Abstract

BACKGROUND: Acute poisoning with organophosphorus compounds (OPs) is a major global clinical problem in the developing countries. There have been many animal studies and few human surveys on the effects of organophosphorus pesticide (OP) poisoning on thermoregulation. The aim of this prospective study was to document the pattern of tympanic temperature changes among OP poisoned patients throughout the length of their hospital stay.

METHODS. 60 patients with diagnose of organophosphate poisoning were included in this study. Questioner was filled out by trained nurses including demographic, clinical and paraclinical data. Tympanic temperature and Pulse rate data of the cases were collected on five- occasions after admission.

RESULTS: There were 41 (68.3%) male and 19 (31.7%) female, with a mean age of 34.4 19.4 years (range 13-89 years). Forty five patients had intentional poisoning for suicidal attempt. At the time of entry, the mean tympanic temperature, pulse rate, respiratory rate and blood pressure (systolic and diastolic) of the OP poisoned patients were respectively 37.1+/0.6°C (36.0- 39.5), 91+/18 (55-145), 18+/5.6 (8-44), 116+/20 mm Hg (70-170) and 75+/11.6 mm Hg (40-110). 41.7% of the cases had serum butyryl cholinesterase activities (BChE)50% normal (1600 mU/ml). Our patients had normal temperature at the time entry (mean=37.1). Tympanic temperature decreasing below 36°C was not detected among the patients during the study period. A rise in mean tympanic temperature was found after atropine administration.

CONCLUSION: Our study showed hypothermia was not considerable factor among organophosphate poisoned patients, although more studies with similar situations in tropical countries are needed. © 2012 Talaie et al.; licensee BioMed Central Ltd.
