Forty patients were studied to assess the ease of insertion of the laryngeal mask in the simultaneous presence of cricoid pressure and manual in-line stabilisation of the neck. This was compared with the normal technique of laryngeal mask insertion in the same patients. Fibreoptic views obtained through the laryngeal mask were documented on each occasion. The device was inserted successfully in all 40 patients when the head was kept in the normal position. This was achieved on the first attempt in 33 patients. When cricoid pressure and manual in-line neck stabilisation were applied, successful laryngeal mask insertion was only possible in 29 patients, with correct placement at the first attempt in 14 patients. The differences were statistically significant (p < 0.001). When cricoid pressure and neck stabilisation were applied, vocal cord visualisation through the laryngeal mask with a fibreoptic bronchoscope was only possible in 15 patients. With the head in the normal position the vocal cords were seen in 33 patients. The implications of these results are discussed with respect to the role of the laryngeal mask in the multiply injured patient.
对40例患者进行研究，以评估在同时施加环状软骨压迫和手动轴向颈部固定的情况下插入喉罩的难易程度。并将其与同一批患者正常插入喉罩的技术进行比较。每次均记录通过喉罩获得的纤维喉镜视野。当头保持在正常位置时，所有40例患者的喉罩均成功插入。33例患者首次尝试即成功。当施加环状软骨压迫和手动轴向颈部固定时，仅29例患者成功插入喉罩，其中14例患者首次尝试即正确放置。差异具有统计学意义（p<0.001）。当施加环状软骨压迫和颈部固定时，仅15例患者可通过纤维支气管镜经喉罩看到声带。当头处于正常位置时，33例患者可看到声带。针对喉罩在多发伤患者中的作用，对这些结果的意义进行了讨论。
