Description
Inclusion Criteria:
patients selected for this study must meet all of the following criterion:
- 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
Exclusion Criteria:
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.
