LUMBAR SPINAL STENOSIS
First, we only assessed the effects of systemic lidocaine on postoperative quality of recovery on the early recovery for 48 hours, studies need to focus on longer observation periods for long-term quality of recovery in the future. Second, we did not directly measure the concentrations of lidocaine in patients during the procedure and postoperative follow-up period and performed our study based on doses of lidocaine used in previous studies in the literature. Third, this study did not explore the effect of lidocaine infusion speed and dose on lumbar spinal stenosis surgery, the optimal dosage and speed of lidocaine to accelerate postoperative quality recovery of lumbar spinal stenosis surgery remains to be further studied. Fourth, the study did not distinguish between specific surgical procedures for lumbar spinal stenosis, and only selected open surgery with a posterior approach. Although different surgeries are similar in basic operation, it is true that different surgical methods may have a certain impact on the quality of postoperative recovery. Last but not least, the present study was a single-center clinical trial, whereas the clinical promotion of systemic lidocaine in lumbar spinal stenosis surgery needs a multi-center study.
