研究目的: |
系统对比VC、VC-AF、PC 三种通气模式对 Trendelenburg 体位妇科腹腔镜手术患者呼吸力学及氧合功能的影响,明确三种通气模式对患者术术后7天内肺部并发症(肺部感染、肺不张、胸腔积液、ARDS等)发生率的差异,明确最优的肺保护通气模式 。 |
||||||||||||||||||||||
|
Objectives of Study: |
Systematically compare the effects of three ventilation modes (VC, VC-AF and PC) on respiratory mechanics and oxygenation in patients undergoing gynecological laparoscopic surgery in the Trendelenburg position; to clarify the differences in the incidence of postoperative pulmonary complications (including pulmonary infection, atelectasis, pleural effusion, ARDS, etc.) within 7 days after surgery among the three modes, and to identify the optimal lung-protective ventilation strategy. |
