"Didi..."

Outside the operating room No. 3 of Gusu City, Jiao Kaifu's wife was paced back and forth anxiously. It has been more than two hours since his husband was sent into the operating room.

The more she waited, the more she felt distressed, for fear that she would hear bad news in a while.

Jiao Kaifu is the only family pillar in their family. He relies on him to make money by himself. Once the operation is not successful, the family will lose this family pillar, and the consequences will be unimaginable.

At this time, the operation was going well in the operating room.

"The ventilator works fine and the anesthesia remains normal."

"The patient's physical indicators are very stable."

Kong Shuo wiped his sweat and threw the last piece of tissue around the tumor into a stainless steel basin next to it.

"Okay, it's finally clean."

The originally clean stainless steel basin is now filled with various blood-red and blood-red skin tissues and a large red and black "cauliflower". It looks very disgusting and is constantly emitting a foul smell.

Kong Shuo cut a gap of 10cm in diameter on Jiao Kaifu's abdominal wall, and the abdominal wall of nearly half of the abdomen, including the skin, was cut off.

The abdominal wall reconstruction surgery that he will perform next is not difficult at all. Fortunately, Dr. Zhang Han, whom he invited, is also a highly skilled plastic surgeon.

Kong Shuo smiled relaxedly, put down the scalpel and gave up the main surgery position. He took off his mask and said to Zhang Han: "Director Zhang, I'll leave it to you next."

Zhang Han nodded, stood in the main surgery position, lowered the operating table to a height that was comparable to her height, and began to perform flap transplantation for Jiao Kaifu.

Because the abdominal defect has a large hole, the transplanted flap can only be selected from the skin on the thigh or back. After discussing with Jiao Kaifu in advance, Zhang Han chose to take a muscle flap from the thigh to move it to the position of the defect. Because the thigh flap is easier to remove, the back needs to be turned over, which is difficult to do.

After getting ready, Zhang Han carefully began to take the flap.

Two hours have passed since the operation was performed, and the next skin graft will take one or two hours of surgery.

This operation is undoubtedly a major operation, at least the time of the operation is indeed similar to that of a major operation.

The reason why Ruikang Medical wants to find patients with this major surgery to conduct clinical trials is that among the patients who undergo the surgery, only those who require general anesthesia and have a long surgery time, they need to use an invasive ventilator to establish an artificial airway for mechanical ventilation.

Generally, when positive pressure ventilation is implemented in a short period of time, you only need to use a mask to connect to the ventilator and use a normal non-invasive breathing mode.

However, if the positive pressure ventilation time is longer, an artificial airway must be established, which is irreplaceable by a mask!

There are two reasons!

On the one hand, the mask tightly covers the patient's face and nose, making the patient very uncomfortable and easily causes local skin inflammation and necrosis.

On the other hand, the pressure inside the mask is much higher than the open pressure of the esophageal cardiac sphincter, causing a large amount of gas to enter the esophagus and stomach, causing abdominal distension, nausea, vomiting, and even intestinal obstruction.

These are all disadvantages of using masks to provide oxygen for a long time.

So in fact, it is actually incorrect to see vegetatives or patients lying in bed and wearing masks for a long time to provide oxygen.

Generally, long-term positive pressure ventilation, such as in the intensive care unit, patients who are unconscious for a long time, and patients with various respiratory and acute lung diseases, all can be intubated to establish artificial airways and mechanical ventilation is performed using an invasive ventilator.

Because when the patient is in a coma or anesthesia, the normal physiological reflex is inhibited, resulting in damage to the airway protection mechanism, prone to aspiration and secretions retention in the body, which may lead to severe lung infection.

Therefore, for patients with damaged airway protective mechanisms, it is necessary to establish an artificial airway to prevent aspiration and secretion retention.

Jiao Kaifu's hand requires general anesthesia, and the time difference between the surgery is not short, which takes at least four hours. Naturally, it is necessary to establish an artificial airway and use an invasive ventilator to provide oxygen. He is a patient who is very suitable for participating in Ruikang's clinical surgical trials.

Ruikang Medical did not disappoint Jiao Kaifu's trust. The ventilator did not fail any problems during the entire operation and ran very smoothly.

Although the operation was complicated, everything went smoothly.

Until Zhang Han rebuilt Jiao Kaifu's messy abdominal wall, implanted a musculous flap, and sutured the gap, the operation was over.

After bandaging Jiao Kaifu's thigh that was missing with gauze and medicine, the battle was perfectly successful.

Zhang Han and Kong Shuo checked the suture of the wound together and confirmed that there was no problem, he said to the anesthesiologist: "Okay, the operation is very smooth and you can push it to the awakening room."

Ersuke walked out of the main entrance of the operating room and informed Jiao Kaifu's family of the operation that everything went smoothly.

The anesthesiologist directed the circuit nurse to carry a ventilator and pushed Jiao Kaifu into the recovery room of the surgical layer.

Although the operation has been completed, the ventilator is still running with all his responsibility, and the ventilator task has not been completed yet.

After Jiao Kaifu advanced to the wakefulness room, several Ruikang testers paused on the screen of the ventilator. The high flow of pure oxygen quickly rinsed into Jiao Kaifu's breathing circuit and washed away the remaining anesthetics.

Soon, the concentration of inhaled anesthetic inhalation in Jiao Kaifu's alveoli decreased.

You should know that the cleaner the inhaled anesthetic, the more conducive it is to smooth the awakening process and the recovery of the patient. Too much residual may not only cause the patient to be irritable, vomit, or even inhibit the awakening and breathing.

And it is already the lowest concentration that can be reduced to, which shows that Ruikang's ventilator performance is very good.

After about twenty minutes, Jiao Kaifu, who was lying on the bed, gradually regained consciousness. The tester immediately pulled down the artificial trachea inserted into his mouth. Jiao Kaifu coughed a few times, staring at the ceiling in a daze, and his reaction was a little slow.

The anesthesiologist reached out and waved Jiao Kaifu's face, and asked, "Are you awake? How do you feel now?"

Jiao Kaifu was stunned for a while before his eyes focused, and he said blankly: "I feel nauseous and want to vomit. Doctor, have I succeeded in the operation?"

The anesthesiologist reached out and took out a pen from the pocket of the white coat's chest. While recording the information on the anesthesia list, he explained lightly: "It is normal for anesthesia to feel nauseous and vomiting just after waking up. It will be cured for a few hours. Don't worry, your operation is very successful. The tumor tissue that was cut has been sent for pathological analysis. Director Kong did a good job in the operation, and the resection was very clean and there were no residues."

"The chance of recurrence will be much smaller next."
