NCT07552766
This study is a prospective, randomized, double-blind clinical trial evaluating whether intraoperative intravenous lidocaine infusion (IVLI) reduces opioid requirements and improves postoperative pain control in children undergoing surgical fixation of upper extremity long bone fractures under general anesthesia. Ninety pediatric patients, ages 3-18 will be enrolled and randomized 1:1 to receive either IV lidocaine or placebo (normal saline) during surgery. All participants will receive standardized anesthesia care and postoperative pain management. Opioid consumption and pain scores will be measured intraoperatively and throughout the postoperative recovery, with the primary outcome focused on total opioid use 60 minutes after arrival to the post-anesthesia care unit (PACU). Secondary outcomes include opioid use at additional time points, postoperative pain scores, PACU length of stay, rescue antiemetic use and the relationship between infusion duration and outcomes. Patients will be closely monitored for signs of local anesthetic systemic toxicity and other adverse events. The goal of this study is to determine whether IV lidocaine is an effective opioid-sparing adjunct in pediatric orthopedic surgery and to support safer, multimodal analgesia strategies.
NCT07543809
This is a randomized controlled clinical trial to explore the efficacy and mechanism of Tiaozhong-Yiqi Decoction (TZYD) in treating substance withdrawal syndrome, combining network pharmacology analysis and clinical validation. A total of 80 patients meeting the diagnostic criteria for withdrawal syndrome were enrolled and randomly divided into two groups: the TZYD intervention group (n=40) received Tiaozhong-Yiqi Decoction 200mL twice daily for 3 consecutive months, combined with routine care; the control group (n=40) received only routine care (diet guidance, psychological counseling, sleep management). The primary outcome was the improvement of withdrawal syndrome symptoms, evaluated by a standardized clinical scale before and after treatment. Secondary outcomes included changes in serum neurotransmitters (dopamine, norepinephrine, 5-hydroxytryptamine), inflammatory factors (IL-6, IL-1β, TNF-α), brain-derived neurotrophic factor (BDNF), and quality of life scores (QOL-DA V2.0). This study aims to provide clinical evidence and a theoretical basis for the application of Tiaozhong-Yiqi Decoction in the treatment of withdrawal syndrome, and to explore its potential regulatory mechanism on the neuroendocrine and immune systems.
