Sedation modality in acute respiratory distress syndrome: does method of sedation affect length of stay, outcomes, or adverse events? A systematic review

Introduction

Acute respiratory distress syndrome (ARDS) is a life-threatening, diffuse inflammatory pulmonary condition characterised by the Berlin criteria. Incidence of ARDS is estimated at 2.5–19% globally with high mortality and morbidity. Interest has been increasing in the use of inhaled sedatives because of a more rapid awakening and fewer adverse effects compared with intravenous propofol. The primary aim of this systematic review protocol is to investigate the length of critical care stay between ARDS patients who have been mechanically ventilated with inhaled anaesthetic sedatives (ie, sevoflurane and isoflurane) compared with those patients who are prescribed conventional sedatives (ie, propofol).
