Chapter 751: with translation of chapter title

Huang Dazhi's doubt about the Shou Bing lies not in diagnosis but in technique.

As for this matter of technique, Zheng Ren can demonstrate it; the specifics of how to use it in the Shou Bing depend on each person's comprehension.

Even if Zheng Ren holds nothing back, most people still wouldn't understand.

After Professor Huang asked about the two relatively difficult Super-selective and Thrombectomy techniques, Xie Yiren finished the handover and walked out.

He understood the social cues, realized this wasn't a good time for chatting, and smilingly led Zheng Ren and the others to the Intervention Department.

Along the way, Professor Huang didn't say more, because Zheng Ren and Su Yun were about to fall asleep while walking. He just took care, making sure they didn't walk and fall asleep, getting hurt or bumped.

Upon entering the ward, Professor Huang came to the director's office door and said with a smile, "The director specially left the door for you, saying that if you need anything, you can come rest anytime."

"Thank you." Zheng Ren said vaguely.

Suddenly, hurried footsteps echoed in the hallway, and the sound of wheels scraping the floor grew loud.

Instinctively, Zheng Ren opened his eyes. In his daze, he thought he was at Haicheng Shi Yiyuan.

"What's wrong?" Zheng Ren asked in a dazed manner.

"Boss, it seems like a 120 Emergency rescue." Su Yun, also in a dazed state, saw nurses pushing a 120 Emergency medicine cart rushing to a ward and guessed as such.

"Let's go take a look." Zheng Ren also saw the situation clearly and immediately became a bit more alert.

Xie Yiren wanted to say something, but hesitated a moment, then still let Zheng Ren go.

She originally wanted to see where Zheng Ren was sleeping, then go drive around to see what she could buy to eat.

Unexpectedly, just after coming down, she encountered another emergency rescue in the ward.

Zheng Ren strode into the ward and saw a patient whose hands and feet twitched slightly, wanting to flail about but unable to. He muttered something indistinctly, not clear.

Nurses, doctors, and volunteers acting as aides were rescuing at the bedside; the person couldn't be seen, and the System Panel temporarily gave no diagnosis.

"Boss, this person is probably a programmer; his sleep-talk is all code, really dedicated." Su Yun said softly.

"Programmer?"

"From his delirious talk, it should be like that." Su Yun said.

"Isn't this a post-operative patient? What happened?" Professor Huang was somewhat surprised and hurriedly asked.

"Teacher Huang, after the stent procedure the patient received a blood transfusion and blood pressure reduction, then developed symptoms such as motor incoordination and blurred vision, followed by delirium, dizziness, headache, accompanied by nausea and vomiting, the vomitus being gastric contents." The doctor reported.

"Stent?" Zheng Ren was stunned for a moment.

Nowadays, the patients are basically those with hemorrhagic shock; a blood transfusion suffices, and generally there is no blood pressure reduction.

Adding the stent, Zheng Ren immediately thought of the abdominal aortic dissection patient he had diagnosed when he first arrived.

That patient had undergone a stent, and Zheng Ren was certain the stent procedure would pose no problem; his own Shou Bing experience and the completion degree given by Big Pig Trotter could corroborate that.

What's going on?

He stepped forward, and while the volunteer went to fetch something, he saw the patient.

The diagnosis shown in the upper right of his vision by the System Panel was—post-interventional embolization for pelvic fracture, post-stent for abdominal aortic dissection aneurysm, and thiocyanate poisoning.

Already dazed from fatigue, Zheng Ren misread the diagnosis.

His first reaction was cyanide poisoning!

This damn is a big deal; could someone have poisoned him?

Zheng Ren was startled awake, his whole body jolted.

He then clearly saw it was thiocyanate poisoning, quickly recalled it in his mind, and his expression twitched slightly.

Seeing Zheng Ren's condition was off, Su Yun squeezed over and asked, "What's wrong, Boss?"

"It's fine." Zheng Ren shook his head, but he couldn't tell Su Yun about the cyanide poisoning; if he did, this guy would blab about it until next year.

"Is this the post-operative patient of the abdominal aortic dissection aneurysm that I performed?" Zheng Ren asked.

"Teacher Zheng, yes." Professor Huang felt the senior doctor's strong aura and instinctively addressed him as Teacher.

"What blood pressure reducer are you using?" Zheng Ren asked.

After stenting for an aortic dissection aneurysm, blood pressure also needs to be kept stable until the peritoneal patch fully seals the breach; usually one or two days of antihypertensive drugs are given, then it can be stopped. There's nothing special about it—it's standard treatment.

"Sodium nitroprusside, administered via micro-infusion pump at a dose of 8 mg/kg/min." The junior doctor immediately reported the dosage.

Zheng Ren then understood what had happened.

He said in a deep voice: "Stop the sodium nitroprusside, immediately contact nephrology, and go for dialysis right away."

Professor Huang was stunned—what kind of maneuver is this? Acute renal failure? Normally, renal failure shows up in urine output, but this patient's urine output is normal.

Although hemorrhagic shock causes low urine, it hasn't yet reached the level of less than 50 ml per hour indicative of renal failure.

He had doubts, but upon hearing Zheng Ren's words, he immediately instinctively stopped the micro-infusion pump delivering sodium nitroprusside.

"No need for excessive measures; just be careful not to let the vomitus be aspirated, which could cause asphyxiation." Zheng Ren said.

"……" Professor Huang puzzled, he had the junior doctor immediately contact nephrology and come to Zheng Ren's side, asking, "Teacher Zheng, is this acute renal failure?"

"More or less." Zheng Ren replied.

Sweat……profuse sweat……

"More or less," what kind of answer is that?

Professor Huang for the first time felt Zheng Ren was somewhat unreliable, but this thought was nipped in the bud as soon as it arose.

The other party, being a Nobel Prize Nominee, his identity alone could prove many things.

Besides that, having personally witnessed the Shou Bing, it was absolutely the most impressive one he'd ever seen; doctors of this sort usually have very rich clinical experience.

His own doubts ultimately only proved that his clinical experience was lacking and his diagnosis was wrong.

Professor Huang looked at Zheng Ren with an inquiring gaze, waiting for his explanation.

"It's thiocyanate poisoning." Zheng Ren said.

Uh…… Clinically, using sodium nitroprusside is commonplace; many patients with high blood pressure need it for control. Over the years, Professor Huang has rarely heard the diagnosis of thiocyanate poisoning.

Not just rare, but basically nonexistent.

Thiocyanate poisoning, he sounds so unfamiliar.

"It's probably a problem with sodium nitroprusside metabolism." Su Yun immediately thought of some possibilities and asked.

"Mm." Zheng Ren said, "Sodium nitroprusside is a nitro-hydrocyanate salt, directly acting as a potent vasodilator on the arterial and venous Blood Vessel bed."

Sodium nitroprusside is continuously pumped in, first, via red blood cells Transformation into cyanide, then, via hepatic thiocyanate enzyme Transformation into the final metabolite thiocyanate.

Thiocyanate is excreted by the kidney, the half-life of those with normal kidney Function is 4~7 days. Patients with kidney Function failure have accumulation. If the dose is too high, high blood levels of the metabolite thiocyanate salt easily cause poisoning.

"But the patient has no abnormal kidney Function." Professor Huang struggled to recall the patient's lab report, said.

"Before there wasn't, now there is."
