Cesarean analgesia using levobupivacaine continuous wound infiltration: a randomized trial.

Objective: Neuraxial morphine is considered as a "gold standard" for pain relief after cesarean section, however it causes bothersome side effects. Alternative analgesia including nonsteroidal antiinflammatory drugs (NSAID) has been proposed. We aimed to assess the morphine sparing effect of continuous wound infiltration with a local anesthetic, when added to multimodal systemic analgesia including NSAID without subarachnoid morphine.
