Randomized Controlled Trial Multicenter Study Clinical TrialRisk factors for difficult delivery in nulliparas with epidural analgesia in second stage of labor.
To identify risk factors for difficult delivery among nulliparas in the second stage of labor with continuous epidural analgesia, and to develop a multivariable model that is predictive of difficult delivery. ⋯ Our observations concerning maternal characteristics and obstetric variables are consistent with previous observations with the exception of time of induction of the epidural. The predictive model may be useful in defining high-risk populations for subsequent intervention studies designed to assess approaches to reduce difficult delivery.
