Explanation:
Impregnation with alcohol prior to injection is a long-standing and widely used infection control practice. Prepping the skin with alcohol wipes is thought to remove bacteria that can enter the injection and cause infection. To clean the skin before a vaccination or other injection, the standard practice recommended by the World Health Organization (WHO) is to wipe the injection site with saturated 60-70% alcohol for 30 seconds and then let the area dry a second time 30 seconds to prevent alcohol from entering the needle.
However, whether this practice is effective in reducing infection has been debated for years. Few patients arrive for the injection with dirty skin. And several health organizations - including the WHO and the Public Health Agency of Canada - say there's no need to wipe the skin with alcohol if it's visibly clean. However, alcohol imbibition remains a common and routine practice in hospitals and other health care settings across Canada and around the world, and members of the health care community continue to wonder if there is evidence that it prevents infection.
