When you are in the operating room, you will find that the doctor will cover the patient with a lot of surgical drapes during the operation, and in the end only a small operation area will be exposed. The shape is different, it may be round or square. In fact, this is mainly due to the following reasons:

1. Aseptic requirements

If there is no aseptic operation, the mortality rate of the operation is very high. In addition to killing most of the microorganisms on the skin surface through skin disinfection, the operation also has to spread various surgical drapes to isolate the remaining bacteria in the air and on the body to prevent the occurrence of surgical infections.

2. Keep warm

The temperature of the operating room is generally controlled at about 25℃. After surgery and anesthesia, especially general anesthesia, the patients metabolism will be reduced by the anesthetic drugs, so the heat production will be reduced. In addition, Surgery may not avoid opening the body and infusion is needed to maintain the internal environment, which will result in a relatively low body temperature. Spreading the surgical drape can play a role in keeping warm to a certain extent.

3. Protect patient privacy

During the operation, in order to be sterile, in many cases there is no clothing attached to the operation area or even the whole body. After the doctor disinfects the patient, the rest of the area is covered with surgical drape. As long as the operation field is exposed, it is convenient for the doctor to operate. This can well protect the patients privacy.
