Aim: To explore the impact of transversus abdominis plane block (TAPB) combined with intravenous injection of lidocaine on the rapid recovery after bariatric surgery. Methods: Eighty patients who underwent elective bariatric surgery from October 2022 to October 2023 were selected as the study subjects, and then divided into a control group (CG) and a study group (SG). The CG received ultrasound-guided TAPB with ropivacaine, while the SG received ultrasound-guided TAPB with ropivacaine plus intravenous lidocaine. The two groups were compared in terms of the total doses of propofol, remifentanil, and sufentanil used, pain intensity, intraoperative conditions, levels of inflammatory factors, additional use of postoperative analgesics, incidence of adverse reactions, and postoperative recovery time. Results: Compared with the CG, the SG showed significant reductions in the total intraoperative doses of propofol, remifentanil, and sufentanil (P<0.05). Additionally, the SG had lower Visual Analogue Scale (VAS) scores at rest and during coughing at 12, 24, and 48 hours postoperatively (P<0.05), as well as lower heart rate (HR) and mean arterial pressure (MAP) values at time points T1–T3 (P<0.05). On the first day after surgery, the levels of tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) in the SG were significantly lower than those in the CG (P<0.05), and the SG also had less additional use of postoperative analgesics (P<0.05). Furthermore, the SG exhibited shorter time to first flatus, first defecation, first ambulation, and shorter length of hospital stay compared with the CG (all P<0.05). Conclusion: TAPB combined with intravenous lidocaine injection may provide effective postoperative analgesia for patients after bariatric surgery and may accelerate their rapid recovery.
