简要总结
evaluate the efficacy of the ultrasound approach in predicting difficult mask ventilation in a heterogeneous population of patients undergoing general anesthesia.
详细描述
Preoperative ultrasound of the upper airway and detection of 5 ultrasound measurements:
Trachea-skin distance at the level of the thyroid isthmus; Trachea-skin distance at the jugular level Front commissure-skin distance; Distance from skin to the thyroid membrane Distance between hyoid bone and skin. Comparison of this measurement with HAN-scale for prediction of difficult mask ventilation during general anesthesia

结局指标
主要结局
ultrasound assessment
时间窗: Ultrasound assessment will be performed 30 minutes before induction of general anaesthesia and the mask ventilation evaluation will be performed 3 minutes after induction with ''Han scale".
the association between the ultrasound measurement and the difficulty of mask ventilation measured with the "Han scale". "Han scale" classify mask-ventilation in five grade of progressive difficulty: 0) mask ventilation did not attempt, 1) easy 2) difficult and requiring oral airway 3) very difficult requiring two practitioners 4) unable to mask ventilate. "Han scale" is the only grading scale available used routinely in anesthesiologic assessment of bag-mask ventilation.
