To what extent should the skin be shaved?

Skin preparation is usually done 15-20 cm outside the surgical incision.

If skin preparation is done before surgery, it is recommended to perform skin preparation close to the surgical incision site, generally 15-20 cm outside the surgical incision site. It helps to reduce the number of local pathogens and fully expose the surgical site, which helps doctors to operate and helps reduce the risk of secondary infection after surgery.

Patients should pay attention to keeping the incision site clean and dry after surgery. Do not scratch the affected area with dirty hands at will, otherwise it will cause local skin and mucous membrane damage. It may also induce secondary infection, local swelling, pain and other discomfort symptoms.
