Brief Summary
|
Supraglottic airway devices (SADs), especially the laryngeal mask airway (LMA), have been extensively adopted as an alternative technique to tracheal intubation or mask ventilation for airway management in short length surgery . More and more clinicians prefer SADs now than ever before. Recent studies have shown that 50% of patients under general anesthesia in the UK are ventilated with SADs . Optimal size selection is critical to the safe and effective use of the laryngeal mask airway (LMA). ideally, the optimal LMA should be easy to insert; have an oropharyngeal leak pressure sufficient for positive pressure ventilation; a pharyngeal mucosal pressure less than capillary perfusion pressure; and be positioned such that instruments pass easily into the respiratory tract. In clinical practice, however, the weight-based criterion is not always applicable, especially for patients in asthenic or stout shape as there is no linear correlation between the upper airway anatomy and body weight due to the individual anatomical variation, as previous studies have demonstrated that the first attempt success rate of LMA insertion based on weight was as low as 77% to 82% . This study will be prospectively conducted to evaluate the efficacy of cricoid-mental distance-based method versus weight-based method in optimal size selection of Proseal LMA in adults undergoing elective surgery.
