What could happen when I wake up from anesthesia?

ElieBR, Thanks for your question. It is very common for patients to be nauseated after surgery. There are many things that could be done to prevent these symptoms, you could/should ask your plastic surgeon if he/she uses any of these methods:Before surgery: Emend taken the morning of surgeryDuring surgery: steroid, zofran, acid blocker (for stomach acid), scopolamine patch, using a throat pack (to prevent any blood from going into your stomach during surgery)After surgery: zofran, phenergan, scopolamine patchIt is not necessary to use all of these medications, but some combination of these medicines should be used. Best of luck!

Some patients develop post operative nausea and vomiting but there are ways for surgeons and anesthesiologists to curb this issue.Hope this helps. Raja Mohan MD

Any surgery has the potential to cause nausea and vomiting so there is a chance.  It is unlikely to upset the result though.
