The CONSORT 2010 flowchart is shown in Fig. CONSORT 2010 Flow Diagram.Demographic characteristics.As shown in Fig. The global QOR-15 scores in patients before or who suffered lumbar spinal stenosis surgery with or without Lidocaine. The scores are presented as median, IQR, and min to max. ***As shown in Fig. The secondary outcomes of first flatus, catheter removal time, and underground time in patients who suffered lumbar spinal stenosis surgery with or without Lidocaine. The hours are presented as median, IQR, and min to max. ***Systemic lidocaine could reduce acute NRS pain scores at 12th hours after lumbar spinal stenosis surgery (SD 3.5 (3–4) vs. 3 (3–4), The NRS scores in patients who suffered lumbar spinal stenosis surgery with or without Lidocaine. The scores are presented as mean and standard deviation. *The placebo group had higher cumulative consumption of opioids (sufentanil) 48 hours after surgery compared with the lidocaine group (median 28 μg, IQR 22.5–32, compared with median 26 μg, IQR 16–28; The sufentanil rescues consumption (As shown in Fig. The cytokines in patients before or post-lumbar spinal stenosis surgery with or without Lidocaine. The cytokines are presented as median, IQR, and min to max. Pre-, before the lumbar spinal stenosis surgery. Post-, 48 hours later when patients suffered the lumbar spinal stenosis surgery. *The incidence of PONV 24 hours and 48 hours after surgery was 8 (28.6%) in the placebo group versus 5 (17.9%) in the lidocaine group, and 7 (25%) in the placebo group versus 5 (17.9%) in the lidocaine group, and the difference was not statistically significant (Complications for patients treated with placebo or lidocaine.PONV, postoperative nausea or vomiting.
