Benefit of Hemoperfusion in Acute Theophylline Intoxication

Abstract

Charcoal and resin hemoperfuslon or hemodialysis can accelerate theophylline elimination. Their benefit In the treatment of poisoned patients has been accepted on the basis of case reports. We reviewed the treatment of 26 patients with acute theophylline Intoxication to determine how much of an effect hemoperfuslon or hemodialysis had on the hospital course and outcome of the overdose. Eighteen patients received supportive care and eight patients hemoperfuslon (HP) or hemodialysis (HD). The HP/HD patients had more severe theophylline Intoxication on the basis of admission and peak theophylline levels, degree of hypotension and occurrence of arrhythmias. During HP/HD, theophylline concentrations decreased, heart rate slowed, blood pressure Increased and evidence of central nervous system effects diminished. Despite the severe Intoxication In the HP/HD groups, duration of clinical toxicity was shorter (13.5 ± 7.1 vs. 21.6 ± 14.1 hr) than In the control group. Seizures occurred In patients In both groups, but there was higher mortality or neurological morbidity In the supportive care (3/4) than In the HP/HD (1/5) group. Our study provides evidence that HP/HD can reduce the duration of clinical intoxication and probably reduces mortality and morbidity In patients with severe theophylline Intoxication.
