Condition: Laparoscopic Surgery · Liposomal Bupivacaine · Transversus Abdominis Plane Block · Sponsor: Beijing Tiantan Hospital
Laparoscopic surgery has become the preferred approach for abdominal surgical interventions due to its advantages of minimal invasiveness, rapid recovery, and reduced complication rates. Despite its minimally invasive nature, postoperative pain persists and adversely affects patient recovery. In the absence of effective pain management, acute pain may progress to chronic pain. Although opioids provide reliable analgesic effects, their associated adverse reactions limit their application following minimally invasive procedures. Regional analgesia serves as the cornerstone of multimodal analgesia, and ultrasound-guided nerve block techniques have become increasingly refined. Ultrasound-guided transversus abdominis plane block(TAPB) generally fulfills intraoperative and postoperative analgesic requirements for laparoscopic surgeries by inhibiting the transmission of nociceptive stimuli in the targeted region, thereby aiding in the prevention of central sensitization. Conventional TAPB utilize local anesthetics, which demonstrate excellent efficacy in alleviating incisional pain. However, the short duration of analgesia provided by conventional local anesthetics significantly compromises their clinical utility.Liposomal bupivacaine(LB) is a novel, long-acting, sustained-release amide-type local anesthetic, providing localized analgesic effects for up to 72 hours.However, its efficacy and safety in laparoscopic surgery not yet been fully validated. Based on this premise, the prese…
