"Yeah." The old lady recognized the familiar voice and responded with her mouth.

Doctor Shi Xu, who was standing opposite, glanced at Xie Wanying, probably thinking: female medical students are gentle and considerate, and their voices are so soft.

The old lady listened to Xie Wanying's voice as if it were a lullaby and was about to fall asleep again.

After comforting the patient, Xie Wanying put on a mask and gloves, ready to assist Teacher Sun at any time.

Sun Yubo has always been very confident in Xie's work in communicating with patients. Without checking whether the patient is ready, he puts on surgical gowns, masks and gloves, turns around, and it's ready to start.

First, disinfect the surgical site. Like other surgeries, disinfect a larger area than the surgical site, then lay a drape and gently wipe off the excess disinfectant on the puncture site with gauze.

Take the syringe, draw out the mixture of lidocaine and saline, and start giving the patient local anesthesia.

Sun Yubo was an expert at applying local anesthesia and he quickly completed it. For the next puncture, he used his gloved fingers to touch the puncture point to confirm it again and again.

Doctor Shi Xu looked at his action and seemed calm on the surface, but in fact, there was some dissatisfaction in his eyes.

...

...

Once again, it was shown that the doctor in the General Surgery Department II was decisive and did not like to procrastinate, even though he looked quite gentle on the outside.

Feeling that the senior doctor opposite was getting a little impatient, Sun Yubo did not dare to hesitate. He grabbed the puncture needle, adjusted his breathing, and suddenly the needle pierced the skin at the puncture point.

Logically, after the needle is inserted into the puncture point, it will first touch the clavicle, and then go down to the subclavian vein. If blood returns when entering the vein, it means that the puncture is successful.

Everyone looked with wide eyes, and a medical student whispered, "The blood is coming back."

No, it’s not recovering blood, it’s bleeding!

When he saw that the blood in the syringe was bright red instead of dark red, Sun Yubo quickly pulled out the puncture needle. Beside him, a hand holding a piece of gauze was trying to help him suppress the gushing arterial blood at the puncture point.

The needle went into the wrong artery, the most common misoperation.

Taking a breath and adjusting his breathing, Sun Yubo felt that his face was very hot, but his fingers were very cold, almost shivering. He didn't need to look to know how Dr. Shi Xu, who was standing opposite him, would look at him coldly.

But in fact, Shi Xu didn't look at him much. He tilted his head to look at Xie Wanying, a female medical student who was pressing the puncture point to stop the bleeding.

The reason was simple. Shi Xu realized something was wrong when he was halfway through the operation. When he wanted to get some gauze to help him suppress the blood, he suddenly found that a hand took the gauze away faster than him. Yes, it was the female medical student who took the gauze away.

Without getting the gauze, Dr. Shi Xu put his hand in the pocket of his white coat and wondered: What's going on? Is this female medical student's eyesight better than his? Is it a coincidence?

After waiting for a while, Sun Yubo did not hear his superior scolding him. He felt a little unbelievable. He looked up and saw Shi Xu touching his forehead with his other hand. He was surprised: Is this patient difficult to puncture? Is the superior worried about the difficulty?

"Why are you looking at me?" Shi Xu frowned when he noticed the strange look in his subordinate's eyes. Then he came to his senses and started to scold in a low voice, "Why are you looking at me when you don't do your job properly?"

The medical students watching around realized that the operation had failed. Although the medical students were surprised when Sun Yubo pulled out the needle, they wondered how the needle could be pulled out if the blood was successfully recovered.
