how is a bone marrow aspirate taken?

Answer 1

They drill into your pelvic bone and aspirate (suck out with a syringe) the marrow. Hurts like hell, but you're saving a life. They have less painful procedures now though.

Answer 2

The site of puncture is cleansed with an antiseptic solution, and you are given a local anesthetic at the area. The site may be the pelvic bone or the breastbone.

Occasionally, another bone is selected. Then, a thin aspirating needle (a needle with a syringe attached that will create a suction) is inserted, and a small sample of the bone marrow fluid is withdrawn. The fluid is placed on a slide for microscopic examination.

Answer 3

The doctor taking your bone marrow aspirate will discuss all this with you.

Generally speaking

- obtain consent
- clean the area to be used (hip/sacrum/sternum) and make it sterile
- inject a local anaesthetic to numb the area
- use a needle to enter the bone into the marrow and syringe to suck out some marrow
- take needle out
- put a small dressing (big bandaid) over the area
- sample to the lab

something like that

Answer 4

It depends on where it'll be taken from. One way is to open the end of one of the long leg bones and use a powerful suction-connected syringe to remove a sample of the forming blood cells inside.
