Study Overview
Brief Summary
Compared with traditional laparotomy, laparoscopic surgery offers advantages including minimal invasiveness, accelerated patient recovery, and reduced hospital stay. Although postoperative incision pain is generally less severe than that following laparotomy, it remains a notable clinical issue that impedes patient recovery. The majority of patients report incisional discomfort, with approximately 30% to 50% requiring oral analgesics to alleviate pain symptoms. Within the first two days after laparoscopic procedures, most patients experience varying degrees of incisional pain, with peak intensity typically occurring within hours after surgery and gradually subsiding over two to three days. Studies indicate that local infiltration anesthesia at the surgical site significantly ameliorates postoperative incision pain, enhances analgesic efficacy, and shortens recovery time in patients undergoing laparoscopic surgery.Liposomal bupivacaine(LB) is a novel, long-acting, sustained-release amide-type local anesthetic, providing localized analgesic effects for up to 72 hours. Some researchers have reported the analgesic effects of LB VS traditional local anesthetics infiltration, but the current research results are highly heterogeneous. More prospective studies are needed to evaluate whether LB infiltration is superior to the traditional local anesthetics for the management of postoperative pain. The investigators designed this study to compare the analgesic effect of using LB plus bupivacaine for local infiltration with bupivacaine along for patients after laparoscopic surgery.
