Clinically, Bone Marrow Puncture Needles Often Choose Puncture Sites

Clinically, bone marrow puncture needles often choose puncture sites:

Anterior superior iliac spine: 1~2cm above the posterior anterior superior iliac spine is often used as a puncture point, where the bone surface is relatively flat, easy to fix, and convenient and safe to operate.

Posterior superior iliac spine: located on both sides of the sacral spine and bony protrusions above the buttocks.

Fix the bone marrow puncture needle holder at an appropriate length (the iliac bone puncture is about 1.5cm, and the obese people can lengthen it appropriately), fix the skin of the puncture site with the thumb and index finger of the left hand, and pierce the needle vertically with the bone surface in the right hand, as the puncture needle After touching the bone, it rotates left and right, slowly drilling and piercing the bone. When the resistance disappears and the puncture needle is fixed in the bone, it means that it has entered the bone marrow cavity.
