A cardinal rule in the medical field is to not do more harm than good to the casualty. This is the reason we must be careful to protect the patient from infection or disease while attempting to treat him. There are times in combat situations when you may not have the time to wash your hands or to wear gloves and mask as you work with the casualty. This is understandable. You must work quickly to help the casualty.

Infections are prone to develop in wounds of violence. Therefore, the prevention and control of infection is one of the chief problems in emergency medical treatment and care of wounded patients. The development of infection, particularly in large wounds, increases the period of morbidity since infection produces further destruction of tissue and suppresses the healing process. Infection also has a marked effect on the final result of the injury and the mortality. Tissues destroyed by infection are usually replaced by scar tissue, which may have a harmful effect on function as well as appearance.
