Revision as of 15:33, 3 March 2021
Background
- complication of contrast-enhanced CT scanning
- may also occur from MRI, but rare given low volume used
- Ultrasound-guided IVs are at higher risk[1]
Epidemiology
- ~0.5% (range 0.13-0.68%) of cases
Clinical Features
- Swelling and/or blistering at injection site
Differential Diagnosis
Contrast induced complications
- Contrast induced allergic reaction
- Contrast-induced nephropathy
- CT contrast media extravasation
- Nephrogenic systemic fibrosis
Evaluation
- Clinical (if no complication)
Management
- Stop infusion immediately
- Remove IV canula
- Ice pack to affected area
- Elevate
- Consider hyaluronidase[2]
Complications
- 97% have minimal or no injury
- 79% have localized swelling after extravasation
- 24% had pain
- 8%
- Large volumes (> 50 mL) of high-osmolar contrast media = highest risk
- skin ulceration
- soft-tissue necrosis
- compartment syndrome
Disposition
May discharge after 2 hours with precautions if no signs of complications
