Zhang Yan put on sterile clothing, put on gloves, and walked into the operating room.

The patient is a middle-aged man in his thirties, who is already lying on the operating table.

"Doctor, thank you for your trouble!" the patient said to Zhang Yan very politely.

"It's okay. This is just a minor surgery. You will be active again within ten and a half days after the operation." Zhang Yan said with a smile.

"Dr. Zhang, how do you perform anesthesia?" The anesthesiologist was the same one who performed Zhang Yan's severed finger replantation surgery last time.

"Local anesthesia in the abdominal cavity will do." Zhang Yan nodded to the anesthesiologist and said.

"OK!"

The anesthesiologist soon completed the local anesthesia. After the examination, he reported to Zhang Yan that the operation could be performed.

Zhang Yan adjusted the patient's position.

He looked up and saw Liang Yan standing there helpless, covering her eyes with both hands.

"In the eyes of doctors, there is no gender. When you put on this white coat, you only see patients, not men or women.

If you care about the difference between men and women, then don't wear this outfit." Zhang Yan said to Liang Yan in a deep voice.

He could understand that after all, Liang Yan had never received professional medical training. It was the first time she entered the operating room and saw such a scene, so she was naturally a little uncomfortable.

For appendicitis surgery, the lower part needs to be exposed.

Especially for this traditional appendicectomy, a larger area needs to be exposed.

It can be said that everything that should be exposed has been exposed. Liang Yan, an unmarried girl, did not run out screaming, which can be considered to be calm.

"Keep an eye on her. If she feels any discomfort, take her out as soon as possible." Zhang Yan whispered to the head nurse.

Zhang Yan worried for a while that when he opened the patient's stomach, Liang Yan would vomit.

After adjusting the body position, Zhang Yan spread the surgical cloth (sterile drape) to expose the surgical site.

"Start the operation!" Zhang Yan shouted.

It not only reminds the visiting nurses to time the clock, but also reminds everyone to pay attention.

Zhang Yan took the electrocoagulation scalpel handed over by the instrument nurse and gently cut open the subcutaneous tissue.

In this era, electrocoagulation scalpels were still used, which were the first generation of electronic scalpels.

The electrocoagulation scalpel is definitely a great progress in the history of scalpel development.

As expected of a hospital in the capital, a district-level hospital has an advanced electrocoagulation scalpel. You must know that most hospitals in the country are still using stainless steel scalpels for laparotomy.

Traditional stainless steel scalpels will not be eliminated, but electronic scalpels are more convenient and doctors do not need to worry about bleeding capillaries.

The electrocoagulation scalpel can instantly coagulate capillaries through the high temperature of electric current and reduce capillary bleeding.

"This..." Looking at the diameter of Zhang Yan's incision, Peng Dahai was stunned for a moment, opened his mouth, but ultimately remained silent.

Zhang Yan is the chief surgeon, he is just an assistant. It is taboo to question the chief surgeon's operation on the operating table.

The incision made by Zhang Yan was only four centimeters long. You must know that when they usually perform appendicectomy, the incision is ten centimeters long.

“In appendicitis resection, a larger incision is not better; a larger incision is not conducive to postoperative recovery.

We just need to ensure that there is enough vision and operating space during the operation." Seeing Peng Dahai's confusion, Zhang Yan explained with a smile.

"bite!

The host teaches junior doctors during surgery, triggering the halo of preaching, teaching, and resolving doubts.

The understanding of lower-level doctors increases.

The host can obtain feedback rewards based on the learning status of subordinate doctors.

Including but not limited to experience rewards and physical rewards.”

Zhang Yan felt happy, if this is the case, then I will have to say a few more words.

"The surgical field of view and operating space can be obtained by adjusting the body position." Zhang Yan explained patiently.

While talking, the peritoneum had been opened and the appendix was exposed.

"Come and take a look!" In order to verify his statement, Zhang Yan deliberately gave up the surgical position to let Peng Dahai feel the importance of posture more intuitively.

"Here, Dr. Zhang, from your position, the surgical field of view is very clear!" Peng Dahai said in surprise.

What surprised Peng Dahai even more was that with Zhang Yan's explanation, some previously confusing knowledge points suddenly became clear.

His mind seemed to clear up a lot all of a sudden. He could understand what Zhang Yan said and had his own experience.

"This is the importance of posture. When we perform surgery, we cannot just do it with our heads down, we must think more.

