Wet healing theory refers to the study by British zoologist Dr. Winter in 1962 found that in a moderately wet environment, the wound healing speed is more than twice as fast as that in a completely dry environment. This theory emphasizes the importance of keeping wounds moist to promote cell regeneration and migration, speeding up the wound healing process.
Specific meaning:
1.Enhanced cell regeneration: In a moist environment, epidermal cells at the wound site move faster, thus accelerating wound healing.
2.Capillary formation: Maintaining the hypoxic state of the wound local microenvironment is conducive to promoting capillary growth.
3.Necrotic tissue lysis: Moist environment facilitates the dissolution of fibrin and necrotic tissue, reducing the risk of infection.
4.Release of active substances: The active substances in the exudate are retained and effectively utilized in a humid environment.
5.Reduce pain and infection: Keeping the wound moist reduces pain and prevents dry scabs from forming, thereby reducing the chance of infection.
6.Granulation tissue growth: Suitable humidity conditions promote the formation of granulation tissue and accelerate the wound healing process.
Extension and expansion:
1.Dressing selection: The ideal wound dressing should control water evaporation, keep the wound moist, absorb excessive seepage, protect the wound from microbial invasion, while not affecting the normal wound healing mechanism.
2.Clinical application: Wet healing theory has been widely used in chronic wound care, such as diabetic foot ulcers, pressure sores, etc., significantly improving the treatment effect and quality of life of patients.
Note: Although wet healing is beneficial for wound healing, excessive wetting can also lead to an increased risk of infection, so it is necessary to choose the right dressing and treatment for the specific wound.
