2、 Can gauze bandage directly contact the wound
The key use of gauze bandage is to bind the wound area, which has the effect of compression and hemostasis. Generally, gauze is sterilized and can be used directly in the wound. Bandage is mainly used to fix or protect the material of the operation or injury area. Because the bandage is not sterilized, it can not be used directly in the wound area, but can be used to bind gauze. We can disinfect the injured area first, then cover the wound area with gauze, then bandage and fix it with bandage, and then tie and fix it. The bandage can also be used for bandage of trauma, varicose veins, orthopedics and other diseases.
In clinical practice, the medical gauze and bandage can directly contact the wound area, and almost all of them are subject to strict sterilization treatment. Patients need not worry about it, and there will be basically no infection or inflammation.
Here, Xiao Bian suggests that before using gauze or bandage to bandage the wound, clean the wound well. If there are impurities or some necrotic tissue, clean the wound first, and then do a good job of disinfection and anti-infection treatment, so as to prevent the progress of healing around the recovery period.
In normal life, you can see that the gauze bandage can be directly used in wound dressing if it is sterilized. If it is not, it can only be used in the wound area after sterilization!
