Thank you so much for letting me know and you are that person who can exactly answers my question.
You experience lets me feel I can relax now, but a surgery instruction said : An IV and the catheter are likely to still be in place.( after waking up) I don’t know if there are a reason has to do that? If some patients are not able to control bladder for a while after waking up?
But your experience tells me that taking it before waking up is absolute OK.
There is one thing I never know but maybe you know that is when a we do an endoscope or a colonoscopy, we are put sleep for 15 or 20 minutes, it is called “ sedation” but looks like no big different with general anesthesia, sedation never needs to be put catheter but GA does. Why? Some GA only take half hour or one hour, it is no big different with sedation for surgery time.
Thanks again for your grate help!
