Intra-operative bleeding diminishes visualisation during functional endoscopic sinus surgery and can cause unfavourable outcomes. Dexmedetomidine is a potent alpha-2 agonist, with sympatholytic effects. This systematic review aimed to assess whether dexmedetomidine decreases intra-operative bleeding and improves operative field quality. ⋯ Dexmedetomidine is beneficial in providing good visibility during functional endoscopic sinus surgery. Controlled hypotensive anaesthesia with this medicine decreases intra-operative bleeding and enhances surgical field quality.
