摘要背景 喉罩是一种介于气管内插管和面罩的通气工具.因其操作简便、对呼吸道的损伤小、刺激小、患者耐受好、并发症少;既可维持自主呼吸又能实现正压通气,故已广泛应用于临床.小儿喉罩在小儿呼吸管理中的作用和地位至关重要,不容忽视.喉罩使用过程中,出现了各式各样的置入方法.目的 小儿喉罩置入并非容易,通过研究比较不同置入技术方法,探寻小儿置入喉罩的最佳置入方法.内容 现综述小儿置入喉罩的各种方法、合适的套囊压力、置入与拔除喉罩时的麻醉深度及喉罩相关并发症.趋向 寻找一个简单、可信的麻醉深度临床监测指标是目前的研究方向,并作为判断置入喉罩的时机;进一步探讨有关喉罩套囊压力、置入与拔除喉罩麻醉深度及喉罩相关并发症,使得喉罩在今后的小儿临床使用中更加安全、有效.

abstractsBackground Laryngeal mask (LM) is an artificial airway which is situated between tracheal intubation and face mask ventilation. It is widely used clinically because of the qualities of convenience,mild damage,tolerance and less complication,and not only maintaining spontaneous respiration,but also practicing in controlled ventilation. LM in children plays an important role in management of respiration.Objective There are varieties of methods to insert LM,but inserting LM is not always easily in children. It is needed to seek the best insertion technique for classical LM in children by comparing the different insertion techniques.Content This review briefly summarizes the insertion techniques of LM,the suitable cuff pressure,anesthesia depth for LM insertion and remove,the complications of LM also be included.Trend It is a research trend to explore a simple and reliable monitoring index in anesthesia depth recently; and further investigation of cuff pressure and anesthesia depth for LM insertion and remove,the complications of LM also cann't be neglected,so that it is more safe and effective to use LM for children clinically .
