研究目的:

探讨在PCV模式下,以吸气末零流速为目标导向的通气方式对俯卧位下全身麻醉气管插管机械通气患者肺部并发症和全身炎症因子的影响,进而评价以吸气末零流速为目标的PCV模式在全身麻醉俯卧位机械通气下肺保护作用。 方法:纳入全身麻醉气管插管机械通气俯卧位下行脊柱手术的患者并随机分组,测量不同时刻患者的气道峰压、气道平台压、肺动态顺应性、氧合指数、术毕肺不张发生率、术后72h内肺部并发症发生率等数据评价PCV+吸气末零流速模式对肺脏的保护作用;并测量不同时刻巨噬细胞炎性蛋白2的水平探究PCV+吸气末零流速模式对全身炎症反应的影响。 预期结果:以吸气末零流速为目标的PCV模式在全身麻醉俯卧位机械通气下的具有肺保护作用。  

Objectives of Study:

To investigate the effect of zero flow rate at the end of inspiration oriented ventilation mode on pulmonary complications and systemic inflammatory factors in patients undergoing tracheal intubation mechanical ventilation under general anesthesia in prone position under PCV mode, and then to evaluate the lung protection effect of PCV mode targeting zero flow rate at the end of inspiration in prone position under general anesthesia. Methods: Patients undergoing spinal surgery in prone position with tracheal intubation and mechanical ventilation under general anesthesia were randomly divided into groups. The peak airway pressure, airway platform pressure, pulmonary dynamic compliance, oxygenation index, the incidence of postoperative atelectasis, and the incidence of pulmonary complications within 72 hours after surgery were measured at different times to evaluate the protective effect of PCV+zero end inspiratory flow mode on the lungs; The level of macrophage inflammatory protein 2 at different times was measured to explore the influence of zero flow rate mode at the end of inspiration of PCV+on systemic inflammatory response. Expected results: PCV model with zero inspiratory end flow rate as the target has lung protection effect under general anesthesia prone position mechanical ventilation.
