Final answer:
Retention sutures can be used in various types of incisions such as vertical midline, McBurney, transverse, and thoracoabdominal to provide added wound support, especially in abdominal surgeries.
Step-by-step explanation:
Retention sutures may be used in instances where there is a need for increased wound support during healing, usually in cases where there is a high tension on the wound or in patients who are at risk for wound dehiscence. These sutures can be placed in several types of incisions, including a vertical midline incision, a McBurney incision (commonly used for appendectomies), a transverse incision, and a thoracoabdominal incision.
They are particularly useful in abdominal surgeries where there is a need for additional support to ensure proper healing and to prevent the wound edges from separating.
