This is not enough. According to the patient's imaging examination, the most fluid accumulation may be near the liver. In other words, the puncture must be done from the eleventh intercostal space. The fluid must be drawn from the place with the most fluid accumulation, otherwise it will be useless.
"Tell me the depth of the needle." Xin Yanjun whispered to the student.
It is not that this place cannot be drained. The most important thing is that the doctor must be fully aware of the location of the patient's internal organs in this place. The liver is here, but the liver 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 it will be inserted into the fat layer and the pleural effusion cannot be drained. After all, this patient is fat, which makes the doctor's operation too difficult.
The nurse who was listening to their conversation nearby was concentrating so much that she didn't notice someone coming to the ward door.
Xin Yanjun and Xie Wanying were so focused on the patient who needed water removed that it was impossible for them to pay attention to the situation around them.
The two people who came in from the ward door were quite swaggering. Seeing that no one in the room was aware of their presence, the two men did not tell anyone of their presence for some unknown purpose.
Just like what Song Xuelin commented before, the predecessors of the National Association are more cunning than Beidu, and like to be invisible knights who come and go without a trace.
The two male doctors passed by the nurses and went behind Xie Wanying and Xin Yanjun, hiding in a secluded corner, silently watching how the two female doctors were going to pump the water.
"Teacher Xin, the depth needs to be about 7 centimeters." Xie Wanying told the teacher her estimated results.
...
...
After hearing her words, Xin Yanjun had a certain idea in her mind and injected the local anesthetic needle into the area designated by Xie Wanying's hand, which was the eleventh intercostal space.
The two male doctors saw this and one of them whispered in the other's ear: "Doctor Li, who is directing whom?"
Hearing this, the male doctor, Dr. Li, whose name was Li Chengyuan on the doctor's badge on his chest, raised his knife-thin eyebrows as if he was raising Mount Everest. The sharpness in his narrowed eyes flashed across Xie Wanying's masked face.
If she hadn't been here, there would never have been such a weird scene. There was a hint of this in Li Chengyuan's eyes.
After the anesthesia, the patient felt no pain, and the disinfected sheet was laid. Xin Yanjun took the puncture needle and pierced the skin. The connected syringe was carefully withdrawn while the needle was inserted. If blood was drawn out, the needle must be stopped immediately.
The most feared thing when inserting a needle into the intercostal space is puncturing the intercostal artery.
Following the teacher's every move with her eyes, Xie Wanying's hand suddenly rested on Teacher Xin's operating arm.
Xin Yanjun immediately understood that she was helping her fine-tune the angle, so she relaxed her tense arm muscles and let her hold her arms tightly to make adjustments.
Needle, in, in again.
The people watching around were a little nervous.
The patient's skin (fat) is too thick. 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 terrifying thing is that in such thick flesh, the arteries and veins inside are probably full of blood flow. If the small needle hits the blood vessel by mistake, it will detonate a landmine. You can imagine it as an ant shaking an elephant.
The puncture needle is like a small boat, moving forward carefully avoiding all dangers in the deep sea full of reefs to reach its destination.
