Truview喉镜气管插管在婴儿应用的安全性和可行性

The feasibility and safety of intubation with Truview laryngoscope in the infants

目的观察Truview喉镜气管插管在婴儿应用的安全性和可行性。方法选择62例ASAⅠ或Ⅱ级患儿,年龄3～12月,拟在经口气管插管全身麻醉下实施择期整形外科手术,随机分为Truview喉镜组(T组)和Macintosh喉镜组(M组),每组31例。记录插管时声门暴露分级、麻醉诱导前、诱导后、气管插管后即刻及气管插管后1、2、3、4和5min的HR和SpO2;记录暴露声门时间、气管插管时间及气管插管的并发症。结果与M组比较,T组喉镜暴露声门程度差异无统计学意义,但暴露声门时间及气管插管时间相对延长(P<0.05);两组患儿气管插管时HR均有增快(P<0.05),但两组间HR和SpO2差异无统计学意义;插管时及拔管后两组均未见明显并发症。结论 Truview喉镜可以安全地应用于婴儿气管插管,但暴露声门和气管插管耗时相对延长。

Objective To observe the feasibility and safety of intubation with Truview laryngoscope in the infants. Methods Sixty-two infants scheduled for selective plastic surgery under general anesthesia were randomly divided into 2 groups of T （Truview laryngoscope） and M （Macintosh laryngoscope） with 31 cases each. The view of glottic exposure were recorded. HR and SpO2 were recorded before and at intubation, 1,2,3,4 and 5 min after intubation. The time for glottic exposure and intubation and complications during intubation were recorded as well. Results The view of glottic exposure of both groups was similar. The times for glottic exposure and intubation were longer in group T than those in group M（P〈0.05）. There were no significant differences in HR and SpO2 between two groups. There were no significant complications related to intubation in two groups. Conclusion Compared to Macintosh laryngoscope, Truview is an effective intubation tool for infants with longer times for glottic exposure and intubation.
