In this study, two parturients receiving CIPCEA experienced breakthrough pain, which occurred about three hours after initiation of CSE, at 3 cm and 5 cm cervical dilatation respectively.
Exclusion criteria included any fetal or maternal indications for necessary termination of pregnancy, multiple pregnancy, preterm rupture of membranes (PROM), fetal anomalies, cervical dilatation equal or greater than 5 cm, treatment with other tocolytic agents 24 hr before delivery, previous cesarean delivery, susceptibility to nitroglycerin compounds or any contraindication of Nitro compounds and evidence of chorioamnionitis (maternal fever, leukocytosis, fetal tachycardia), maternal heart disease, placenta previa or vasa previa, vaginal bleeding except the minor bleeding caused by initial dilatation of the cervix (bloody show).

The women were randomly assigned in a 1:1 ratio to nonblinded management with either early amniotomy (defined as artificial rupture of membranes performed when cervical dilatation was equal to or less than 4 cm) or standard care (defined as artificial rupture of membranes performed when cervical dilatation was greater than 4 cm).
We then performed separate univariate logistic regression analyses by computing the presence of RBP as the dependent variable and maternal Body Mass Index (BMI), cervical dilatation at point of epidural placement, pre-block use of oxytocin, pre-block pain scores, intervertebral level of epidural placement, position of parturient during procedure (lateral or sitting), loss of resistance technique (air or saline), type of intrathecal local anaesthetic used for induction of analgesia, depth of the epidural catheter in space, type of epidural local anaesthetic used for maintenance of analgesia and neonatal birth weight as independent variables.
