About

The aim of this study is to evaluate the effect of the addition of epinephrine to bilateral real time ultrasound guided pterygopalatine ganglion blocks on intra-operative bleeding and blood loss during functional endoscopic sinus surgery (FESS).

Full description

FESS is the treatment of choice in patients with medically refractory chronic rhinosinusitis and chronic polypous rhinosinusitis. This surgery relies on minimal surgical site bleeding to be performed efficiently and safely. Hemorrhage during FESS decreases visibility of the surgical field and this increases the risk of vascular, orbital and intracranial complications as well as procedural failure. Thus the importance of minimizing surgical bleeding in this procedure. The maxillary artery is the primary blood supply for the sinuses and midface. Conceptually the application of epinephrine into the pterygopalatine fossa onto the maxillary artery with the block should result in constriction of this artery and subsequently, less bleeding from the surgical site. This randomized, double-blinded, controlled pilot study will investigate the utility of addition of epinephrine to bilateral pterygopalatine ganglion blocks performed under ultrasound guidance in minimizing surgical site bleeding and overall blood loss and the potential for shortening the surgical time.
