Health condition(s) or Problem(s) studiedcardiovascular diseases
Date of first enrollment21/07/2022
Target sample size60
Countries of recruitment
Study typeInterventional
Intervention(s)Isoflurane group: Isoflurane infusion starts 3 ml/hr to Anesthetic Conserving Device. Isoflurane infusion is adjusted between 0 to 7 ml/hr, end tidal isoflurane concentration 0 to 1 % to achieve target sedation level. Dexmedetomidine group: Dexmedetomidine is adjusted between 0.2 to 0.7 mcg/kg/hr to achieve target sedation level.


Primary OutcomeGeometric mean of the percentage of eccessive mean tidal volume (over 8 ml/kg PBW) every 5 minutes during the first 2 hours after sedation.
Secondary OutcomeNumber of ventilator setting adjustments, asynchrony rate, time not achieving target sedation level, duration of ventilation, cumulative opioid dose, cumulative cathecholamine dose, troponin I change rate, presence of delirium, acute kidney injury, P/F ratio change rate, liver injury, nausea/vomiting, ICU stay, 28-day mortality
