Diagnosed by Reversibility: Unmasking Propofol-Related Infusion Syndrome in a Critically-Ill Elderly Male.

Propofol-related infusion syndrome (PRIS) is an uncommon complication resulting from prolonged propofol use. Common clinical presentations include metabolic acidosis, cardiac arrhythmias, and renal complications. The mortality rate is high if it is not recognized in time. There is no antidote to propofol. Initial treatment involves discontinuing ongoing propofol use and providing supportive measures. The reversal of clinical and laboratory features upon discontinuation of propofol provides a basis for retrospective diagnosis or PRIS. In severe cases, ultrafiltration may be utilized.
