Epidural analgesia during labor: continuous infusion or patient-controlled administration?

Abstract

Patient-controlled epidural analgesia (PCEA) has several advantages over continuous epidural infusion of bupivacaine during labor: it produces a good analgesia with a limited sensory spread; generally, less bupivacaine is administered and maternal satisfaction with pain control is increased. However, the quality of analgesia is similar to that obtained with other forms of epidural administration. Moreover, PCEA is only a particular form of epidural and, as such, has the same safety requirements. PCEA does not appear to reduce the workload of the anesthetic team. The cost of the PCA pump will need to be included in future evaluation of the cost/benefit ratio.
