A Controlled Trial of a Prostacyclin and rt-PA in the Treatment of Severe Frostbite

Abstract
Many alternatives have been proposed for the treatment of frostbite: hemodilution, platelet-aggregation inhibitors, low-molecular-weight heparin, alpha-adrenergic vasodilators, calcium-channel inhibitors, nonsteroidal antiinflammatory agents, prostacyclin analogues, fibrinolytic agents, and hyperbaric oxygen. None have been assessed in prospective randomized trials. Small retrospective studies1-3 suggest the efficacy of thrombolysis or prostacyclin analogues against spasm and thrombosis.
