Slow‐release potassium overdose: Clinical features and the role of whole‐bowel lavage in management

Abstract

AbstractPoisoning with slow‐release potassium preparations is reported uncommonly in the medical literature; slow‐release potassium poisoning occurring in a child has not been reported previously. There is potential for death from hyperkalaemia, as well as significant potential morbidity from gastrointestinal side‐effects of the potassium preparations. Treatment of hyperkalaemia is paramount in stabilizing these patients, but previous reports have not strongly supported the role of vigorous gastrointestinal decontamination in the management of this overdose. We report a case of significant slow‐release potassium poisoning in a child, and discuss our management. The literature of slow‐release potassium poisoning is reviewed with an emphasis on the role and safety of gastrointestinal decontamination with whole‐bowel lavage.
