Which phase of wound healing involves platelet plug formation for hemostasis?

• A. Early wound healing
• B. Granulation phase
• C. Remodeling phase
• D. Scar maturation phase

Answer: (A)

The phase of wound healing that involves platelet plug formation for hemostasis is known as the early wound healing phase, also referred to as the inflammatory phase. This initial response begins immediately after injury and lasts for several days.

During this phase, when a blood vessel is damaged, platelets adhere to the site of the injury and aggregate to form a plug. This process is crucial for preventing excessive blood loss and is the first step in the healing process. The platelets also release various signaling molecules that recruit other cells to the site of injury, including neutrophils and macrophages, which help in clearing debris and pathogens.

The phases that follow, such as granulation, remodeling, and scar maturation, primarily focus on tissue rebuilding and strengthening rather than the initial hemostatic response. Thus, the early wound healing phase is exclusively characterized by the formation of the platelet plug to achieve hemostasis.
