At the same time, a cold female voice came, not answering Zheng Ren's cry, but promulgating the mission.

[Urgent mission: Ten thousand families of Buddhas.

Task content: Complete rescue work for large-scale food poisoning in the emergency department.

Mission reward: For every 100 patients rescued successfully, 300 skill points, 1 silver treasure chest, and 30,000 experience points.

Mission time: 1 day.]

The system, which has always been generous, has been even more generous this time and directly gave a task that shocked Zheng Ren. The reward was so generous that Zheng Ren couldn't believe what the silver treasure chest could produce, Zheng Ren didn't know. Just 300 skills and 30,000 experience points are enough.

But... Zheng Ren cursed inwardly that there was no femoral vein dissection procedure in the system mall.

Is this just teasing me? Zheng Ren is manic.

Every delay of one minute or even one second may lead to death.

Suddenly, Zheng Renfu, who was in a state of madness, had a thought flashed into his mind. Isn’t the beginning of the interventional surgery an arterial puncture?

What I have to do now is deep vein puncture. Although it is different, the principles are similar.

Give it a try?

I had no time to consider it, so Zheng Ren clicked the time to purchase the interventional surgery and found that the option appeared. The first option was deep vein and deep arterial puncture.

He chose the puncture surgery without hesitation. Zheng Ren was no longer stingy in terms of time and directly changed all the 14,076 experience points he had accumulated and reluctant to spend to the surgical training time.

234.6 minutes, less than 4 hours, this is all Zheng Ren’s time.

The system operating room rose from the ground, Zheng Ren entered, dared not delay for a second, took a deep breath, calmed down, and began training.

...

...

Another car of patients was pulled over, and the condition was as serious as that, in a state of toxic shock.

When the patient was deduced at the door of the emergency room, Director Pan had just cut open the skin of the first patient and was carefully isolating the subcutaneous tissue to look for possible signs of the femoral vein.

"Deep vein puncture bag, ready to disinfect." Zheng Ren "wakes up" and his voice is a little hoarse.

"Push a flat car, hurry!"

The patient was transported to the rescue bed as fast as possible, and Zheng Ren began the operation.

The patient lies flat, lowers his head and high feet, and raises the foot of the bed about 15 to 25 degrees to increase the venous pressure to fill the veins.

This is to ensure that the pressure in the vein is higher than atmospheric pressure, so that the risk of air embolism is not prone to occur during deep vein puncture.

Zheng Ren tore the patient's top open, and the strength was so strong that it gave people a wild feeling. A 500ml water bottle was placed directly between the patient's shoulder blades. The patient was relatively thin, so Zheng Ren chose a soft bottle of normal saline.

The purpose is to spread the chest, sag the shoulders, and elevate the middle section of the clavicle, thereby making the subclavian vein close to the clavicle; to separate the subclavian vein from the lung apex.

Zheng Ren then turned the patient's face towards him to reduce the angle between the subclavian vein and the internal jugular vein, so that the catheter can easily move towards the superior vena cava.

"Look at it, the next patient will set up his position first." Zheng Ren wanted to say loudly, but unexpectedly his voice was hoarse, and only a few nurses around him could barely hear it.

"Okay!" the nurses replied.

This position is easy to place and has a clear purpose, so it is not difficult to do it.

After wearing gloves, Zheng Ren was in his hand with one needle, and then he chose the puncture point and was ready to start.

Zheng Ren did not perform deep vein puncture as written in the textbook, using 1 to 2 cm below the midpoint of the clavicle as the puncture point, the needle tip point to the sternoclavicular joint on the same side, and the needle angle is horizontal.

The puncture point he chose was in the subclavian thoracic triangle area, that is, the lateral side of the subclavian midline, and take any point away from the subclavian.

The nurses have also seen subclavian venous puncture, but the patient's blood pressure is not so low and the rescue is not so urgent.

Mr. Zheng was so confused? Why did the puncture point be selected incorrectly?

In the first aid, and Zheng Ren's hand speed was very stable and fast, so there was no time to remind him. They could only stare at Zheng Ren's hand and watched Zheng Ren press his left hand up.

Zheng Ren used his left thumb to press down the skin, and when it was lowered to the same level as the intercostal gap, he marked horizontally at the lower edge of the thumb, loosened his thumb, and pierced directly horizontally at this point.

This is a systematic training session, Zheng Ren summarized his experience based on thousands of literature on subclavian arteriovenous puncture and his own practice.

During the systematic surgical training, all experimental subjects were placed in front of Zheng Ren. The initial slowdown was about three minutes. The later stage was getting faster and faster, until the last few dozen seconds an experimental subject was.

During the training camp, Zheng Ren spent 234.6 minutes to perform 452 deep vein punctures.

This case number may be slightly lower than that of emergency department doctors and ICU doctors in some large hospitals, but Zheng Ren completed it in one breath. All of them were deep venous punctures with high difficulty and low blood pressure and low blood volume.

With high difficulty and great gains, Zheng Ren is fully qualified to be among the top ranks in the country in puncture technology.

No one else has the opportunity to do hundreds of cases of difficult punctures, only the system space can provide such conditions.

One injection, blood is seen!

The operation that did not meet the routine was particularly effective, and several senior nurses around Zheng Ren were stunned.

Why can't this kind of puncture be used for five minutes? Repeated puncture, repeated trials, and repeated searches, and finally, it was like taking a chance to enter the vein. It took five minutes to be considered a master.

But how long did Mr. Zheng take? It only takes 2 minutes without counting the time to move his position? No, it is absolutely not two minutes, only 1 minute... Maybe in less than 1 minute, I blinked my eyes and saw the return of venous blood.

"Come on a little bit, match Meilan." Zheng Ren held a deep vein puncture tube in his hand. Seeing that no one continued to the next step, his voice was a little higher.

I really couldn't shout it out. The anxiety just now caused the body to secrete a lot of adrenaline and dopamine, causing the whole person to be in an abnormally excited state, and his voice became completely dull and dark.

"Oh oh oh." The old nurse standing next to Zheng Ren woke up from the shock and immediately connected the deep vein puncture tube to the infusion tube.

"Open the maximum amount. After the infusion is completed, continue to give empty sugar and wash the stomach." Zheng Ren instructed.

"Yes!" A senior nurse temporarily allocated from several different departments immediately answered.

This is what the hospital is. If you can do it, countless people will listen to you. If you can’t do it, it will be useless no matter how you say it.

Ask the nurse to add medicine and set the position of the patient.

Zheng Ren picked up the needle and thread from the puncture kit and began to fix the deep vein puncture needle.

For example, the general in the military camp ordered the generals to take the order without any delay.

After sewing a patient, Zheng Ren felt relieved as he watched the sugar water and Meilan solution dripped in a line.
Chapter completed!
