摘要
目的探讨常规喉罩插入法喉罩理想位置的到位率,提高喉罩通气技术的安全性。方法采用纤维支气管镜(fiberoptic bronchoscope,FOB)对127例使用喉罩通气全麻的成年患者,验证喉罩插入位置的到位率,对插入喉罩位置不理想者在FOB直视下进行调整。结果常规喉罩插入法到位率为76.37%,经FOB直视下调整喉罩后所能达到1级者较之调整前明显增加(P<0.05);插入喉罩位置不当(位置分级≥2级)原因主要为深度不适宜。结论采用FOB对喉罩定位是一种准确、安全的方法,可以显著提高喉罩插入的到位率。
Objective This study aims to investigative the frequency of ideal anatomic placement of the laryngeal mask airway （LMA） using the traditional blind insertion approach. Methods A total of 127 adult patients scheduled for elective surgery under general anesthesia were enrolled. After LMA was inserted smoothly, the placement was examined and adjusted under direct vision by the use of a fiberoptie bronchoscopy （ FOB ）. Results In contrast to conventional laryngeal mask insertion rate （ 76. 37%）, adjusted by FOB under direct vision,the cases which could achieve 1 grade were significantly increased than before adjustment （ P 〈0. 05）. The main reason of inappropriate location of intubation （ position classification ≥2 grade ） was the inappropriate depth of insertion. Conclusion The use of FOB in the localization of LMA is an accurate and safe method,which can significantly improve rate of laryngeal mask insertion in an ideal anatomic place.
