1. Infection Prevention
Before the advent of strong antibiotics, small dirty wounds probably killed more people than major traumatic injuries. And without a supply of antibiotics in your medical gear, you'll be at risk just the same in modern times. Clean all wounds, big and small, with disinfectant. Irrigate wounds with clean (disinfected) water to remove dirt and debris. Cover all open injuries with sterile dressings, and keep your patient well fed and hydrated to maintain his or her immune system and keep it at peak performence.
