Can I have surgery with anxiety/white coat syndrome?

Your blood pressure should be able to be controlled during your rhinoplasty.  If you are having a general anesthesia, this will frequently lower the blood pressure during the procedure.  You may just want to mention your issue to your surgeon and anesthesiologist prior to your surgery.  

Your anxiety about surgery is actually very normal.  In order to address the expected, I typically give patients a prescription for Valium, which they can take prior to arriving for the procedure.  Most blood pressure situations can be managed under anesthesia, as sedation tends to lower blood pressure.  I have had to cancel a few cases related to very high pressure, but such situations are very rare. 

It is very normal to have anxiety when you are at the doctor's office and especially the morning of the surgery. The anesthesiologist will evaluate you the morning of your surgery and will medicate you accordingly. You may be given some anti-anxiety medication prior to being taken back to the operating room. You will be monitored throughout your surgery (blood pressure and pulse) and following your surgery. Let your surgeon and anesthesiologist know your situation.

Good Luck with your surgery!
