Do platelet transfusions need to be cross matched?
A cross-match is usually not needed for a platelet or plasma transfusion unless the platelets look like they could contain some red blood cells.

How much does 1 unit of random donor platelets increase platelet count?
Platelets (Apheresis) 1 unit will increase platelet count ~ 24,000-35,000/μl (average size adult **). Provide platelet count when ordering, if available. Units usually issued within 2 hours of order receipt (routine) or to arrive by the specified date/time.
How many units of platelets does it take to transfuse?
 So, now many hospitals and physicians use platelet counts of 10,000 or 5,000 / μl as the indication for transfusion to uncomplicated patients. However, if the patient is febrile or septic, the old trigger of 20,000 / μl should be used.
What is the cross matching protocol for platelets?
A platelet cross-matching procedure has been assessed for selecting compatible donors for alloimmunized patients. This confirms the clinical value of combining an indirect platelet immunofluorescence test (PIFT) with a lymphocytotoxicity test (LCT) in predicting the survival of single-donor platelets.
Do platelets need to be group specific?
When considering a platelet transfusion, one must consider the ABO compatibility of the platelets themselves, as well as the accompanying plasma. Platelets, like red blood cells (RBCs), express ABO antigens, although expression is variable and strongly expressed in only 4% to 7% of individuals.
Which is better SDP or RDP?
Conclusions: Post-transfusion increments were significantly higher in patients who received SDP as compared to RDP, but the CCI and PR were comparable in both groups of patients.
How fast do you infuse platelets?
A transfusion rate of 2 to 5 ml/min is used, thereby completing the transfusion in 1 to 2 hours. Slower flow rates are used in patients at risk of fluid overload.
How do you prepare a single platelet donor?
Single Donor Platelets The platelets are collected and stored in a special bag which allows for gaseous exchange; while the rest of the blood (that is red cells and plasma) is returned to the donor. This constitutes one cycle. To make one unit of platelets the machine performs 6-8 cycles, each lasting about 10 minutes.
Does platelet transfusion require same blood group?
ABO identical platelets In an ideal world with unlimited resources, platelet transfusions would be ABO identical to the recipient and obtained from RhD-negative donors when the recipient is RhD negative.
Do platelets have to be matched?
Most patients don’t require human leucocyte antigen compatible platelets, but a very small group of patients need their platelets to be specially matched. These patients have human leucocyte antigen antibodies in their blood that can destroy transfused donor platelets.
What rate do you infuse platelets?
Can a+ donate platelets to O+?
Preferred donation methods: platelet and whole blood. Only types A and AB+ can receive type A+, but A+ platelets can go anywhere (except childbearing aged females of types O-, A-, B- and AB-). Type A+ can receive types A, O+ and O-.
How many RDP is equal to SDP?
Random Donor platelets (RDP) are prepared from donated blood with in 4 to 6 hrs of collection by centrifugation & it contains approximately 5.5 x 1010 platelets. Single Donor Platelets (SDP) are prepared by platelet aphaeresis machine. One unit of SDP is equivalent to 5 to 10 units of RDP.
How is SDP taken?
SDP Donations This donation entails a specialised collection process where an automated cell separator machine is used to separate and collect platelets from whole blood. This procedure is known as plateletpheresis and an aphaeresis machine separates the SDPs.
How fast do you run platelets nursing?
The infusion time should not exceed 4 hours. Platelets, plasma and cryoprecipitate generally are transfused at a rate of 10 ml per minute. In order for a patient to receive maximum benefit platelets need to be transfused rapidly to get control of bleeding.
