Single dose of propofol causing propofol infusion syndrome in a newborn.

Propofol infusion syndrome (PRIS) is a rare syndrome originally described in critically ill children undergoing long-term (> 48 h) propofol infusion at high doses (> 4 mg/kg/h). Severe metabolic acidosis, rhabdomyolysis, renal failure and fatal cardiac failure are the features. Herein, we present a case of a newborn who developed PRIS after a single bolus dose of propofol at 3.2 mg/kg/do, developing rhabdomyolysis and severe metabolic acidosis, with a successful outcome after medical therapy.
