Use of hemoperfusion for treatment of theophylline intoxication

We review our experience in the management of patients with plasma theophylline concentrations of 30 micrograms/ml or greater. Over a two-and-a-half-year period, 22 patients (Group 1) had plasma theophylline concentrations of 37 +/- 1 micrograms/ml (mean +/- SE) and experienced no severe toxicity (i.e., ventricular extrasystoles or tachycardia, seizures, cardiovascular collapse, or death). Six patients (Group 2) took overdoses of theophylline (92 +/- 12 micrograms/ml) and one died. Eight patients (Group 3) were iatrogenically intoxicated (48 +/- 6 micrograms/ml) and three died. Six patients from Groups 2 and 3 underwent hemoperfusion and did well, except for one patient, in whom seizures developed before hemoperfusion was initiated. We conclude from this experience that charcoal hemoperfusion is a useful procedure for the treatment of theophylline intoxication because of: (1) the serious morbidity and mortality of theophylline intoxication, (2) the prevention of complications with hemoperfusion, and (3) the relative safety of the procedure. We provide tentative guidelines for the initiation of hemoperfusion for the treatment of theophylline intoxication.
