Hemodialysis in an infant with propoxyphene intoxication

A 10-month-old infant was treated with intensive supportive care and hem odialysisfor severe propoxyphene intoxication. Dialysis clearance studies demonstrated that propoxyphene was removed from the serum at approximately 50% of the rate of blood urea nitrogen removal. Possibly because of tissue binding of the drug, the absolute quantity of propoxyphene removed by dialysis was small. The child survived the acute episode of intoxication but died of pulmonary complications several days later. The role of dialysis in propoxyphene intoxication remains to be established.
