Radial graph of mean scores in effective cases of 3 groups.
Plotted markers indicate mean score values of effective cases in each group. In groups A1 and A2, almost all difficulties were relieved, but we must pay attention to airway management, especially in off patients in the A2 group who were administered a high dose of flunitrazepam. Values for coughing by aspiration are the same in groups A1 and A2. By contrast, in group R, clenching and uncooperative behavior were still observed, but the score related to the airway was zero in all cases.
