Bone Marrow Puncture Needle

The sternum is usually not chosen for puncture. The bones of the elderly are brittle and brittle. It's a little bit more dangerous. But the posterior superior iliac spine is the most common clinical choice. The anterior superior iliac spine is next followed by the lumbar vertebra. The sternum should only be used if puncture elsewhere fails. The posterior superior iliac spine is located at the top of a large bone that is palpated on the hip. It's safer here. Out of the patient's line of sight, the psychological feeling is relatively less frightening.

For sternum puncture, the approximate location is subcervical, about 5cm below the superior sternum notch. And it's a vertical needle. This position is actually the manubrium sternum. It is followed by a large arteriovenous and trachea. Some distance from the heart.
