Abstract:: BACKGROUND: Volatile anesthetics are used more commonly for sedation in the intensive-care-unit (ICU). However, evidence for long-term use remains low. We therefore conducted a randomized-controlled trial comparing sevoflurane with intravenous sedation with particular focus on efficacy and safety. METHODS: In this prospective, randomized-controlled phase-IIb monocentric clinical-trial ICU patients requiring at least 48 h of sedation were randomized to receive sevoflurane (S) or propofol/midazolam (P). Sedation quality was monitored using the Richmond-Agitation-Sedation-Scale. Following termination of sedation, the time to spontaneous breathing and extubation, opioid consumption, hemodynamics, ICU and hospital length of stay (LOS) and adverse events were recorded. RESULTS: 79 patients were eligible to randomization. Sedation quality was comparable between sevoflurane (n = 39) and propofol (n = 40). However, the use of sevoflurane lead to a reduction in time to spontaneous breathing (26 min vs. 375 min, P < 0.001). Patients sedated with propofol had lower opioid requirements (remifentanil:400 μg/h vs. 500 μg/h, P = 0.007; sufentanil:40 μg/h vs. 30 μg/h, P = 0.007) while hemodynamics, LOS or the occurrence of adverse events did not differ. CONCLUSION: ICU patients sedated with sevoflurane >48 h may return to spontaneous breathing faster, while the quality of sedation is comparable to a propofol-based sedation regime. Sevoflurane might be considered to be safe for long-term sedation in this patient population, while being non-inferior compared to propofol.
