中文摘要:
      目的:观察改良普通喉罩辅助纤维支气管镜(fiberoptic bronchoscope,FOB)气管插管在困难气道患者中的应用效果。方法选择经熟练麻醉医师使用直接喉镜插管2次失败的择期全麻手术患者40例,男21例,女19例,年龄30~55岁,ASA Ⅰ或Ⅱ级,随机分为两组,每组20例。研究组(LMA-FOB 组)将普通喉罩进行改良(剪开喉罩出口栅栏分隔处,剪短通气管),辅助 FOB 气管插管;对照组(FOB 组)经口垫直接使用 FOB 气管插管。观察咽部解剖结构显露分级,记录一次插管成功率及插管时间,记录拔除喉罩带血和术后咽喉部疼痛、声音嘶哑等不良反应的发生情况。结果与FOB 组比较,LMA-FOB 组咽部解剖结构显露分级明显提高(Ⅰ/Ⅱ/Ⅲ/Ⅳ级:15/4/1/0 vs.8/4/5/3,P <0.05),一次插管成功率明显提高(90% vs.60%,P <0.05),插管时间明显缩短[(75±20)s vs.(105±25)s,P <0.05)]。术后 LMA-FOB 组仅1例喉罩带血,1例咽部轻微疼痛。结论对可能存在困难气道的患者,采用改良普通喉罩辅助纤维支气管镜引导气管插管可明显提高咽部解剖结构显露分级,提高一次插管成功率,缩短插管时间,术后无明显不良反应,是一种比较安全有效的方法,有一定的临床应用价值。
英文摘要:
      Objective To observe the clinical effect of modified laryngeal mask airway combining fiberoptic bronchoscope intubation in difficult airways.Methods Forty patients,21 males and 1 9 females,aged 30-55 years,ASA physical status Ⅰ or Ⅱ,scheduled for elective general anes-thesia surgery after failure to direct laryngoscope two attempts were randomly divided into two groups,20 cases in each group.Patients in group LMA-FOB underwent intubation with modified la-ryngeal mask airway combining fiberoptic bronchoscope,and patients in group FOB underwent intu-bation with fiberoptic bronchoscope.The fiberoptic bronchoscope score,the intubation time and the rate of successful intubation at first attempt were recorded.All the patients were followed up postop-eratively for adverse effects.Results The fiberoptic bronchoscope scores (Ⅰ/Ⅱ/Ⅲ/Ⅳ:1 5/4/1/0 vs. 8/4/5/3,P <0.05)and the rate of once successful intubation (90% vs.60%,P <0.05)was signifi-cantly higher,and the intubation time [(75 ± 20)s vs.(105 ± 25 )s,P < 0.05 ]was significantly shorter in group LMA-FOB than that in group FOB.In group LMA-FOB,one patient had blood stain in the LMA and one patient felt slight sore throat.There were no significant adverse effects in the two groups.Conclusion Modified Laryngeal mask airway combining fiberoptic bronchoscope intubation in difficult airways was effective to improve the grade of the view of the larynn and the success rate of intubation and shorten the intubation time.No significant adverse effect postoperatively was reported. It is relatively safe,effective and promising in patients with difficult airway.
