标题：Combined use of transversus abdominis plane block and laryngeal mask airway during implementing ERAS programs for patients with primary liver cancer: a randomized controlled trial
摘要：The incidence and mortality of primary liver cancer are very high and resection of tumor is the most crucial treatment for it. We aimed to assess the efficacy and safety of combined use of transversus abdominis plane (TAP) block and laryngeal mask airway (LMA) during implementing Enhanced Recovery After Surgery (ERAS) programs for patients with primary liver cancer. This was a prospective, evaluator-blinded, randomized, controlled parallel-arm trial. A total of 96 patients were enrolled (48 in each group). Patients in the control group received general anesthesia with endotracheal intubation, while patients in the TAP + LMA group received general anesthesia with LMA and an ultrasound-guided subcostal TAP block. The primary end-point was postoperative time of readiness for discharge. The secondary end-points were postoperative pain intensity, time to first flatus, quality of recovery (QoR), complications and overall medical cost. Postoperative time of readiness for discharge in the TAP + LMA group [7 (5–11) days] was shorter than that of the control group [8 (5–13) days, P = 0.004]. The postoperative apioid requirement and time to first flatus was lower in the TAP + LMA group [(102.8 ± 12.4) µg, (32.7 ± 5.8) h, respectively] than the control group [(135.7 ± 20.1) µg, P = 0.000; (47.2 ± 7.6) h, P = 0.000; respectively]. The QoR scores were significantly higher in the TAP + LMA group than the control group. The total cost for treatment in the TAP + LMA group [(66,608.4 ± 6,268.4) CNY] was lower than that of the control group [(84,434.0 ± 9,436.2) CNY, P = 0.000]. There was no difference in complications between these two groups. The combined usage of a TAP block and LMA is a simple, safe anesthesia method during implementing ERAS programs for patients with primary liver cancer. It can alleviate surgical stress, accelerate recovery and reduce medical cost.
