Subcutaneous injection of heparin sodium injection spacing

Studies have shown that the abdomen is divided into four quadrants by using the midpoint of the patient's umbilical cord as a cross line. The abdominal wall of the patient is injected from left to right, from top to bottom, and the four quadrants are rotated clockwise. The interval is greater than 2cm, which can reduce the incidence and area of subcutaneous bleeding.
