Crepitus is best described as an accumulation of air or gas in the tissues. This phenomenon occurs when air escapes from the lungs or gastrointestinal tract into the subcutaneous tissue, often as a result of an injury or surgery that disrupts the integrity of tissues. It is characterized by a palpable or audible crackling sensation when the affected area is palpated, which can be associated with certain conditions, such as gas gangrene or pneumothorax. The presence of crepitus is significant in wound care as it can indicate underlying complications, such as infection or tissue injury, that need to be addressed. Recognizing crepitus in a clinical setting is vital for prompt diagnosis and management of potential issues related to air or gas accumulation.
