Intrapleural Urokinase for Retained Hemothorax
This trial is active, not recruiting.
|Sponsor||National Taiwan University Hospital|
|Start date||May 2010|
|End date||August 2013|
|Trial size||32 participants|
|Trial identifier||NCT01134237, 200908047M, NTUH. 99-N1457|
Intrapleural thrombolytic treatment with urokinase for retained hemothorax is effective and safe. However, previous study was limited in prospective observation study without control group.
|Intervention model||parallel assignment|
|Masking||double blind (subject, caregiver, investigator)|
arm of interest
Normal saline as a placebo for control arm
time frame: about 5 days
Male or female participants at least 18 years old.
- Retained hemothorax: it is defined as chest X-ray revealing obvious blood clot in pleural cavity after tube thoracostomy drainage for 3 days. The chest tubes are in good location and have no obstruction. The physician thinks the blood clot is difficult to drain.
- Age: full 18 year-old
- Active bleeding
- Coagulopathy, e.g. congenital or acquired coagulation abnormality, platelet count less than 100,000 /μL, international normalized ratio (INR) more than 1.5, or partial thromboplastin time, PTT, more than 50 seconds after treatment.
- Cerebrovascular accident within 30 days
- History of intracranial tumor or vascular abnormality
- Have received thoracic surgery
- Have received pleurodesis
- Wish to receive thoracoscopic surgery for hematoma evacuation directly
- Allergy to urokinase
- People who are less than 18 years of age, prisoners, aborigines.
|Official title||Intrapleural Thrombolytic Treatment With Urokinase for Retained Hemothorax: A Prospective Double-blinded Randomized Multicenter Study|
|Principal investigator||Chin-Chih Chang, MD|
|Description||We will recruit 32 patients in this study. The patients with retained hemothorax will be randomly divided into the urokinase group and the placebo group. In the urokinase group, urokinase 100,000 IU in 100 mL NaCl will be injected into the intrapleural space. We will record the daily drainage amount and evaluate the therapeutic effect by the chest X-ray. The therapeutic effect, safety, hospital stay, and medical cost between the two groups will be compared. This study will be done in four medical centers in northern Taiwan.|
