摘要

Purpose

To evaluate the analgesic efficacy of ultrasound-guided quadratus lumborum block (QLB) for laparoscopic renal surgery.

Methods

Sixty-eight patients who underwent unilateral laparoscopic renal surgery were enrolled. All patients were separated into two groups: group QLB (n = 34) and group C (n = 34). Patients in the QLB group underwent unilateral anterior QLB before the induction of anesthesia. Patients in group C underwent laparoscopic renal surgery with no block. Postoperative NRS scores at rest and during movement at 6, 12, 24, 48 h were assessed. Remedial analgesia and the incidence of adverse reactions within 48 h after surgery were recorded. The quality of recovery was compared at 24 and 48 h after the operation via the postoperative quality recovery scale.

Results

At 6, 12, 24 h postoperatively, the QLB group had lower resting and moving NRS scores than did the C group (P < 0.05). The QLB group had lower numbers of PCAs, remedial analgesia and incidences of nausea and vomiting within 48 h (P < 0.05). The time to first walk and exhaust was shorter in the QLB group (P < 0.05). The recovery rates of nociceptive and emotional factors at 24, 48 h in the QLB group were greater (P < 0.05). The recovery rates of the activities of daily living (ADL) factors at 24 h in the QLB group were greater (P < 0.05).

Conclusions

QLBs are more effective at alleviating pain in patients undergoing laparoscopic renal surgery, which is beneficial for reducing the use of opioids, alleviating adverse reactions, improving the quality of recovery.
