The anesthesiologist is doing anesthesia, the itinerant nurse is establishing a venous channel for the patient, and the instrument nurse is sorting out the sterile bag, waiting to count for a while.

Spinal anesthesia went smoothly. The patient turned his back to himself. Zheng Ren looked at the system panel and ECG monitoring. They referred to each other and were still dew.

Fortunately, Su Yun and Gu Xiaoran are chatting. Lao he is inserting a USB flash disk. It seems that he is ready to put it in good luck. No one noticed himself and had time to think about it carefully.

Coming to the system space again, Zheng Ren clicks to buy surgery.

But this time he did not do surgery to stimulate the experimental body, but watched quietly.

Even without stimulation, the subject still had cardiac arrest after 12 minutes.

Zheng Ren is very helpless. Instead of rescuing the experimental body, he squints and stands in the system operating room thinking about the possible situation.

It's not hemorrhagic shock. It's not that fast. Is it aortic dissection? From the perspective of ECG monitoring, it is really possible for blood pressure and heart rate to fall like a cliff.

It's just that Zheng Ren doesn't think it's very possible. He just writes it down secretly and dissects it later.

In addition, Zheng Ren has no definite idea, or maybe it's the disease that big pig hoof doesn't give a systematic diagnosis?

Or what congenital disease does the patient have?

Anesthesiologist's anesthesia medication mistakes?

Liquid allergy of intravenous infusion?

Countless possibilities were thought out by Zheng Ren and denied one by one in the system operating room.

He checked the fluids needed for anesthesia and rehydration, and then began to dissect the experimental body to determine where there might be problems.

It's not congenital heart disease, aortic dissection, infusion allergy, or

Zheng Ren is investigating the same.

……

……

As time went by, president Yu said with a smile, "Lao he, you're lucky enough to hear enough."

"Ask for a good mouth." Lao he said with a smile: "some time ago, I had an operation on my stomach and intestines. The red wedding dress put by Brother Yun had an infinite cycle, which scared the girl Quan Xiaocao to cry."

"Red wedding dress, what's that?"

"Young children like you have never heard of it. If you are curious, I suggest going home and lying in bed at night." Su Yun said with a smile, "I'm sure I won't let you down. It's a great song."

Yu Zong finished detoxification and began the operation.

"Mr. Yu, is the adhesion strong?" Su Yun glanced at his boss who was closing his eyes in the corner and asked.

Today, the boss is as restless as a mouse before the earthquake. It will be honest, but Su Yun began to feel uneasy.

Normally, the boss is not. Every time he has questions, he proves that he is right. Su Yun attributed this to "women's intuition", which is a metaphysics. There is no way to explain it with science.

And isn't it just to see the nails in the urethra? Why are you there with your eyes closed? If so, you might as well sit down.

No, there must be something wrong!

"The first one is easy to take." Under the general operation, quickly take out the nail closest to the urethral orifice.

On the instrument table, the instrument nurse took a piece of gauze and put it next to the master's hand. The black nail looked ferocious.

It's about 4cm, not particularly sharp and sharp, but it's really scary in the urethra.

Su Yun looked at the nail and looked at Yu Zong's operation carefully.

The operation went smoothly. Yu was a little cautious in the total operation, but the nails were taken out one by one.

"Mr. Yu, you are too careful." Su Yun smiled.

"Be careful, be careful." President Yu said, "the difficulty is at the back. The nail inside probably closed the urethral orifice and didn't pee out after anesthesia. Brother Yun, do you know what I'm worried about?"

"What?"

"I'm going to try if I can take it out. If not, I'll push the nail directly into the bladder and take it out with a cystoscope." Yu Zong said, "I'm worried that once there is a gap in the urethra, a careless urine will spray on my face."

"..." Su Yun heard it and immediately remembered the stent operation for colon cancer he and his boss had done.

At the moment of opening, the air flow was fierce. If the boss hadn't stopped him with a sterile sheet, I'm afraid it wouldn't work if he went back to take four or five baths.

"Then you should be careful." Su Yun did not joke, but seriously warned President Yu, "my boss and I have been a patient with colon tumor. After the stent was opened, I don't know how long I had to defecate..."

Just then, he saw the boss suddenly stand up from the corner of his eye.

"Syringe!" Zheng Ren said in a deep voice.

The voice was loud, low and urgent.

At the same time, the alarm of the monitor suddenly sounded, with a sharp voice, which was about to tear the lucky song into countless pieces.

Yu Zong looked up and was stunned to see that the heart rate on ECG monitoring fell precipitously, and immediately returned to zero, and the ECG was pulled into a straight line.

The speed of change does not give people a chance to respond at all.

"Su Yun, heart press!" Zheng Ren roared, "Lao he, adrenaline 1mg intravenous injection!"

Su Yun came to the left side of the patient's body when Zheng Ren spoke. The height of the operating table was not very suitable. He directly squeezed the patient to the opposite side, then knelt on the operating table and began to do heart compression.

Seeing the patient's cardiac arrest, Lao he was not surprised. On the contrary, at the moment of abnormal fluctuation in ECG monitoring, Lao he felt that his heart was not so nervous as before.

Sure enough, boss Zheng is right!

As for why, Lao he didn't think about it. At the moment of drawing a straight line in his ECG, he rushed to the anesthesiologist like a fire on his ass.

At this time, anesthesiologist Xiao Zhou was stupid. He looked at ECG monitoring incredibly and was just about to adjust the lead.

In his opinion, it should be the problem of wire connection. Otherwise, how could a patient who was still well in the last second stop his heart directly next.

This is unscientific!

Lao he broke off an adrenaline with one hand and pumped the medicine with a syringe in the other hand. At this time, boss Zheng's voice came, adrenaline, already preparing.

Draw the medicine, open the tee, and an adrenaline is pushed in in the shortest time.

The operating room that was just laughing suddenly became solemn.

"Atropine, 0.5mg!"

Lao he's ears trembled slightly. He saw boss Zheng tear open a 50ml syringe.

However, Lao he didn't have time to see what boss Zheng did. He immediately broke off another atropine and injected it intravenously.

"Lidocaine..."

"Atropine..."

"Adrenaline..."

Boss Zheng's voice kept coming. Even in the sharp alarm sound of the monitor, he was still so calm, like a stone on the beach. No matter how fierce the waves were, he always stood there.
