Clinical TrialParacervical block--a viable alternative for labor pain relief?
Two hundred and forty-eight consecutive deliveries with a 0.25% bupivacaine paracervical block (PCB) using a superficial injection technique were studied prospectively during the progress of labor in the three month study period. Parturients with signs of fetal distress were excluded. Pain level and the maternal, fetal and neonatal effects related to PCB were evaluated. ⋯ PCB in selected parturients with a low-dose superficial technique has been shown to be an effective analgesic modality with minimal fetal and neonatal side-effects, but post-blockade fetal bradycardia cannot be wholly eliminated.
