During which phase of graft take does the graft appear pink in color?

The graft appearing pink in color is characteristic of the inosculation stage. During this phase, the newly transplanted graft undergoes successful integration with the surrounding host tissue. Vessels from both the graft and the host tissue begin to connect, leading to improved perfusion and subsequently a pink hue that indicates adequate blood flow.

This visual change is a positive sign of the graft's acceptance and suggests that the body is starting to receive the nutrients and circulating blood necessary for the graft’s survival. Inosculation is essential for the graft to become functional and to promote healing in the areas affected by burns.

In contrast, other options describe different processes that do not specifically correspond to the pink coloration associated with successful graft take. The imbibition stage focuses on the initial absorption of fluid by the graft, and during this time, it may not yet appear pink. The revascularization stage involves a further development of vascular connections but may not present the stable integration indicated by the pink color. The detachment phase generally refers to a phase where graft rejection might occur, resulting in a more distressed or pale appearance rather than pink.
