Evaluation of the Initiation Effect of QLB Combined with General Anesthesia in the “Painless Mode” during Gynecological Laparoscopic Surgery

Abstract

Objective: To evaluate the painless mechanism of the quadratus lumborum block at the level of the arcuate ligament (denoted as QLB) combined with general anesthesia during gynecological laparoscopic surgery. Methods: Forty patients undergoing gynecological laparoscopic surgery were selected and evenly divided by ball-drawing. The combined group received QLB combined with general anesthesia, while the reference group received only general anesthesia. The initiation effects of the painless mode were compared between the two groups. Results: The analgesic indicators in the combined group were significantly superior. Except for before 10 minutes of anesthesia (i.e., T0), the hemodynamics in the combined group were more favorable. At different postoperative time points, the pain scores of the combined group were lower in both resting and active states, with P < 0.05 between the groups. Conclusion: QLB combined with general anesthesia can significantly improve the analgesic effect, stabilize hemodynamics, alleviate postoperative pain, and enhance anesthesia safety in patients undergoing gynecological laparoscopic surgery.
