Some people don't know the difference between an operating coat and a hand-washing coat, and don't understand why there is an operating coat and a hand-washing coat. So what's the main difference between an operating suit and a hand-washing suit?

The operating room is a magical and sacred place, orderly and isolated from germs. To do this, it is inseparable from a very strict system. Doctors have to wear an operating coat and wash their hands to disinfect them.

The operating room coveralls are different from the common nurse coveralls. The formal stage is a long-sleeved gown with a small high collar, opening at the back and worn with the assistance of a nurse. This is called an operating coat. The color is mostly light blue or light green. The clean area shall be deemed as the internal contact of the operating garment with the body of the doctor, and the contaminated area shall be deemed as the external contact with blood and body fluids and the patient. The operating clothes must be completely isolated from the polluted and clean environment, so they are tightly wrapped.

Usually v-neck and short-sleeved, the official name is hand-washing. It's the uniform that the operating room staff use in the clean environment of the operating room, whether it's a doctor or a nurse or an anesthesiologist. Once in the operating room, the uniform must be changed. The short sleeves are designed to make it easier for surgical personnel to clean the hands, forearms and first third of the upper arm. After the surgical personnel wash their hands, the nurses assist to put on the operating clothes. Some prefer to use color to distinguish different workers. In Japan, for example, anesthesiologists usually wear dark red hand-washing clothes. At home, it's green.

The operating room also has a kind of clothes, called visiting clothes, used for the outside personnel to enter the operating room to visit when wearing.

In addition to the operating room and some specific departments, the rest of the nurses' uniform is the white dress you say, all styles and colors are not all the same, but the world is basically universal. The other thing is that summer dresses will be replaced by short sleeves.
