High Pressure Injection Injuries:
- These injuries initially often have a pretty benign appearance which may result in the injuried person seeking medical treatment late, or the initial medical provider not recognizing the seriousness of the injury.
- Even when treated promptly and aggressively most patients will end up with an amputation of thier finger or have permanent loss of funciton, strength, sensation, or chronic pain.
- In a couple of hours, these injuries tend to result in significant swelling that can lead to compartment syndrome. The swelling can be due to the actual disruption of cells from the high pressure, or due to toxic effects of the injected agent.
- Initial Management should consist of:
- X-rays: Help to evaluate the extent of the injection. Radio-opaque solvents will be seen on x-ray, but even radio-lucent solvents may be seen as lucency or air on the x-ray
- Broad Spectrum antibiotics to prevent infection
- Corticosteroids to decrease the inflammatory response brought on by the injected agent
- Tetanus Prophylaxis if needed
- Emergent hand surgery referral
- Most if not all patients will require emergent debridement of the affected area.
