In wound care, why should hydrogen peroxide and alcohol be avoided prior to suturing?

Hydrogen peroxide and alcohol should be avoided prior to suturing because they can cause tissue damage. Both substances are known for their antiseptic properties; however, they are quite harsh on healthy tissue. When applied to wounds, these agents can harm the cells that are critical for healing, such as fibroblasts and keratinocytes. This tissue damage can impair healing and increase the risk of infection by disrupting the natural barriers of the skin and surrounding tissues.

In contrast, while some antiseptics may be less damaging or more effective for specific situations, the focus here is on the detrimental effects that hydrogen peroxide and alcohol can have on viable tissue when preparing a wound for suturing. This understanding emphasizes the importance of using appropriate wound care practices that promote optimal healing conditions.
