This document provides evidence-based clinical practice guidelines on the use of mechanical ventilation in adult patients with acute respiratory distress syndrome (ARDS).
A multidisciplinary panel conducted systematic reviews and metaanalyses of the relevant research and applied Grading of Recommendations, Assessment, Development, and Evaluation methodology for clinical recommendations.
For all patients with ARDS, the recommendation is strong for mechanical ventilation using lower tidal volumes (4-8 ml/kg predicted body weight) and lower inspiratory pressures (plateau pressure < 30 cm HO) (moderate confidence in effect estimates). For patients with severe ARDS, the recommendation is strong for prone positioning for more than 12 h/d (moderate confidence in effect estimates). For patients with moderate or severe ARDS, the recommendation is strong against routine use of high-frequency oscillatory ventilation (high confidence in effect estimates) and conditional for higher positive end-expiratory pressure (moderate confidence in effect estimates) and recruitment maneuvers (low confidence in effect estimates). Additional evidence is necessary to make a definitive recommendation for or against the use of extracorporeal membrane oxygenation in patients with severe ARDS.
The panel formulated and provided the rationale for recommendations on selected ventilatory interventions for adult patients with ARDS. Clinicians managing patients with ARDS should personalize decisions for their patients, particularly regarding the conditional recommendations in this guideline.
本文件提供了有关急性呼吸窘迫综合征(ARDS)成人患者机械通气使用的基于证据的临床实践指南。
一个多学科小组对相关研究进行了系统评价和荟萃分析,并应用推荐分级的评估、制定与评价(Grading of Recommendations, Assessment, Development, and Evaluation)方法制定临床推荐。
对于所有 ARDS 患者,建议采用较低潮气量(4-8ml/kg 预测体重)和较低吸气压力(平台压<30cmH2O)进行机械通气(对效应估计的信心度为中等)。对于严重 ARDS 患者,建议每天俯卧位超过 12 小时(对效应估计的信心度为中等)。对于中重度 ARDS 患者,建议不常规使用高频振荡通气(对效应估计的信心度很高),但对于较高的呼气末正压(对效应估计的信心度为中等)和募集手法(对效应估计的信心度较低)则有条件推荐。需要更多的证据来明确推荐或反对在严重 ARDS 患者中使用体外膜氧合。
小组制定并提供了有关 ARDS 成人患者选择通气干预的推荐的理由。管理 ARDS 患者的临床医生应根据患者的情况做出个体化决策,特别是针对本指南中的有条件推荐。
