Abstract The objective of this was to study the pattern of patients of organophosphorous (OP) poisoning attending Kathmandu Medical College Teaching Hospital (KMCTH). This is a retrospective study of OP poisoning from hospital records were analyzed meticulously and data extracted. Data collected were: patient's demographics, motive for poisoning, type of OP poison, arrival time, time since ingestion, patient's vitals, predisposing factors, serum cholinesterase levels, treatment given, duration of hospital stay and mortality. A total of 47 patients of OP poisoning attended KMCTH from Aug 2003 to July 2005. 22(46.8\%) cases were male and 25(53.2\%) were female. The maximum number of patients were between the age of 20-40 (33-70.2\%). Married patients outnumbered the unmarried (35/74.5\% vs 12/25.5\%). The most common motive for poisoning was suicidal, 41 cases (87.2\%). Metacid (methyl-parathion) was the most commonly used OP compounds in 32 (68\%) patients. Interpersonal marital relationship seemed to be the commonest predisposing factor, 23 cases (48.9\%). The commonest time of presentation was between 6 pm-12 midnight. 7(57.4\%) cases presented within 2 hours of ingestion of the poison. Serum cholinesterase level measured after full atropinisation was >50\% of normal level in 17 cases (36.2\%). 10 cases (21.3\%) required respiratory support. Intermediate syndrome (IMS) was observed in 3 cases. Overall mortality occurred in 3 cases (6.4\%). This study highlights the problem of OP poisoning in our region. Establishment of strict policies against the sale and availability of insecticides and pesticides which are freely available in the market is an effective way to control OP poisoning.
