Cardiac Tamponade

What is it?

  • Fluid or air fills the pericardial sac, compressing the heart and reducing its' ability to fill and effectively pump blood

Causes, Treatment, Diagnosis

  • Pericardial tamponade may be caused by:
    • Trauma (e.g. Blunt force trauma)
    • Other medical conditions (e.g. Immune disorders, MI, CHF)
  • Treatment is pericardiocentesis (decompression of the pericardial sac) 
  • Diagnosis of pericardial tamponade is found through diagnostic tests not available in the prehospital realm (Echocardiogram)
    • Thus, this condition as a cause of arrest is essentially impossible to be identified in the pre-hospital environment 

Why Leave Early

  • In short, you will NOT: Given the difficulty in identifying cardiac tamponade in the pre-hospital setting, focus on the basics, utilizing yoru excellent quality resuscitation via the Cardiac Arrest Medical Directive
  • In the setting of trauma, follow the Traumatic Cardiac Arrest medical directive 

In Summary

  • Cardiac tamponade can occur when there is an accumulation of fluid surrounding the heart, causing it to pump ineffectively, which can result in cardaic arrest
  • Since it is impossible to find in the prehospital realm
    • Follow your standard Medical Cardiac Arrest Medical Directive employing your excellent quality resuscitation
    • In the setting of trauma, follow your Trauma Cardiac Arrest Medical Directive
