Lidocaine in ERAS for FESS

Lidocaine Infusion in Functional Endoscopic Sinus Surgery

Functional endoscopic sinus surgery (FESS) is a commonly performed procedure. It is known that bleeding during FESS can affect directly to the visibility of safe landmarks and surgical outcomes.

Functional endoscopic sinus surgery (FESS) is a commonly performed procedure in the head and neck field. It is known that bleeding during FESS can affect directly to the visibility of safe landmarks and surgical outcomes.

Use of vasoactive drugs to control bleeding is not without pitfalls. Systemic effects of epinephrine may constitute a potential hazard in patients with hypertension, ischemic heart disease, anemia, preexistent liver or renal damage and endocrine dysfunction (hyperthyroidism, pheochromocytoma and diabetes mellitus).

Lidocaine is a prototypical local anesthetic, but it also has systemic effects that are mediated by inhibitory effects on N-methyl-d-aspartate receptors and leukocyte priming. Consequently, systemic lidocaine is antiinflammatory, analgesic, and antihyperalgesic. Randomized clinical trials, however, have produced mixed results. Several studies have shown reduction in postoperative opioid consumption and pain scores, whereas others have failed to show a benefit.
