The child is placed in a supine position, the arms are placed next to the body, and the lower jaw is slightly raised to expose the sternum (the infant is assisted by the assistant to fix the body, the doctor is located on the right side of the child, and the second rib plane (sternum angle) is 0.5 on the midline of the sternum. The puncture point is at cm-1cm.
Routinely disinfect the drape without local anesthesia. Connect a 10ml disposable syringe to the No. 8 needle. Tighten the skin on the left and right sides of the puncture point with the thumb and index finger of the left hand. Hold the injection needle with the pen in the right hand and face the child’s head obliquely. , And pierce into the sternum at an angle of 45-60 degrees. The force is even, no need to rotate. Generally, the 0.2cm-0.5cm needle can penetrate the bone texture. At this time, the needle body has been fixed on the sternum, and the syringe needle is pulled out, it can be seen that the marrow fluid flows out, and the bone marrow fluid is drawn to the required amount, and then the disposable syringe Pull out together with the needle, gently push the needle core to drop the bone marrow liquid on the glass slide.
This method is better than traditional methods. We realize that switching to this technology has the following advantages:
1 The needle is thin, has little damage to the tissue, does not require local anesthesia, and has a high one-time success rate. The child suffers little pain and is popular with doctors and children. 2 The method is simple and easy, and the entire operation takes only a few minutes:
3 The needle is short and the bone marrow fluid is not easy to coagulate:
4 Disposable syringes, no need for disinfection procedures to avoid cross-infection;
5 Hold the syringe to insert the needle in a pen-holding style, and do not rotate it left and right. It can better control the depth of the needle and ensure the safety of the puncture process. 6 It is suitable for children of all ages.
In short, this method has the advantages of easy operation by doctors, little pain in children, high success rate, satisfactory selection of materials, and repeated puncture for cases that need to be reviewed. It is significantly better than traditional bone marrow puncture methods and is worthy of promotion.
