MV duration mechanical ventilation duration, time (min) between ICU admission and extubation; VFDS, ventilator-free days, 1 point [for] each day during the measurement period that [patients] are both alive and free of mechanical ventilation in the first 28 days; ICU discharge, time (days) between ICU admission and discharge; hospital discharge, time (days) between ICU discharge and hospital discharge. Note: Results are presented as median (range 25–75) and percentages, *p < 0.01 vs morphine group
