However, they are associated with an extremely high morbidity including limb loss and asymmetric limb growth. 11 year old previously healthy female who presented to a pediatric emergency department immediately after sustaining blunt trauma to her abdomen by a bicycle handlebar. She complained of pain in her right lower extremity without paresthesia and was noted to have a painful superficial laceration to the right lower abdomen with tenderness on palpation. The extremity was noted to be mottled, cool to touch, with decreased sensations and delayed capillary refill but intact motor function. The peripheral pulses in the extremity were noted to be absent on exam, which was confirmed by a bedside Doppler. A Computed Tomography Angiography (CTA) of the abdomen and pelvis revealed an occluding thrombus in the external iliac and right common femoral arteries which required surgical repair. She subsequently developed occlusion secote lower limb ischemia as well as bedside Doppler exams and early consideration of CTA to assess for occult vascular injury. Substance-related referrals to the Emergency Department (ED) are rising. Multiple substance use is frequent, and psychiatric patients represent a high-risk population. Our study aimed at identifying risk factors for increased severity in ED attendances for substance use. We retrospectively evaluated consecutive patients attending the ED over ten years for substance-related problems, subdivided according to the triage code as having a life-threatening (LT), potentially life-threatening (P-LT), and non-life-threatening (N-LT) condition. Substance/drug intake for deliberate self-harm was a risk factor for being classified as LT compared to both P-LT (OR = 6.357; p ≤ 0.001) and N-LT (OR = 28.19; p ≤ 0.001). Suicide attempts (OR = 4.435; p = 0.022) and multiple substance use (OR = 1.513; p = 0.009) re
