Abstract
This study aimed to review the presentation and management of patients with organophosphate poisoning admitted to the four tertiary teaching hospitals in Perth, Western Australia, over a 10-year period. The case notes of all 69 patients admitted with a discharge diagnosis of organophosphate poisoning were reviewed. Twenty-two of 25 patients (88%) attempting suicide were admitted to Intensive Care Units (ICUs), with a mean stay of 7 days (range 1–25 days). All but one were men, and two died. The 44 patients with accidental exposure were mainly children and had a mean stay of 2 days, with only seven going to the ICU. All survived. Complications overall included respiratory failure, convulsions, and aspiration pneumonia. Intubation and ventilation were required in 11 patients (16%), with a mean ventilation duration of 6 days (range 1–25 days). We conclude that deliberate ingestion of organophosphates is considerably more toxic than accidental exposure. Men aged 30–50 years were the most likely to attempt suicide with these agents and had prolonged ICU admissions with significant complications and mortality.
