Summary

Gastric regurgitation increases the risk of pulmonary aspiration in surgical patients receiving general anesthesia because of depression of gastro-esophageal reflux. In addition, some patients may have higher risk of aspiration as a result of reduced gastric emptying and gastroesophageal reflux, prolonged surgical time, and laparoscopic surgery. Second-generation supraglottic airway device (SAD) provides an additional channel to facilitate the drainage the gastric content to prevent from aspiration, which was routinely used in surgeries. Currently, multichannel intraluminal impedance-pH (MII-pH) monitoring, which combines multiple impedance channels to conventional pH catheters, is regarded as the most sensitive technique for detecting reflux events. Therefore, application of MII-pH monitoring on the SAD-based general anesthesia may help to detect ongoing reflux/regurgitation in the esophagus of patients during perioperative period. The hypothesis of the present study is that the occurrences of gastroesophageal regurgitation during general anesthesia may be influenced by the several factors, such as abdominal insufflation during laparoscopy, longer surgical time, Trendelenburg position, higher body weight, etc.

Conditions

  • The Episodes of Gastric Regurgitation

Interventions

OTHER

the effect of surgical position

Investigators do not have intervention in the observation study. Investigators only use the MII-pH catheter to observe the episodes of gastric regurgitation in patients receiving supraglottic airway device under general anesthesia. Thus, investigators are going to observe the effect of surgical position change, body weight, surgical time. And investigators will have a control group, which patients undergo elective surgeries without surgical position change, no longer surgical time, and normal range of body weight.
