At the critical moment, Xie Wanying gave another vaccination to the teachers who had never done it before: "After being put on the machine, there may not be any improvement in the first two days or even seem to be a little worse. After two days, if the machine is effective, the patient will
The dependence on machines will gradually decrease."
Everyone was originally very anxious, eager to see the effects of the new machine. Now after hearing her words, it became clear that this battle must be fought slowly and there was no need to rush.
All the doctors and experts at the scene can understand that rescuing a critically ill patient can never completely reverse the situation in a few hours or a day or two.
During this period, it has become very important to protect the patient and detect problems in time and correct them in time. In the future, specially trained nurses will stay beside 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. They can only take care of themselves and gain experience first.
Director Wang was mentally prepared to move a chair and sit next to the patient's bed and fight to the end.
Director Wang is far from the only one who is prepared to fight the disease to the death.
Zhang Huayao said: "Arrange your classes."
After hearing what Leader Zhang said, everyone else nodded in response: How could Director Wang take advantage of such a good learning opportunity alone?
Here we have to talk about Zhang Desheng, who was the first to express his stance. Suddenly, he found that he was surrounded by people competing for opportunities with him, including teachers who were scrambling to be the first.
Feng Yicong and others patted classmate Zhang on the shoulder: Look, what's the use of rushing to say it.
The smart classmate Zhang Desheng ran to find classmate Xie. Instead of competing with the teachers, he could be a good follower of classmate Xie.
As a result, all the teachers wanted to be classmates with Xie.
I heard Mr. Zhang say: "Teacher Xie, you tell me what to do, and I will do it."
They all wanted to run to find Xie's classmates, screaming from the bottom of their hearts: Even the bosses are coming to compete for the position of the follower, what are they going to do now?
I couldn't care about what Mr. Zhang said for the moment. After putting on the ECMO machine, it was the turn of the hemofiltration machine. 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 kidneys and perform kidney-like functions, filter out excess water and metabolic waste toxins in the patient's body, and correct water and electrolyte disorders.
, ensure nutritional support for patients.
From the above description, we can know that the main purpose of this machine after it is installed is the patient's fluid balance. For critically ill patients, since they cannot eat for a long time and require other anti-inflammatory treatments, rehydration is essential. Briefly speaking,
, you cannot "starve" a patient to death by dehydrating him or her.
At this time, there is a technical difficulty, how to control the patient's various fluid infusion volumes, to avoid continuing to supplement randomly during treatment, and to prevent the machine from being ineffective or worse.
In addition to conventional blood test indicators, monitoring methods are usually used clinically for fluid management, such as the central venous pressure (CVP) that Xie mentioned before. This is a very old and traditional monitoring plan.
Medicine is progressing and developing all the time, and CVP has advantages but also limitations.
"CVP cannot monitor the preload of the patient's heart, so it cannot judge some special circumstances. In addition, it is affected by many factors when measuring, and the measured value may not be very accurate." Xie Wanying said, "So PICCO is used.
