Effect of Perioperative Lidocaine on Gastrointestinal Function Recovery After Lumbar Spine Surgery in Adults

Spinal surgery often involves multiple segments. The trauma of surgery is large, the duration of postoperative pain is long, and the pain is severe. Therefore, the use of opioids in perioperative period is large. Although the application of * large amounts of opioids can effectively inhibit pain, it will delay the recovery of urine retention, sedation, respiratory depression and gastrointestinal function. The delayed recovery of gastrointestinal function will increase the postoperative complications, and then increase the length of hospital stay and the cost of patients. Therefore, reducing the dosage of opioids to promote the recovery of gastrointestinal function has become the research direction. Intravenous lidocaine has been proved to be effective in reducing the dosage of opioids during the perioperative period of gastrointestinal surgery and promoting the recovery of postoperative gastrointestinal function. However, there are few studies on the application of lidocaine during the perioperative period of spinal surgery, especially the impact on postoperative gastrointestinal function. In this study, a multicenter, randomized, double-blind, controlled study was conducted to explore the effect of perioperative lidocaine on the recovery of gastrointestinal function after adult lumbar surgery. We hypothesized that lidocaine could shorten the recovery time of gastrointestinal function after lumbar surgery
