目的评价超声定位成年病人喉罩位置的效果:与纤维支气管镜比较.方法择期行喉罩通气全麻的妇科手术病人58例,年龄18 ～ 57岁,体重50 ～ 70 kg,体重指数20 ～ 30 kg/m2,ASA分级Ⅰ或Ⅱ级.临床评估喉罩位置正确后,先由颈部超声判断喉罩位置,再由纤维支气管镜确认位置,记录气道峰压和口咽漏气压.结果喉罩位置临床判断满意时,超声定位理想解剖位置率为69%,纤维支气管镜检查理想解剖位置率为59%,差异无统计学意义(P＞0.05).与纤维支气管镜比较,超声定位喉罩位置时口咽漏气压升高(P＜0.05).结论超声定位成年病人喉罩位置效果较好,在提示喉罩密封性方面优于纤维支气管镜,有利于改善通气条件.

Objective To evaluate the efficacy of ultrasound for placement of laryngeal mask airway (LMA) in comparison with fiberoptic bronchoscope in adult patients.Methods Fifty-eight ASA physical status Ⅰ or Ⅱ patients,aged 18-57 yr,weighing 50-70 kg,with body mass index 20-30 kg/m2,scheduled for gynecological operation under general anesthesia,underwent standard general anesthetic technique with 4 # LMA-ClassicTM.After clinical assessment of correct placement of LMA,the position of the LMA was confirmed by transverse neck ultrasound,and reconfirmed using fiberoptic bronchoscopy.The peak airway pressure and oropharyngeal leak pressure were recorded.Results When the outcome of clinical assessment of correct placement of LMA was considered as satisfactory,the rate of ideal anatomic placement assessed by ultrasound evaluation was 69 %,and the rate of ideal anatomic placement assessed by fiberoptic bronchoscopy was 59 %,and it showed that there was no significant difference in detecting the ideal placement of the LMA (P ＞ 0.05).The oropharyngeal leak pressure was significantly higher when ultrasound was used for confirmation of the correct placement of LMA than that when fiberoptic bronchoscope was used (P ＜ 0.05).Conclusion Ultrasound provides better efficacy for placement of LMA in indicating sealing of LMA than fiberoptic bronchoscope and is helpful in improving ventilation conditions in adult patients.
