    "No wonder that orthopedics is a gathering place for strong men and strong women. All these tasks require full strength.

    ?????????????????????????????????????????????????????????????????¡­??????????????????????????????????????????????????????????????????????????????????????? The seniors are so suave and Dr. Liu is so gentle. Who would have thought that they snap and break bones during orthopedic surgery, like Popeye who ate spinach.

    Speaking of extracardiac surgery, if thoracoscopy had not been developed, traditional surgery would have also required breaking bones.  For this reason, Xie Wanying looked at the rib cutter and thought a lot about trying it.  It was impossible for the teacher to give her this opportunity when she first came on stage. She could only observe how the seniors used tools to convey power to quickly achieve their goals today, and then study it on her own when she went back to ensure that she would not miss it next time she had the opportunity.

    After cleaning the connecting tissues around the diseased thoracic vertebrae, the next step is to remove the entire diseased thoracic vertebrae from the human body. This is the first critical step in the entire operation.  In the imagination of outsiders, if the connecting things around the thoracic vertebrae are removed, this thing can naturally be pulled out, so there is no need for anything else.

    This is a misconception based on ignorance of human anatomy.

    There is a vertebral foramen in the middle of the thoracic vertebrae, and the vertebral foramina is connected to form the spinal canal. Walking in the spinal canal is the central nervous system that controls the trunk and limbs: the spinal cord.

    It is self-evident how important the spinal cord is to the human body.  It can be said that without the spinal cord, the execution effect of the signals sent by the brain to the body is zero, and the signals cannot be conveyed.

    If you want to separate the vertebrae from the spinal cord without damaging the spinal cord, there is no other way but to cut the vertebrae in half and cut open the spinal cord.  The vertebral foramen and the spinal cord are closely connected, especially since this is a diseased vertebra. The tumor has established a connection between the vertebrae and the spinal cord. All of this makes it very easy to accidentally injure the spinal cord.  How to ensure that bone cutting does not inadvertently injure the central nervous system?  If you can't see clearly with your eyes, you can only rely on monitoring methods like fire alarms.  If there is any sign of injury, the police will be called immediately, and the doctor will stop the operation and avoid the alarm area.  In spine surgery, such fire alarm monitoring is called neuroelectrophysiological testing.  There are three commonly used ones: SEP, which monitors ascending sensory nerve conduction, commonly known as somatosensory evoked potential; MEP, which monitors descending motor nerve conduction, is motor evoked potential; and EMG, which monitors the nerves that control muscle activity.

    The three monitoring projects each have their own advantages and disadvantages. If possible, they should use their strengths and avoid weaknesses to form complementary advantages. The more data doctors have, the more they can fully implement intraoperative monitoring and make their surgical activities accurate enough to avoid accidental injuries.

    The monitoring is all on. The main surgeon is busy cutting and has no time to look at the monitoring screen immediately. The assistant should be responsible for reminding the main surgeon in time.  At the scene, Dr. Liu quickly taught the students how to observe the data, so that they could start to help as soon as possible.

    "Simply speaking, these monitoring items are similar to other monitoring items. A rough judgment can be made by looking at the waveform. Large changes in the waveform definitely indicate that the situation is abnormal." Dr. Liu said.

    This is the significance of mankind¡¯s invention of waveform charts. The undulating curve allows the human eye to quickly and intuitively judge abnormal changes in data, without the need for the human eye to carefully identify the changes in numbers one by one.

    The only disadvantage is that waveform diagrams can generally only represent one kind of data change. If you encounter complex situations and need to combine other data for comprehensive judgment, human brain estimation is essential.  Therefore, the doctor who is looking at the instrument has his brain working all the time, and it is not as easy as others think.  This is most often reflected in the complaints of anesthetists.  (Remember the website address: www.hlnovel.com
