■术中机械通气操作可导致健康肺部的呼吸机诱发的肺损伤(VILI)和术后肺部并发症。机械动力(MP)已被开发为降低术后肺部并发症风险的新概念,因为它考虑了引起VILI的所有呼吸力学。最常用的术中模式是容量控制通气(VCV)和压力控制通气(PCV)。在这项研究中,在仰卧位和俯卧位手术的患者的呼吸力学方面,比较了VCV和PCV模式。
■将患者分为4组(80例),仰卧和俯卧的音量控制,压力控制仰卧和俯卧,每位20名患者。MP,呼吸频率,呼气末正压,潮气量,峰值压力,柏拉图压力,驱动压力,吸气时间,高度,年龄,性别,身体质量指数,并通过结构化查询语言查询从“电子数据池”中获得各组患者的预测体重数据。
■VCV组仰卧和俯卧MP值均低于PCV组(P值分别为0.010和0.001)。
■计算的VCV组的仰卧和俯卧MP值显着低于PCV组。对于仰卧位和俯卧位的VILI风险,术中PCV可能被认为是不利的。
UNASSIGNED: Intraoperative mechanical ventilation practices can lead to ventilator-induced lung injury (VILI) and postoperative pulmonary complications in healthy lungs. Mechanical power (MP) has been developed as a new concept in reducing the risk of postoperative pulmonary complications as it considers all respiratory mechanics that cause VILI. The most commonly used intraoperative modes are volume control ventilation (VCV) and pressure control ventilation (PCV). In this study, VCV and PCV modes were compared in terms of respiratory mechanics in patients operated in the supine and prone positions.
UNASSIGNED: The patients were divided into 4 groups (80 patients), volume control supine and prone, pressure control supine and prone with 20 patients each. MP, respiratory rate, positive end-expiratory pressure, tidal volume, peak pressure, plato pressure, driving pressure, inspiratory time, height, age, gender, body mass index, and predictive body weight data of the patients included in the groups have been obtained from \"electronic data pool\" with Structured Query Language queries.
UNASSIGNED: The supine and prone MP values of the VCV group were statistically significantly lower than the PCV group (P values were 0.010 and 0.001, respectively).
UNASSIGNED: Supine and prone MP values of the VCV group were calculated significantly lower than the PCV group. Intraoperative PCV may be considered disadvantageous regarding the risk of VILI in the supine and prone positions.