As the old saying goes, it is better to believe in books than to have no books at all. We doctors are a profession that constantly challenges tradition.

If you don't have the heart to challenge authority and tradition, you will never become a great doctor.

Especially us surgeons, when encountering something, we should ask more why? Think more about why we are doing this and what are the benefits of doing it? Is it okay if I don’t do it?

You have to have a skeptical heart." Zhang Yan took the opportunity to instill his medical philosophy in everyone.

"You three should also come and take a look!" Zhang Yan said to Zhao Shengli, Qian Hongying and Liang Yan.

Anyway, one sheep is being driven, and a group of sheep is being herded.

When it comes to teaching, Zhang Yan definitely believes that the more the better.

The patient's appendicitis only had an abscess and no perforation, so there was no need to worry about complications such as peritoneal infection, and Zhang Yan became more relaxed.

I took the opportunity to come here and teach surgery.

This is something that is good for you and me.

"Making an oblique incision from the middle and outer 1/3 of the line connecting the anterior superior iliac spine can make our surgical field clearer."

After all four people had looked at it, Zhang Yancai returned to the operating position and continued to complete the operation.

"gauze!"

Zhang Yan took the gauze pad and pushed the small intestine inward, first found the cecum, and then followed the three colon belts to the top of the cecum to find the appendix.

"Tissue forceps!"

"Vascular forceps!"

Zhang Yan took the tissue forceps and blood vessel forceps, reached into the knife edge, and gently lifted out the appendix.

"The appendix usually exists at the top of the cecum, but there are also a few appendices that exist behind the cecum. Don't worry if you can't find the cecum at the first time, take your time.

As long as you haven't had an appendectomy, you can definitely find it."

While Zhang Yan was explaining, he quickly cut out the appendix, then ligated the appendiceal artery and sutured the appendix stump.

After carefully examining the abdominal omentum and confirming that there were no infection complications, the appendix was returned to the abdominal cavity and the small intestine returned to its original position.

After checking again, Zhang Yan raised his head and said to Peng Dahai: "Close your abdomen."

"Okay!" Peng Dahai happily agreed.

He likes to do abdominal intubation the most. He used to do the abdominal intubation for the teacher, but now the teacher doesn't let him play with it. Fortunately, there is Dr. Zhang.

He can continue to do his job.

"I don't know how you did it in the past, and I don't care. In the future, before my abdomen is closed for surgery, I must inventory the surgical equipment, including how many pieces of gauze were used in the surgery.

Every piece of gauze must be of the correct size, and the instrument nurse confirms that there is no problem before you can close his abdomen." Just as Peng Dahai was about to close his abdomen, Zhang Yan took the vascular forceps and knocked directly on his wrist, very seriously

said.

"I understand, Doctor Zhang!" Peng Dahai was a little at a loss when Zhang Yan stared at him, so he quickly agreed.

Turn to see the equipment nurse.

The instrument nurse also hurriedly counted the surgical instruments and gauze in a panic.

"Bring a few pieces of gauze from the equipment room. I used a few pieces during the operation. The remaining pieces must be appropriately numbered." Zhang Yan gently explained to the equipment nurse.

"I know Dr. Zhang."

After checking and confirming that there were no problems, the instrument nurse looked up at Zhang Yan and said, "Dr. Zhang, there is nothing wrong with the instruments and the gauze is of the correct size."

"Yeah! After the inventory, you have to tell the doctor responsible for abdominal closure. After getting your information, the doctor can perform abdominal closure." Zhang Yang nodded to the instrument nurse.

Peng Dahai took a deep breath and began to close his abdomen.

Zhang Yan watched Peng Dahai finish closing his abdomen, then gave the patient instructions before turning and leaving the operating room.

"bite!

Through the host's patient explanation, junior doctor Peng Dahai successfully understood the resection of appendix with abscess and advanced to the proficiency level.

Reward the host: Appendectomy is upgraded to master level, 1000 experience, 100 yuan in cash, and 5 catties of food stamps.

Through the host's patient explanation, junior doctors Zhao Shengli, Qian Hongying, and Liang Yan initially understood the entry-level approach to appendectomy.

Reward host: 300 experience, 50 yuan in cash, and 2 catties of food stamps.”

Hearing the system prompts, Zhang Yan was delighted. As expected, teaching was not just about performing surgery, but the rewards were richer.
