目的观察喉镜在经皮扩张气管切开手术中的临床应用和效果。方法 70例患者随机分为2组:喉镜辅助组(喉镜组)36例在气管切开前应用喉镜直视下将气管插管退至声门口,常规组34例则不应用喉镜。观察2组患者的手术时间、出血量、并发症情况。结果喉镜组的手术时间为(6.1±1.7)min,明显短于常规组〔(7.5±2.5)min〕;喉镜组发生缺氧事件0例,常规组8例,2组发生率比较,差异有统计学意义(P<0.05);喉镜组出血量为(2.1±0.5)ml,少于常规组〔(3.1±0.7)ml〕,但差异无统计学意义(P>0.05);喉镜组发生误吸0例,常规组误吸2例。结论喉镜辅助经皮扩张气管切开手术适合在ICU气管切开时常规应用。
Objective To observe the clinical application and effect of laryngoscope in percutaneous dilation tracheotomy. Methods Seventy patients were randomly divided into two groups: the laryngoscope-assisted group (laryngoscope group), 36 patients underwent tracheotomy with tracheotomy and the endotracheal intubation was retreated to the glottis opening. The conventional group of 34 patients did not use the laryngoscope . Two groups of patients were observed operation time, bleeding, complications. Results The operation time of the laryngoscope group was (6.1 ± 1.7) min, which was significantly shorter than that of the conventional group (7.5 ± 2.5 min). There was no hypoxia in the laryngoscope group, The difference was statistically significant (P <0.05). The amount of bleeding in the laryngoscope group was (2.1 ± 0.5) ml less than that in the conventional group (3.1 ± 0.7) ml, but the difference was not statistically significant (P> 0.05) Aspiration occurred in the mirror group 0 cases, conventional group aspiration 2 cases. Conclusion The laryngoscope assisted percutaneous dilation and tracheostomy is suitable for tracheostomy in ICU.
