Abstract |
The most common cause of acute drug intoxication in Korea is organophosphate
intoxication. Organophosphate suppresses cholinesterase activity; leading to unique clinical
features by stimulating of muscarinic and nicotinic receptors and central nerve system symptoms.
In the present study; major complications and risk factors of mortality were analyzed to predict
clinical outcomes of patients in organophosphate intoxication. Among 84 patients who visited
Kyungbook University Hospital's emergency medical center due to organophosphate from Jan.
2000 to May 2006; the medical records of 70 patients were analyzed retrospectively. Fourteen
patients were excluded because they were transferred to other hospitals or discharged against
medical advice during treatment. Among the various variables; mortality rate was significantly
increased in cases of patients over 70 years old (p<0.05); hypotension (p<0.05) and bradycardia
(p<0.05) at presentation and acute renal failure (p<0.001) during treatment. In logistic regression
analysis; old age over 70 years (p<0.05) and acute renal failure (p<0.01) showed statistical
significance. Old age and acute renal failure were poor prognostic factors in acute
organophosphate intoxication. |
