Which phase starts immediately after a surgical incision?

The phase that starts immediately after a surgical incision is the coagulation phase. This initial phase is crucial for preventing excessive blood loss and begins as soon as the tissue is injured. During this phase, the body rapidly responds to the disruption in blood vessels by initiating the clotting process. Platelets aggregate at the site of injury, forming a temporary clot, while various clotting factors activate the coagulation cascade, ultimately leading to the formation of a stable fibrin clot.

This process is essential as it not only seals the wound but also serves as a foundation for later healing stages. Additionally, the coagulation phase lays the groundwork for the subsequent inflammation phase, where cells such as leukocytes migrate to the site to clear debris and pathogens, aiding in further healing. Understanding the coagulation phase is fundamental in post-operative management, as effective hemostasis is critical for a successful recovery.
