Transcutaneous is an adjective that describes something that takes place or is administered through or by way of the skin. The term is derived from the Latin words "trans," meaning "across" or "through," and "cutis," meaning "skin." When something is transcutaneous, it means it is able to penetrate the skin barrier to achieve its intended effect.
In the medical field, transcutaneous procedures or therapies involve the introduction of substances or medications through the skin for various purposes. This can include the delivery of drugs or therapeutic agents, such as patches or creams that release medication slowly over time, or the use of electrical stimulation through the skin to treat pain or stimulate nerve activity.
Transcutaneous procedures can also refer to diagnostic tests or monitoring techniques that involve accessing information or measurements through the skin. Examples of this include transcutaneous oxygen saturation (measuring oxygen levels in the blood through the skin) or transcutaneous electrical nerve stimulation (TENS), which is a process wherein low-voltage electrical currents are applied to the skin surface to provide pain relief.
In summary, the term transcutaneous pertains to processes, treatments, or tests that occur through the skin, showcasing the ability of a substance, technique, or diagnostic method to traverse the skin barrier in order to achieve a desired therapeutic effect.
The word transcutaneous derives from the combination of two Latin roots: trans-, meaning across or through, and cutis, meaning skin. Therefore, the etymology of transcutaneous can be understood as through the skin or across the skin.
