Abstract: Objective:To study the influence of r-tPA and urokinase in curative effect and thrombolysis time on patients with acute and severe pulmonary embolism after interventional thrombectomy. Methods: After reviewing and analyzing the clinical data of 19 acute and severe pulmonary embolism patients, we classified them into two groups in accordance with the application of r-tPA and urokinase to compare the changes of their heart rate, blood pressure, pulmonary arterial pressure, arterial partial pressure of oxygen and hemachrome before and after thrombolysis, as well as the thrombolysis effect time the two groups took. Results: The heart rate, blood pressure, pulmonary arterial pressure, arterial partial pressure of oxygen of the patients in both groups gained remarkable improvement after operation (P<0.05); the pulmonary arterial pressure of the r-tPA patient group dropped but not significantly compared with that before operation (P>0.05); the pulmonary arterial pressure of the urokinase patient group dropped significantly compared with that study before operation (P<0.05); the hemachrome of both patient groups did not significantly drop after operation (P>0.05); the thrombolysis effect time by adopting rtPA was remarkably shorter than that caused in thrombolysis by adopting urokinase (P<0.05). Conclusion: Both r-tPA and urokinase are effective in interventional thrombolysis for acute and severe pulmonary embolism. However, r-tPA could significantly shorten the time caused in thrombolysis without increasing any bleeding risk.
