Clinical presentation and laboratory findings of organic phosphorus poisoning

This study was conducted to evaluate the demographic, causative, and biologic characteristics of patients with organophosphate (OP) poisoning who were admitted to tertiary teaching and research hospitals at 2 different universities. All patients admitted to the emergency departments of Cukurova University Hospital in Adana, Turkey, between 2001 and 2003 and the Hospital of Mustafa Kemal University in Hatay, Turkey, between 2004 and 2006 were included. The study group consisted of subjects with a mean age of 28.5+/-14.1 y (range, 14-80 y), and the maximum number of cases in the second decade of life; the female-to-male ratio was 2.2:1. In all, 27 of 43 females and 16 of 20 males were married. Most subjects (n=55) had graduated from primary school; 3 were illiterate and 5 were highly educated. A total of 36 (57.1%) subjects belonged to lower socioeconomic groups. Fifty-three patients intended to commit suicide, and 10 cases were accidental. Mean arrival time of subjects to the hospital after poisoning was 9.9+/-16.1 h (range, 1-96 h); mean Glasgow Coma Scale score was 10.2+/-2.9 (range, 3-15). A total of 19 subjects were intubated, and 4 died. A total of 59 patients recovered completely. The mortality rate (6.3%) depended on various factors such as OP compound consumed, amount ingested, time interval before hospitalization, and patients' general health. Chances for recovery were greater when the patient was hospitalized at the earliest indication. In conclusion, OPs especially affected young single females, and most cases were due to attempted suicide. Because OP poisoning is an important cause of morbidity and mortality, therapy should be started immediately to avoid undesirable consequences.
