RESUMEN
Objective To analyze the clinical effect of ultrasound-guided quadratus lumborum block(QLB)and erector spinae plane block(ESPB)in elderly patients with laparoscopic colorectal cancer surgery.Methods A total of 75 elderly patients who underwent elective laparoscopic radical resection of colorectal cancer in wenzhou central hospital,from August 2021 to March 2022 were selected and divided into quadratus lumborum group(group Q,n=25),erector spinae muscle group(group E,n=25)and group C(n=25).Group Q received QLB combined with general anesthesia,group E received ESPB combined with general anesthesia,the group C was given tracheal intubation with total intravenous general anesthesia.The perioperative anesthesia and analgesic dosage,postoperative recovery quality,resting and cough visual analogue scale(VAS)scores were compared among the groups.Results In contrast to the group C,the number of effective PCIA compressions,the dose of sufentanil,and the analgesic rescue rate were significantly decreased in groups Q and E(P<0.05);In contrast to the the group C,the spontaneous breathing,eye opening and tracheal extubation time of patients in group Q and group E were apparently shortened(P<0.05),and patients in group Q and group E recovered indoor nausea and vomiting,lethargy,restlessness and respiratory depression The number of cases was apparently reduced(P<0.05);at each time point from 2 to 48 hours after operation,compared with the group C,the VAS scores at rest and cough in groups Q and E were apparently decreased(P<0.05).However,there was no significant difference in the above indicators between the group Q and the group E(all P>0.05).Conclusion Ultrasound-guided QLB and ESPB for laparoscopic colorectal cancer surgery can both improve the quality of recovery and achieve satisfactory analgesia in elderly patients.
