When do you transfuse platelets in thrombocytopenia?
1. Platelet transfusion is indicated for patients with clinically significant bleeding in whom thrombocytopenia is thought to be a major contributory factor, even if the platelet count is >10×109/L. 2. In patients with critical bleeding requiring massive blood transfusion.
What is transfusion thrombocytopenia?
Background. Post-transfusion purpura (PTP) is a rare yet serious disease characterized by severe thrombocytopenia occurring after a blood transfusion. It is caused by alloimmunization against platelet antigens, anti-HPA-1a being the most frequent antibody.
Why platelet transfusion is contraindicated in ITP?
The therapeutic benefit of platelet transfusions in the management of ITP is controversial, as transfused platelets are short-lived, and platelet transfusion has been linked with increased risk of arterial thrombosis and mortality in platelet consumptive disorders such as thrombotic thrombocytopenic purpura and heparin …
At what level are platelets transfused?
Patients undergoing invasive procedures should have platelet counts greater than 50 X 109/L. In the hemorrhaging patient, platelet transfusion is indicated when thrombocytopenia is contributing to the bleeding and the platelet count is less than 50 X 109/L.
What rate 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 are platelets transfused?
In most cases, platelets do not need to be matched to your blood group in the same way as a blood transfusion. The platelets for transfusion are yellow-coloured and stored in small plastic bags. Platelets are given by a drip (infusion) into one of your veins.
How fast can you infuse platelets?
The transfusion usually takes 15 to 30 minutes. You may have it in an outpatient clinic, in a day unit, or as an inpatient. The transfusion increases the number of platelets in your blood straight away. But sometimes the benefits do not last long, and you may need more transfusions.
How long does a platelet transfusion last?
Platelet infusion duration The transfusion usually takes 15 to 30 minutes. You may have it in an outpatient clinic, in a day unit, or as an inpatient. The transfusion increases the number of platelets in your blood straight away. But sometimes the benefits do not last long, and you may need more transfusions.
How long is a platelet transfusion good for?
Transfused platelets have an expected life-span of 3-4 days. This may be significantly reduced due to immune refractoriness, consumption, or sequestration. Common causes of suboptimal platelet count increments include ongoing bleeding, DIC, sepsis, fever, and hypersplenism.
How long does a platelet infusion last?
What level of platelets is critical?
Dangerous internal bleeding can occur when your platelet count falls below 10,000 platelets per microliter. Though rare, severe thrombocytopenia can cause bleeding into the brain, which can be fatal.
What is the danger zone for low platelets?
Are platelet transfusions safe?
Recent findings demonstrate that the platelet count threshold for prophylactic transfusion can be as low as 10,000/µL, and a therapeutic rather than a prophylactic strategy of transfusion for bleeding manifestations only may be equally safe for most patients.
How long will a platelet transfusion last?
Can a low platelet count cause death?
If left untreated, a low platelet count can be very serious because it can cause internal bleeding of the brain or the intestines. In the worst cases, this may even cause death. That is why it is essential to seek medical care if you think you might be at risk.
How long can you survive with low platelets?
Platelet destruction Platelets live about 7-10 days in people without thrombocytopenia. A low platelet count can be a result of the body destroying too many platelets too quickly.

When to transfuse platelets?
§: The indication for platelet transfusions in surgical patients with a platelet count between 50,000 and 100,000/mL is based on the overall risk of bleeding, which is related to the type and extent of the operation, the ability to control intraoperative bleeding, the consequences of uncontrolled bleeding and the presence of factors that can affect platelet function (extracorporeal circulation, renal failure, drugs) and/or other comorbid conditions.
How fast to infuse platelets?
This parenteral agent achieves steady state concentration within minutes and platelet function recovers within 2 h after the infusion is discontinued. [32] A key observation made during the
What is the correct tubing for platelet infusion?
• RBCs, platelets and plasma must be transfused through blood tubing with a 170 to 260 micron filter to capture any fibrin debris • Blood tubing/filter may be primed with blood or with compatible IV fluid (0.9% sodium chloride) • Blood tubing/filter must be changed after a maximum of 4 units of blood or 4 hours of time
