Key result
Propofol doses as low as 2.6 mg/kg/h linked to fatal propofol infusion syndrome.
Why the study?
Propofol infusion syndrome is typically associated with high infusion rates, but its occurrence at low infusion rates in critically ill patients with risk factors is not well documented.
Population
1 24-year-old male athlete with spinal injury, ARDS, and SIRS
Comparison
Propofol sedation at low infusion rate with concurrent steroids and catecholamines

May warrant vigilance for fatal PRIS at low propofol doses in high-risk patients; single case leaves open need for revised safety thresholds.
Case Report (n=1)
No
Propofol infusion syndrome can occur at infusion rates well below the currently recommended maximum of 4.8 mg/kg/h in patients with risk factors such as ARDS, SIRS, and concurrent high-dose steroids or catecholamines.
Merz et al. (2006) conducted a case report in Propofol infusion syndrome (n=1). Propofol was evaluated on Propofol infusion syndrome (fatal). A 24-year-old male developed fatal propofol infusion syndrome despite receiving a low maximum propofol infusion rate of 2.6 mg/kg/h, suggesting risk at doses currently considered safe.
