ObjectiveTo evaluate the impact of local lidocaine incision-site injection in patients undergoing cesarean deliveries (CD), on post operative pain and analgesic requirements.Study DesignIn this prospective, double-blinded, placebo-controlled study, patients undergoing elective CD were randomly assigned to receive 1% lidocaine solution or placebo to the incision site, prior to the performance of a Pfannenstiel incision. Pain intensity was evaluated for up to 48 hours after surgery and analgesic requirements of the patients were recorded.ResultsDuring the study period, 153 patients were enrolled; 77 received pre-emptive analgesia with lidocaine and 76 received a placebo. No significant differences were noted between the groups in respect to parity, previous CD, maternal age and gestational age. Pain scores or requirements of analgesia did not differ between the groups.ConclusionPre-emptive analgesia with local incision-site injection with lidocaine does not seem beneficial in reducing post cesarean pain scores and analgesic requirements.
