Soon, Liu Ziang, along with two resident doctors, started the surgery.

After the surgery began, Zhao Heng closely monitored the life-support monitor, especially the patient's blood pressure.

On Liu Ziang's side, they had already begun drilling the skull in preparation for removing the bone flap.

To put it plainly, they were preparing to open the patient's skull.

Just as Liu Ziang was holding the bone drill, slowly opening the sutures and the skull, Zhao Heng noticed a significant drop in the patient's blood pressure.

95/50 88/45 70/38 55/32...

Seeing the patient's blood pressure drop so suddenly, reaching shock levels, Zhao Heng immediately said to the circulating nurse, Sun Meng, "Administer 30 micrograms of adrenaline, quickly!"

Sun Meng immediately picked up the syringe, drew 30 micrograms of adrenaline, and injected it directly through the IV line.

With such a large dose of adrenaline injected, the blood pressure rose slightly but still remained at a very low level.

"Norepinephrine, adrenaline infusion, maintain at 1 microgram,"

Zhao Heng said to Sun Meng again.

Sun Meng immediately acted and connected the infusion pump with added norepinephrine and adrenaline to the patient's vein.

With this measure in place, Zhao Heng saw that the patient's blood pressure finally stabilized around 70/38, though still very low, it had become relatively stable.

After completing this series of steps to raise the patient's blood pressure, Liu Ziang had already removed the skull, and it was evident that there was a shocking dent on it, suggesting that the patient must have suffered a severe blow to the head during the car accident.

"How is it?"

Liu Ziang placed the removed skull on the workbench and turned to ask Zhao Heng.

He was aware of the patient's sudden drop in blood pressure earlier, but he couldn't stop his procedure.

Performing intracranial surgery requires extreme caution; almost every structure is critical, and even a small mistake could have widespread effects.

"The blood pressure maintenance isn't great; we need to hurry and finish this."

Zhao Heng shook his head slightly and said.

If the patient's blood pressure dropped suddenly again, Zhao Heng wasn't sure he could bring it back up.

Earlier, to raise the patient's blood pressure, Zhao Heng had already used norepinephrine and adrenaline, both of which are normally used only in cases of cardiac arrest or severe hemorrhagic shock.

"Alright, I'll leave it to you."

Liu Ziang said seriously.

It felt like being comrades on a battlefield.

In reality, they were comrades; the operating room was nothing short of a battlefield between life and death.

It wasn't easy for Liu Ziang either; the patient's skull sustained a severe impact, causing massive intracranial bleeding. To repair the vessels, they must first clean up all these blood clots and then locate the damaged vessels.

Since the surgery was on the brain, every step must be highly focused, and not a single mistake could be made.

Next, Liu Ziang continued with the surgery.

"Start autologous blood transfusion."

Zhao Heng said to Sun Meng again.

The autologous blood transfusion was Zhao Heng's pre-prepared measure to prevent the situation where massive blood loss would lead to shock and inadequate blood volume causing a sudden drop in blood pressure.

"Okay."

Upon receiving Zhao Heng's instruction, Sun Meng nodded and promptly carried out the action.

After this series of operations, Zhao Heng saw that the patient's blood pressure had finally stabilized, and he breathed a sigh of relief.

Who says anesthetists just sit in the operating room, play with their phones, and wait for the main surgeon to finish the surgery?

In many cases, the patient's life and death are in the anesthetist's hands.

With the patient's blood pressure stabilized, Zhao Heng finally exhaled and took a good look at Liu Ziang performing the surgery.

Liu Ziang is a renowned neurosurgeon in the country, and watching him operate is indeed valuable.

Sure enough, after just watching for a while, Zhao Heng saw a white light orb that he was very familiar with fall from Liu Ziang.

With a practiced mind, Zhao Heng willed it, and the white light orb transformed into a stream of light and entered Zhao Heng's mind.

[Ding! Picked up an Emergency Brain Vascular Repair Technique (Perfect)]

Wow!

It turned out to be a perfect skill.

Liu Ziang truly deserves to be a famous neurosurgeon in the country.

Absorbing this skill light orb, Zhao Heng couldn't help but feel a sense of awe in his heart.

Doctors capable of dropping skills at the Perfect Level are exceedingly rare and one in a million.

Soon, integrating the Emergency Brain Vascular Repair Technique he absorbed from Liu Ziang, Zhao Heng became very adept at the path, repair of cerebral vessels, and how to minimize operating damage to brain tissue during surgery.

After all, it's a skill derived from the great master Liu Ziang, naturally extraordinary.

Just as Zhao Heng was organizing the skill experiences fused in his mind, Liu Ziang's actions suddenly came to a halt.

Because he encountered an extremely tricky situation.

"What's wrong?"

Seeing Liu Ziang's movement pause, Zhao Heng stood up, puzzled, and asked.

"Come and take a look."

Liu Ziang said briefly.

Hearing this, Zhao Heng walked over, stood by the operating table, and looked in the direction Liu Ziang pointed. Zhao Heng saw a fava bean-sized lump on a cerebral artery, still pulsating with the artery's beat.

"Is this a cerebral artery aneurysm?!"

Zhao Heng was instantly shocked.

The patient was initially suffering from acute cranial trauma, a condition already critical enough, but now how could there be an aneurysm found on the patient's cerebral artery?

This was simply adding insult to injury.

The cerebral artery aneurysm is the "ticking time bomb" that all neurosurgeons dread!

If this aneurysm on the cerebral artery ruptures, the patient would suffer anything from full paralysis to instant death.

The best outcome would be ending up in a vegetative state.

And now, with the patient's already unstable blood pressure, Liu Ziang was pressured to quickly finish the surgery, and yet there's such a ticking time bomb in the form of a cerebral artery aneurysm.

What should be done?

If this aneurysm isn't addressed, and it ruptures post-operatively, given the patient's condition, they might not even survive to reach the operating table.

Moreover, in neurosurgery, even performing a cerebral artery aneurysm operation alone is extremely hazardous and complex, let alone under emergency conditions.

The most troublesome point is that the patient's blood pressure isn't well controlled, and there's always the potential for a sudden drop in blood pressure, while the surgery must be completed quickly.

It's as if all the most critical issues have come together at once.

"Yes."

Liu Ziang nodded solemnly.

Whether it's traumatic vascular repair or aneurysm surgery, Liu Ziang is confident in completing them.

But combining these two with limited surgery time, he couldn't possibly split into two, and there's simply not enough time to complete them.

Thinking of this, even the grandmaster neurosurgeon Liu Ziang felt a sense of his scalp tingling!
