Care of the potential organ donor
AIM
Organ perfusion and improved quality of grafts
1.Venous volume reservoir
2.Contractility
3.Arterial resistance system
1.Venous volume reservoir
Hypovolemia
Absolute hypovolemia
Relative hypovolemia
Fluid Management
1.Crystalloids
-Hypernatremia
-Hyperchloremic acidosis
used fluids : Ringer's lactate
Avoid colloids. Hydroxyethyl starches
3.Albumin solutions
4.PRC
2.Contractility
1.Cardiac dysfunction
-Preexisting disease
-Cardiac contusion
-Cardiac temponade
-Myocardial injury
-Cardiac arrhythmia
-Volume overload
Inotropes
3.Arterial resistance system
1.Vasodilatation
-Spinal shock
-Catecholamine depletion
-Loss of vasomotor control
-Endocrine failure
-Sepsis
Vasopressors
-Noradrenaline
-Monitoring
