Which statement is true pertaining to the use of plain catgut sutures?

Plain catgut sutures are indeed classified as absorbable sutures, meaning that they are designed to be broken down and absorbed by the body over time. This characteristic makes them particularly useful for internal suturing where the material does not need to be removed after healing; the body gradually dissolves the sutures as it heals.

In contrast, some sutures are considered non-absorbable, which means they must be physically removed after a certain period, and these are often used on the skin or in situations where long-term support is required. Special handling is generally not a requirement for plain catgut, unlike other more specialized materials that may necessitate particular techniques or considerations. Lastly, while plain catgut can be used for many types of wounds, it is not suitable for all, such as in cases that require prolonged strength or where infection risks are higher. Thus, the distinctive aspect of plain catgut sutures being absorbable highlights their specific function and benefits in surgical procedures.
