Observational Study
Intraoperative initiation of a modified ARDSNet protocol increases survival of septic patients with severe acute respiratory distress syndrome.
Heart & Lung : the Journal of Critical Care 2018 November
PURPOSE: To assess the intraoperative initiation and feasibility of a modified NIH-NHLBI ARDS Network Mechanical Ventilation Protocol (mARDSNet protocol) in septic patients with severe ARDS.
MATERIALS AND METHODS: This prospective observational study included consecutive adult septic patients with severe ARDS who underwent emergency abdominal surgery prior to intensive care unit (ICU) admission. The primary outcome was survival to hospital discharge and at 90 days. Secondary outcomes were intraoperative adverse events and ICU length of stay.
RESULTS: Seven patients were included. A statistically significant difference in lung compliance [ε=0.150, F(1.053, 3.158)=31.098, p=0.010] and driving pressure [ε=0.263, F(1.844, 5.532)=7.042, p=0.031] was observed with time, while plateau pressure did not changed significantly during surgery [ε=0.322, F(2.256, 6.769)=1.920, p=0.219]. Also, PEEP values were constantly increased during surgery [ε=0.252, F(1.766, 5.297)=9.994, p=0.017], with the highest values being observed towards to the end of the procedure. No intraoperative adverse events were observed. Mean (±SD) ICU length of stay was 10.43 (±2.64) days, while all patients survived to hospital discharge and at 90 days.
CONCLUSIONS: The intraoperative implementation of our mARDSNet protocol is feasible and may increase the survival of septic patients with severe ARDS if initiated prior to ICU admission.
