La phase de latence : déterminants de son respect et issues materno-foetales

Abstract : Objective: To evaluate the maternal and neonatal outcomes associated with the respect of the latent phase and the determinants which influence the management of a non-progressive labor before 6 centimeters. Among low risk nulliparous women with spontaneous onset of labor, comparison of the maternal and neonatal outcomes with or without latent phase respect. Methods: unicenter retrospective study of the non-exposed/exposed type realized at Port-Royal from 09/01/2014 to 08/31/2015. The exposed group "respecting latent phase", defined by the absence of intervention (amniotomy or oxytocin), and the non-exposed group defined as patients who had no intervention (amniotomy or oxytocin), following more than 2 hours of non-progressive labor. Results: The study population consisted of 247 patients, including 114 in the exposed group and 133 in the not exposed group. The results obtained with this study showed that the respect of the latent phase seems to be associated with a reduction in the rate of instrumental deliveries or with maneuver or cesarean delivery (36,1% versus 18,4% avec p=0, 0003), a reduction in the rate of Postpartum haemorrhage (14,3% vs 5,3% p = 0,015) and a minor rate of neonatal resuscitation. Conclusion: These results suggest that compliance with the latent phase would have beneficial effects on labor and would not be significantly associated with increased maternal and neonatal risks. This encourages the setting up of additional research.
