Jason Y1 - 2021 N1 - T2 - The Atlas of Emergency Medicine, 5e AB - Many commercial devices can deliver liquids and gases at pressures exceeding 5000 psi. Unfortunately, these may accidentally introduce these substances into the body, leading to possible ischemia because of direct chemical irritation, venous outflow obstruction, arterial compression secondary to the volume of material, spasm, or edema. The injected material spreads along fascial planes, so the extent of injury can be quite misleading and is often subtle on initial presentation. Swelling and pain increase over time, but on initial evaluation, the examiner may find no apparent skin break or only a small puncture wound.
