Methods The investigators plan to randomize about 150 women undergoing primary and repeat cesarean deliveries to intra-abdominal chloroprocaine versus placebo prior to abdominal closure. Women will be excluded if they have ascertained or presumptive hypersensitivity to the ester type and major anesthetics; if they have chronic pelvic pain or if they refuse to participate in the study. The investigators' primary outcome measure will be postoperative pain as measured by visual analogue scale (VAS) at 1 hour after skin closure. Secondary outcomes will include objective pain as measured by VAS at 2, 6, 24 and 48 hours at rest and during mobilization, adverse effects of chloroprocaine (gastrointestinal side effects, pruritus), concomitant analgesic requirement, hospital readmissions and length of hospital stay. Analysis will follow the intention-to-treat principle.
