简要总结
The purpose of this study is to compare the first attempt success rate of laryngeal mask airway insertion according to the degree of head elevation.
详细描述
The purpose of this study is to compare the first attempt success rate of laryngeal mask airway insertion between 7 cm head elevation and 14 cm head elevation in patients who undergoing transurethral bladder tumor resection.
