True, But again that goes as well for just about any kind of bandaging you use for a bad injury. Even guaze bandages once applied should remain in place until proper medical treatment such as a ER or Doctors office. As you know removing such bandages could result in reopening a wound and starting bleeding again.Always be extremely careful when removing any clotting agent or wound packing material from a wound. This can cause bleeding to reoccur, especially if a major artery is involved. Improper removal can also introduce infection to the site.
