Sumario:OBJECTIVES: To describe sedative and analgesic drug utilization in a cohort of critically ill patients with coronavirus disease 2019 and compare standard sedation with an alternative approach using inhaled isoflurane. DESIGN: This was a retrospective cohort study designed to compare doses of sedatives between ICU patients receiving standard IV sedation and patients receiving mixed sedation including inhaled isoflurane. Data were obtained from electronic medical records. SETTING: ICU at large academic medical center where mechanical ventilation was delivered with Draeger Apollo (Draeger Medical, Telford, PA) anesthesia machines. PATIENTS: Consecutive adult patients (≥ 18 yr) with confirmed coronavirus disease 2019 admitted to ICU between April 2, 2020, and May 4, 2020. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Thirty-five mechanically ventilated patients were included in the study, with a mean (sd) age of 59.4 (12.8) years. Twenty-three patients (65.7%) were men. Seventeen patients (48.6%) received standard IV sedation, whereas 18 (51.4%) also received isoflurane. The mean duration of mechanical ventilation (sd) was 23.3 (11.6) days in the standard sedation group and 23.8 (12.5) days in the isoflurane group. Mean (sd) duration of isoflurane exposure was 5.61 (2.99) days, representing 29.1% of total sedation time (sd, 20.4). Cumulative opioid exposure did not differ between the standard sedation and isoflurane sedation groups (mean morphine milligram equivalent 6668 [sd, 1,346] vs 6678 [sd, 2,000] mg). However, the initiation of isoflurane in patients was associated with decreased utilization of propofol (mean daily amount 3,656 [sd, 1,635] before vs 950 [sd, 1,804] mg during isoflurane) and hydromorphone (mean daily amount 48 [sd, 30] before vs 23 [sd, 27] mg). CONCLUSIONS: In the subjects that received isoflurane, its use was associated with significant decreases in propofol and hydromorphone infusions.
