Effect of Body Positioning on Upper Airway Patency During Induction of Anesthesia in Obese Patients

NCT01811069 · Status: COMPLETED · Type: OBSERVATIONAL · Enrollment: 13

No results posted yet for this study

Summary

Upper airway obstruction (UAO) during induction of general anesthesia is a frequently occurring complication. The mechanism of UAO during anesthesia shares many similarities with the upper airway obstruction observed during obstructive sleep apnea (OSA). Obesity is major risk factors for OSA and obese patients have a higher prevalence of UAO during anesthesia. The change of body position improved upper airway stability during sleep in patients with OSA.We hypothesis that the 30˚ reverse trendelenburg body position maintain airway patency in obese patients during general anesthesia.
