Abstract
Abstract
Purpose
In critically ill patients, high sedation requirements for prolonged durations are often needed to achieve ventilator synchrony, a practice that was particularly common during the early stages of the coronavirus disease 2019 (COVID-19) pandemic. We report the successful use of phenobarbital to facilitate propofol weaning after prolonged medication exposure.
Summary
A 64-year-old male with hypertension was admitted for the management of acute respiratory distress syndrome due to COVID-19 pneumonia. The patient received high doses of fentanyl and propofol with periods of concomitant midazolam and dexmedetomidine throughout his prolonged time on mechanical ventilation. Total days of exposure were 19 for fentanyl, 17 for propofol, 12 for midazolam, and 15 for dexmedetomidine. Upon improvement in lung function, attempts to wean the patient from propofol all failed due to symptoms such as tachypnea, tachycardia, and hypertension, with symptom resolution only upon return to the previous dose. Phenobarbital was trialed for possible propofol withdrawal syndrome, allowing for a dose reduction of 10 μg/kg/min within 2 hours of the first dose without any corresponding symptoms. The patient continued to receive intermittent doses of phenobarbital for another 36 hours until propofol was discontinued. He underwent tracheostomy shortly after weaning off all sedation and was discharged to rehab 34 days after his initial admission.
Conclusion
Information concerning propofol withdrawal syndrome in the literature is limited. Our experience demonstrates the successful use of phenobarbital to facilitate propofol weaning after prolonged exposure.
