1. Preoperative massive transfusion and pericardiocentesis are not advocated.

2. Pericardiocentesis with a wide-Bore needle yielded no Blood.

3. Objective:To explore a method for pericardiocentesis and drainage, the duration, posture of drainage and the fluid volume by drainage.

4. Objective To investigate the clinical value of B-Us-guided pericardiocentesis .

5. Objective: To explore the method for pericardiocentesis and drainage, the duration, posture of drainage and the fluid volume in pericardial effusion patients.

6. Pericardiocentesis is a simple, safe and effective acute cardiac tamponade.

7. Pericardiocentesis is a simple, safe and effective therapy for acute cardiac tamponade.

8. Interventional Pericardiology: Pericardiocentesis, Pericardioscopy, Pericardial Biopsy, Balloon Pericardiotomy, and Intrapericardial Therapy.

9. Early recognition of pneumopericardium is important, because emergent pericardiocentesis may be required if there is clinical evidence of cardiac tamponade .

10. Objectives Retention laying vena duct drainage is an effective method to treat pericardial effusion and tamponade. We try to study the pericardiocentesis complications.

11. Acute cardiac tamponade with shock developed after pacemaker implantation in our intensive care unit,[Sentencedict] which was successfully managed by emergency pericardiocentesis as well as medical therapy.

12. Diagnosis and treatment of pericardial effusion are difficult in clinical practice. Pericardiocentesis is a important technique.

13. Conclusion B-Us is of great value in the diagnosis, pericardiocentesis and choice of treatment of pericardial effusion.
