气管插管患者行经皮扩张气管切开术的安全性研究

Security Research of Percutaneous Dilational Tracheostomy on Intubated Patients

目的研究气管插管患者行经皮扩张气管切开术的安全性。方法将121例经口气管插管患者随机分成对照组59例,观察组62例。两组患者均行经皮扩张气管切开术,对照组按常规方法于局麻前将气管插管拔出至门齿18～20cm处,观察组在经皮扩张完气管前壁后将气管插管全部拔出。结果两组患者手术操作时间、出血量比较差异均无统计学意义(P>0.05);气管插管意外脱出发生率比较,对照组高于观察组,差异有统计学意义(P<0.05)。结论在扩张气管前壁后拔出气管插管更有利于患者安全。

Objective To explore the security of percutaneous dilational tracheostomy on intubated patients.Methods Total of 121 orotracheal intubatd patients were randomly divided into control group（59 patients） and observation group（62 patients）.They all accepted the percutaneous dilational tracheostomy.According to the routine method tracheal intubation was pulled out 18~20 cm to the incisor teeth before local anesthesia in control group.While in observation group tracheal intubation was pulled out after the tracheal anterior wall was expanded.Results The operation time and the amount of blood loss had no significant difference between the two groups（P〉0.05）.The incidence that tracheal intubation was accidentally pulled out was higher in control group than in observation group.The differences were statistically significant（P〈0.05）.Conclusion It’s more conducive to patient safety that tracheal intubation was pulled out after the tracheal anterior wall was expanded.
