ABSTRACT

Orthognathic surgery, is widely used in the world, because correct dentofacial disharmonies, these are very precise procedures. Intraoperative bleeding, which occurs in these surgeries, is important, therefore, the chances are for a blood transfusion. Decrease bleeding, is a goal in the anesthetic management. The agonist α₂, as the dexmedetomidine, reduce the requirements of other drugs employed both in the induction as the anesthetic maintenance, action which is apparently related to the inhibitory effect on the central transmission of type antidepressant. Results: We included 55 records of patients, both sexes, undergoing orthognathic surgery, with nasal intubation, maintenance anesthetic with isoflorane or sevoflorane plus dexmedetomidina infusion. Found bradycardia of 12%, mean blood pressure around the 70 mmHg, average consumption of 43.5 mL of isoflorane and 78 mL of sevoflorane, dexmedetomidine 191.64 µg, fentanyl 254.53 µg, bleeding of 478 mL. Conclusion: The use of adjuvant dexmedetomidine in the anesthetic management is another option, which maintains tension figures suitable, without significant bleeding decreasing transfusion requirement.
