In the first week, Tanglou started practicing his dressing-changing technique.

The purpose of dressing change is to prevent surgical infections, that is, infectious diseases and trauma that require surgical treatment, as well as complications after surgery.

Tang Lou was in the dressing room, washing his hands, putting on a mask and hat, and the regular dressing materials that Xu Lanlan had prepared for him early:

Sterile cotton swabs, sterile saline, 3% hydrogen peroxide, 0.5% iodophor, erythromycin eye ointment, sterile dressings, breathable tape, etc.

The patient who needed dressing change was a patient who had experienced an explosion in a chemical plant. The wound on his right leg had some suppuration.

Tanglou adjusts the patient's posture to a suitable position, not only to ensure the patient's comfort, but also to make it easier for him to change the dressing.

The patient's leg was previously burned by fire. Although the wound was debrided, after a few days, the tissue in the center of the wound was still necrotic and liquefied. The yellow pus was filled with a large number of pathogenic bacteria and neutral cells, and was surrounded by a complete cavity wall.

, which is commonly known as an abscess.

Based on previous classroom experience, Tanglou disinfected the patient's skin and performed local infiltration anesthesia.

After that, it was cut layer by layer. Since the technique had not yet been exchanged, Tanglou's movements were naturally a bit jerky. As for the way to wield the knife, he chose the bow-holding posture.

The bow-holding position is one of the surgical knife-holding methods. The bow-holding position is the most commonly used, that is, the thumb is under the knife handle, the index finger and middle finger are on the knife handle, and the wrist is used to exert force.

It is often used for longer skin incisions, and is obviously very suitable for patients with large abscesses at this time.

After concentrating on making several incisions, Tang Lou cut through the patient's deep fascia. The sharp tip of the knife entered the thick cavity before Tang Lou exerted force.

Yellow juice overflowed from the incision, thick like snot, and mixed with some blood.

Tang Lou put down the blade and squeezed it gently with his hands wearing translucent thin gloves, as if squeezing a pimple that was enlarged ten times.

The blood-yellow liquid continued to flow out, until only bright red blood remained. The Tanglou stopped draining the blood and cleaned it up.

Tanglou once again held the knife, this time using the pen-holding style, which is the way to hold the pen. The movement is mainly in the fingertips. This method is used for short-distance and fine operations.

It is also the method that Tanglou is most familiar with. Before using this method in the laboratory, he often dissected the blood vessels and nerves of mice.

Of course, this was the first time it was used on the human body. Tanglou was extremely cautious and cut off the patient's necrotic tissue bit by bit.

After a full five minutes, Tanglou removed all the necrotic tissue.

After carefully admiring the clean wound, Tang Lou began to apply dressing on the wound carefully.

After completion, use white gauze to wrap around the patient's wound and compress it.

Naturally, the bandaging was not completed yet. Tanglou checked again to make sure that the wound was not leaking...

It took about half an hour for Tanglou to complete the dressing change on the first patient.

After completing a dressing change in the tenement building, Xu Lanlan quickly arranged for the second patient to come over and at the same time cleaned up the mess left by the tenement building.

"Dr. Xiao Tang, the patients you need for dressing change have been screened for you, and four have been arranged for you this morning."

Tanglou went to the side to continue disinfection and preparations before dressing change, while giving instructions:

"Okay, oh, by the way, the last one in the morning, arrange a suture case for me."

Xu Lanlan was a little confused. She looked at the Tanglou and persuaded:

"Dr. Xiao Tang, no one knows that your suturing skills are already good enough. Director Shen also said that there is no need to practice suturing. This week, you only need to change the dressing."

Naturally, Tanglou couldn't explain it. He had a suturing line, and he could regain his energy by suturing just one patient, so he had no choice but to bite the bullet and said modestly: "It takes practice to change dressings, but you can't lose sutures. If you don't practice more, I'll just do it every day."

The last one at noon, and one in the afternoon, keep it cool."

After listening to Tang Lou's words, Xu Lanlan looked at Tang Lou with admiration and nodded: "As expected of Dr. Xiao Tang, no wonder the sutures are so good. He is so diligent."

The second patient's wound was on the abdomen, and the dressing had just been changed yesterday. It may be that the previous intern's operation technique was not good, the pus was not drained, or the disinfection was not careful.

The superficial dressing has been soaked with purulent exudate and needs to be replaced.

Tang Lou carefully pulled out the Vaseline oil gauze strip, and used hydrogen peroxide cotton balls, 0.1% chlorhexidine solution cotton balls and 0.9% normal saline to rinse the wound repeatedly.

Since there is no anesthesia, the patient will naturally grimace in pain during the dressing change. However, since Tanglou is equipped with a one-star dressing change technique, overall the technique is relatively professional.

Tang Lou controlled his strength. In order to stimulate the growth of granulation tissue, Tang Lou picked up the dressing tweezers and gently scratched the wound edge until a small amount of blood flowed out. He then used saline gauze to drain the wound to promote the fresh granulation from the wound.

The wound base is gradually healed from deep to shallow.

After doing all this carefully, Tang Lou adjusted his standing posture and turned his neck slightly.

"Dr. Tang, thank you for your hard work."

The patient lay flat on the bed, looked at the tenement building, said with some gratitude and some embarrassment.

"It's okay, it will be over soon. Generally speaking, your wound is healing well. After I change your dressing today, it will heal faster."

Since he has inspired a master of surgery, Tanglou naturally talks to patients with confidence.

"Really? But, Doctor Tang, your technique is much better than that of the little doctor yesterday, and the pain is much less."

The patient was hesitant about Tanglou's claim of rapid healing, but he could still feel the lighter pain intuitively.

After treating the inside, Tanglou will cover the outside with clean and disinfected dressings.

"I will change your dressing once a day from now on. It will take about 5 days to heal."

Tanglou said with confidence.

"Really? That's great."

Although the patient was lying down and unable to get up, he still gently tapped his chin. Yesterday, Dr. Leng was indeed unreliable. He also said that it would take at least 7 days to heal.

While Tanglou was working hard to change the dressing, outside the dressing room, through the large glass, Huo Tong nodded with satisfaction. Tanglou's serious efforts made him very satisfied, and he took out his mobile phone:
