VL(ビデオ喉頭鏡)の利点と欠点 学習効果が高い 状況が一目瞭然 Difficult airwayで成功率が高い 食道挿管・口腔外傷が少ない 頸部制限があっても容易 見えてても挿管困難 曇り/分泌物に弱い 費用がかかる DLが下手になる “I will unequivocally state that it is wrong for people to practice direct laryngoscopy in 2012.” — Ron Walls “All departments should have access to video laryngoscopy equipment” — Scott Weingart
