研究目的:

1.验证术中驱动压指导PEEP滴定对减小通气机械功率的可行性; 2.分析不同机械功率对于术后PCCs以及术中肺功能的影响; 3.绘制ROC曲线,通过AUC值来了解机械功率参数的最适宜预测腹腔镜结直肠手术老年人发生PCCs的值,对于发生PCCs的高危人群进行预防性治疗,为临床干预提供理论依据。  

Objectives of Study:

1. To verify the feasibility of intraoperative driven pressure-guided PEEP titration to reduce the mechanical power of ventilation; 2. To analyze the effects of different mechanical powers on postoperative PCCs and intraoperative lung function; 3. Draw the ROC curve to understand the most suitable value of mechanical power parameters to predict the occurrence of PCCs in the elderly undergoing laparoscopic colorectal surgery through the AUC value, and carry out preventive treatment for the high-risk groups of PCCs, so as to provide a theoretical basis for clinical intervention.
