At the same time, a mechanical cold female voice came, not in response to Zheng Ren's shout, but in order to issue a mission.

[Urgent Mission: Ten Thousand Families Live Buddha.]

Mission: Complete the rescue work of large-scale food poisoning in the emergency department.

Reward: For every 100 patients successfully rescued, you will get 300 skill points, 1 silver treasure chest, and 30,000 experience points.

Mission duration: 1 day. 】

The system, which has always been generous, is even more generous this time, and directly gives the task that makes Zheng Ren stunned. The reward was so rich that Zheng Ren couldn't believe that Zheng Ren didn't know what the silver treasure chest could open. Just 300 skill points and 30,000 experience points are enough.

But...... Zheng Ren secretly scolded that there is no femoral vein dissection in the system mall.

Is this specifically teasing me? Zheng Ren is manic.

Every minute, or even second, of delay can lead to the death of the patient.

Suddenly, Zheng Renfu, who was in a manic mood, flashed a thought in his mind, isn't the beginning of interventional surgery arterial puncture?

And now what I want to do is deep vein puncture, although it is different, but the principle is similar.

Get your feet wet?

There was no time to think about it, Zheng Ren clicked on the interventional surgery time to buy, and found that there were options, and the first option was deep vein and deep artery puncture.

Without hesitation, he chose the puncture operation, and Zheng Ren was no longer stingy in terms of time, and directly exchanged all the 14,076 experience points he had accumulated that he was reluctant to spend for the surgical training time.

234.6 minutes, less than 4 hours, that's all the time Jung-in.

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

……

……

Another carload of patients was pulled over, in the same serious condition, in a state of toxic shock.

By the time the patient was deduced to the door of the emergency room, Director Pan had just cut open the skin of the first patient and was carefully separating the subcutaneous tissue, looking for possible signs of the femoral vein.

"Deep vein puncture kit, ready for sterilization. Zheng Ren "woke up", his voice was a little hoarse.

"Push a flat car, quick!"

The patient was carried to the rescue bed as quickly as possible, and Zheng Ren began to operate.

The patient should lie flat, head down and feet high, and the foot of the bed should be raised about 15~25 degrees to increase the venous pressure and fill the veins.

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

Jung In tore the patient's shirt, and the force was so great that it gave people a wild feeling. A 500ml water bottle was placed between the patient's shoulder blades, the patient was relatively thin, and Zheng Ren chose a soft bottle of normal saline.

The goal is to bring the subclavian vein closer to the clavicle and separate the subclavian vein from the apex of the lungs by spreading the thoracic cage, lowering the shoulders and raising the mid-clavicle.

Zheng 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 could easily move towards the superior vena cava.

"Look, the next patient will be in a position first. Zheng Ren wanted to say it loudly, but he didn't expect that his voice was already hoarse, and only a few nurses around him could barely hear it.

"Yes!" the nurses replied.

This position is very easy to pose, the purpose is clear, and it is not difficult to do it.

Wearing gloves, Zheng Ren has a needle in his hand, and he is ready to start after choosing the puncture point.

Zheng Ren did not follow what was written in the textbook, taking 1~2cm below the midpoint of the clavicle as the puncture point, pointing the needle tip direction to the ipsilateral sternoclavicular joint, and the needle insertion angle was horizontal.

He chose to take a puncture point at the subclavian thoracic triangle, which is lateral to the midclavian line of the subclavicle, away from the clavicle.

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

Is Mr. Zheng busy and confused? Why did the puncture point choose the wrong one?

First aid is being given, and Zheng Ren's hand speed is very steady, very fast, and there is no time to remind him. They could only stare at Zheng Ren's hand and watch as Zheng Ren's left hand pressed up.

Zheng Ren uses his left thumb to press down the skin, and when it is at the same level as the clavicle intercostal space, mark horizontally on the lower edge of the thumb, release the thumb, and puncture directly at this point.

This is the experience summarized by Zheng Ren based on thousands of articles on subclavian arteriovenous puncture and his own practice in the systematic training.

In the systematic surgery training, all the test subjects appeared in front of Zheng Ren in a good position, and at first they did it slowly, about three minutes. The later stages get faster and faster, until the last few tens of seconds a test subject.

During the intensive training, Zheng Ren spent 234.6 minutes doing 452 cases of deep venous puncture.

This number of cases may be slightly lower than that of emergency doctors and ICU doctors in some large hospitals, but it can't stand Zheng Ren's completion in one go, all of which are difficult deep venous punctures with low blood pressure and low blood volume.

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

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

One shot, see blood!

It does not conform to the conventional operation, but the effect is particularly obvious, and several senior nurses around Zheng Ren are stunned.

Repeated punctures, repeated temptations, repeated searches, and finally it is like a stroke of luck before entering the vein, and it takes five minutes to be regarded as a master.

But how long did Mr. Zheng take? Not counting the time to put himself in position, it was only 2 minutes? No, there was absolutely no two minutes, it was only 1 minute...... Maybe in less than 1 minute, I blinked my eyes and saw the venous blood backflow.

"Pick up the drip and match Meilan. Zheng Ren held the deep venous puncture tube in his hand, and when he saw that no one continued the next step, his voice was a little higher.

I really couldn't shout, and the anxious mood just now made the body secrete a lot of adrenaline and dopamine, causing the whole person to be in an abnormal state of excitement, and the voice was completely dumb.

"Oooh oh. The old nurse standing beside Zheng Ren woke up from the shock and immediately connected the deep venipuncture line to the infusion line.

"Prescribe the maximum amount, and after the infusion is completed, continue to give empty sugar and gastric lavage. Zheng Ren instructed.

"Yes!" replied immediately to the senior nurses who had been temporarily transferred from several different departments.

Hospitals are like that, if you can do it, there will be countless people who will listen to you. If you can't do it, no matter how you beep, it's useless.

Ask the nurse to fill the medication and position the patient.

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

It was like a general in the barracks giving an order, and all the generals took the order, without a trace of delay.

After sewing a patient, watching the sugar water and Meilan solution dripping in the drip pot in a line, Zheng Ren was a little relieved.

The next patient was already in a position, Zheng Ren took off the sterile gloves, wiped his hands with alcohol gel, opened the next puncture bag, put on the sterile gloves, and began to continue the operation.
