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)
