One Thing Less To Worry About
I noticed the capped valve which was part of the contraption and wondered what its function was, but it sure didn't take long for me to find out; it was used to insert the anesthetics into my bloodstream. I am not sure if it was used for anything else after that, because I conked out shortly after it was administered.
Those luer-activated needleless valves sure come in handy, but when not constantly kept disinfected they are a potential open door for bacteria and viruses to find their way in as well. That is why infection control is of the utmost importance, but that also means more work for the already swamped nurses.
It is a good thing that the time and work involved in that is cut short substantially by the simple application of disposable caps which provide protection against any other possible infections. At least that is one thing less we have to worry about!
