Can You Infuse Platelets Through a Blood Transfusion Set?

Yes, you can infuse platelets through a standard blood transfusion set with a 170-200 μm filter, but it must be a clean set that has NOT been previously used for red blood cells. 1

Critical Equipment Requirements

The Clean Set Rule

• Platelets must NEVER be given through a set that has already been used for red cells because platelets will stick to residual red cells in the tubing, reducing the effective transfused platelet dose 1, 2
• This is the single most important pitfall to avoid in platelet administration

Acceptable Administration Sets

You have two options for platelet infusion 1:

• Standard blood administration set with 170-200 μm filter (clean, unused)
• Dedicated platelet administration set with 170-200 μm filter

Special Circumstances: Massive Hemorrhage

• In massive transfusion protocols, while a dedicated platelet giving set is ideally preferred, it is unnecessary in emergency situations 1
• The critical requirement remains: use a clean 170-200 μm giving set 1
• Best practice: Set up two separate IV lines—one for packed red blood cells and one for platelets—to avoid any cross-contamination 2

Practical Administration Guidelines

Infusion Parameters

• Infuse over 30 minutes through the appropriate set 1
• Begin transfusion within 30 minutes of removal from platelet storage incubator 1
• Never add drugs directly to the platelet unit 1

Storage Considerations That Affect Set Selection

• Platelets are stored at 22°C (room temperature), not refrigerated 1, 2
• This differs fundamentally from red cells stored at 1-6°C 2
• This temperature difference is why previously used red cell sets are problematic—the cold red cell residue can damage platelets

Blood Warming Compatibility

• Platelets can be safely infused through blood warmers without harm 1
• While greatest warming benefit is for cold red cells, there is no evidence that warming platelets through approved devices causes damage 1

Algorithm for Set Selection

For routine platelet transfusion:

1. Use a fresh, unused standard blood administration set (170-200 μm filter) OR dedicated platelet set 1
2. Ensure set has never contacted red blood cells 1, 2

For massive transfusion protocols:

1. Establish two separate IV lines if possible 2
2. Dedicate one line exclusively for platelets 2
3. If only one line available, use clean 170-200 μm set and accept that you cannot simultaneously infuse red cells 1

Common pitfall to avoid: Using the same tubing sequentially for red cells then platelets—this will result in platelet loss and reduced therapeutic effect 1, 2
