I read with interest the review by Prof. Gutierrez and colleagues on hemorrhagic shock [1]. The treatment of hemorrhagic shock is addressed in the review, and mention is made of the main goals: to stop the source of hemorrhage and to restore the circulating volume.

متن کاملClinical review: Hemorrhagic shock
This review addresses the pathophysiology and treatment of hemorrhagic shock - a condition produced by rapid and significant loss of intravascular volume, which may lead sequentially to hemodynamic instability, decreases in oxygen delivery, decreased tissue perfusion, cellular hypoxia, organ damage, and death. Hemorrhagic shock can be rapidly fatal. The primary goals are to stop the bleeding an...
متن کاملImpending Hemorrhagic Shock
By blocking sympathogenic vasoconstrictor mechanisms with dibenamine, a dog's tolerance to severe hemorrhagic hypotension states is definitely improved. New evidence is presented that partial release from vasoconstriction achieved by, giving small doses of dibenamine during the impending shock state seems to provide animals with even greater tolerance to this standardized form of stress. Althou...

متن کاملInitial resuscitation of hemorrhagic shock
The primary treatment of hemorrhagic shock is control of the source of bleeding as soon as possible and fluid replacement. In controlled hemorrhagic shock (CHS) where the source of bleeding has been occluded fluid replacement is aimed toward normalization of hemodynamic parameters. In uncontrolled hemorrhagic shock (UCHS) in which bleeding has temporarily stopped because of hypotension, vasocon...
