|
5L in Kg man
1000 ml lost=20% of 5L 3000ml of crystaloid (3:1 rule) |
3:1 rule is for ever liter of intravascular volume lost, 3 liters of crystaloid must be replaced.

most practical measure of adequate tissue perfusion/volume resussitation is
|
urine output (more that .5ml/kg/h is adequate)
|
|
|
|
what urine output is a sign of adequate tissue perfusion
|
.5ml/kg/h

cardiogenic and hypovolemic shock are the same in all the following parameters except:
decreased cardiac output degree of vasoconstricion oliguria mental obundation R and L filling pressure |
filling pressure high in cardiogenic shock and low in hypovolemic shock
|
|
|
|
why is blood glucose elevated in acute hemorrhagic shock
|
catecholamines increase glucagon and decrease insulin release.

70 kg man
bp=90/70 hr=130/min what stage of shock % and amount of blood loss |
stage III shock
30-40% blood loss .3to .4*5L=1500-200L blood loss |
|

|
presence of blood at the urethral meatus, perineal hematoma or abnormal prostate exam suggests what and what should be done
