研究目的:

本研究旨在通过随机对照实验,评估 10°反向Trendelenburg体位联合去甲肾上腺素在耳科手术中术野优化效果,研究成果将为耳科手术出血控制提供更安全的循证方案。主要目的:术野清晰度改善(根据 Modena 出血评分评估手术区域的清晰度),为临床应用优化麻醉方案提供参考。次要目的:术中出血量(通过纱布称重)、手术时间、血流动力学稳定性、术后并发症的发生率,提供临床措施和理论证据。  

Objectives of Study:

This randomized controlled trial aims to evaluate how the 10° reverse Trendelenburg position combined with norepinephrine improves the surgical field during ear surgery.The research results provide a safer, evidence-based solution for bleeding control in ear surgery.The main objective is to improve the clarity of the surgical field, evaluated using the Modena bleeding score, and to provide a reference for optimizing anesthetic management in clinical practice. The secondary objective is to provide clinical measures and theoretical evidence regarding intraoperative blood loss (measured by gauze), operation time, hemodynamic stability, and the incidence of postoperative complications.
