For how long should a post-operative bandage remain dry after suturing?

• A. 6-12 hours
• B. 1 week
• C. 24-48 hours
• D. 72 hours

Answer: (C)

Keeping the wound dry for the first 24 to 48 hours is important because the initial clot needs a dry, protected environment to stay intact and keep the wound edges in place. A dry dressing helps reduce the risk of infection, prevents maceration of the surrounding skin, and supports proper healing as the sutures hold the edges together. Shorter periods like 6–12 hours don’t protect the clot long enough, while waiting a full week is longer than necessary and can delay checking the wound and beginning normal care. Allowing dryness for 72 hours goes beyond the typical window and isn’t needed for proper initial healing. After 24–48 hours, follow the care instructions for dressing changes or showering, and monitor for signs of trouble such as increased redness, swelling, or drainage.
