Hypotensive anaesthesia and blood loss in orthognathic surgery.
OBJECTIVE
This trial aimed to determine whether hypotensive anaesthesia reduces blood loss during orthognathic surgery.


METHODS
Randomised trial.


METHODS
Subjects were allocated to hypotensive (24 patients) or normotensive (29 patients) groups, assigned by sealed envelope, before undergoing standard orthognathic procedure.


METHODS
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.
