On December 4, a little more than 2 years old baby came, a little bit of blood vessels in the elbow can not be felt, but the child to chemotherapy, can only be placed under ultrasound PICC tube. Although the child was very small, he was very well behaved, and he was afraid, but he only cried softly. It was so heartbreaking to see the child’s tears of aggression in his eyes, so heartbreaking that he did not make a fuss and did not move. When the child left, he said “Thank you, Grandma” in a childish voice. This child is half of the credit for the success of our tube placement.
