Cardiac tamponade is a medical emergency that requires urgent drainage of the pericardial fluid. Preferably, patients should be monitored in an intensive care unit. All patients should receive the following:
Volume expansion with blood, plasma, dextran, or isotonic sodium chloride solution, as necessary, to maintain adequate intravascular volume - Sagristà-Sauleda et al noted significant increase in cardiac output after volume expansion [24] (see the Cardiac Output calculator)
Bed rest with leg elevation - This may help increase venous return
Positive-pressure mechanical ventilation should be avoided because it may decrease venous return and aggravate signs and symptoms of tamponade.
Inpatient care

After pericardiocentesis, leave the intrapericardial catheter in place after securing it to the skin using sterile procedure and attaching it to a closed drainage system via a 3-way stopcock. Periodically check for reaccumulation of fluid, and drain as needed.
The catheter can be left in place for 1-2 days and can be used for pericardiocentesis. Serial fluid cell counts can be useful for helping to discover an impending bacterial catheter infection, which could be catastrophic. If the white blood cell (WBC) count rises significantly, the pericardial catheter must be removed immediately.
A Swan-Ganz catheter can be left in place for continuous monitoring of hemodynamics and to assess the effect of reaccumulation of pericardial fluid. A repeat echocardiogram and a repeat chest radiograph should be performed within 24 hours.
