Item Scale to assess severity in organophosphorus intoxication: POP scale(SAGE Publishing, 1993) Senanayake, N.; de Silva, H.J.; Karalliedde, L.A.We have developed a clinical scale to assess severity or organophosphorus (OP) intoxication. Five common clinical manifestations of OP poisoning have been selected as parameters, each to be assessed on a 3 point scale varying from 0-2. Poisoning can then be graded as mild (score 0-3), moderate (score 4-7) or severe (score 8-11) when the patient first presents. The scale was validated using two consecutive series of 173 patients with OP poisoning. Correlations between the scores obtained on admission and three outcome variables, namely, death, the need for ventilatory support and the dose of atropine required in the first 24 hours after admission were significant. We believe that this scale would assist in grading severity of OP intoxication at first contact and help in predicting possible outcome.Item Does pralidoxime affect outcome of management in acute organophosphorus poisoning?(Lancet Publishing Group, 1992) de Silva, H.J.; Wijewickrema, R.; Senanayake, N.Acute organophosphorus (OP) poisoning is usually treated with atropine plus cholinesterase reactivators such as oximes, but controlled trials to assess the efficacy of oximes in OP poisoning have not been done. A period when the acetyl cholinesterase reactivator pralidoxime chloride was not available in Sri Lanka gave us the opportunity to compare atropine alone for treatment of moderate to severe OP poisoning (21 patients) with atropine plus pralixodime (24 patients). Outcome, as assessed clinically, was similar in the two groups. These results cast doubt on the necessity of cholinesterase reactivators for treatment of acute OP poisoning.
