When I did my emergency room training for my EMT course, they soaked everything in a mixture of hydrogen peroxide & betadine. One guy had multiple lacerations in his hand from rusted jagged metal. The nurses had him soak in the mixture, then they rinsed his hand with sterile water so the doctor could see to do the stitches.

Wound Care Basics:
Please take a first aid course or paramedic/EMT course to get proper training.

Wound irrigation - aim is to get debris, pus out of the wound. Chlorhexidine solution > Saline > sterile water > iodine > clean boiled water. NEVER irrigate with alcohol. It will DENATURE the wound tissues and destroy the cell wall.

Skin Prep (intact skin)- blood culture / surgery Alcohol is used to kill the bacteria. Iodine is used to kill fungal spores. So in a blood culture, you would clean with alcohol / chlorhexidine then clean again with providone iodine.

Skin Scrapes/ cuts - Chlorhexidine > Saline > Sterile water > iodine > clean water

Skin scapes using small packaged First Aid items - Chlorhexidine / Cetrimide wipes (Europlast) , Benzalkonium Chloride wipes (Triad Antideptic towelette), Providone Iodine wipes (Triad brand)
