Chapter 1852: and ===GLOSSARY===

"Moreover, what you said is wrong." Zheng Ren said: "BradleyA. Gross et al. conducted a systematic review and synthesis of the literature on current vascular interventional treatment of smog disease and smog syndrome, and the study was published in NeurosurgRev."

"He only summarized 28 patients who underwent vascular interventional treatment, of whom 11 had intravascular stents and 17 had angioplasty. Only 7 of the surgeries were successful."

"Twenty-five percent." Su Yun said.

"First, Doctor BradleyA. Gross is biased toward interventional surgery, and this is beyond doubt. In the conclusion of his article, he said the results clearly do not support using vascular interventional treatment for smog disease and smog syndrome, and they will need to conduct more research and gather more data to prove this point in the future."

Su Yun pursed her lips, glanced at her phone, and the taxi was already very close.

"I believe that any research work, if it cannot maintain an objective and fair attitude, its conclusion is worth doubting." Zheng Ren said.

"No matter what you say, regarding interventional surgical treatment for smog disease… I'll ask Sanbo or Tiantan to see if they've carried it out. I'm thinking, I don't know many people in neurosurgery; is there anyone who knows the neurosurgery department at Huashan?"

Su Yun chattered on as a car with its hazard lights flashing pulled up.

After getting in the car, Su Yun held her phone and coordinated matters, while Zheng Ren thought about the connection between smog disease and coronary artery surgery.

If surgery were performed in the emergency department, what risks would it face? This goes without saying.

But Zheng Ren was not afraid.

First make preparations; then, after seeing the patient, go to the System Operating Room to perform the surgery to verify his viewpoint.

Although there was still some surgical training time left, Zheng Ren habitually did not want to "waste" it.

Over the past two days, he had already twice used his surgical training time to think about the condition.

One time was due to eating animal thyroid causing hyperthyroidism and thyroid storm; the other time was a complete waste because he peeled garlic himself.

He blamed this on Chang Yue, Zheng Ren thought to himself.

They soon arrived at 912; the distance was not far, and they could have gotten there by running, but Su Yun habitually called a car, which didn't matter.

Zhao Yunlong was in the EICU, and the two did not hesitate, going straight to the EICU.

The EICU in Building 912 is a U-shaped structure; each patient is individually isolated, and there are makeshift small tables in the hallway where medical staff can casually lean over and nap when fatigued.

Medical staff basically have no time to go to the Zhibanshi to rest; the EICU is such a peculiar existence.

It was already nearly ten o'clock at night; after entering the EICU, the first thing that caught their eye was the busy workstation.

Four on-call trainees, including the one who worked the night shift last night, were still busy. After 40 consecutive hours without rest, that trainee doctor showed no sign of fatigue, the whole person sunk into a pathological state of overexcitement.

Zheng Ren shook his head. If the Emergency Department is unpopular, then ICU and EICU, these critical care units, are certainly even less popular.

Haicheng Shi Yiyuan's ICU is still okay to say, that side has relatively few critical emergencies. But the EICU of 912 is another world entirely, its 40 beds always running at full capacity.

If it weren't for trainee doctors, the operation of 912 would directly face collapse.

Not only this side, including Zheng Ren's Community Hospital, it's the same. Now the Community Hospital has enough nursing staff, but doctors are basically trainee doctors.

Zheng Ren had no time to lament these things; he quickly followed Su Yun into an isolation room.

Zhao Yunlong stood sternly by the bedside, staring intently at the patient's ECG monitor.

"Lao Zhao, what's the situation?" Su Yun asked.

"After surgery, there have already been 3 episodes of rapid ventricular arrhythmia, corrected by defibrillation. The situation is not optimistic, come take a look." Zhao Yunlong didn't turn his head, merely speaking in a gruff voice.

"Tell me from the beginning." Zheng Ren said.

Zhao Yunlong turned his head, seeing Zheng Ren also follow in, then he turned around: "Chief Zheng, you're here too."

"Stop calling Chief Zheng Chief Zheng, call him Boss." Su Yun said while squatting down to look at the two side chest bottles.

The drainage output is not large; the Shou Bing should be fine. It's probably due to the patient's own condition, causing rapid ventricular arrhythmia after the bypass surgery.

"The patient had occult onset before surgery." Zhao Yunlong ignored Su Yun's nagging, seeming already accustomed, and directly reported the condition.

Zheng Ren's eyebrows furrowed instantly.

"Occult onset?" This…… Zheng Ren found it interesting.

So-called occult onset means the patient has no symptoms at all, but by chance the condition is found to be serious and requires treatment.

Putting it broadly, all early-stage tumors could be considered occult onset. However, saying so is not accurate, as early-stage tumor onset is not serious.

What's truly troublesome is when the condition is extremely severe but the body shows no reaction, at least the patient themselves doesn't notice the symptoms.

Such situations are rare; I didn't expect to encounter one today.

The patient had a myocardial infarction, yet still had occult onset…… Zheng Ren this time had eighty percent confidence that the patient's cerebral Smog Disease might be a key factor, causing the patient not to feel precordial pain.

Of course, this is just a speculation.

"The patient experienced chest tightness and shortness of breath for three months, worsened over the past three days and came to our hospital's Respiratory Department. Chest CT showed severe aortic calcification and cardiomegaly, so they were admitted to the Cardiology Department. Coronary angiography revealed disease in three vessels: the left anterior descending artery was 90% blocked, the right coronary artery 95% blocked, and the circumflex artery 95% blocked."

Such severe Coronary Heart Disease, Zheng Ren could already guess what the patient had gone through.

Sure enough, Zhao Yunlong later confirmed Zheng Ren's speculation.

"During the stay in the Cardiology Department, the patient's family refused cardiac interventional surgery treatment. After the angiography, while the family was still discussing, the patient suddenly fell ill, rapid ventricular arrhythmia followed by cardiac arrest." Zhao Yunlong said: "Emergency CPR, proceed with cardiac stent procedure."

Zheng Ren envisioned in his mind the kind of Emergency Rescue conducted this afternoon by Cardiology and Cardiothoracic Surgery that causes excessive hormone secretion.

Cardiac arrest, a round of compressions, while being sent to the catheterization lab.

This process sounds simple when described; I estimate the doctors in the Cardiology Department haven't yet recovered from it.

"During the stent placement, the patient suddenly had two episodes of rapid ventricular arrhythmia." Zhao Yunlong said: "After balloon dilation, any stimulation stops the heart. Later we could only perform emergency thoracotomy and coronary artery bypass graft surgery."

This is roughly what Zheng Ren thought; basically it's this process.

"Post-op, drainage from both sides' chest tubes is not much, pericardial drainage is also not much, but rapid ventricular arrhythmia occurs frequently, already defibrillated three times." Zhao Yunlong said: "We're preparing to do IABP, but the patient's family hasn't responded yet."

IABP, also called intra-aortic balloon pump, is one of the mechanical circulatory support methods; through physical action, it raises aortic diastolic pressure, increases coronary blood flow, and improves myocardial function.
