After having a late-night snack in Liu Ziang's neurosurgery office, Zhao Heng returned to the anesthesiology department and checked the time. It was already four in the morning.

Such nights were also a norm for Zhao Heng.

Choosing the profession of a doctor is equivalent to choosing such a life of day and night inversion.

Statistics show that the probability of sudden death for surgeons, especially anesthetists, ranks among the top three of all professions.

Standing in front of the office window, Zhao Heng looked outside. At four in the morning, North City still looked bustling.

It was already four in the morning, and being unable to sleep, Zhao Heng sat down at the computer. It was time to finish the paper on the impact of anesthetics on organs.

Finishing this paper, along with the previous one on brain function and consciousness recovery, Zhao Heng would have established a preliminary foothold in the academic world.

Once Old Huang returns to the country, applying for the continuous master's and PhD program must be brought to schedule.

As for professions, at the Eastern Hospital, Zhao Heng hasn't exhausted the skills and experiences from other surgeons, occasionally picking up related skills and experience from them.

As of now, Zhao Heng can be said to be a rare doctor proficient in all departments.

Being proficient in so many medical fields gives Zhao Heng a completely different perspective on medicine and treatment compared to other doctors.

Anesthesia is just an entry point.

For Zhao Heng, the future holds endless possibilities.

Turning on the computer, Zhao Heng put on his Bluetooth headset, took out his phone, swiped up the NetEase Cloud Music, and played a song by female anchor singer Xu Xu Man, "The Singer".

"I saw my love

I flew to her side

I presented her with a gift

It was a small piece of solidified time"

In the earphones, a melodious yet full female voice came through.

This song, which Zhao Heng recently enjoyed listening to, is sung by a female anchor. It's the theme song of the final season of the "Three-Body" radio drama.

The time devoted to writing the paper passed quickly, and finally, Zhao Heng finished the last word of this twelve-page paper.

Raising his head, Zhao Heng saw the window was already bright, and checking the time, it was already seven-thirty in the morning.

Zhao Heng stood up, stretched, and once again headed to the neurosurgery intensive care unit.

Just as Zhao Heng entered, Liu Ziang was also there.

It seems he was still very concerned about the patient's condition.

"Senior, how is the patient's condition?"

Zhao Heng asked Liu Ziang, who was standing by the bedside with a not-so-relaxed expression.

"It's very bad. Due to extensive electrical burns and carbonization of the surface skin, the patient now has a severe infection and is also showing signs of DIC."

Liu Ziang shook his head slightly and said.

For this patient who can be said to have been pulled back from the hands of death, of course, Liu Ziang hopes he can recover.

But reality is disappointing. Being able to withstand getting onto the operating table and surviving off it is already extraordinarily lucky!

What Liu Ziang referred to as DIC is disseminated intravascular coagulation, where the coagulation mechanism is diffusely activated inside the blood, triggering widespread fibrin deposition in small vessels, leading to tissue and organ damage; on the other hand, the consumption of coagulation factors results in a systemic bleeding tendency.

These two contradictory manifestations coexist during the development of DIC disease and constitute its unique clinical presentation.

In DIC, multiple organ dysfunction syndrome becomes the main cause of death for patients.

Most importantly, the mortality rate for DIC is as high as 31% to 80%.

"The patient now needs a large amount of blood transfusion, but with too much transfusion, the likelihood of allergies, fever, and transfusion-associated circulatory overload is very high."

After a pause, Liu Ziang said with concern again.

It's rare to see Liu Ziang so worried, it seems the patient's condition is really very tricky and not optimistic.

The transfusion here is essentially the infusion of large amounts of "allo-geneic red blood cells", the supernatant of which may contain cytokines, chemokines, and cell-derived particles that trigger a pro-inflammatory response in the recipient's immune system.

"In that case, wouldn't it be better to wash the allo-geneic red blood cells before transfusion?"

Zhao Xu pondered for a moment and said.

This inspiration came from dialysis.

"Since allo-geneic transfusion has some side effects, the allo-geneic red blood cells can be washed at the bedside as needed, removing some soluble factors and reducing the concentration of soluble factors associated with adverse transfusion reactions."

"Moreover, washing allo-geneic red blood cells can remove cytokines, chemokines, and microparticles associated with transfusion-related respiratory complications, significantly reducing the possibility of antibody-mediated, transfusion-related acute lung injury by effectively removing the majority of proteins."

Pausing, Zhao Heng said again.

"Hmm, this idea sounds feasible."

After listening to Zhao Heng's suggestion, Liu Ziang thought for a moment, and his heavy expression noticeably lightened, looking at Zhao Heng with greater appreciation.

In his view, not only is Zhao Heng highly professionally competent, but what's more valuable is his capability to practically solve problems, which is very strong.

When other doctors are at a loss, Zhao Heng always can propose effective treatment plans from a unique angle that others haven't thought of.

This ability is extremely rare.

Professional competence can be trained, but how can thinking be trained?

"Go and rest for a bit. With the idea you proposed, the patient's survival probability has greatly increased."

Liu Ziang said to Zhao Heng again.

Actually, tonight's surgery, Zhao Heng was more exhausted than both him and Jiang Rui.

After all, both he and Jiang Rui were only in charge of a part of the surgery and could rest a little during the process, but Zhao Heng stayed throughout the surgery, having to constantly monitor the patient's vital signs and adjust the intra-operative medication, which adds tremendous mental pressure on a person.

These, Liu Ziang had seen with his own eyes.

"Alright, call me if there's anything."

Zhao Heng nodded.

"No worries, I'll contact the nephrology department doctors to handle the allo-geneic red blood cell washing."

Liu Ziang said.

The allo-geneic red blood cell washing process is actually quite similar to dialysis.

Zhao Heng nodded, realizing he was, indeed, exhausted.

Upon returning from neurosurgery, Zhao Heng checked the time and it was already ten past eight. At this moment, those who arrived early had already started their shifts.

Sitting in the office, Zhao Heng was about to hand over his duty and then head back to rest.

Just then, Xu Man Ni entered from outside the office and, seeing Zhao Heng looking wearied with two large dark circles under his eyes, she couldn't help but say with great concern, "Why did you pull an all-nighter again?"

"There was a patient in neurosurgery that required my cooperation for anesthesia."

Zhao Heng replied with a smile.

"Ha? Again with Liu Ziang? Why does he always drag you into these major surgeries that go through the night? I must have a word with him."

Upon hearing it was another surgery with Liu Ziang, Xu Man Ni couldn't help but exclaim.

Anything involving Liu Ziang usually means no surgery is easy, and they're always the type that can last an entire night.

"It's fine, I'll just go back to sleep after handing over the shift."

Zhao Heng said with a smile.
