When a skin graft is not immediately used after being harvested, what is the proper method to maintain it?

The best method to maintain a skin graft when it is not used immediately after harvesting is to spread it on a convex surface of a metal basin that is continuously moistened with saline or an antibiotic solution. This approach helps to preserve the viability of the graft by ensuring that it remains hydrated, which is crucial for its cells to stay alive and functional.

Keeping the graft moist prevents drying out, which can lead to cellular death and compromise the graft's chances of successfully integrating with the recipient site later on. The convex shape of the basin helps to provide a consistent surface for the graft, reducing the risk of damage during storage.

Other methods, such as simply wrapping the graft in gauze, do not provide adequate moisture and can lead to desiccation. Storing it at room temperature can also result in deterioration of the graft, while refrigeration may slow down metabolic processes but is not ideal for the living tissue of a skin graft, potentially leading to changes in its viability.

Overall, maintaining appropriate hydration and a suitable storage environment is key to preserving the integrity of harvested skin grafts before they are used in surgical procedures.
