一种新型抬颌辅助工具在无痛支气管镜操作中的应用

Effects of a new jaw lifting auxiliary tool in painless bronchoscopy operation

目的自行设计一种新型抬颌辅助工具,探讨其在无痛支气管镜操作中的应用效果。方法采用便利抽样法,于2023年1—12月选取嘉兴市第一医院内镜中心行无痛支气管镜检查的160例患者为研究对象;采用随机数字表法将研究对象分为试验组(n=80)和对照组(n=80)。在进行无痛支气管镜操作时,试验组采用新型抬颌辅助工具开放气道,对照组采用传统手工方法开放气道。比较两组不同时间点血氧饱和度情况和支气管镜通过声门时间。结果试验组不同时间点发生血氧饱和度<95%的例数少于对照组,差异具有统计学意义(均P<0.05)。试验组的支气管镜通过声门时间少于对照组,差异具有统计学意义[(2.86±0.69)s vs.(3.20±0.96)s,P<0.05]。结论在进行无痛支气管镜操作时,采用新型抬颌辅助工具可以预防患者发生血氧饱和度降低的情况,并缩短支气管镜通过声门的时间,未来可在临床实践中进一步推广、应用。

ObjectiveTo design a new jaw-lifting auxiliary tool and explore its effect in painless bronchoscopy.MethodsFrom January to December 2023,convenience sampling was used to select 160 patients who underwent painless bronchoscopy at the Endoscopy Center of the First Hospital of Jiaxing as subjects.The subjects were divided into an experimental group(n=80)and a control group(n=80)using a random number table method.During painless bronchoscopy,the experimental group used a new jaw-lifting auxiliary tool to open the airway,while the control group used traditional manual methods to open the airway.Two groups were compared patient oxygen saturation at different time points,and bronchoscopy passage time through the glottis.ResultsThe number of cases in which blood oxygen saturation<95%occurred at different time points in the experimental group was lower than that in the control group(all P<0.05).The time for bronchoscopy to pass through the glottis in the experimental group was shorter than that in the control group,and the difference was statistically significant[(2.86±0.69)s vs.(3.20±0.96)s,P<0.05].ConclusionsUsing a new jaw-lifting auxiliary tool during painless bronchoscopy can reduce the decreased oxygen saturation in patients and shorten the time for bronchoscopy to pass through the glottis.It can be further promoted and applied in clinical practice.
