Zhou Ce came quickly. He looked at Sun Lien, who was locked up in the clean room, with a surprised face, and after being stunned for a long time, he asked, "You also stole the little nurse's underwear?"

"Huh?" Sun Lien looked confused, "What?"

"Oh, it's okay. Zhou Ce waved his hand very calmly, "That was a story from a long time ago. ”

Sun Lien looked at Zhou Ce suspiciously, and only after a long time did he twist his eyebrows and ask, "Doctor Zhou, I want to ask, this dialysis equipment...... How to install. ”

"Dialysis?" Zhou Ce thought for a while and shook his head, "Why are you asking this?

"Suspected avian flu. Sun Lien pointed to the hospital bed behind him, regardless of whether Zhou Ce could see it or not. "All three cylinders of the protective clothing were used, and it took some time to inflate them. Patient's condition...... Not so good. ”

"Is there an inspection report?" Zhou Ce quickly understood the current situation, and didn't talk nonsense, and asked directly, "How much urine is there?"

"The examination report has not come out yet, and it has been two hours since I was admitted to the hospital, and the amount of urine is about 15 ml. Sun Lien squatted down and picked up the urine bag hanging next to the bed and took a look. "Since admission, more than 500 millilitres of fluids have been given to the patient. ”

"The urine output is a little low, but you have to read the report to confirm whether there is acute kidney injury. Zhou Ce thought for a while, "I'll teach you how to connect first." ”

Dialysis machines have evolved over the generations to become fairly easy to use. Unlike peritoneal dialysis, the basic principle of a dialysis machine is to "filter the blood". Blood is drawn from an artery, filtered through a supertonic membrane, and returned to the vein to remove impurities. Peritoneal dialysis, on the other hand, makes more use of the structural characteristics of the human body itself, using the semi-permeable membrane properties of the peritoneum to adsorb and filter impurities by injecting and extracting dialysate.

Although DIC itself is one of the scope of peritoneal dialysis, the use of peritoneal dialysis requires the placement of a dialysis tube in the peritoneum. In the current situation, Sun Lien alone will definitely not be able to complete this kind of operation. Therefore, Zhou Ce did not consider peritoneal dialysis at all, but directly chose to let Sun Lien learn to connect to the dialysis machine.

"Dialyzers come with a bag that contains two clear hoses. Zhou Ce raised the transparent bag he was holding in his hand, "After opening it, you will find that there are two thick tubes with needles inside, one with a blue label and the other with a red label." ”

Sun Lien unpacked an operation bag in the room, "And then?"

"Then, tighten all the pathways on the machine and inject saline through the red port. Zhou Ce threw away the operation bag in his hand, grabbed a bag of normal saline, and explained like a big horse monkey, "It is not possible to connect the normal saline directly with the intravenous infusion pipe! The intravenous infusion pipe is not thick enough, and the connecting pipe must be used!"

"Okay, okay, I see. Sun Lien motioned for Zhou Ce to calm down, "I remember." ”

"Brother, this is helping you deepen your impression. If you kid forgets to pre-punch and pop the bubbles in, then the fun will be great. Zhou Ce said solemnly, "Before I think you remember, shut up and listen, don't interrupt my train of thought!"

Sun Lien smiled bitterly and agreed, and by the way, he took out a notebook from his pocket and wrote notes.

"The machine in our yard requires 1,000 ml of pre-flushing, so you can honestly flush it. Don't reduce the impulse to save time, if there are bubbles, it will kill you. Zhou Ce emphasized it again, and then continued to explain.

"The brine from the flush tube will be discharged from the waste port, and you can collect it with the waste collection bag in the operation bag. The saline solution is then drawn with a syringe and injected into a red-labeled tube first. After the injection site is disinfected, the patient is pricked. Remember, this red-labeled tube pierces the artery. ”

"Pulse puncture with a red label tube...... Sun Lien quickly made a few strokes, "and then the blue label tube punctures the vein?"

"Clever!" Zhou Ce praised Sun Lien expressionlessly, "This sentence is to show encouragement, and it doesn't matter if you can ignore the content." ”

Sun Lien smiled bitterly and nodded, he was really not used to Zhou Ce's startled and occasionally sullen character.

"After both tubes have returned blood, heparin is poured into the tube for anticoagulation. He flipped through the test report in his hand, "Generally, we use the standard injection of low molecular weight heparin at 60~80IU/kg, but since this patient is already doing anticoagulation therapy, we will inject according to the standard of 30IU/kg." You can estimate her weight. ”

"After flushing, the red label tube is connected to the red arterial approach, and the blue label tube is connected to the blue venous exit. If you get this very basic thing wrong, you can consider quitting. Zhou Ce waved his hand, as if he also felt that this passage was unnecessary, "Then the dialysis machine will be turned on, and I will give you the data of the operation in a while." The point is that at the beginning of filtration, the tube of the ultra-permeable membrane has a venous outlet facing upwards, and the filtration flow rate is 100L/. Don't go too high at first. ”

"Wait until the machine has been running for more than two minutes, and then remove the tube from the shelf of the machine and change it to red and blue. Turn off the vein pot when it is almost three-quarters full, and adjust the filtration flow to 200L/. Zhou Ce quickly explained, "Don't ask me why you want to do this, and I don't know." This is required in the instruction manual of the machine. ”

Sun Lien was dumbfounded by this explanation, and opened his mouth for a long time before nodding and saying, "Got it......"

