The Surgeon’s Studio

thiocyanate poisoning.
His mind quickly recalled what it was and his expression changed slightly.

Su Yun saw that Zheng Ren’s condition was not right, so he squeezed forward and asked, “What’s wrong, Boss?”

“Nothing.” Zheng Ren shook his head.
He could not tell Su Yun about cyanide poisoning.
If he did, this fellow would simply talk about it until the next year.

“It’s a postoperative patient of the abdominal aortic dissection aneurysm that I did, right?” Zheng Ren asked.

“Yes, Teacher Zheng.
“Professor Huang felt the powerful aura of a senior doctor, so he subconsciously called him teacher.

“What was done to lower the blood pressure?” Zheng Ren asked.

Even after the operation on an aortic dissecting aneurysm, one had to maintain stable blood pressure.
It would be fine once the rupture was completely blocked by the peritoneal shelf.
Normally, one had to give blood pressure medicine for one to two days before it could be stopped.
There was nothing special about it.
It was all routine treatment.

“Sodium nitroprusside, micro-pump it in.
The dosage is 8 μg/kg/min.” The junior doctor immediately reported the dosage.

Zheng Ren then knew what had happened.

He said in a deep voice, “Stop the sodium nitroprusside.
Contact the nephrology department immediately and go for dialysis.”

Professor Huang was stunned.
What was this operation? Acute renal insufficiency? Under normal circumstances, the performance of renal insufficiency was on the urine volume and this patient’s urine volume was normal.

Although the urine volume was low due to hemorrhagic shock, it was not below the level of 50ml per hour for renal insufficiency.

He had his doubts but when he heard Zheng Ren’s words, he immediately stopped the micro-pump and started pumping sodium nitroprusside.

“There’s no need to give too much treatment.
Just be careful not to accidentally aspirate the vomit and suffocate the patient,” Zheng Ren said.

Professor Huang was puzzled.
He arranged for the junior doctor to immediately contact the nephrology department.
He came to Zheng Ren’s side and asked, “Professor Zheng, is it acute kidney failure?”

“Sort of,” Zheng Ren replied.

He was sweating… What sort of answer was that?

For the first time, Professor Huang felt that Zheng Ren was a little unreliable.
However, this kind of thought was nipped in the bud as soon as it appeared.

Zheng Ren was a candidate for the Nobel Prize.
His identity alone could solve many problems.

That was not all.
He had personally witnessed the surgery.
He was definitely the most awesome doctor he had ever seen.
Usually, doctors like him had a lot of clinical experience.

His own suspicions could only prove that he had little clinical experience and his diagnosis was wrong.

Professor Huang looked at Zheng Ren with an inquiring gaze and waited for his explanation.

“It’s thiocyanate poisoning,” Zheng Ren said.

Uh… It was common practice to use sodium nitroprusside in the clinic.
Many patients had high blood pressure and needed to use sodium nitroprusside to control it.
For so many years, Professor Huang had rarely heard of the diagnosis of thiocyanate poisoning.

It was not rare, but cases were almost nil.

Thiocyanate poisoning sounded so strange to him.

“It’s the metabolism of sodium nitroprusside, right?” Su Yun immediately thought of some possibilities and asked.

“Yes,” Zheng Ren said.
“Sodium nitroprusside is a kind of nitro-hydrocyanate, a strong dilator that acts directly on the vascular bed of arteries and veins.
Sodium nitroprusside was continuously pumped in.
First, it was converted from erythrocyte to cyanide, and then from thiocyanate in the liver to thiocyanate, the end metabolite.

“Thiocyanate was excreted from the kidney.
The half-life of a person with normal kidney function is four to seven days.
Patients with kidney failure have an accumulation.
If the dosage is too high, poisoning is normal.”

“But the patient has no abnormal kidney function,” Professor Huang said as he tried to recall the patient’s test results.

“There wasn’t before, but now there is.”
