How do you differentiate direct pressure from wound packing?

• A. Direct pressure controls superficial bleeding; packing addresses deeper cavity bleeding
• B. Wound packing addresses superficial bleeding
• C. They are the same technique
• D. Direct pressure is for bleeding in the deep cavities

Answer: (A)

Direct pressure and wound packing address bleeding in different locations. Direct pressure works by pressing on the outside of the wound to compress the surface vessels and stop bleeding at the wound margin or from superficial vessels. It’s the first-line method for external, superficial bleeding.

Wound packing, on the other hand, places gauze or similar material into the wound cavity to fill the space and apply internal pressure (tamponade) on deeper bleeding within the wound tract. This is used when the bleeding comes from deeper vessels or recesses that surface pressure can’t reach.

So the key idea is that direct pressure controls superficial, surface bleeding, while wound packing controls bleeding from deeper areas inside the wound cavity. The other statements either swap these roles or claim the techniques are the same, which isn’t accurate.
