One by one, they stretched their necks like a flock of geese scrambling to get through the leaded glass to take a closer look. They were counting in their hearts how many items were similar to those used in interventional surgeries in their cardiovascular medicine department, and how many were strange that they had never seen before.
Xie Wanying also looked up and seized the precious opportunity to study hard.
The surgeon took a Y-shaped valve, connected it to a tube, one end was connected to normal saline, and prepared to inject heparin to heparinize the patient's whole body. This is a routine step in many interventional surgeries. Because the tube enters the femoral artery under pressure, not intravenous drip.
, the saline bag that was connected needed to be injected under pressure. The nurse took a pressure bag and put it on the outside of the saline bag, and used an air bag to inflate and pressurize it, instead of squeezing and pressurizing with two hands, which is too laborious and difficult to control the pressure.
The old way.
During the pressurized infusion of fluids, nurses need to keep a close eye to prevent accidents.
Whether it is traditional open surgery or interventional surgery, examinations must be done before treatment, and the lesions must be identified during the operation. Today's patient is even more special. There is no aneurysm in the CT scan report, and the doctor cannot determine whether there is an aneurysm before surgery.
We also don’t know the specific location of the tumor, and we can’t tell whether there are any lesions in the blood vessels in the brain. I told the patient and family members before the operation that whole-brain angiography must be performed first to fully examine the blood vessels in the brain.
See if you can find relevant lesions in this way.
Create shadow agents and take pictures in various positions.
What appears on the monitor screen is the angiographic image of cerebral blood vessels.
The most interesting thing about interventional surgery is this. The angiography of different organs of the human body by different specialized departments can clearly show the different and wonderful blood vessel distribution patterns of each organ. Each has its own characteristics and is unique.
Like the pulmonary angiography mentioned last time, the blood vessels of the lungs are like a lush tree branching left and right. In cardiovascular angiography, the blood vessels are more like a cluster of horizontal branches. The images presented by cerebral angiography are very bizarre.
Each image is a bit like an abstract art painting. It may be two flowers growing on a bare branch, it may be a strange mess of tangled threads, or it may be a few individual branches showing a sense of loneliness.
The cardiologists at the scene were completely silent. They were completely confused and could hardly tell the difference between east, west and north.
The knowledge of different specialties is as separated as a mountain. Even when you are a medical student, you have to read and study it in textbooks and internships. But in the end, if you really want to master the comprehensive knowledge of a specialty, you can't do it in a short internship time. You need to
Clinical practice accumulates over time.
Doctors in the cardiology department cannot infer the cerebral blood vessel distribution from the coronary blood vessel distribution of the heart. The two are completely different and independent knowledge points in anatomy.
The only thing they can confirm now after seeing it with their own eyes is that the distribution of blood vessels in the brain should be much more difficult than that of their heart blood vessels.
The top of surgery, the top of surgery, is not just a random blow. The distribution of cerebral blood vessels is too wide, and the images taken are too fragmented. It is too slow to integrate the three-dimensional mapping by the machine itself, and it can only be the nerve.
The surgeon's mind went crazy on its own.
You can imagine that a doctor who is a neurosurgeon must have the best brain among all doctors.
The operating room is quiet, and the control room is silent.
Neurosurgeons' eyes are like cameras, seriously putting the images into their minds for detailed review and calculation.
