In the outpatient clinic, doctors wear white coats, but when they enter the operating room, the surgeon usually puts on a green or blue surgical gown.
Do you know why? Today I will take you to explore the truth of this fact!
It is said that before 1914, all medical staff were uniformly wearing white uniforms, just like the white coats of doctors we usually see in hospitals.
However, during the First World War, many battlefield military doctors reported the same problem to their superiors: when they turned their sights from crimson blood to white doctor uniforms during a long operation, they would be temporarily unable to The transient blindness in which Qing Qing can not even see things has caused many accidents in surgery.
After a period of research, it turns out that this is caused by the phenomenon of "complementary color afterimage", that is, when people always stare at one color, and then look at other places, in order to obtain their own balance, the eyes have to produce A complementary color is used as a modifier, for example, red to green, blue to orange, and yellow to purple.
Because surgeons must race against time and focus when performing operations, they will keep their eyes on the red internal organs. If they look at their colleagues in white clothes at this time, or glance at the white walls, they will often see blue-green "ghosts".
These blue-green afterimages will affect the surgeon's vision and judgment, which is very dangerous for the patient. Although they only last a few seconds and seem to be short and will not affect people, they can be fatal during surgery.
So later, surgeons chose to wear blue and green surgical gowns to relieve visual pressure. At the same time, the operating room was basically green.
In addition, it is easy to get red blood stains in the surgical environment. If you wear a "white coat", the blood stains on your clothes will cause a bloody visual impact. Wearing green and blue uniforms will turn black and brown even if blood stains on the clothes, thus playing a role in visual adjustment.
In addition, blue or green surgical gowns will not produce marks during repeated disinfection and sterilization, which has become a habit similar to the convention in the medical industry.
Finally, during the operation, the surgeon is often under tremendous pressure. At this time, the green of the surgical gown can give people an impression of being full of vitality and give doctors a good psychological hint.
Therefore, surgical gowns and surgical appliances are basically green or blue now. Now, have you figured it out?
