Question

why long the alcoholic cotton is placed on the puncture ? give reasons.​

Answer 1

Alcohol swabbing before an injection is a long-standing, widely used infection control practice. It’s thought that prepping the skin using alcohol swabs removes bacteria that could be pushed into the puncture and might cause an infection. To clean the skin before vaccination or other injection, suggested standard practice according to the World Health Organisation (WHO) is to swab the injection site with a saturated 60% to 70% alcohol swab for 30 seconds, then let the area dry for another 30 seconds so that the alcohol doesn’t enter the puncture and sting.
