Determine blood group and type A B Rh |
|
|
Individual with Rh- exposed to Rh+ blood |
Antibodies to the antigens could be produced |
|
|
Individual with Rh+ |
Can be exposed to Rh+ or Rh- blood without any problems |
|
|
Blood rules |
•Rh- exposed to Rh+ = antibodies to the antigens could be produced •Rh+ exposed to Rh+ or Rh- blood without any problems •Rh is primarily important in females of childbearing age •O- is the universal donor for red blood cells •AB+ is universal recipient |

|
WBCs |
White blood cells Aka leukocytes Responsible for protecting guuuur body from invasion by foreign substances such as bacteria, fungi, and viruses |

|
Whole blood considerations |
•use of straight line or Y tubing IV set with micro filter •large bore IV catheter • NS most often used to initiate the infusion of whole blood • LR used by some centers • Assess for Hx of transfusion reaction •Pt may req pre medication with antipyretics and antihistamines prior to start •allow 30 to 60 min for oral meds and 10 min for IV meds •blood cannot be returned to blood bank after 30 minutes of warming to room temp •blood warmed to prevent hypothermia •monitor pt receiving Lg volumes of whole blood for hypocalcemia (citric acid in whole blood binds calcium) |
|
|
PRBCs |
Can be administered wide open in critical situations of hypovolemia |
|
|
FFP |
Fresh frozen plasma Can be infused as quickly as pt tolerates. Should be given within 6 hrs of thawing Pts must be ABO compatible |
|
|
Blood IV catheter size |
Don't use smaller than 20g |
|
