This is not enough. According to the patient's condition, it can be deduced from the impact study that the place with the most fluid accumulation may be near the liver. In other words, puncture needs to be done from the 11th intercostal space. The fluid must be extracted from the place with the most fluid accumulation, otherwise it will be useless.
.
"Tell me the depth of the needle insertion." Xin Yanjun communicated with the student in a low voice.
This area is not unavoidable. The most important thing is that the doctor must know the location of the patient's internal organs. The liver is here, but it is near the lungs. As long as the depth of the needle does not touch the liver, it will not cause liver bleeding.
At the same time, the depth of the needle must be sufficient, otherwise the pleural effusion cannot be extracted if it is inserted into the fat layer. After all, the patient is fat, which makes the doctor's operation too difficult.
The nurse who was listening to the two of them was so focused that she didn't notice anyone coming to the door of the ward.
Xin Yanjun and Xie Wanying were focused on the patients who needed to be pumped, and it was impossible for them to pay attention to their surroundings.
The two people who came in from the door of the ward were quite arrogant, and no one in the room noticed their arrival. For some unknown reason, these two people did not tell anyone that they were coming.
Just like what Song Xuelin said before, the seniors of the National Association are more sneaky than those in Beidu, and they like to be shadowless warriors who come and go without a trace.
The two male doctors passed by the nurse and went behind Xie Wanying, Xin Yanjun and the others. They seemed to be hiding in a hidden corner, silently watching how the two female doctors were going to pump water.
"Teacher Xin, the depth should be about 7 centimeters." Xie Wanying told the teacher her calculations.
After listening to her words, Xin Yanjun had a certain idea in her mind and injected the local anesthetic needle into the designated part of Xie Wanying's hand, that is, the eleventh intercostal space.
When two male doctors saw this, one of them spoke into the ear of the other: "Dr. Li, who do you think is instructing whom?"
The male doctor who heard this, Dr. Li, had a doctor's sign hanging on his chest with the name Li Chengyuan written on it. His eyebrows were raised as thin as a knife, as if he were raising a Mount Everest.
The sharpness in her eyes reflected on Xie Wanying's masked face.
It is estimated that if she were not here, such a weird scene would never have happened. If there was such a look in Li Chengyuan's eyes.
After the anesthesia was administered, the patient felt no pain, and the drapes were sterilized. Xin Yanjun took the puncture needle and inserted it into the skin. The connected syringe was carefully withdrawn while inserting the needle. If blood was drawn out, the injection must be stopped immediately.
The biggest fear when inserting a needle into the intercostal space is that it will pierce the intercostal artery.
With her eyes following every move of the teacher's hands, Xie Wanying's hand suddenly rested on Teacher Xin's arm.
Xin Yanjun immediately understood that she was helping her fine-tune the angle, so she relaxed her tight arm muscles and asked her to hold her arm tightly to adjust it.
Needle, go in, go in again.
The people watching around were a little sweaty.
The patient's skin (fat) is too thick, and the thick pile of flesh makes the thicker puncture needle look like a small ant about to be submerged in the sea of flesh. The most frightening thing is that inside such thick flesh, there are
The arteries and veins are probably full of blood. If a small needle is inserted and accidentally hits a blood vessel, a nuclear warhead will be detonated. You can imagine that an ant shakes an elephant.
The puncture needle is like a small boat, carefully avoiding all dangers in the deep sea surrounded by reefs to reach its destination.
