研究目的:

本课题拟通过前瞻性研究观察右美托咪定及右美托咪定复合地塞米松对下肢骨折手术患者围术期瘙痒的影响,探讨右美托咪定与地塞米松对芬太尼腰麻后瘙痒的临床作用,为芬太尼腰麻过程中并发症的预防提供参考。  

Objectives of Study:

This prospective study aims to observe the effects of dexmedetomidine alone and dexmedetomidine combined with dexamethasone on perioperative pruritus in patients undergoing lower limb fracture surgery. It further explores the clinical roles of dexmedetomidine and dexamethasone in managing pruritus induced by fentanyl spinal anesthesia, aiming to provide references for the prevention of complications during fentanyl spinal anesthesia.
