The infant is fixed in position with the help of an assistant. The doctor is located on the right side of the child. The puncture point is -1cm. Routinely disinfect the drape without local anesthesia. Connect a 10ml disposable syringe to the No. 8 needle. Tighten the left and right side skin of the puncture point with the thumb and index finger of the left hand. Pierce into the sternum at an angle of 45-60°, uniform force, and inadvertent rotation. Generally, the needle is inserted 0.2cm-0.5cm to have a penetrating bone texture.
