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 (see Table 1).
Conclusions There was pronounced reduction in blood loss during orthognathic procedures carried out under hypotensive anaesthesia.
