What Researchers Did
Researchers reviewed 56 published articles on how doctors diagnose, treat, and prevent frostbite in the upper limb.
What They Found
This literature review found that current frostbite management includes early rapid rewarming, avoiding re-freezing of warmed tissue, wound dressings, and NSAIDs, with thrombolysis using rt-PA and intravenous Iloprost resulting in improved outcomes for patients. Diagnostic tools like arteriography help monitor thrombolysis treatment, technetium-99m scintigraphy supports early prognosis, and newer techniques such as indocyanine green imaging and MRI show promise for improving management. The review states that the potential role of hyperbaric oxygen therapy remains a subject of ongoing research.
Canadian Relevance
No direct Canadian connection identified.
Study Limitations
As a literature review rather than original research, this study summarizes existing publications and does not generate new clinical data or directly test hyperbaric oxygen therapy.
