Rebirth of a Doctor Without Regrets

At 2 a.m., an ambulance sped along the Second Ring Road in Beijing.

Wang Xiao got into the car in a daze, wondering why this hadn't happened in his previous life. Could it be that something had changed in the timeline after his rebirth?

Perhaps in my past life I was so focused on treating other wounded that I didn't notice this critically injured person at all.

Chen Yuchen's wound continued to bleed, and her blood pressure continued to drop slowly.

The wound area of ​​the amputated limb is too large, and tourniquet alone cannot stop the bleeding from capillaries and small veins. Only gauze can be used to apply pressure to the wound surface temporarily.

The nurse kept talking to Chen Yuchen to keep her awake.

But her mind became increasingly confused, and she began to speak incoherently. Seeing this, Wang Xiao took out the prepared blood, and the nurse changed the blood and increased the IV fluid volume.

Blood pressure returned to a stable level, and blood oxygen saturation rose to 96%.

A mechanical voice sounded in Wang Xiao's ear.

【Ding! 】

[An impending surgery has been detected.]

[Perfect Surgical System activated.]

What kind of surgery? This is completely baffling.

Is it a system standard for reborn individuals?

Suddenly the driver screamed, the ambulance swerved, and the vehicle jolted violently.

"You bastard! You scared me half to death! The manhole cover thief should be shot!" the driver cursed in a thick Beijing accent.

There are quite a few people stealing manhole covers these days.

Blood gushed from the wound, covering the carriage, the rear door, and both sides of Wang Xiao and the accompanying doctor.

The monitor started alarming, and my blood pressure dropped to 110/69 mmHg in an instant.

Wang Xiao and the accompanying doctor tried their best to press the gauze tightly against the wound, but the bleeding did not decrease at all.

"Increase the blood transfusion! Give me the tourniquet, I want to reapply it!" Wang Xiao shouted.

"It's no use. The blood vessels have been compressed for so long that they have lost their ability to contract and stop bleeding. Applying a tourniquet again will only compress the swollen and damaged tissue. It won't close without a blood clot." The accompanying doctor's hands were trembling and covered in blood. "With such heavy bleeding, it would most likely be impossible to stop even in the operating room."

Wang Xiao looked at the nurses; senior nurses often have far superior operational skills compared to ordinary doctors.

The nurse could only shake her head helplessly and silently turn the IV drip to the maximum.

"Am I...am I going to die? I'll never race again, sob sob sob...I'll never do it again..."

Just moments ago, Chen Yuchen was bravely comforting her companions, but now she could no longer hold on. Her shoulders trembled uncontrollably, her lips quivered, and she managed to squeeze out sobs from her throat.

No one could bear to hear this, so Wang Xiao said excitedly, "Don't be afraid, child, we won't let anything happen to you!"

The nurse was taken aback. Wasn't this young doctor only in his early twenties? Why was he calling her "kid"?

Wang Xiao reached out to the nurse, "Forget about my leg, saving my life is the priority. Give me...give me the ultrasonic scalpel!"

In order to reattach a severed limb, doctors will try their best to protect the nerves and blood vessels at the wound site, but this also increases the risk of bleeding.

Since massive bleeding has already occurred, immediately closing the severed ends of the blood vessel is the only option.

The most common approach is to cauterize the severed ends of the blood vessels, but this treatment would disrupt the conditions for limb replantation.

"Where can you find an ultrasonic scalpel in an ambulance? You don't even have an electrocautery scalpel, you only have this." The nurse handed over a portable electrocautery pen.

When Wang Xiao took a look, he realized it was some kind of old-fashioned junk from the past.

Common tools for closing blood vessels include electrocautery and ultrasonic scalpels. These methods use high-frequency current or high-frequency vibration to evaporate the blood and denature proteins to form an adhesive layer.

The hemostatic pen is essentially a miniature version of an electric scalpel.

As a professional salesperson, Wang Xiao not only studies her own company's products, but also knows her competitors inside and out.

