“气管插管鉴定囊”在急诊抢救插管中的应用——与听诊法对导管位置判定的比较

Comparison of tracheal detecting-bulb and stethoscope during intubation in critically ill patients

目的 观察“气管插管鉴定囊”在抢救危重病人气管内插管时对导管位置判定的作用 ,并和传统听诊法做比较。方法 5 7例重症抢救病人 ,气管内插管后随机分为两组 ,Ⅰ组病人 (n =30 )先用“气管插管鉴定囊”检测 ,然后改用听诊法检测 ;Ⅱ组病人 (n =2 7)先用听诊法检测然后换用“气管插管鉴定囊”检测。结果 “气管插管鉴定囊”检测所需花费的时间短于听诊法 ;两法均检测出了全部 14例食管内插管病人 ;在 5 7例气管内插管病人中 ,“气管插管鉴定囊”正确检测出 5 3例气管内插管 (敏感性为92 98% ) ,听诊法检测出 4 6例气管内插管 (敏感性为 85 19% )。结论 用“气管插管鉴定囊”

Objective To compare the efficacy of tracheal detecting-bulb(TDB)and stethoscope in critically ill patients.Methods Fifty-seven patients with cardiac arrest were enrolled.After tracheal intubation and ETT cuff inflation in the emergency department,the patients were allocated randomly to two groups.In group 1(n=30),patients underwent a TDB test and an auscultation test in sequence.In group2(n=27),patients underwent an auscultation test and a TDB test in sequence.Results The TDB test was faster than the auscultation test;The TDB test and auscultation test indicated all fourteen esophageal intubations.In 57 tracheal intubations,the TDB test correctly indicated 53 tracheal intubations(sensitivity,92.98%).The ausculation test identified 46 tracheal intubations(sensitivity,85.19%).Conclusion The TDB is a valuable diagnostic tool for differentiating tracheal from esophageal intubation.
