I think anytime you go to a hospital for a surgery -
it is important to have someone there to be with you and watch over things.
You can get permission for family/someone to stay all night with you- or just do it- as long as there is no excessive noise or disruptions.

Be polite but firm and go up the chain of command when that is needed to get results.
Stand up for your rights - patients are the reason they get a paycheck!
