Chapter 484

After doing all this, the operation has come to the most critical moment.

"Professor Chu, are you ready?"

"Yes!"

After looking at each other, the two began to remove the plaster fixed on the patient's leg.

The key reason why the emergency department did not rush to remove the plaster fixation was that the plaster had caused severe compression of the local tissue.

If the pressure is released rashly at this time, a large amount of necrotic tissue will enter the blood, and infection and hyperkalemia will instantly kill the patient.

This is also why the injured who were pressed under the house during the earthquake were conscious at first, but suddenly suffered cardiac arrest and coma at the moment of moving the heavy objects.

"Anesthesia, prepare adrenaline."

"Circulation, follow my previous operation and increase the dehydration volume of the blood filter to 500ml."

"Equipment, prepare to cut the bag and drainage device."

"Understood!"

Everyone said in unison.

After receiving Xiao Chenguang's instructions, everyone was ready, tense and waiting for the moment when the plaster fell off.

Then, with a hammer, the plaster instantly broke into pieces of tile-like white pieces.

Scattered on the ground.

This kind of plaster made of calcium carbonate and gauze is the most traditional material.

Chu Tianyu lifted the gauze hidden inside, and the patient's swollen legs came into view.

"How can it be compressed like this? Doesn't he feel any pain?"

This doubt once again surfaced in Chu Tianyu's mind.

After all, he performed the operation on this patient.

He knew the basic condition of the leg very well.

However, now.

The obviously swollen calf has obvious necrosis of some skin.

Even in the squeezed place, you can see the exposed blackened muscles.

If it weren't for the cold weather, such injuries would have started to fester long ago.

"I guess the patient didn't pay attention at first, and when he felt something was wrong, the nerves in this area were necrotic."

Xiao Chenguang said, but his hands were not slow.

He asked for a large bottle of iodine and started to disinfect the entire skin directly.

Then, hydrogen peroxide solution was used to sterilize the necrotic tissue for the second time.

Gurgle, gurgle...

When hydrogen peroxide came into contact with the patient's skin, the squeezed part began to sizzle and gas, and the transparent liquid instantly turned into a large amount of white foam.

It seemed to be swallowing up all the necrotic tissue around it.

"Director Xiao, the patient's blood pressure has begun to drop!"

As soon as the voice fell, the average blood pressure measured on the monitor was still 90mmHg in the previous minute.

The next minute, the cuff buzzed for a long time, and the blood pressure dropped to 60mmHg.

The sharp drop in blood pressure instantly caused a series of chain reactions.

In order to maintain the basic circulation, the heart, which had reduced ejection volume due to low blood pressure, could only beat desperately.

The heart rate instantly soared from 90 beats to 160 beats/minute.

A large number of atrial premature beats, ventricular premature beats, bigeminy, and trigeminy were displayed on the ECG monitor.

The alarm sounded continuously.

The volume was getting louder and louder.

It seemed to pierce everyone's eardrums.

The decrease in blood pressure, obstruction of systemic and pulmonary circulation, obstruction of blood oxygen exchange, and the patient's blood oxygen saturation had problems again.

Now, the operating room instantly became a rescue room.

The rescue medicine that had been prepared did not need Xiao Chenguang's reminder at all. The anesthesia had already pushed 20mg of dopamine into the patient's body.

Blood pressure began to rise.

"Have you used moxifloxacin hydrochloride?"

"Yes!"

"Okay." Xiao Chenguang nodded. This kind of blood pressure drop caused by infection is also called septic shock.

The use of ultra-broad-spectrum antibiotics is the key.

Moxifloxacin is used to fight infection, and later combined with meropenem + vancomycin to directly raise the antibiotic level to the highest level.

"Director Xiao, the skin is disinfected."

While rescuing here, Chu Tianyu was not idle either. He had already disinfected the patient's swollen skin.

"Okay."

Then the instrument nurse handed the installed scalpel to Xiao Chenguang's palm.

Without hesitation.

Along the necrotic skin, Xiao Chenguang raised his knife and fell, and a long incision of about 20cm fell on the patient's calf.

The metal retractor gently pulled left and right along the incision.

A 15X25cm wound surface came into view.

As the surrounding skin was decompressed, large bloody blisters appeared, one after another, and people who saw it had intensive phobia.

"The fascia layer and muscle layer on the inch side of the tibia and fibula are completely separated and necrotic, the nerves and blood vessels are damaged, there is no blood supply and touch..."

When Xiao Chenguang saw the wound, various diagnoses came out of his mouth.

"Leave a culture for the necrotic tissue, prepare for flushing and debridement, and perform closed negative pressure drainage."

Whether the leg can be saved and to what extent the function can be restored in the later stage all depends on the subsequent debridement and vascular nerve reconstruction technology.

Xiao Chenguang began to concentrate on the operation in the operating room.

Time passed by every second.

At the same time.

Chief Wu's special car had already left the provincial highway and started to drive towards the Provincial First Hospital.

"Why hasn't Xiao stepped down yet? The meeting is about to start."

Yang Dehuai, who arrived at the scene in advance, saw that the entire meeting room was full of people.

It was getting dark outside.

But Xiao Chenguang was still in the operating room, which made Yang Dehuai anxious.

Although he is the chairman of the Provincial Surgery Association, this is the Provincial First Hospital, not the Qilu Hospital where he works.

No matter how urgent it is, you can't just barge into someone else's operating room.

"Hey, I still have to make a phone call to ask."

Just when Yang Dehuai took out his mobile phone from his pocket and was about to call Xiao Chenguang to confirm how long it would take to finish the operation, a person appeared and surprised him.

"Xiao Guan? Why are you here?"

Outside the venue, a young man was walking towards him.

A closer look showed that it was Dr. Guan who was in the emergency room with them last night.

"I... have some questions for Chief Wu."

Dr. Guan hesitated for a moment and decided to tell the truth.

After all, Yang Dehuai also knew about the treatment plan in his hand.

Without Xiao Chenguang's approval, he found someone to verify the conclusion without authorization.

Such an approach is inevitably a bit shameful.

It would be better if he hadn't met Yang Dehuai. Now that he has met him, if he keeps hiding it and waits for someone to find out, Dr. Guan really doesn't know how to face Xiao Chenguang.

"You come to ask Chief Wu for advice?"

Yang Dehuai was stunned when he heard this.

Chief Wu is not someone that anyone can easily see. Since Dr. Suga dared to come, he must have something to rely on.

Yang Dehuai is an old and experienced man. Thinking of Chief Wu's expertise in the imperial capital and what happened last night, he understood it instantly.

"Are you going to ask Chief Wu about the plan for treating paraquat that Xiao Xiao gave me last night?"

"Yes."

Dr. Suga answered directly.

This surprised Yang Dehuai a little.

So he asked again.

"Is Chief Wu yours?"

"He is my teacher, or my master."

No one in Qilu Hospital knew about this relationship, but for today's research, Dr. Suga still said it.

"!!!"

Yang Dehuai was a little shocked.

He only knew that Dr. Suga had been to the imperial capital to study, but he didn't expect that the two had this relationship.

In this way, Yang Dehuai suddenly thought of a way to help Xiao Chenguang explain the reason for his absence from the meeting in front of Chief Wu.
