Abstract:
Objective:To investigate the efficacy and safety of ultrasound-guided of lumbar square muscle block on the arcuate ligament in laparoscopic surgery for gastrointestinal tumors.Methods:A retrospective study was conducted on 106 patients who underwent laparoscopic gastrointestinal tumor surgery in Rugao Branch of Affiliated Hospital of Nantong University from January 2020 to December 2022, 53 patients(observation group) were given the ultrasound-guided of lumbar square muscle block on the arcuate ligament before general anesthesia, 53 patients(control group) were given only general anesthesia. The sensory block planes were recorded at 5 min and 15 min after the block in the observation group, and the hemodynamic indexes, stress indexes at differences time points and postoperative analgesia were compared between the two groups.Results:Most patients in the observation group could monitor the T 8 - L 1 sensory block plane at 5 min after block, and the T 5 - L 2 sensory block plane could be reached at 15 min after block, and the percentage of block was 100.00%(53/53). The results of repeated measurement variance analysis (ANOVA) showed that the intergroup - time point interaction of heart rate (HR) and mean arterial pressure (MAP) between the two groups had statistical differences ( P<0.05); the intergroup-time point interaction of the levels of noradrenaline (NE), epinephrine (E), adrenocorticotropic hormone (ACTH), cortisol (Cor) between the two groups had statistical differences ( P<0.05); the intergroup - time point interaction of the resting and active visual analog scale (VAS) scores between the two groups had statistical differences ( P<0.05). The amount of propofol, remifentanil, the number of effective patient-controlled intravenous analgesia (PCIA) compressions, and the total number of PCIA compressions in the observation group were lower than those in the control group: (1 128.36 ± 137.95) mg vs. (1 415.18 ± 153.24) mg, (1.47 ± 0.49) mg vs. (2.76 ± 0.74) mg, (4.25 ± 0.87) times vs. (8.63 ± 0.94) times, (10.27 ± 1.25) times vs. (15.75 ± 1.47) times, there were statistical differences ( P<0.05). The rate of remedial analgesia within 48 h after surgery between the two groups had no statistical difference ( P>0.05). The awakening time, first time out of bed, first time exhaust and hospitalization time in the observation group were shorter than those in the control group: (4.75 ± 0.57) min vs. (7.02 ± 0.64) min, (11.65 ± 1.47) h vs. (15.87 ± 1.94) h, (14.79 ± 2.12) h vs. (19.59 ± 3.30) h, (4.78 ± 0.72) d vs. (7.14 ± 0.98) d, there were statistical differences ( P<0.05). The incidence of adverse reactions between the two groups had no statistical difference ( P>0.05). Conclusions:Ultrasound-guided of lumbar square muscle block on the arcuate ligament in laparoscopic surgery for gastrointestinal tumors has significant analgesic effects, can reduce intraoperative anesthetic maintenance dose, maintain intraoperative hemodynamic stability, reduce postoperative pain sensation and stress response, reduce postoperative analgesic injection dose, shorten postoperative wakefulness time, and accelerate recovery.
