普通喉罩与一次性喉罩的放置比较(1)
 |
【摘要】 目的 本研究比较了普通喉罩和一次性喉罩放置的成功率，解剖位置、口咽漏气压和并发症。方法 择期手术的患者120例，随机分为两组，每组60人。Ⅰ组用普通喉罩，Ⅱ组用一次性喉罩。男性患者用4号喉罩，女性患者用3号喉罩。记录拿起喉罩到插管成功再建立气道的时间。 然后用纤维支气管镜通过喉罩的通气管，检查声门、会厌的位置。测口咽漏气压。麻醉维持吸入七氟醚，静脉持续注射瑞芬太尼。术毕拔除喉罩。记录喉罩上有无染血。术后2 h随访，记录咽痛、说话、吞咽困难等并发症。结果 普通喉罩插管成功率为94.3%，一次性喉罩插管成功率为96.6%。 普通喉罩与一次性喉罩在插管成功率、建立有效气道的时间、口咽漏气压、喉罩的位置、染血、术后咽痛差异无统计学意义(P>0.05)。两组患者均无失声、吞咽困难。结论 普通喉罩与一次性喉罩临床使用效果相似，一次性喉罩可以替代普通喉罩在临床使用。

【Abstract】 Objective To investigate success ratio,anatomy position,air leakage pressure and complications between reusable laryngeal mask LMA classic and single-use LMA Unique.Methods 120 patients for selective surgery were randomized into 2 groups.There were 60 patients in each group.Patients in groupⅠwere inserted LMA classic,those in groupⅡwere inserted LMA Unique.Size 4 were used in male and size 3 in female patients.Insertion time and oralpharyngeal leakage pressure were recorded.Afiberoptic bronchoscope was applied to assess anatomical position of epiglottis and glottis.Laryngeal mask was removed when surgery finished.Blood staining on LMA and sore throat,dysphagia,dysphonia 2 hr after surgery were recorded.Results Success ratio of LMA classic and LMA Unique were 94.3% and 96.6%.There was no significant difference of success ratio,effective airway time,oralpharyngeal leakage pressure,anatomy position of LMA,blood staining,sore throat between 2 groups(P>0.05)No dysphagia and dysphonia observed.Conclusion LMA classic and LMA Unique were similar in clinical using. ......
