Emergency airway management by intensive care unit nurses with the intubating laryngeal mask airway and the laryngeal tube

When using the laryngeal tube and the intubating laryngeal mask airway (ILMA), the medium-size (maximum volume 1100 ml) versus adult (maximum volume 1500 ml) self-inflating bags resulted in significantly lower lung tidal volumes. No gastric inflation occurred when using both devices with either ventilation bag. The newly developed medium-size self-inflating bag may be an option to further reduce the risk of gastric inflation while maintaining sufficient lung ventilation. Both the ILMA and laryngeal tube proved to be valid alternatives for emergency airway management in the experimental model used.

在使用喉管（laryngeal tube）与插管型喉罩气道（intubating laryngeal mask airway, ILMA）时，相较于成人规格（最大容积1500ml）的自充气呼吸囊（self-inflating bag），中号规格（最大容积1100ml）的自充气呼吸囊可使肺潮气量显著降低。当两种气道装置搭配任意一款呼吸囊使用时，均未发生胃胀气情况。本次新研发的中号自充气呼吸囊，可在保障肺通气充足的前提下，进一步降低胃胀气的发生风险。在本实验所采用的模型中，插管型喉罩气道与喉管均被证实为紧急气道管理的可靠替代方案。
