Precautions After Bone Marrow Aspiration Needle Extraction:

1. Pressurize the puncture site with a sand bag and lie down for 2 to 4 hours. Try not to get out of bed during the process until the medical staff confirms that there is no bleeding at the puncture site.

2. If there is continuous bleeding during the pressurization of the puncture site, for example: blood oozing from the gauze covering the wound, rapid heartbeat, difficulty breathing, cold limbs, etc. Immediately notify the medical staff in the above situations.

3. The gauze covering the puncture site should be removed after 24 hours by medical staff or by yourself, without changing the dressing; the dressing site should be changed depending on the wound condition. Do not do strenuous activities within 24 hours to avoid bleeding, and take a bath on the same day to avoid getting the gauze wet to reduce the occurrence of infection.

4. The medical staff should be informed in the following situations: (1) The puncture site still has severe pain or sudden bleeding more than 24 hours after the examination. (2) Redness, swelling, heat, pain or exudate at the puncture site. (3) Fever and chills.

5. One week after the examination, the doctor will inform the examination results. Non-inpatients, please register and return to the outpatient clinic to confirm the examination report.
