Patient-controlled epidural analgesia or continuous infusion: advantages and disadvantages of different modes of delivering epidural analgesia for labour.
Patient-controlled epidural analgesia, intermittent top-up and continuous infusion are equally effective in providing epidural pain relief during labour. Patient-controlled epidural analgesia is associated with a significant reduction in hourly dose requirements when compared with continuous infusion, and by transferring the responsibility for epidural top-up, it offers the parturient the psychological benefit of being in control. For these reasons, patient-controlled epidural analgesia may become the method of choice for epidural pain relief during labour. However, the safety of the method needs to be documented more extensively, and the advantage of a reduction in hourly dose requirements needs to be visualized in terms of an improvement in labour or neonatal outcome. Moreover, the optimal dose, drug combination and settings still remain to be determined.
