研究目的:

评估Dex在体外循环心脏手术中消除炎症因子的效果以及对心脏手术患者围术期肝脏功能的影响。  

Objectives of Study:

To evaluate the efficacy of Dex in reducing inflammatory markers during cardiac surgery with cardiopulmonary bypass and its impact on perioperative liver function in cardiac surgery patients.

药物成份或治疗方案详述:

Dex组在完成全面监测后,静脉输注右美托咪定负荷剂量(0.5 µg /kg)10分钟,随后以0.4 µg /kg/h速率持续输注直至手术结束。Control组采用相同方式输注等剂量生理盐水。 

Description for medicine or protocol of treatment in detail:

After completing comprehensive monitoring, the Dex group received an intravenous loading dose of dexmedetomidine (0.5 µg/kg) over 10 minutes, followed by a continuous infusion at a rate of 0.4 µg/kg/h until the end of surgery. The Control group received an equal volume of saline administered in the same manner.
