Chapter 3497 【3497】Fight to the End

At the critical moment, Xie Wanying gave a vaccination to the teachers who had never done it before: "After being connected to the machine, the first two days may not improve or even look a little worse. After two days, if the machine is effective, the patient will The dependence on machines will gradually decrease.”

Everyone was in a hurry, eager to see the effect of the new machine. Now after hearing her say this, I know that this battle will be fought slowly, and there is no rush.

All the big doctors at the scene can understand that it is never a few hours or a day or two to completely turn the situation around in rescuing a critically ill patient.

During this period, it has become very important to protect patients and find out problems in time and correct them in time. In the future, specially trained nurses will stand by the patient and watch the machine all the way.

At this stage, there are no well-trained nurses, and doctors themselves are not familiar with it. Only the doctor can guard by himself and accumulate experience first.

Director Wang was mentally prepared to move a chair and sit beside the patient's bed and fight to the end.

Director Wang is far from the only one who is ready to fight to the death with the disease.

Zhang Huayao said: "Fix the shift."

After hearing what Chief Zhang said, the others nodded in response: How could it be possible for Director Wang to take advantage of such a good learning opportunity.

Here we are going to talk about Zhang Desheng, who was the first to express his opinion. Suddenly, he found that he was surrounded by people who were competing with him, including the teachers who were scrambling to be the first.

Feng Yicong and the others patted classmate Zhang on the shoulder: Look at you, what's the use of rushing to talk.

The clever student Zhang Desheng ran to find classmate Xie, instead of fighting with the teachers, he could be classmate Xie's little follower obediently.

In the end, it was the teacher who wanted to be a follower with Xie.

I heard Mr. Zhang say: "Mr. Xie, if you tell me how to do it, I will do it."

Several classmates who were about to run to find Xie, screamed in their hearts: Even the big bosses are here to grab the position of follower, what are they going to do now?

I don't care about what Big Boss Zhang said for now, after the ecmo machine is finished, it's the blood filter machine's turn. Xie Wanying and Dr. Liu continued to discuss the key points of crrt technology.

Since CRRT is a type of hemodialysis, its working principle is similar. The purpose of using such a machine is to replace the damaged kidney to perform a kidney-like function, filter out excess water and metabolic waste toxins in the patient's body, and correct water and electrolyte disorders. , to ensure the nutritional support of patients.

From the above description, we can know that this machine is mainly aimed at the patient's body fluid balance. For critically ill patients, rehydration is essential because they cannot eat for a long time and need other anti-inflammatory treatments. In short, you cannot "starve" a patient to death by dehydrating the patient.

At this time, there is a technical difficulty, how to control the amount of various fluids ingested by the patient, to avoid continuous supplementation while treatment, and to prevent the situation that the machine is ineffective or worse.

In addition to routine blood test indicators, monitoring methods are usually used clinically for fluid management, such as the central venous pressure CVP that Xie mentioned earlier. This is a very old and traditional monitoring program.

Medicine is progressing and developing all the time, and CVP has both advantages and limitations.

"CVP can't monitor the preload of the patient's heart, so it can't judge some special situations. In addition, it is affected by many factors during measurement, and the measured value may not be very accurate." Xie Wanying said, "So use PICCO Better."
