The purpose of this research is to develop from enhanced multimodal anesthesia care to verify and optimize ERAS strategies for orthognathic surgery. If the elements of anesthesia care can be accurately controlled, the harmful pressure factors caused by surgery can be minimized and the patients undergoing facial surgery can be improved.
Orthognathic surgery (Orthognathic surgery) is currently one of the most commonly performed surgical items in oral and maxillofacial surgery because it corrects facial deformities, improves teeth chewing and face glowing. In general, the kind of operations are performed under nasotracheal intubating general anesthesia.
Due to the patients were required for motionless, low pressure, controlled ventilation, and adequate analgesia during anesthesia undergoing orthognathic surgery, advanced multimodal anesthesia care developing to the Enhanced Recovery After surgery (ERAS) should be conducted under patient safety. The ERAS concept emphasizes the importance of clinical multidisciplinary teamwork cooperation including of oro-surgeon, anesthesiologist, operating and post-anesthesia care nurses. The core elements of ERAS lies in the management of the entire peri-operative period of anesthesia. In clinical practice, focus on entire anesthesia care during the operation includes of precise anesthesia depth, adequate muscle relaxation, multiple modes of pain controlled and adequate analgesia, stable body temperature maintenance, use of goal-oriented infusion therapy, early extubation, and prevention of postoperative nausea and vomiting.

| Measure | Description | Time Frame |
|---|---|---|
| permitted hypotension during surgery with adequate depth of anesthesia and cardiac output | to decrease intra-operative bleeding as patient undergoing oromaxillofacial surgery, intentional hypotension is allowed. however, adequate depth of anesthesia, proper cardiac output, respiratory parameters, temperatures should be monitored | intraoperative 2-6 hours |
| consumption of inhaled and intravenous anesthetics | to maintain adequate depth of anesthesia during intentional hypotension, consumptions of inhaled and intravenous anesthetics are calculated | intraoperative 2-6 hours |
| Measure | Description | Time Frame |
|---|---|---|
| time to successfully extubate the nasotracheal tube after anesthesia | early extubation allowable | from the end of surgery to the post-anesthesia care, assessed up to one hour |
| safely discharged from post-anesthesia care unit (postoperative recovery room) |
