Intravenous infusion of lignocaine has emerged in recent years as a feasible, cost-effective, and safe method to provide postoperative analgesia. There is, however, no literature about this perioperative pain control modality in Chinese patients. This study aimed to determine whether perioperative intravenous lignocaine safely reduces postoperative pain, shortens postoperative ileus, and reduces the length of hospital stay in laparoscopic colorectal surgery.
