Hold the above-mentioned position with the middle finger of your left hand firmly, and hold the needle in your right hand. Remember to insert the needle at an angle of 15 to 30 degrees along the direction of the blood vessel. The best choice for the needle insertion point is the line connecting the midpoint of the patient's mandible and the upper edge of the clavicle. One point.
This is what the textbook says, but it greatly tests the eyesight of the person giving the injection. Those who don’t have much vision can rely on experience. This is the first time for Xie Wanying to puncture this kind of external jugular vein. She can only think that it should be much easier than the subclavian vein, at least it is a blood vessel that can be seen and touched. This gave her the courage to try, and there were two old nurse teachers and Teacher Ren around.
Her eyes were focused on the estimated puncture point. The hand-held puncture needle was inserted parallel to the angle she designed. The needle should be inserted quickly into the skin to reduce the patient's pain. After entering the blood vessel and seeing that the blood returns is correct, the movement should be gentle and steady, and the steel needle should be withdrawn in time to leave the hose. The auxiliary old nurse hurriedly helped her apply a dressing and fix the needle wing, drew some blood with a syringe, sent it for testing, and then hung up the normal saline. This is equivalent to the establishment of a supply channel that maintains the patient's lifeline, allowing everyone to calm down a little first.
Regarding her successful puncture, the old nurses didn't know that it was her first time, and said, "I can tell at a glance that you are a veteran of injections." It was as if they had 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 takes a long time. It was one o'clock in the afternoon when Cao Yong got off the operating table. Huang Zhilei and other assistants did not step off the stage, but were doing finishing work on the operating table. Cao Yong walked out of the operation first and accepted the call for help from Chongda.
"What's going on?" Cao Yong asked.
"In an acute cerebral herniation, in a boy about five years old, the pupils shrank at first and are now likely to expand. I'm worried that he won't be able to survive without drainage," said Ren Chongda.
"Which hospital are you in? Are you in emergency in our hospital?"
"Definitely not! We asked you to come down directly from our hospital."
"So which hospital are you in now?"
"Outpatient building. A car accident patient encountered on the road. The ambulance didn't come for a long time, maybe the road was blocked. We moved the patient to a nearby outpatient building first. There should be something we can use here."
"You didn't take the CT scan?"
"No, the person is unconscious."
"You are not me. Do you think you dare to attack me without taking CT scan?"
The old classmate's soul questioning made Ren Chongda touch his forehead with his hand. His palms were covered with beads of sweat. It may be anxiety, or it may be fear and fear. The patient's life or death is in the palm of his hand at this moment. It's just that he hasn't been a clinician for a long time, and he hasn't been exposed to clinical practice for a long time. He is afraid that his skills are rusty, which makes him feel uneasy.
Not hearing the response from his old classmate opposite, Cao Yong thought to himself that if it was a junior sister, she would definitely answer him right now: Try, no matter what, you must try for the life of the patient!
Junior sister Yingying is the first rookie he has ever seen who is not afraid of tigers even after giving birth to calves. Because of this, all the teachers and seniors are always worried about her. Her approach of always going all out is rare in the medical circle. Rare, but not impossible. It’s not that doctors don’t want to do this, but that most doctors don’t have the technical capabilities.
Indeed, if you don’t try, the patient will die. In this case, can the doctor choose not to do it because the actual operation is difficult, just to avoid his own risks and thus shirk his responsibility?
