Skin preparation refers to the surgical preparation for shaving and cleaning the body surface at the corresponding part of the operation. It is the work of cleaning the operation area for patients who plan to operate before operation, which is not only as simple as removing body hair, but also includes skin cleaning and sometimes iodophor scrubbing before operation.
The purpose of skin preparation is to reduce the number of postoperative skin bacteria and the infection rate of incision without destroying the integrity of skin.
2 skin preparation principle
1. Do not prepare the skin unless the hair interferes with the operation;
2. If skin preparation is needed, use a special skin preparation device or depilatory;
3. Try to keep the skin intact;
4. Try to get close to the start time of skin preparation.
Skin preparation method
Shaving method
It is a traditional skin preparation method before orthopedic surgery, which is to prepare skin three times in a row and change sterile towel bags three times. Because this method is easy to cause skin damage and bacterial colonization, especially shaving before operation 1 day will increase bacterial colonization and cause discomfort to patients, which greatly increases the workload of nurses.
Chemical depilation
It refers to the effectiveness and superiority of using depilatory emulsion one day before operation instead of wet shaving before operation.
Skin preparation method
Through the upper and lower rows of cutter heads, the row close to the skin does not move, but the upper row moves quickly to achieve the effect of shearing. The guidelines of ARON, CDC and APIC all show that skin preparation with skin preparation device can effectively reduce the possibility of skin injury, thus reducing the infection of surgical incision.
The effects of different skin preparation methods on hair root residue and skin integrity can be observed under the microscope. After using the razor, the hair roots are inclined and the skin may be slightly damaged. However, after using chemical depilatory, the hair is completely removed, and using skin preparation device, the hair roots will remain relatively intact, and the skin can maintain integrity.
