Observation on the Analgesic Effect of Bilateral Erector Ridge Muscle Plane Block after Lumbar Posterior Approach Surgery
Objective:To analyze the analgesic effect of bilateral erector ridge muscle plane block after lumbar posterior approach surgery.Method:A total of 60 patients who were admitted to Pingxiang Hospital of Traditional Chinese Medicine from July 2021 to July 2023 and were diagnosed as lumbar degenerative diseases or lumbar fracture and required surgical treatment were selected as the study subjects.They were divided into observation group and control group by random number table method,with 30 cases in each group.The control group was given combined intravenous and inhalation general anesthesia,and the observation group was given ultrasound-guided bilateral erector ridge muscle plane block+combined intravenous and inhalation general anesthesia,both groups were equipped with intravenous self controlled analgesia pumps after surgery.Intraoperative and postoperative opioid and intraoperative muscle relaxants were compared between the two groups,and pain scores in 6,12,24 and 48 h postoperative follow-up were compared between the two groups according to visual analogue scale(VAS),the number of therapeutic analgesia administration of patient-controlled analgesic pump and adverse reactions were recorded.Result:The amount of Sufentanil used during and after surgery,Remifentanil and Atracurium used during surgery in the observation group were less than those in the control group(P<0.05).The postoperative VAS scores of the observation group were lower than those of the control group at all time periods(P<0.05).The number of postoperative remedial analgesic doses was less than that of the control group,the difference was statistically significant(P<0.05).The incidence of adverse reactions in the observation group was lower than that in the control group,the difference was statistically significant(P<0.05).Conclusion:Ultrasonic-guided bilateral erector ridge muscle plane block has better analgesic effect in patients undergoing lumbar posterior approach surgery,which not only reduces the use of opioids and muscle relaxers,but also reduces postoperative pain.The number of postoperative intravenous analgesia administration and adverse reactions of patients are reduced,and the clinical application is safe and reliable.
