Review of Anaesthetic Practice in Orthognathic Surgery

Completed

• Conditions: Blood Pressure; Anesthesia; Maxillofacial Abnormalities

• Registration Number: NCT04813289
• Lead Sponsor: Singapore General Hospital

Brief Summary

Orthognathic surgeries for maxillofacial deformities are commonly performed globally. However, they are associated with significant blood loss which can affect the surgical field and result in blood transfusion and its risks. We aim to review the different hypotensive anaesthetic practices for orthognathic surgeries, and their effects on intraoperative blood loss and transfusion requirements.
