美迪斯可弯曲喉罩与Ambu AuraFlex可弯曲喉罩在小儿眼科手术中的比较

Comparison of Medis Flexible Laryngeal Mask Airway and Ambu AuraFlex Flexible Laryngeal Mask Airway in Pediatric Ophthalmic Surgeries

目的比较美迪斯可弯曲喉罩与Ambu AuraFlex可弯曲喉罩应用于小儿眼科手术麻醉的效果。方法择期行全身麻醉眼科手术患儿80例,性别不限,ASAⅠ~Ⅱ级,年龄1~5岁,体重≥10kg,术前评估无困难气道指征,采用随机数字表法将患儿分为美迪斯喉罩组(M组)与Ambu AuraFlex喉罩组(A组)。记录两组喉罩置入耗时、置入次数、手指引导置入率、置入难度、口咽部漏气压、纤维支气管镜下对位情况及术后有无喉罩沾血、声音嘶哑和咽部疼痛等并发症情况。结果M组气道密封压高于A组(P<0.05),但M组置管时间及手指引导置入率均高于A组(P<0.05)。两组在置入次数、置入难度、纤维支气管镜对位分级等指标比较,差异无统计学意义(P>0.05),在术后喉罩沾血、声音嘶哑和咽部疼痛等方面比较,差异无统计学意义(P>0.05)。结论美迪斯可弯曲喉罩气道密封压高于Ambu AuraFlex可弯曲喉罩;但AmbuAuraOnce可弯曲喉罩置入耗时及食指引导置入率均低于美迪斯可弯曲喉罩。

Objective To compare the clinical effect of Medis flexible laryngeal mask airway(FLMA)and Ambu AuraFlex FLMA in pediatric ophthalmic surgeries.Methods 80 patients,aged 1-5ys,ASAⅠ-Ⅱ,≥10kg,no difficult airway characteristics,were enrolled in this study.They were randomly divided into Group M(Medis FLMA)and Group A(Ambu AuraFlex FLMA).Recorded the insertion time,attempts,finger assistance,insertion difficulty,oropharyngeal leak pressure(OLP),fiberoptic grade of view and complications such as blood stain,hoarseness and sore throat.Results Group M showed higer OLP than Group A(P<0.05),but Group M needed longer insertion time and more finger assistance than Group A(P<0.05).There were no statistical differences between the two groups in attempts,fiberoptic grade of view,insertion difficulty and those complications.Conclusion Medis FLMA showed higher OLP than Ambu AuraFlex FLMA,but Medis FLMA needed more insertion time and finger assistance than Ambu AuraFlex FLMA.
