noon.

Ling Ran, who had eaten and drank enough, sat on the chair in the office, opened Xiaoyao, half-lying down and looked out the window, looking at the corner of the building in front of him, lost in thought.

The sun shines on the ground, making it warm.

On his left hand side is a cup of lemon, kumquat and passion fruit tea sent by the nurse station, with ice cubes added, making it misty and cool. On his right hand side are three small snacks given by the patient's family members.

Although receiving red envelopes is no longer allowed, patients and their families are still allowed to give food. However, most patients and their families send fruits or snacks, which are given to everyone in the department. They are specially given to a certain doctor.

This explanation only came after Ling Ran came.

"Have you eaten enough?" Huo Congjun returned to the office and saw Ling Ran recharging his energy, and nodded with satisfaction.

Ling Ran said "Yes" and asked, "Has the patient arrived?"

"Wang Haiyang is looking at the information and hasn't decided yet." Huo Congjun said and asked: "Have you bought chocolates or something like that?"

"I bought one." Ling Ran showed a large piece of Dove chocolate, which he bought in the vending machine.

"Not enough." Huo Congjun looked at it and shook his head, saying: "The operation time of replanting the severed finger may be long. What will you do if you are hungry by then?"

"I haven't heard of other doctors eating in the operating room..."

Huo Congjun curled his lips and said: "They are them. The secrets of our emergency department are to drink well and eat well before the war, to take time to eat and drink well during the war, and to eat well and drink well to replenish energy after the war... Then

Someone, give Ling Ran two Snickers bars."

A young resident doctor came delivering Snickers bars.

Ling Ran had no choice but to put it away and went out with a small snack as a gift.

Huo Congjun nodded: "When you go in, listen to Wang Haiyang and Director Wang first. He asked you to take over, and then you take over. Although they are all microsurgery, replanting a severed finger is still different."

"Quack, quack, quack, quack, quack."

Ling Ran didn't say anything, and the chair next to him was shaken and made a strange noise.

Huo Congjun and Ling Ran naturally looked over and saw Lu Wenbin sitting on the chair shaking so hard that he couldn't stop even if he wanted to.

Lu Wenbin was embarrassed by the sight, stood up suddenly, and said with a smile: "I'm just a little excited."

He is the default candidate for second assistant, and it is also his first time to participate in the replantation of a severed finger.

Huo Congjun said unhappily: "When I called you to rescue patients before, why weren't you excited?"

Are you jealous? Lu Wenbin said happily and nervously: "I was excited too, even more excited, but I didn't have time to shake at the time, so I didn't realize..."

Huo Congjun said "yes" and said to Ling Ran: "Don't go too far, come into the operating room at any time."

After thinking about it, Huo Congjun left the office.

Lu Wenbin's nervous legs were shaking now: "Did I say something wrong? What do you mean, Director Huo?"

He subconsciously looked at Ling Ran, only to see that Ling Ran was bathing in the sun, and his face was about to shine with holy light.

On the contrary, the fingers of his hands were moving rapidly.

Ling Ran was obviously simulating the process of suturing a severed finger. Compared with the Tang method suturing, the focus of suturing a broken finger has changed from tendons to blood vessels. The flexor tendons of the fingers are as thick as two or three rubber bands, and blood vessels are usually as thick as two or three rubber bands.

Within 0.5 mm, which is the thickness of the tip of a water pen, the difficulty of sewing is self-evident.

Small blood vessels can also cause blood clots.

Thrombosis is extremely dangerous and can be said to be a major factor in death and disability in the hospital. In order to prevent thrombosis, during the nursing process after suturing the broken finger, the nurse will constantly cut the wound to use heparin.

The prerequisite for using heparin is that the surgeon's needle insertion is stable.

Blood vessels that are only sutured but cannot be stably sutured are not so obvious in other parts of the body, but they are absolutely not allowed in replantation of severed fingers in hand surgery.

It can be said that stable suturing under the microscope is the biggest difficulty in replanting severed fingers. Yunyi Hand Surgery spent millions of dollars to build a practice room, which costs millions of dollars every year, just to train young doctors in suturing techniques.

In other departments, everyone operates directly on patients. Who would be willing to play with the tail of a white rat after get off work.

However, the hand surgery department does not do this, and the accident rate is so high that in recent years, hospitals have built their own practice rooms.

