Once irrigation has been accomplished, eyewear is typically not necessary, but the rescuer should still be wearing protective gloves. Remember to wash your hands before and after donning the gloves. Soap, water, and gloves are a tough trio on germs. In the absence of protective gloves, the rescuer may improvise with clean plastic bags over her or his hands. With relatively minor wounds, to prevent sharing germs, the patient may be directed in the management of his or her own wound (including control of blood loss).
Contusion
Bruises seldom require emergency care, but large bruises benefit from cold, compression, and/or elevation. Substantial bruises should cause you to assess the patient for damage to underlying structures, such as bones and organs. Large bruises should be protected from freezing in extremes of cold because a bruised area will freeze sooner than normal skin.
Abrasions
Abrasions are the exception to the rule of wound cleaning: You need to scrub within the wound to achieve adequate cleaning. A sterile gauze pad is adequate for scrubbing. Scrubbing may be enhanced by using any soap, but all soap should be carefully rinsed and then irrigated from the wound after scrubbing. Green Soap Sponges are packaged with soap and water already in the sponge, making them useful additions to first-aid kits. It is important to remove all embedded debris not only to reduce the risk of infection but also to prevent subsequent “tattooing” (scarring) of the skin. With a deep abrasion, self-scrubbing is seldom successful due to the high level of pain associated with the exposed nerves.
After cleansing, abrasions can be kept moist to avoid desiccation and speed healing with microthin film dressings that can be left in place until healing occurs. Without microthin film dressings, a topical agent, such as an antibiotic ointment, can be applied, followed by a dressing of a sterile gauze pad or a roll of sterile gauze to keep the ointment in place. Tape, an elastic wrap, or some other holder may be used to hold a sterile gauze pad in place. Ideally, gauze dressings should be changed twice a day, or at least once a day, as well as any time the gauze gets wet.
