Gagging represents a management problem during dental procedures. A controlled, double blind experiment on human volunteers evaluated the efficacy of nitrous oxide for suppressing experimentally-induced gagging. The ability of the subjects to tolerate palatal and oropharyngeal stimulation was evaluated by measuring the distance of the anatomic palatal and oropharyngeal structure which produce gagging. It was observed that under N(2)O/O(2) inhalation subjects tolerated a significantly more intrusive (deeper) oropharyngeal stimulation than under control conditions.
在牙科手术过程中,恶心是一个需要解决的问题。一项针对人类志愿者的对照双盲实验评估了一氧化二氮抑制实验诱导恶心的效果。通过测量引发恶心的腭部和口咽结构的解剖距离,来评估受试者耐受腭部和口咽刺激的能力。观察到,与对照条件相比,在吸入N₂O/O₂的情况下,受试者能够耐受明显更深入(更深)的口咽刺激。
