Title: Efficacy and Safety Evaluation of 12-h and 2-h Urokinase Regimes in the Treatment of Pulmonary Thromboembolism: A Multi-Center, Randomized Controlled Trial in China
Brief Summary: Comparative trials of urokinase (UK) for 12 hours（UK-12h）or 24 hours (UK-24h) have produced similar results in acute pulmonary thromboembolism (PTE) thrombolysis. It is unclear whether the infusion time can be reduced further. The aim of this study was to investigate the efficacy and safety of weight adjusted dosage of UK-2h (20 000 IU/Kg) regime with the Uk-12h regime in selected patients with PTE in Chinese population.
