Abstract
OBJECTIVE: This trial aimed to determine whether hypotensive anaesthesia reduces blood loss during orthognathic surgery. DESIGN: Randomised trial. INTERVENTION: Subjects were allocated to hypotensive (24 patients) or normotensive (29 patients) groups, assigned by sealed envelope, before undergoing standard orthognathic procedure. OUTCOME MEASURE: Median blood loss was measured. RESULTS: A significant reduction in blood loss was seen with hypotensive anaesthesia. CONCLUSIONS: There was pronounced reduction in blood loss during orthognathic procedures carried out under hypotensive anaesthesia.
