Abstract
Purpose: To compare the ventilatory and clinical outcomes associated with a fixed-dose cisatracurium infusion versus a titrated infusion strategy in patients with Acute Respiratory Distress Syndrome (ARDS). Materials and methods: Single-center, retrospective, cohort study in a medical ICU of a tertiary care academic medical center. Adult patients ≥18 years old with a continuous infusion of cisatracurium for ≥12 h for treatment of ARDS were included. The primary outcome was the PaO2 /FiO2 ratio assessed at 24 and 48 h following cisatracurium initiation. Secondary outcomes included amount of average dose of drug administered, 28-day ventilator-free days, LOS, and hospital mortality. Results: 167 patients were included; median baseline PaO2/FiO2 was 97 (76–146), median SOFA score of 9 (7–11), and ICU mortality was 71/167 (43%). In a mixed-effects model, fixed dose and titrated cisatracurium associated with similar changes in PaO2/FiO2 assessed at 24 and 48 h (p = 0.316). Fixed-dose was associated with a >3-fold increase in drug exposure (average dose 6.4 (5.4–8.0) vs. 2.0 (1.5–2.8) mcg/kg/min; p < 0.001, respectively). No differences were observed in secondary clinical endpoints. Conclusion: Fixed-dose cisatracurium was associated with similar ventilatory and clinical outcomes compared to titrated strategy, yet it was associated with a 3-fold increase in dose administered.
