Abstract:
Objective To investigate the influence of ultrasound-guided bilateral quadratus lumborum-pudendal nerve block combined with general anesthesia on analgesic effect after laparoscopic radical resection of colorectal cancer.Methods A total of 76 patients with laparoscopic radical resection of colorectal cancer from January 2025 to May 2025 were included.By using the single-double number method,they were divided into block general anesthesia group(double number,n=38)and conventional general anesthesia group(single number,n=38).The block general anesthesia group was treated with ultrasound-guided bilateral quadratus lumborum-pudendal nerve block combined with general anesthesia,while the conventional general anesthesia group was given conventional general anesthesia regimen.The anesthesia recovery indexes,hemodynamic indexes[heart rate(HR),mean arterial pressure(MAP),and saturation of peripheral oxygen(SpO2)]before anesthesia,at the time of skin incision,skin suture,and the end of surgery,as well as the Visual Analogue Scale(VAS)score of pain at rest and activity and Riker Sedation-Agitation Scale score at 3,12,24,and 48 h after surgery,and levels of inflammatory factors and pain stress indexes before surgery and at 24 h after surgery were compared between the two groups.The adverse anesthesia reactions in the two groups were observed.Results The remifentanil dosage,sufentanil dosage,agitation rate,general anesthesia recovery time,first exhaust time,and remedial analgesia utilization rate in the block general anesthesia group were significantly lower or shorter than those in the conventional general anesthesia group(P<0.05).The HR and MAP were lower in the block general anesthesia group than those in the conventional general anesthesia group at the time of skin incision,skin suture,and the end of surgery(P<0.05),and there was no significant difference in SpO2(P>0.05).The VAS scores at rest and activity in the block general anesthesia group at 3,12,and 48 h after surgery were lower than those in the conventional general anesthesia group(P<0.05),and the Riker Sedation-Agitation Scale scores at 24 and 48 h after surgery were lower than those in the conventional general anesthesia group(P<0.05).At 24 h after surgery,the levels of interleukin-6,cortisol,and adrenocorticotropic hormone in the block general anesthesia group were lower than those in the conventional general anesthesia group(P<0.05).The total incidence rates of adverse anesthesia reactions in the block general anesthesia group[7.9%(3/38)]was significantly lower than that in the conventional general anesthesia group[26.3%(10/38),P=0.033].Conclusions The application of ultrasound-guided bilateral quadratus lumborum-pudendal nerve block combined with general anesthesia during laparoscopic radical resection of colorectal cancer has good analgesic and sedative effects.It has small influence on hemodynamics,reduces the dosages of opioids,relieves the inflammatory stress response,and reduces the adverse reactions.
