Objective
When given as a long-term infusion propofol (Disoprivan®) may cause a rare but frequently fatal complication, the propofol infusion syndrome. The hallmarks are rhabdomyolysis, metabolic acidosis and myocardial failure. It has been assumed that the pathophysiologic cause is propofol s impairment of oxidation of fatty acid chains and inhibition of oxidative phosphorylation in the mitochondria, leading to lactate acidosis and muscular necrosis. Propofol infusion syndrome has not only been observed in children.
Methods
The authors present a 21-year-old patient with an infratentorial AVM Spetzler Grading 2 who received a prolonged infusion of propofol for sedation on ICU and who developed propofol infusion syndrome with severe rhabdomyolysis and myocardial failure without metabolic acidosis. The patient has been treated for 6 days with a continuous propofol infusion (7,2 gr/24h) and began to exhibit high elevated creatine phosphokinase (CPK) (max. 28600 U/l) as a result of rhabdomyolysis. Other reasons for this elevation were excluded. A severe metabolic acidosis was missed. Rhabdomyolysis was responsive to maximum hypervolemic therapy. Acute renal failure was prevented. Myocardial dysfunction with ventricular premature complexes without haemodynamic failure was seen. It was successful treated with Cordarex® (Amiodarone). The sedation management was changed to Brevimytal® (Methohexital-Na). After decrease of the CPK to normal level the patient underwent surgery.
Results
This patient represents a case of severe rhabdomyolysis and cardiovascular disturbance without metabolic acidosis observed after a prolonged propofol infusion. The sedation management was successfully changed to barbiturates.
Conclusions
The authors suggest selection of other pharmacological agents for long-term sedation in adult patients and a careful use of propofol considering the possible side effects. In cases of unexplained high elevated CPK, lactate acidosis and myocardial failure occurring during continuous propofol infusion, propofol infusion syndrome must be taken into consideration.
