正中入路和右侧入路的喉罩置入难易比较

Comparison of the difficulty of the median approach and the right approach for the laryngeal mask airway insertion

目的比较正中入路和右侧入路的喉罩置入难易程度。方法择期手术行喉罩置入患者60例,随机分为正中入路组(A组)和右入路组(B组),每组30例。A组以正中入路置入喉罩,B组以右侧入路置入喉罩,记录置入时间、置入评分、置入前后的SBP、DBP、MAP、HR值。结果两组置入喉罩前后的SBP、DBP、MAP和HR值无明显差异(P>0.05),但B组的置入时间(20.43±7.54)s短于A组(35.80±30.73)s,置入评分优于A组(P<0.05),首次置入成功率B组(93%)高于A组(70%)(P<0.05)。结论置入喉罩右侧入路的方法更加简便。

Objective To compare the difficulty of the median approach and the right approach for the laryngeal mask airway insertion. Methods Sixty cases of LMA insertions were random- ly divided into two groups （n = 30） ： median approach group （group A） and right approach group （group B）. The group A was in the middle way method of LMA insertion, the group B was in the right-side into the path of LMA insertion, and the insertion time, insertion score, before and after the insertion of SBP, DBP, MAP and HR were recorded. Results Two groups of patients with LMA of SBP, DBP, MAP and HR value were not significantly different （P 〉 0.05 ）, but the insertion time （20. 43 ±7.54） s of group B was shorter than that of the group A （35.80±30. 73 ） s, insertion score better than the group A （P 〈 0. 05 ）, the first time success rate was 93% of group B which higher than that was 70% of group A （ P 〈 0. 05 ）. Conclusion The right approach is more convenient.
