Press the above-mentioned position with the middle finger of your left hand, hold the needle with your right hand, and remember to insert the needle at an angle of 15 to 30 degrees along the direction of the blood vessel. The best insertion point is at one-third of the line connecting the midpoints of the patient's mandible and the upper edge of the clavicle.
That's what the textbook says, but it's a great test of the eyesight of the person giving the injection. Those who don't have much eyesight can rely on experience. Xie Wanying was doing this kind of external jugular vein puncture for the first time, and she could only think that it should be much easier than the subclavian vein, at least it's a blood vessel that can be seen and touched. So she had the courage to try it, and there were two old nurses and Teacher Ren around her.
Her eyes were focused on the estimated puncture point. She held the puncture needle and inserted it parallel to the angle she had designed. She had to insert it quickly to reduce the patient's pain. After entering the blood vessel and seeing that the blood was returning correctly, she had to move gently and steadily, and withdraw the steel needle in time, leaving the hose behind. The assistant old nurse hurriedly helped her apply the dressing and fix the needle wing, drew some blood with a syringe and sent it for testing, and then hung up the saline solution. This was equivalent to establishing a supply channel to maintain the patient's lifeline, which allowed everyone to calm down a little.
The experienced nurses didn't know that it was her first time to do the puncture and said, "We can tell at a glance that you are an expert at giving injections." They seemed to have forgotten that Xie Wanying had just said that she was just a student.
On Dongzi's side, Ren Chongda called his old classmate Cao Yong.
Neurosurgery operations take a long time. Cao Yong had just come off the operating table at 1:00 p.m. Huang Zhilei and other assistants were still on the operating table, finishing up the work. Cao Yong walked out of the operating room first and received a call for help from Ren Chongda.
"What's going on?" Cao Yong asked.
"A boy of about five years old has acute brain hernia. His pupils first shrank and are now dilating. I'm worried that he won't survive if he doesn't have drainage," said Ren Chongda.
"Which hospital are you in? Are you in our emergency department?"
...
...
"Definitely not! We asked you to come down directly from our hospital."
"So which hospital are you in now?"
"Outpatient building. We met a patient from a car accident on the road. The ambulance took a long time to come. Maybe the road was blocked. We moved the patient to a nearby outpatient building first. There should be something here that can be used."
"You didn't take the CT scan, did you?"
"No, the person is unconscious."
"You are not me. Do you think you dare to do it without CT scan?"
The soul-searching question from his old classmate made Ren Chongda touch his forehead. His palms were covered with sweat. It could be anxiety, or it could be fear and terror. The patient's life or death was in his hands at this moment. It was just that he hadn't been a clinical doctor for a long time. He was afraid that his skills had become rusty, which made him feel uneasy.
Not hearing any response from his old classmate, Cao Yong thought to himself, if it was the junior sister, she would definitely answer him immediately: Try, try no matter what, you have to try for the patient's life!
Junior sister Yingying was the first rookie he had ever seen who was fearless and brave, and this made all the teachers and seniors always worried about her. Her practice of always going all out was rare in the medical circle. It was rare, but not uncommon. It wasn't that doctors didn't want to do this, but most doctors didn't have the technical strength to do so.
Indeed, if you don’t try, the patient will die. In this case, can the doctor choose not to do it because of the difficulty of practical operation, just to avoid his own risks and then shirk his responsibility?