The hemostatic pen in my hand is rechargeable and has low power, so it's useless for dealing with severe bleeding and is only effective for small blood vessel oozing.

Is it necessary to treat minor bleeding from small blood vessels in an ambulance?

This thing is only suitable for outdoor hikers to use in emergencies.

The product manager who developed this product must have lost their mind; they have absolutely no understanding of the market.

Wang Xiao gritted his teeth and shoved the hemostatic pen into the injured person's wound, trying to see if he could burn the bleeding point.

On this fountain-like wound, Wang Xiao experienced a feeling of helplessness, like trying to cut water with a knife.

The car was filled with a burnt smell, and the bleeding began to gradually decrease.

Does this work too?

Wang Xiao turned around and saw that Chen Yuchen had lost consciousness, the monitor was still alarming, and her blood pressure had dropped to 80/40 mmHg.

"We've run out of blood. Now we can only administer crystalloid solution," the nurse said.

【Ding! 】

The patient went into hemorrhagic shock. The surgery failed.

The world dissolves before Wang Xiao's eyes and then unfolds again.

The nurse had just changed the blood bag, and the car was not yet covered in blood.

Holy crap? I really do have a cheat code!

Wang Xiao suppressed countless doubts and thoughts in his mind and instinctively pressed down on the tourniquet that was about to burst.

Sure enough, the ambulance lurched violently, and the driver's curses could be heard.

Wang Xiao felt as if there was an inflating balloon in his palm, which then burst with a "pop".

The tourniquet broke, but because of Wang Xiao's pressure, the bleeding didn't spurt out this time; it just flowed into the stretcher and the ambulance.

"Oh no... this is terrible..." The accompanying internist panicked again.

"Think of a solution quickly!" Wang Xiao interrupted him impatiently.

The nurse remained calm and increased the blood transfusion volume on her own.

Senior nurses may not be able to make diagnoses, but they are often much more skilled than doctors in practical operations.

"Nurse, is there any way to stop the bleeding?" This time, Wang Xiao didn't act rashly, but instead considered effective methods first.

"The usual methods are no longer working... Why don't you try clamping the severed end of her aorta with forceps, and then we'll apply a tourniquet to reduce bleeding from other small blood vessels?" The nurse took out the forceps.

"Impossible. Even if you dissect it, it would be difficult to find the bleeding point in the blood vessel, not to mention there's no surgical field in the blood flow." The on-board doctor didn't believe the nurse at all.

Nurses in that era typically lacked theoretical knowledge, and older generations of doctors generally looked down on nurses.

"Stop talking! Help me hold down the top." Wang Xiao took the hemostat and began trying to find the artery in the wound.

The wound was a bloody mess, with broken bones, fat layers, muscles, and nerves, some tangled together, others in pieces. The anatomical structure had been destroyed, and with blood constantly flowing out, nothing could be seen clearly.

Wang Xiao inserted the hemostat along the direction of blood flow and closed it by feel.

The bleeding did not decrease, and the artery was not clamped.

"Again!" Wang Xiao encouraged himself, but his hands began to tremble.

I closed it again based on my senses.

The bleeding has not decreased significantly, and the blood pressure has dropped to 86/49 mmHg.

There's almost no chance left, and they still can't find the artery at all.

"Try it with your hands, feel it with your hands," the nurse reminded Wang Xiao.

Wang Xiao then pinched the tip of the pliers and reached deep into the severed leg to search for the artery.

Wang Xiao could clearly feel the direction of the bleeding with his hand, and once again clamped his hand shut by feeling.

The bleeding has decreased somewhat, it seems that a small artery has been clamped, but the bleeding still can't be stopped.

The last blood bag was empty.

【Ding! 】

The patient went into hemorrhagic shock. The surgery failed.

"It's over...it's over..." The accompanying internist panicked again.

"Here it comes again...here it comes again..." Wang Xiao was also numb.
