An observational study in Maxillofacial Abnormalities, Blood Pressure and Anesthesia, sponsored by Singapore General Hospital. Completed at 1 site in Singapore. Per ClinicalTrials.gov, last updated 2021-03-24.
Sponsored by Singapore General Hospital · Observational
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.
