About

Stingray injuries can be a hazard shared by many types of beachgoers. Stingrays often lie in the sand and when stepped on by the unsuspecting beachgoer their tail snaps foreword, resulting in a barbed stinger injecting venom into the victim. Little exists in the current literature on the natural history of stingray injuries. Most of the existing literature looks at the incidence of stings, and to a certain extent the demographic of people who seek care. To our knowledge no study has attempted to collect a more inclusive population of those people who are stung and follow them prospectively to determine the incidence of medical intervention, infection, etc.

This study aims to describe and quantify the natural history of stingray injuries and to better understand their time course and medical requirements. The study setting will be Seal Beach, which reports some of the greatest number of annual stingray injuries for any single beach on the pacific coast. Participants will be identified by the Seal Beach lifeguards who are believed to treat the majority of stingray injuries suffered at the beach. Eligible persons will be consented for participation over the phone by research personnel. If enrolled in the study they will receive a phone call by research personnel one week and one month after the injury that will collect information about the symptoms they have experienced and the medical interventions they have received, if any. This study is strictly observational in nature and will not involve any interventions on the part of study personnel or alter the manner in which or types of medical assessments or treatments.
