial at 14 obstetric units in Norway, was reported by Bernitz and his colleagues in The Lancet. The primary outcome was the rate of intrapartum caesarean sections (ICSs) in obstetric units using the WHO partograph (control group) or Zhang's partogram (intervention group), which did not show any differences. Here, we discussed the evidence that LaPS provided in reducing the ICSs rate. Key words: Delivery, obstetric; Labor, obstetric
