The intraoperative evaluation of ultrasound was becoming more and more widely used in the operating theater.

Ling ran had previously used intraoperative ultrasound frequently during surgeries. Now that he was performing heart surgery, intraoperative ultrasound was still as smooth as ever.

This was also the current trend. The area of the valve opening, the degree of movement, the degree of valve regurgitation, the speed of blood flow, the location and severity of the lesion, and so on could be judged by ultrasound.

Zuo Cidian watched Ling ran do it and craned his neck to look. He did not hide the concern on his face.

“You Know Him?”The circulating nurse walked over and stopped Zuo Cidian a little to prevent him from getting too close and affecting Ling ran’s operation.

“Just my patient.”Zuo cidian retracted his neck. It was a little slow, like a cultured turtle.
