Bone Marrow Aspiration

Sampling of bone marrow, usually from the iliac crest or sternum, to check blood cell production.

Lateral Decubitus Position

Lying on the side

Prone Position

Study Notes

Bone marrow aspiration involves specific positioning based on the aspiration site
For posterior iliac crest aspiration, position the patient in either lateral decubitus or prone position
For anterior iliac crest or sternum aspiration, position the patient in the superior position
In infants, the tibia can be used as an aspiration site because it is more accessible
When using the lateral decubitus position, position the patient on their side with the iliac crest up

Description

Proper patient positioning is crucial for successful bone marrow aspiration. The posterior iliac crest requires lateral decubitus or prone positioning. The anterior iliac crest or sternum requires a superior position. Infants may have the tibia used due to accessibility.
