Background
- Accidental digital self-injection of epinephrine from an EpiPen.
Clinical Features
- Puncture wound with delayed capillary refill (vasoconstriction)
Differential Diagnosis
- Injection of other medication
- Retained foreign body
- Allergic reaction
- Cellulitis
Evaluation
- Typically a clinical diagnosis (no testing required)
Management
- Observation for 2 hours after injection[1]
- If continued ischemia symptoms after 2 hrs, inject phentolamine into the ischemic area (see procedure below)
Digital Phentolamine Injection Procedure[2]
Equipment Needed
- 10cc syringe

- Dilute 1.5mg of phentolamine mesilate in 1mL of 2% lidocaine.
- Inject subQ into the site and stop when tissue turns pink again.
- Observe and repeat as necessary.
Disposition
