适应性辅助通风 (ASV) 与重症患者的同步间歇性强制通风 (SIMV) 相比,显著降低了机械通风的持续时间和气道峰值压力. ASV可能有助于肺部保护性通风和断奶,尽管需要进一步的研究.
科学领域:
- 关键护理医学 关键护理医学
- 肺部病理学 肺部病理学
- 呼吸系统疗法 呼吸系统疗法
背景情况:
- 机械通风对于重症患者至关重要.
- 选择通风模式会影响患者的治疗结果.
- 适应式支通风 (ASV) 和同步间歇式强制通风 (SIMV) 是常见的模式,有效性受到争议.
研究的目的:
- 在重症患者中系统地审查和元分析ASV与SIMV的比较疗效.
- 评估ASV对机械通风持续时间,通风器日和重症监护室 (ICU) 停留时间 (LOS) 的影响.
- 评估二次结果,包括生理参数,如气道压力峰值 (P-峰值),血液动力学和气体交换.
主要方法:
- 在PubMed,Web of Science和Scopus进行了系统的文献搜索.
- 包括的研究集中在接受ASV或SIMV的重症患者身上.
- 主要结局是机械通风持续时间,通风器日和ICU LOS;次要结局包括生理参数.
主要成果:
- 与SIMV相比,ASV显著减少了机械通风持续时间 (MD: -0.80天) 和呼吸机日 (MD: -1.42天).
- 与SIMV相比,ASV与P峰值 (MD: -2.16) 显著较低相关.
- 在ICU LOS,心率,分钟体积,平均动脉压,PCO2,PO2或呼吸率方面没有发现显著差异.
结论:
- ASV在减少机械通风持续时间和气道峰值压力方面比SIMV具有优势.
- 在ICU环境中,ASV可能有利于促进肺部保护性通风和断奶.
- 高异质性和研究质量的差异限制了目前的发现,需要进一步研究.
