Thirty patients were randomly allocated to one of two groups in order to compare the use of a split laryngeal mask airway with the Berman II airway as aids to training in fibreoptic laryngoscopy. In both groups anaesthesia was induced with propofol and maintained with isoflurane in N2O/O2 (FIO2 = 0.5). The fibreoptic laryngoscope was guided towards the larynx using the split laryngeal mask airway in group 1 and the Berman airway in group 2. The tracheas of all patients were successfully intubated at the first attempt and no patient's peripheral oxygen saturation decreased below 92%. Two min after intubation mean heart rate was significantly greater in group 1 (101 beat.min-1) than in group 2 (84 beat.min-1) (P < 0.05). The split laryngeal mask is a useful aid to training in fibreoptic intubation and may allow better airway control than the Berman II intubating airway.
为比较喉罩气道分离器与Berman II气道作为纤维喉镜检查训练辅助工具的使用情况，将30例患者随机分为两组。两组均采用丙泊酚诱导麻醉，并用异氟烷在N2O/O2（FIO2 = 0.5）中维持麻醉。第1组使用喉罩气道分离器引导纤维喉镜朝向喉部，第2组使用Berman气道。所有患者的气管均在首次尝试时成功插管，且无患者外周血氧饱和度降至92%以下。插管后2分钟，第1组的平均心率（101次/分钟）显著高于第2组（84次/分钟）（P < 0.05）。喉罩气道分离器是纤维插管训练的有用辅助工具，与Berman II插管气道相比，可能能更好地控制气道。