Lu Wenbin knew that Ling Ran had completed the graduation-level operations in the hand surgery practice room when he first started his internship, so he stared at Ling Ran's fingers closely, trying to see the key points of his operations.

The Hook Man can be done without any brain, but Lu Wenbin wants to learn it with his brain.

Watching and watching...

Watching and watching...

Lu Wenbin fell asleep quietly, with the sun shining on his cheeks, feeling refreshed and itchy.

"The patient is coming." Ling Ran's cell phone rang. It was Director Wang Haiyang's WeChat message.

Ling Ran opened his eyes suddenly, tore open the packaging of the chocolate, and ate each piece of chocolate in one bite.

After hurriedly heading to the operating floor and entering the operating room, Ling Ran saw Wang Haiyang with an ashen complexion.

"The operation is cancelled." Wang Haiyang gasped when he saw Ling Ran and said, "I was just going to send you a message. Go back and rest."

"What's wrong?"

Wang Haiyang hummed twice but said nothing.

The old nurse next to him was equally angry and said, "The patient's family members were so clever that they first used tobacco and incense ash to stop the bleeding on their palms, and then soaked the severed finger in ice cubes. As a result, the ice cubes melted and it was like soaking in water!"

Ling Ran was dumbfounded when he heard this. The incense ash only affects debridement. The nicotine contained in shredded tobacco will constrict blood vessels. Naturally, it is not a problem for small wounds. However, it is a big problem for replantation of severed fingers. As for soaking severed fingers in water, it will be even more problematic.

Allow secondary damage to the tissue.

"Can't meet the stitching standard?" Ling Ran was still a little unwilling.

Wang Haiyang said "grace" and said: "There is no need to sew it up, it's rotten."

The domestic index requirements for suturing broken fingers are very low. If this is not achieved, it can be said that it cannot be sutured.

Ling Ran said helplessly: "Don't the first responders in the ambulance understand?"

When Wang Haiyang wants to choose a disease, he can only choose from the ambulance in the emergency center to know the patient's condition.

Wang Haiyang pulled off the gloves he had put on and said: "The fingers were sent by the patient's family themselves. The patient's fingers were simply bandaged. The people in the ambulance recognized the incense ashes and didn't know there were tobacco shreds."

The equipment nurse also sat down and said: "The thief who works to death is perfect."

"Wait a minute, I'll find another one." Wang Haiyang felt a little embarrassed when facing Ling Ran. Everyone showed up as a team but disappeared. The captain had to stand up and say something.

Ling Ran could only pat his belly. He missed Boss Shao a little now.

If Boss Shao's finger was broken, he would definitely bring it to the hospital properly.

If I can't disinfect it, I'll do it myself.

Ling Ran sighed and said, "Then I'll go to the lounge and wait."

The operating room is very stressful, and he knows it very well.

Ling Ran sat in the operating room, opened the King of Glory, and after finishing three rounds, he saw another patient.

"The patient is 23 years old. He was chopped by the adulterer when he caught an adulterer. His index finger and middle finger were incompletely severed and contaminated by a large amount of food..." the roving nurse introduced while the three doctors were changing clothes.

Wang Haiyang listened to a piece of music: "This is good, not completely disconnected, and less difficult."

As he said that, he grabbed the patient's finger and looked at it, then frowned slightly and said: "The connected skin and flesh tissue have no blood vessels. After this debridement, it won't have much effect. It's better than nothing."

Ling Ran watched without saying a word.

He has performed hundreds of Tang operations, but he has no experience in replanting severed fingers.

Wang Haiyang stood on the operating table. After seeing the patient, his mood improved. He smiled at Ling Ran and said, "I will do the first operation first, and we will discuss the subsequent operations later, okay?"

"Okay." Ling Ran answered readily.

"Then let's get started. What is the general sequence for replanting a severed finger? First, debridement of the section, then bone set, then suture the tendons, then anastomose the nerves, then anastomose the blood vessels, and finally suture the skin... Ling Ran, you haven't done any bone set yet.

Right?" Wang Haiyang explained with a smile, like a senior doctor who likes to teach others.

"Yes, I didn't pick up the broken bones." Ling Ran was doing his job as a first aid, dutifully helping Wang Haiyang and chatting with him.

"Then let me talk more about it later when we are setting the bones." Wang Haiyang felt quite comfortable during the operation.

…

At the same time, Lu Wenbin ran wildly in the corridor, muttering: It's over, it's over, how could I fall asleep?
