Pralidoxime in organophosphorus poisoning

JNMA J Nepal Med Assoc. 2010 Oct-Dec;50(180):300-2.

Abstract

Introduction: Pralidoxime are enzyme reactivator that are known to reactivate the phosphorylated acetylcholinesterase by binding to the organophosphorus molecule. The use of oximes in acute organophosphorus poisoning has been a controversial subjects for over two decades. This study was conducted with the objective to find out the estimation of serum cholinesterase and use of pralidoxime in organophosphorus poisoning.

Methods: A prospective analysis of all organophosphorus poisoning cases presented at the Emergency Department, Tribhuvan University Teaching Hospital for seven months was done.

Results: Out of 26 cases about 60% of poisoning cases were monitored for pseudocholinesterase level. About 50% of them had pseudocholinesterase level within normal limit and 20% had less than 10% of normal value. Only 33% cases with pseudocholinesterase level less than 10% were treated with pralidoxime.

Conclusions: The initial dose of Pralidoxime used was 1 gm followed by maintenance dose of 500mg 6 hourly, the doses prescribed were less than WHO recommended doses.
