Can you sleep under brachial plexus anesthesia

In the case of simple brachial plexus anesthesia, there will be no sleep after anesthesia. It may be that the anesthesiologist, in order to reduce the anxiety of the patient during the operation, will give the patient some sedative to put the patient to sleep. This can make the patient's vital signs more stable, can also make the anesthesia effect of surgery better, can also extend the anesthesia time of surgery, but also make the anesthesia effect more comfortable.

But when you give sedatives, when you put the patient to sleep, you have to give the patient mask oxygen, so that you don't have a drop in blood oxygen, you might have asphyxiation. But when you give sedatives, you don't want to give the sedatives superimposed, so that after the sedatives are given, the patient will not pant and his breathing will disappear.
