Comparison between midazolam and propofol in acute phase for ventilated patients with sepsis: a post-hoc analysis of the DESIRE trial.

Abstract

AimThere are few assessments of sedatives during the acute phase under sedation protocols for patients with sepsis. We aimed to compare the influence of different sedation strategies using midazolam and propofol under light sedation on clinical outcomes of ventilated patients with sepsis.MethodsThis study was a post‐hoc analysis of data from the dexmedetomidine for sepsis in the ICU Randomized Evaluation (DESIRE) trial. Patients were divided into propofol and midazolam groups based on continuously used drug, and sedation control between groups compared on day three. We assessed the incidence of delirium, length of ICU stay, number of ventilator‐free days within the first 28 days, and mortality after 28 days.ResultsThe midazolam and propofol groups consisted of 51 and 66 patients, respectively. Both groups had similar characteristics, except for age and emergency surgery. The number of well‐controlled sedation patients in the propofol group on day three was significantly higher than that in the midazolam group (odds ratio [OR] 3.9, 95% CI [1.30, 11.7]). The incidence of daily coma and delirium within the initial week was different between groups and increased with midazolam administration (P = 0.0138). The number of Confusion Assessment Method for ICU‐positive patients was significantly higher in the midazolam group than in the propofol group (OR 5.71, 95% CI [2.30, 14.2]).ConclusionIn patients with sepsis required mechanical ventilation, sedation with midazolam based on a light sedation protocol may be associated with inappropriate sedation during the acute phase, with increased coma and delirium as compared to propofol.