Finally, when the machine is finished, shut it down, and then close the label tube with the clamp that comes with the label tube. Remember to close only the arteries. Zhou Ce said as he directly intercepted the blood report sent by Xiao Guo. After a quick glance, he continued, "After closing the arterial label tube, connect it to the arterial end of the machine with normal saline, adjust the running rate of the machine to 100L/, and shut down the machine when the saline washes the pipes in the machine until it is colorless." The intravenous line is then closed. ”

After this series of sequences, Sun Lien was a little confused. After writing it all, Sun Lien simply re-read the content of his record, and only breathed a sigh of relief after Zhou Ce nodded in approval.

"For DIC patients, who received anticoagulation therapy and then added dialysis anticoagulation, it would be very difficult for her to stop the bleeding afterwards. After extubation, put on the cotton block and tie it with a compression tape for half an hour. Zhou Ce finished the emergency training, and raised the examination report in his hand to Sun Lien, "The blood creatinine concentration is 486μol/L, this patient does need kidney dialysis." ”

"Don't bother. As soon as Zhou Ce's words fell, a woman's voice came from behind him, "I'll just do it." ”

Sun Lien followed the voice and looked at it, his eyes widened. "Why are you here?"

"My boyfriend is going to be quarantined, so I'm going to have to come at this time. Hu Jia didn't wear a white nurse's uniform, and she still had her own clothes on her. Her hair was a little messy, and she looked like she had just taken a shower. "You didn't want to talk to me about such a big thing? If Sister Xu hadn't called me, I wouldn't know what was going on. ”

Hu Jia's expression was very calm, but Sun Lien seemed to feel that the back of his head was a little numb...... It's like the instinctive fear of the rabbit after being targeted by the tiger.

"You go in?" Zhou Ce didn't think Hu Jia's expression had any other meaning, he only turned sideways to block the door of the clean room, and slowly shook his head, "If you can expose one less person, you will have one less risk." You ran in so stunned, isn't it meaningless for Xiao Sun to take the risk?"

"I'm a nurse, and it's my job to help doctors save patients' lives. Hu Jia put on a mask, raised his head and stared at Zhou Ce, "Excuse me." ”

"Sister Hu, calm down. Xiao Guo looked at this scene and only felt that his legs and stomach were about to cramp. He stubbornly moved to the door of the clean room and blocked the door with Zhou Ce. "There's no point in you going in now......"

The two of you persuaded Hu Jia not to mess around, but Hu Jia still stood at the door stubbornly, and it was not easy for anyone to say. The sound in the rescue room gradually became noisy, and finally the noise attracted Liu Tangchun's attention.

Comrade Liu hurried back to the rescue room after learning of the situation, but suddenly calmed down after opening the door. The old man put his hands behind his back and shook his legs, looking like a retired veteran cadre walking comfortably after dinner. Slowly swaying behind Hu Jia, he spoke. But it wasn't against Hu Jia.

"Look at it. Liu Tangchun grinned at Sun Lien, "Did you make trouble for yourself?"

Sun Lien was about to cry, "Teacher Liu, don't make trouble if you don't help...... he waved his hand at Hu Jia, emphatically "I'm really fine!"

"If you don't do it as a good doctor, you have to learn from Zheng Guo's old man. Liu Tangchun smiled, and spoke a little louder, "How many times have I told you, don't worry about finding a girlfriend, it's best not to find a little nurse in our hospital." You know the word "inheritance", right? Xiao Lirong's gang of disciples and grandchildren, all of them are good at it! If you want to squat on the balcony, you have to squat on the balcony, and if you want to eat standing up, you have to stand to eat. ”

Zhou Ce blinked, and suddenly understood what Liu Tangchun wanted to do, so he echoed, "That's it! Our director's wife teaches Chinese in elementary school, so that's what is called gentle and virtuous." ”

"You ...... What do you mean?" Hu Jia, who was calm on the outside but was about to go crazy in his heart, was immediately fooled, "What's wrong with the nurse?"

Zhou Ce and Liu Tangchun exchanged glances with each other, and continued to speak ill of the nurse. The content is rich and colorful, mainly through Zheng Guoguo's tragic life experience, and compared with the director of the nephrology department who has a very successful life after "marrying a female teacher". So as to achieve the purpose of "criticizing Sun Lien for his carelessness in choosing a mate".

The two of them were desperately trying to attract firepower, but the nurses standing next to them had a little bad looks on their faces. Although they also knew that Director Liu and Dr. Zhou had no malicious intent, in this kind of scenario, everyone would inevitably be accidentally injured by stray bullets.

Guo Yulai stood in place, blinking his eyes, but he didn't know which side he should stand on to speak now.
