Early resuscitation:

  • Early resuscitation:

  • Fluid administration is the cornerstone of acute resuscitation.

  • Intravascular volume is lost because:

  • hemorrhage

  • uptake by ischemic cells

  • extravasation into the interstitial space.

  • The ATLS curriculum advocates the rapid infusion of up to 2 L of warmed isotonic crystalloid solution for any hypotensive patient, with the goal of restoring normal BP .



Fluid administration:

  • Fluid administration:

  • reduces oxygen delivery

  • hypothermia

  • coagulopathy.

  • Elevation of Blood pressure leads to:

  • increased bleeding as a result of disruption of clots

  • reversal of compensatory vasoconstriction.

  • The result of aggressive fluid administration is often a transient rise in BP, followed by increased bleeding and another episode of hypotension, followed by the need for more volume administration.

  • This vicious cycle has been recognized since the First World War and remains a complication of resuscitation therapy today.



Application of this technique to the initial management of a hemorrhaging trauma victims highly controversial and has been the focus of numerous laboratory and clinical research efforts.
