   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.

  I saw that the old lady listened to Xie Wanying's voice like a lullaby, and was about to fall asleep again.

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

   Sun Yubo has always been very relieved about Xie's work in communicating with patients. No need to see if the patient is ready, put on the surgical gown, mask and gloves, turn around, and you can start.

   Sterilize the surgical site first. Like other operations, the disinfection is larger than the surgical site to a certain extent, and then a hole towel is covered, and the excess disinfectant on the puncture site is gently wiped off with gauze.

  Take a syringe, draw lidocaine and normal saline, and start giving the patient local anesthesia.

  Sun Yubo is familiar with local anesthetics, and he will be ready soon. For the next puncture, his gloved fingers touched the puncture point again and again to confirm.

  Doctor Shi Xu looked at his actions. He seemed calm on the surface, but he was actually a little dissatisfied.

   Once again it shows that the doctor of Puwai Er is vigorous and resolute.

   Feeling that the superior doctor on the opposite side was a little impatient, Sun Yubo didn't dare to hesitate, grabbed the puncture needle, adjusted his breathing, and the needle pierced the skin of the puncture point abruptly.

  Accordingly, after the needle is inserted into the puncture point, it will first touch the clavicle, and then go down to the subclavian vein. There will be blood back into the vein, which means the puncture is successful.

   Everyone opened their eyes and looked around, and a medical student shouted, "Blood has returned."

  No, it's not blood, it's bleeding!

   Seeing that the blood poured from the syringe was not dark red but bright red, Sun Yubo quickly pulled out the puncture needle. Beside him, he held a gauze block in one hand and tried hard to help him suppress the gushing arterial blood at the puncture point that was pulled out.

  The needle was threaded into the subclavian artery, which is the most common misoperation.

   Panting and adjusting his breathing, Sun Yubo felt that his face was hot, but his fingers were cold, so cold that he was shivering. You don't need to look to know how Dr. Shi Xu, who is standing across from him, is going to treat him coldly.

   In fact, Shi Xu didn't pay much attention to him. It was Xie Wanying, a female medical student who turned her head and looked at the pressure puncture point to stop the bleeding.

The reason for    is very simple. Shi Xu watched him halfway through and realized that it was wrong. When he wanted to get a gauze block to help him pressurize his blood, he suddenly found that a hand took away the gauze faster than he moved. Yes, the female medical student took the gauze block.

   Didn't get the gauze block, so Dr. Shi Xu put his hand in the pocket of his white coat and thought to himself: What's going on? This female medical student has faster eyesight than him? Coincidence or?

   After waiting for a while, Sun Yubo didn't hear his superior scolding him. He felt a little weird. He looked up and saw Shi Xu's other hand touching his forehead. Are your superiors feeling troubled and troubled?

   "What do you want me to do?" Seeing the strange look in his subordinate's eyes, Shi Xu frowned, and then he lowered his voice and scolded, "If you don't do well yourself, what are you looking at?"

   The medical students who were onlookers saw this and realized that the previous operation had really failed. Although the medical students were surprised when Sun Yubo pulled the needle out, they wondered how the needle was pulled out after the blood was recovered successfully.
