Abstract:
Objective:To evaluate the improved efficacy of transversus abdominal plane (TAP)-rectus sheath (RS) block combined with general anesthesia in the patients undergoing laparoscopic pancreaticoduodenectomy.Methods:Fifty-six American Society of Anesthesiologists physical status Ⅰ-Ⅲ patients of both sexes, aged 45-64 yr, with body mass index of 18-25 kg/m 2, scheduled for elective laparoscopic pancreaticoduodenectomy, were divided into 2 groups ( n=28 each) using a random number table method: general anesthesia group (group G) and TAP-RS block plus general anesthesia group (group TRG). In group TRG, after induction of general anesthesia, bilateral TAP-RS block was performed with 0.375% ropivacaine mixed with 0.5 μg/kg dexmedetomidine under ultrasound guidance, 20 ml was injected into the plane of bilateral transverse abdominis, and 10 ml was injected into the posterior sheath of the bilateral rectus abdominis, and the tube was placed on the plane of the transverse abdominis, and 5 ml/h was continuously pumped after operation.In both groups, anesthesia was induced with IV midazolam, sufentanil, etomiddate and cisatracurium besylate and maintained using combined intravenous-inhalational anesthesia, and patient-controlled intravenous analgesia (PCIA) was performed after operation.Pulmonary function indexes were measured before induction of anesthesia (T 0) and at 6, 12 and 24 h after removal of the tracheal tube (T 1-3). Blood gas analysis was performed at T 0, T 2 and T 3.The occurrence of high/low blood pressure, tachycardia/bradycardia, consumption of opioids, PACU stay time, pressing times of PCIA within 24 h after surgery, rescue analgesia, time of passing the first flatus, the first postoperative off-bed time, length of postoperative hospital stay, and 48 h quality of recovery-40 (QoR-40) were recorded.The occurrence of adverse reactions and nerve block-related complications were recorded within 48 h after operation. Results:Conversion to laparotomy during operation was found in 4 patients, changing the scope of resection in 2 patients, and a total of 50 patients were enrolled in this study.Compared with group G, the pressing times of PCIA was significantly reduced, the requirement for postoperative rescue analgesia was decreased, the intraoperative consumption of sufentanil and remifentanil was reduced, the incidence of intraoperative hypertension and tachycardia was decreased, the FEV1, FVC and PEFR were increased at T 2, 3, the 48 h QoR-40 score was increased, the time of passing the first flatus, the first postoperative off-bed time, and length of postoperative hospital stay were shortened, the incidence of nausea, agitation, somnolence, and hypoxemia was decreased ( P<0.05), and no significant change was found in the indicators of blood gas analysis at each time point in group TRG ( P>0.05). Nerve block-related complications were not found in group TRG. Conclusion:Compared with general anesthesia alone, TAP-RS block combined with general anesthesia is helpful in carrying out anesthetic model of low-consumption opioids and improving the quality of early postoperative recovery when used in the patients undergoing laparoscopic pancreaticoduodenectomy.
