Drapes required for a Lithotomy (Perineal). Which item is used to cover abdomen and perineum with a double-fenestration design?

• A. Perineal procedure drape or double-fenestration drape for abdomen and perineum
• B. Four towel drapes for each incision site
• C. Bottom drape to place under the elevated leg and foot
• D. Top sheet (half, 3/4, or full plain sheet)

Answer: (A)

Providing a sterile field for both the abdomen and the perineal area in lithotomy requires a drape designed with two openings. A perineal procedure drape with a double-fenestration does exactly this: one fenestration covers the abdomen and the other the perineum, keeping both operative sites accessible while maintaining a continuous sterile barrier. This design minimizes shifting and exposure of non-sterile skin around either site and reduces the need for multiple separate drapes. Other options don’t offer this dual opening in one consistent sterile cover: towel drapes for each site can create gaps and are less secure; a bottom drape under the leg doesn’t address the abdomen and perineum as a single sterile field; a plain top sheet isn’t a sterile drape and won’t provide the necessary barrier.
