At the same time, a mechanical and cold female voice came, not answering Zheng Ren's cry, but issuing a mission.
Urgent task: Thousands of families have Buddhas.
Mission content: Complete the rescue work of large-scale food poisoning in the emergency department.
Mission reward: For every 100 patients successfully rescued, you will receive 300 skill points, 1 silver treasure chest, and 30,000 experience points.
Task time: 1 day.
The system, which has always been generous, was even more generous this time and directly gave Zheng Ren a task that stunned him. The rewards were so generous that Zheng Ren couldn't believe it. Zheng Ren didn't know what the silver treasure chest could bring out. Just 300 skill points and 30,000 experience points are enough.
But... Zheng Ren secretly cursed that there was no femoral vein dissection procedure in the system mall.
Are you kidding me? Zheng Ren was furious.
Every minute or even second of delay could result in the patient's death.
Suddenly, Zheng Renfu, who was in a state of mania, reached into his mind, and an idea flashed in his mind. Isn't the beginning of the interventional surgery just arterial puncture
What I want to do now is deep vein puncture. Although it is different, the principle is similar.
Give it a try
With no time to think about it, Zheng Ren clicked on the interventional surgery time to purchase and found options. The first option was deep vein puncture or deep artery puncture.
He chose puncture surgery without hesitation, and Zheng Ren was no longer stingy about time. He directly exchanged all the 14,076 experience points he had accumulated and was reluctant to spend into surgical training time.
234.6 minutes, less than 4 hours, is all Zheng Ren’s time.
The system operating room rose from the ground. Zheng Ren entered, not daring to waste a second. He took a deep breath, calmed down and started training.
…
…
Another carload of patients was pulled over. Their condition was equally serious and they were in a state of toxic shock.
By the time the patient was escorted to the door of the emergency room, Director Pan had just incised the first patient's skin and was carefully separating the subcutaneous tissue, looking for possible signs of the femoral vein.
"Deep venipuncture bag, ready for disinfection." Zheng Ren woke up, his voice a little hoarse.
"A flat car is coming, hurry!"
The patient was moved to the emergency bed as quickly as possible, and Zheng Ren began the operation.
The patient lies supine with the head down and the feet up, with the feet of the bed elevated about 15 to 25 degrees to increase venous pressure and 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 less likely to occur during deep vein puncture.
Zheng Ren tore off the patient's shirt with such force that it gave people a wild feeling. A 500ml water bottle was placed directly between the patient's shoulder blades. This patient was relatively thin, so Zheng Ren chose a soft bottle of normal saline.
The purpose is to expand the chest, droop the shoulders, and elevate the middle part of the clavicle, thereby bringing the subclavian vein closer to the clavicle and separating the subclavian vein from the lung apex.
Zheng Ren then turned the patient's face toward himself to reduce the angle between the subclavian vein and the internal jugular vein, making it easier for the catheter to move toward the superior vena cava.
"Look, let's position the next patient first." Zheng Ren wanted to say loudly, but unexpectedly his voice was already hoarse, and only a few nurses around him could barely hear it.
"Okay!" the nurses replied.
This position is easy to achieve, has a clear purpose, and is not difficult to achieve.
Wearing gloves, Zheng Ren held the needle in his hand, selected the puncture point and was ready to start.
Zheng Ren did not follow the instructions in the textbook, which was to perform deep vein puncture with the puncture point 1 to 2 cm below the midpoint of the clavicle, the needle tip pointing toward the sternoclavicular joint on the same side, and the needle insertion angle being horizontal.
The puncture point he chose was in the subclavian thoracic triangle, that is, just outside the subclavian midclavicular line, and any point away from the subclavian was chosen.
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 confused? Why was the puncture point selected incorrectly
First aid was being given, and Zheng Ren's hand speed was very steady and fast, and there was no time to remind him. They could only stare at Zheng Ren's hand, watching helplessly as Zheng Ren pressed forward with his left hand.
Zheng Ren used his left thumb to press down the skin until it was at the same level as the intercostal space. He made a horizontal mark on the lower edge of his thumb, released his thumb, and punctured directly at this point.
This is the experience Zheng Ren summed up during the systematic training based on thousands of documents on subclavian artery and vein puncture and his own practice.
During the system surgery training, all the experimental subjects appeared in front of Zheng Ren in a well-positioned position. At first, they were done slowly, taking about three minutes. The later stages are getting faster and faster, until there is only one experimental subject in the last few dozen seconds.
During the training session, Zheng Ren performed 452 deep vein punctures in 234.6 minutes.
This number of cases may be slightly lower than that of emergency doctors and ICU doctors in some large hospitals, but Zheng Ren could not stand it and completed it in one go. All of them were difficult deep vein punctures of experimental subjects with low blood pressure and low blood volume.
The difficulty is high and the rewards are great. Zheng Ren is fully qualified to be among the best in the country in puncture technology.
Others don't have the opportunity to perform hundreds of difficult punctures. Only the system space can provide such conditions.
One shot, blood!
It was an unconventional operation, but the effect was particularly obvious. Several senior nurses around Zheng Ren were stunned.
Why can't a puncture of this difficulty be performed every five minutes? After repeated punctures, repeated tests, and repeated searches, it finally entered the vein as if by luck. It took only five minutes to become a master.
But how long did Mr. Zheng use it? Not counting the time for positioning, it’s only 2 minutes? No, definitely not two minutes, just one minute... maybe even less than one minute. In the blink of an eye, I could already see the venous blood returning.
"Take the drip and add Meilan." Zheng Ren held the deep venipuncture tube in his hand. Seeing that no one was taking the next step, Zheng Ren's voice became louder.
I really couldn't shout. The anxiety just now caused the body to secrete a large amount of adrenaline and dopamine, causing the whole person to be in an abnormally excited state, and the voice was completely muted.
"Oh oh oh." The old nurse standing next to Zheng Ren woke up from the shock and immediately connected the deep venous puncture tube to the infusion tube.
"Prescribe the maximum amount. After the infusion is completed, continue to give sugar and gastric lavage." Zheng Ren instructed.
"Yes!" Several senior nurses temporarily assigned from different departments immediately answered.
This is what hospitals are like. If you can do it, countless people will listen to you. If you can't do it, no matter how much you beep, it's useless.
Let the nurse add medicine and position the patient.
Zheng Ren picked up the needle and thread in the puncture kit and began to fix the deep venous puncture needle.
It was like a general giving an order in a military camp, and all the generals followed it without any delay.
After sewing a patient, Zheng Ren felt relieved when he watched the sugar water and melan solution dripping in a line from the drip pot.
The next patient was already positioned. Zheng Ren took off his sterile gloves, wiped his hands with alcohol gel, opened the next puncture bag, put on sterile gloves, and began to continue the operation.
