Opioid Free Anesthesia (OFA) - which has been applied mainly in bariatric surgery - has begun
to receive more and more attention and to obtain fanatical supporters versus conventional
anesthesia. The advantages of this type of anesthesia are mainly achieved by the action and
effect of the various drugs that compose it.
Functional Endoscopic Sinus Surgery is performed in cases where sinusitis or its
complications are difficult to treat with medication. With special cameras and endoscopes,
the narrow anatomical regions of the sinus can be depicted and precisely surgically
approached. Usually surgery is conducted under general anesthesia. According to the
literature, total intravenous anesthesia should be used for sinus surgery to achieve blood
pressure control as well as controlled hypotension to prevent intraoperative bleeding. Most
of the studies agree that the best type of anesthesia for this type of surgery is total
intravenous anesthesia. When it comes to Opioid Free Anesthesia in FESS, there are not many
studies, except of some studies that don't use solely Opioid Free Anesthesia but some of the
drugs that consist it.
Patients scheduled for elective Functional Endoscopic Sinus Surgery will be randomised in two
groups. One receiving OFA and one receiving TIVA.
