Summary
The main objective of this study is to investigate the optimal anesthesia for obese patients
undergoing bariatric surgery in the strategies of positive pulmonary ventilation, tracheal
intubation technique, hemodynamic monitoring, and postoperative nausea and vomiting (PONV)
prophylaxis, as the followed:
1. To evaluate the effectiveness and adverse effect of intravenous dexamethasone for PONV
prophylaxis
2. To determine the safe inspiratory pressure to prevent the occurrence of gastric
insufflation during facemask ventilation using point-of-care ultrasonography of antrum
3. To compare the effectiveness and safety between video intubating stylet and video
laryngoscope in the placement of tracheal tubes
4. To apply minimally invasive CO monitors in guiding goal-directed hemodynamic therapy and
assess its impact on major complications and postoperative recovery
