Bone Marrow Aspiration and Biopsy Care

Key Points

• Bone marrow aspiration collects liquid marrow, while biopsy collects a core of marrow and bone tissue.
• Safe care includes informed-consent confirmation, sterile setup support, and close monitoring for bleeding or infection.
• Clients should be prepared for pressure and procedural discomfort and coached through the procedure.
• Post-procedure teaching focuses on site care, activity limits, and red flags that require prompt reporting.

Equipment

• Ordered procedure documentation and consent verification materials
• Sterile setup and local-anesthetic supplies per facility protocol
• Dressing supplies, pressure materials, and ice-pack resources
• Analgesic medication access (aspirin-free when ordered)
• Monitoring and documentation tools

Procedure Steps

1. Verify informed consent is complete and address any understanding gaps before the procedure starts.
2. Reduce anxiety with clear explanations, emotional support, and realistic preparation for expected sensations.
3. Prepare and maintain sterile conditions; position client prone or side-lying as tolerated and directed.
4. During the procedure, assist with local-anesthetic support and coach the client to remain still.
5. Reinforce that burning/stinging, pressure, or a crunching sensation may occur as the needle enters marrow space.
6. After the procedure, monitor for bleeding, swelling, infection signs, and other adverse responses.
7. Use ordered aspirin-free analgesia, apply ice as indicated, and apply pressure until site bleeding has stopped.
8. Reassess the site at ordered intervals (commonly every 2 hours in immediate recovery), document findings, and escalate concerning changes promptly.
9. Teach home care, symptom-reporting triggers, and activity restrictions (including trauma/contact-sport avoidance for 24-48 hours).

High-Risk Findings

• Persistent or increasing bleeding at the aspiration/biopsy site
• New swelling, erythema, drainage, or fever suggesting infection
• Worsening pain not controlled with prescribed post-procedure measures
