What it takes to tamponade

on 5.9.08 with 0 comments




  • pericardial space normally holds about 25 ml of serious fluid

  • as little as 100 ml, if it accumulates quickly, can do you in

  • if it chronically accumulates, you might even hold up to 1 liter before significant mortality

  • it’s not the volume but rather the rate of accumulation that is responsible for development of acute, life-threatening conditions


Causes of tamponade

  • hemopericardium

    • this is what kills people in car accidents—rip aorta, aorta bleeds retrograde

    • or, atherogenic

  • neoplasm: rapid accumulation of fluid

  • radiation therapy, infections, drug reactions (procainamide, hydralazine)
