Study Details

Early identification of tissue injury from a rattlesnake bite is critical to prevent complications and reduce health care costs. Given the limitations of clinical assessment, there is a need to develop a more objective reproducible, anatomically detailed diagnostic tool for to accurately assess tissue damage and assist with timely administration of antivenom, if needed. Emergency physician performed point-of-care ultrasonography has been shown to be beneficial in the diagnosis and management of skin and soft tissue infections. The innovative use of bedside ultrasound technology can provide new information to individualize antivenom treatment and to improve patient outcomes. The objectives of this study is to compare clinical assessment and bedside ultrasound findings in the detection of tissue injury in emergency department patients with rattle snakebite and determine if bedside ultrasound can alter management (antivenom dosing) in emergency department patients with rattle snakebite.
