Swabbing the site with alcohol is done routinely by doctors. I have been doing the same for years. This practice is more or less of psychological value. The bacteria are not killed in such a short time. Many diabetic patients have been taking insulin injections for years without swabbing the skin with spirit and they have no problem. The healthy skin has got too little number of bacteria to create problem. The tip of the needle is too sharp to put in the enough number of bacteria to create any problem. But this harmless practice will continue in coming years also.
If there is any micro organism or bacteria on the skin swabbing would prevent the needle from transferring it into the blood stream.
Because cruel and unusual punishment is both unconstitutional and morally impermissible - by swabbing the arm they dull the pain of the needle insertion, as the injection itself is not designed to cause physical pain.
to prevent infection
Kills germs on the skin that may cause an infection
The mucous membrane provides lubrication and prevents infection by trapping bacteria before it enters the lungs or moving bacteria into the stomach where acids kill them.
The skin is cleaned with spirit before injection. It may just feel a bit cold
This is a rare complication of a minimally invasive test (biopsy, injection, aspiration, etc.). You should notify your doctor of the infection, and probably go back in to have the infection evaluated. Because the break in your skin is known to extend to an organ or structure deep below, your doctor may prescribe antibiotics to clear it up before the infection can track the whole way down.
Any infection in the body would be of concern to an orthopedic surgeon. as infection can travel from one part of the body to another. Orthopedic surgeons are particularly paranoid about the risk of infection as the bone is about as deep as you can go in the body. I suggest you speak with him/her about this before you go under the knife.
Prophylaxis for what? For something to be prophylactic, it has to prevent something before it happens....... Could be pain, pregnancy, infection, etc.

first efi was 1966, but was not perfected or put into use until much later. the fuel injection on cars to day is port injection, before that was bank injection, throttle body injection, the vortec.
Belly button rings can cause infection very easily if not cleaned at least once a day. The best way to prevent an infection is to clean it with antibacterial soap, such as Dial, once or twice a day. Applying alcohol or peroxide can dry the skin out and help with infection, so do not use those. Do not use lotions around the belly button as this can cause a moist environment for bacteria to set in and cause infection. The last thing able to prevent an infection is to not touch the piercing until the belly button is healed. Bothering it before then can easily move germs back and forth between the ring and wound, so leave it to set before taking it out.
