Objectives of Study:

Comparative Effects of Dexmedetomidine Infusion Timing on Postoperative Delirium in Elderly Patients with Lower Limb Fractures: Identifying the Optimal Timing for Delirium Prevention

药物成份或治疗方案详述:

试验组均采用单次静脉输注右美托咪定(剂量 0.5μg/kg),对照组给予等量生理盐水。操作过程中必须始终维持严格的无菌技术。 术前给药组:椎管内麻醉穿刺前15分钟开始输注,输注时间≥10 分钟; 术中给药组:切皮前15分钟开始输注,输注时间≥10 分钟; 对照组:同期输注等量 0.9% 氯化钠注射液,输注速率及时间与实验组一致。 

Description for medicine or protocol of treatment in detail:

All experimental groups received a single intravenous infusion of dexmedetomidine (at a dose of 0.5 μg/kg), while the control group received an equivalent volume of normal saline. Strict aseptic technique must be maintained throughout the procedure. Preoperative group: Infusion started 15 minutes before neuraxial anesthesia puncture, with an infusion duration of ≥10 minutes. Intraoperative group: Infusion started 15 minutes before skin incision, with an infusion duration of ≥10 minutes. Control group: An equivalent volume of 0.9% sodium chloride injection was infused concurrently, with the infusion rate and duration consistent with the experimental groups.
