- •Age is between 17 to 65 years old;
- •ASA (Amecican Society of Anesthesiology ) scores I-II;
- •Actual weight is between 30 to 100 kilogram;
- •Patients undergo selective supine operations under general anesthesia (laryngeal mask);
- •Patients agree to participate in our study and sign Informed Consent Form
排除标准
- •Patients cannot participate in this study if they have any of the following conditions:
- •Airway stenosis, history of airway masses etc, whicn may cause obstruction to ventilation;
- •Swelling of the neck caused by huge mass in the neck and history of neck surgery etc, which doesn't contribute to ultrasound observation;
- •Stomach fullness, intestinal obstruction, gastroesophageal reflux disease etc, which may cause reflux aspiration.
结局指标
主要结局
Ultrasound scoring system
时间窗: during procedure (after laryngeal mask's placement)
Anesthesiologist who are familiar with ultrasound would scan three planes of neck
Air leakage test grading system
时间窗: during procedure (after laryngeal mask's placement)
Anesthesiologist would auscultate the degree of leakage
Fiberoptic scoring system
时间窗: procedure (after ultrasound examination or leakage test)
Anesthesiologist would confirm the position of LMA by fiberscope
次要结局
- Complications related to LMA (laryngeal mask airway )(24 hours after surgery)
