简要总结
The size selection of Laryngeal Mask Airway classic is usually followed the manufacturer's recommendation based on the patient's ideal weight. But sometimes the patient is tall and slim, the actual weight is much less than the ideal weight. This phenomenon might affect the success rate of insertion. Previous studies had demonstrated that the selection of Laryngeal Mask Airway size based on ideal weight could improve the success rate of insertion; therefore, this study was designed to prove whether this conclusion also applies to the tall and thin patients.
详细描述
One hundred and eighteen patients adult patients，actual body weight much less than ideal body weight will be assigned randomly to two groups (Actual weight Group or Ideal weight Group). Size selection was guided by the recommendations of manufacturer, patients will be based on the actual body weight in Actual weight Group while ideal body weight in Ideal weight Group.
The success rate of first attempt，number of adjustments, insertion time, ease of insertion, overall success rate, oropharyngeal leak pressure and fiberoptic view will be recorded and compared. The occurrences of respiratory complications such as sore throat, hoarseness, and dysphonia will be observed and recorded.
