Objective:To explore a method for pericardiocentesis and drainage

the duration

posture of drainage and the fluid volume by drainage.Methods:Forty patients half lying on the bed

the puncture was performed via the subxiphoid route after the site

depth and direction of needle entry were confirmed by echocardiography.Using seldinger method

we put the central venous indwelling catheter into pericardial sac and connect it with an aseptic bag for drainage.Results:Catheter pericardiocentesis in 40 patients was successful without complications.Duration of use of the indwelling pericardial catheter ranged from one day to seven days

the average is 1.5±2 days.The fluid volume removed was one hundred and eighty to two thousands milliliters

mean volume is 750±600ml.After drainage

chest discomfort and short breath were alleviated obviously.Prominent jugular veins disappeared.Reductions of heart rate were significant.Cardiac function improved.Conclusion:Seldinger technique is a safe method for pericardiocentesis and drainage with the assistance of echocardiographic diagnosis and guidance.It can avoid myocardial trauma and drain the pericardial effusions effectively.
