The LMA Supreme has been suggested for use in emergency situations by medical personnel with no experience in endotracheal intubation. We evaluated the LMA Supreme when inserted by non-anaesthetists, firstly in a manikin and then in patients. Fifty airway novices inserted a LMA Supreme in a manikin without any complications so we proceeded to the patient phase. Fifty airway novices inserted the LMA Supreme in anaesthetised patients undergoing elective surgery. First time insertion success rate was 86% and overall insertion success rate was 100%. Mechanical ventilation was successful in all cases. Median (IQR [range]) time to establish an airway was 34 s (26-40 [18-145] s). Median (IQR [range]) pharyngeal seal pressure was 23 cmH(2)O (19-28 [13-40] cmH(2)O). There were no important complications. Results are consistent with previous studies of use of the LMA Supreme by airway experts. We conclude that the LMA supreme is suitable for use by airway novices. Further research is needed before it may be recommended for cardiopulmonary resuscitation and emergency airway use.
喉罩 Supreme 已被建议供无气管插管经验的医务人员在急救情况下使用。我们评估了非麻醉师插入喉罩 Supreme 的情况,首先在模型上,然后在患者身上。50 名气道新手在没有任何并发症的情况下在模型上插入了喉罩 Supreme,因此我们进入了患者阶段。50 名气道新手在接受择期手术的麻醉患者中插入了喉罩 Supreme。首次插入成功率为 86%,总插入成功率为 100%。所有病例均成功进行机械通气。建立气道的中位(IQR [范围])时间为 34 秒(26-40 [18-145] 秒)。中位(IQR [范围])咽密封压为 23cmH2O(19-28 [13-40] cmH2O)。没有发生重要并发症。结果与之前气道专家使用喉罩 Supreme 的研究一致。我们得出结论,喉罩 Supreme 适合气道新手使用。在推荐其用于心肺复苏和紧急气道使用之前,还需要进一步研究。
