The postoperative period following cesarean is associated with moderate to severe pain that requires a considerable amount of analgesics that carry with them side-effects such as nausea, vomiting, fatigue and immobilization. Several studies have tried, with variable results, to find a more effective analgesia alternative such as infusion of local anesthetics through a catheter in the surgical wound sinus, a practice that has currently been widely used in clinical practice. Despite existing references on its use in the postoperative period following cesareans there continues to be a lack of information on other aspects. The investigators study hypothesis is that the use of levobupivacaine in the surgical wound will reduce the surface of hyperalgesia compared to the control group.
