What does infiltration refer to in the context of wound healing?

Infiltration in the context of wound healing specifically refers to the accumulation of fluid in the interstitial tissue, which can lead to swelling in the affected area. This fluid accumulation typically occurs due to various physiological responses to injury, such as inflammation, where plasma and other fluids leak into the surrounding tissues. This process is part of the body's healing response, as it helps to deliver nutrients and immune cells to the site of injury.

The presence of swelling can indicate increased permeability of the blood vessels, which is a common reaction to tissue damage. While this process can be beneficial in the initial stages of healing as it promotes the delivery of necessary components to the wound, excessive infiltration can lead to complications, including delayed healing or further tissue damage. Understanding infiltration and its implications is crucial in managing wound healing effectively, as appropriate interventions may be required to address excessive fluid accumulation.
