Calcium-current facilitation in chromaffin cells

A case of severe, acute accidental theophylline intoxication in a 6-week old preterm infant treated with peritoneal dialysis is reported. Theophylline concentrations in plasma, urine and in the peritoneal lavage fluid were measured during all the procedure. With dialysis theophylline half-life was reduced to 14.8 hours, despite a plasmatic peak level of 133 micrograms/ml, and a significative amount of the drug was removed from the body, leading to a rapid and complete recovery of the child. In our experience peritoneal dialysis can be regarded as a first line emergency procedure in very sick infants with severe theophylline intoxication when more sophisticated methods are not available.
