    As mentioned before, you cannot choose the internal jugular vein. If you are in vvecmo mode, you may have to choose the left and right veins.  In vaecmo mode, you can choose the femoral artery or femoral vein on one side for puncture.

    Arteriovenous puncture is risky.

    In order to ensure the success rate of puncture, imaging machines are used to assist in interventional operating rooms.

    ??What would you do if you don¡¯t have an imaging machine for a bedside puncture like this?

    Xie Wanying suggested to the teacher: "Use ultrasound equipment to help. It can choose to detect the diameter of the patient's blood vessels, allowing the doctor to better choose which blood vessel to puncture and position."

    The teachers listened to her suggestion and considered it first.  It is a bit troublesome to bring the ultrasound machine to the bedside, which makes people need to think about whether it is necessary.  It stands to reason that there are many doctors in Guozhi who are familiar with doing this kind of puncture, so it is not necessarily necessary to use machines to assist their doctors in doing this.

    Blood vessel positioning.  In this regard, Xie Wanying raised another technical question: "If femoral artery puncture is performed, the blood supply to the distal lower limbs needs to be ensured. Once there is a situation, with the regular detection of ultrasound equipment, the problem can be found in time and the lower limbs can be repaired.

    Distal arterial closure perfusion avoids complications.  "

    After hearing what she said, Zhang Huayao, who took the initiative to change the mode, had to raise his head and look at her, his eyes were about to explode with shock.  It can be seen that he really didn't consider this issue.

    ¡°Don¡¯t blame him, even if he is a big boss, he has never used a machine and is not familiar with all possible clinical complications.  Since Teacher Zhang wants to switch to vaecmo mode, Xie Wanying must make some suggestions: "The membrane lungs and pumps used in vaecmo mode and vvecmo mode can be used slightly if the need to move the patient in emergency is eliminated.

    ??????????????????? The vaecmo mode involves cardiac assistance, preferably using a centrifugal pump and a hollow fiber membrane lung.  For simple breathing assistance, roller pumps and silicone membrane lungs can be used.  "

    This time it was Director Wang¡¯s turn to listen to her words and quickly turn around to recheck whether the machine was installed correctly.  He didn't seem to see these in the manual.  Director Wang touched his body and took out his notebook to take notes.

    The doctors around them were silent for a long time. They saw the two leaders being instructed repeatedly by the stubborn Teacher Xie. This scene left people completely speechless.

    "It's all up to you." Zhang Huayao waved his hand cheerfully and gave instructions.

    It can be seen that the boss really doesn¡¯t mind having many mistakes pointed out by Teacher Xie.

    Shen Youhuan quickly called the ultrasound department to send the machine, because he or Ye Qing should do the puncture later.  In fact, having an ultrasound machine has various other benefits. For example, the punctured femoral vein tube needs to reach the junction of the right atrium and the inferior vena cava, and the length reaches 40 to 55 centimeters.  If there is an ultrasound machine using a probe, you can

    So that you can know more accurately whether it is inserted in place.

    The machines are put in place one after another.

    The sonographer brought over the ultrasound machine.  The nephrologist brought over a hemofiltration machine.

    After Dr. Liu from the Department of Nephrology arrived at the scene, he confessed to Mr. Zhang: ¡°I have never done it before and I don¡¯t know how to do it. I didn¡¯t even know that our hospital had an ecmo machine before.¡±

    Brother Zhang pointed his hand at Teacher Xie opposite: "You can ask her."

    "Where did she come from as a teacher?" Dr. Liu asked the same question as Director Wang, who was the young boss in front of him.

    If it weren¡¯t for the fact that Boss Zhang stared at her and refused to say anything, Xie Wanying would have wanted to reveal that she was not a teacher.

    "You first listen to what she said." Boss Zhang said.  It doesn¡¯t matter what your identity is. What matters is that you can save people by asking for technical information to help you.  (Remember the website address: www.hlnovel.com
