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

The lumbar anesthesia went smoothly, with the patient facing away from him, Zheng Ren looked at the system panel and ECG monitoring. The two referenced each other, and they were still dewy.

Fortunately, Su Yun and Gu Xiaoran were chatting, and Old He was plugging in the U disk, and it seemed that he was preparing to have good luck. No one noticed himself, so he had time to think about this matter carefully.

When he came to the system space again, Zheng Ren clicked to buy the surgery.

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

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

Zheng Ren was helpless. He did not rescue the experimental subject, but stood in the system operating room with his eyes narrowed and pondered what might happen.

It’s not hemorrhagic shock, not that fast. Is it an aortic dissection? Judging from the electrocardiogram monitoring, it is really possible that the heart rate will fall sharply.

But Zheng Ren didn't think this possibility was too great. He just took it down secretly and waited for a while to take a look.

Apart from this, Zheng Ren has no certain idea, or maybe it is the disease that the big pig's hooves did not give a systematic diagnosis?

Or do the patient have any congenital diseases?

Anesthesiologist's anesthesia medication error?

Fluid allergies in intravenous infusion?

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

He checked the liquid for anesthesia and started to dissect the experiment and determined the place where the problem might occur.

It's not congenital heart disease, it's not aortic dissection, it's not an infusion allergy, it's not...

Zheng Ren is investigating them all.

...

...

As time passed by minute by minute, Mr. Yu sanitized and laid a sterile sheet, he smiled and said, "Old He, you can't hear enough of your good luck."

"Can you have a good reputation?" Lao He said with a smile: "A while ago, a gastrointestinal surgery was performed. The red wedding dress Yun Ge'er put on was still indefinitely circulating, which scared Quan Xiaocao, the girl."

"Red wedding dress, what is that?"

"You must have never heard of a young child like you. If you are curious, I suggest going home and lying in the bed to listen." Su Yun said with a smile, "It will definitely not disappoint you. It's a great song."

Mr. Yu finished disinfection and started the operation.

"Mr. Yu, is it so sticky?" Su Yun looked at his boss who was resting in the corner and asked.

Today, the boss was restless like a mouse before the earthquake. Now he became honest, but Su Yun began to feel nervous.

In theory, the boss is not the case. Every time he has questions, he proves that he is right afterwards. Su Yun attributes this to "women's intuition", which is a kind of metaphysics and cannot be explained by science.

And Isn’t I going to the stage just to see the nails in the urethra? Why are you closing your eyes to rest? If this is the case, it’s better to sit down below.

No, there must be something wrong!

"The first one is easy to get." After Mr. Yu's operation, he quickly took out a nail closest to the urethra opening.

On the instrument table, the instrument nurse took a piece of gauze and placed it next to Mr. Yu's hand. The black nail looked a little hideous.

It is about 4cm, not particularly sharp or sharp, but this thing is really scary in the urethra.

Su Yun looked at the nails and carefully watched Mr. Yu's operation.

The operation was relatively smooth, and Mr. Yu was a little cautious in his operation, but he still took out one nail after another.

"Mr. Yu, you are too careful." Su Yun said with a smile.

"Be careful, be careful." Mr. Yu said: "The difficulty lies at the end. The nail inside probably closed the urethra opening, and he didn't even urinate after anesthesia. Brother Yun, do you know what I'm worried about?"

"What?"

"I'm going to try to remove it. If it doesn't work, I'll just push the nail into my bladder and then use a cystoscope to remove it." Yu said, "I'm worried that once there is a gap in the urethra, I'll spit my face inattention."

"..." Su Yun heard this and immediately remembered the colon cancer stent surgery he and his boss had.

The moment I stretched out, the air flow was fierce. If the boss hadn't stopped him with sterile help, I would have been so bad that I would have gone back and took a shower four or five times.

"Then you have to be careful." Su Yun did not joke, but seriously warned Mr. Yu, "My boss and I had a patient with a colon tumor. After the stent was opened, I don't know how long it took to stool..."

As he was talking, he saw the boss suddenly stand up from the corner of his eyes.

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

The voice was very loud, very low, and there was a sense of urgency.

At the same time, the monitor alarm suddenly sounded, and the sound was sharp, and it was about to tear the song of good luck into countless pieces.

Mr. Yu looked up and was shocked to see the cliff-like decline of the heart rate on the ECG monitoring. He immediately returned to zero, and the ECG pulled into a straight line.

The speed of change is so fast that it does not give people a slight chance of reaction.

"Su Yun, heart pressure!" Zheng Ren yelled, "Lao He, 1mg of adrenaline intravenous injection!"

Su Yun had already reached the left side of the patient's body when Zheng Ren was speaking. 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 started to do heart compression.

When Lao He saw the patient's cardiac arrest, he was not surprised. Instead, at the moment when the electrocardiogram monitoring showed abnormal fluctuations, Lao He felt that his heart was not as nervous as before.

Sure enough, Boss Zheng is right!

As for why, Lao He didn't think about it. The moment he pulled the electrocardiogram straight, he rushed to the anesthesiologist like a fire broke out on his butt.

At this time, the anesthesiologist Xiao Zhou was stunned. He looked at the ECG monitoring in disbelief, just about to adjust the wire.

In his opinion, it should be a problem with wire connection, otherwise, the patient would have been fine in the last second, so how could the heart stop immediately?

This is unscientific!

Lao He broke a stick of adrenaline with one hand and held a syringe in the other hand to draw medication. At this moment, Boss Zheng's voice came, and adrenaline was already preparing.

Draw the medicine and turn on the tee, and an adrenaline was pushed in in the shortest time.

The operating room, which was still laughing just now, became solemn in an instant.

“Atropine, 0.5mg!”

Old He's ears trembled slightly, and he saw Boss Zheng tearing a 50ml syringe open.

However, Lao He didn't have time to see what Boss Zheng did, so he immediately opened another atropine and gave an intravenous injection.

“Lidocaine…”

"atropine……"

"Erepinephrine..."
