EnWe analyzed epidemiologic and clinical characteristics, treatment received, and clinical course in cases of pepper spray injury treated in the chemical decontamination area of an emergency department over a 5-year period. A total of 15 patients with a mean (SD) age of 25 (8.3) years were included. Thirteen were men and 53% were foreign-born. All uses of pepper spray occurred during muggings that to place mainly in the early hours of the morning (66.7% between 4:30 and 6:30 AM). Two or more attackers were injured in 60% of the events. Seventy-three percent of the attacks took place on the street and the median delay in reaching the emergency department was 30 minutes. The face and eyes were usually injured, and symptoms included itching, irritation, burning, and pain. On arrival, the patients were treated immediately (mean delay, 3 minutes) with hypertonic saline, an amphoteric surfactant, and a chelating agent in 80% of the cases, in which improvement was substantial as mean pain scale scores changed from 7.2 on admission to 3 on discharge (P=.009). Patients spent an average of 40 minutes in the treatment area. Eleven patients required further care from an ophthalmologist and topical medication for symptoms. Outcomes were good and there were no complications in any of the cases. We conclude that pepper sprays are being used as an aid to self defense in muggings in our community. Decontamination measures have priority as they alleviate symptoms and prevent long-lasting effects.
