The seventeen centimeter puncture needle passes through the belly of the pregnant woman, the uterus, the fetal intercostal space, and directly reaches the right ventricular outflow tract of the fetal heart. It needs to be done right the first time without any chance of trial and error.

The heart of a 24-week-old fetus is only about the size of an almond, and the diameter of the right ventricular outflow tract is only four millimeters.

The puncture needle cannot penetrate even more. It has to be just right. You can imagine how difficult it is...

At this time, Wang Chunyuan stared closely at Yu Zhiming's movements, not daring to be distracted in any way.

The next moment, he saw Yu Zhiming taking the guide wire and dilation balloon from the nurse and sending it through the puncture needle.

Wang Chunyuan knew that his time to show off was coming.

Just when he thought of this, he heard Yu Zhiming's voice in his ears.

"Ball, now!"

Without thinking, Wang Chunyuan pressed the pressure valve in his hand reflexively.

once!

twice!

three times!

Immediately afterwards, he relieved the pressure from the balloon.

The next moment, Yu Zhiming withdrew the balloon, guide wire, and puncture needle.

Then, the surgical nurse busily attached several sensor patches to the pregnant woman's belly.

The monitoring instruments and equipment in the operating room were turned on one after another.

The operating room and atmosphere that Wang Chunyuan is familiar with are back.

He looked at several instruments monitoring the fetus.

I saw that the data on the screen finally stabilized after a period of changes.

Fetal heart rate, 135 beats/min.

This is the normal range allowed.

Wang Chunyuan looked at the forward blood flow through the pulmonary valve shown in the ultrasound image.

Wang Chunyuan, who knew the fetus before, found that the forward blood flow increased by more than six or seven times.
Chapter completed!
