Could the dose of propofol used here not have significantly contributed to the higher mortality seen in the propfol group?
The standard infusion for sedation upon the ITU - as found in the BNF - is 0.3–4 mg/kg/hour. This study used significantly greater infusion rates - 7-20 mg/kh/hour. Whilst creatine kinase levels remained similar, we must consider that propofol infusion syndrome can occur after 48 hours at a rate of 4 mg/kg/hour.
Do investigators know if (and how?) propofol infusion syndrome would present after 24 hours of propofol infusion at 20mg/kg/hour in a rat?
Whilst initially interesting, the infusion rates used here rather undercut any conclusions that can be drawn.
