特制双导管结构在使用换管器更换气管导管中的应用价值

Application value of the novel double setup endotracheal tube on tracheal tube exchange with an airway exchange catheter

目的:探讨特制双导管结构在使用换管器更换气管导管过程中的应用价值。方法:选取60例围麻醉期需要更换气管导管的患者为研究对象,根据使用换管器不同分为对照组和试验组,每组各30例。对照组采用常规气管导管换管;试验组采用特制双导管换管。比较两组患者换管指标[一次插管成功率、插管时间、换管器折痕发生率、术后24 h咽痛(VAS评分)、声嘶发生情况]、换管过程中血流动力学[平均动脉压(MAP)、心率(HR)]及不良事件发生情况。结果:试验组患者换管一次插管成功率高于对照组(P<0.05);插管时间短于对照组(P<0.05);换管器折痕发生率低于对照组(P<0.05)。术后24 h,试验组患者咽痛VAS评分低于对照组(P<0.05);两组患者声嘶发生率无统计学差异(P>0.05)。两组患者在换管过程的MAP、HR比较,差异无统计学意义(P>0.05),且均无低氧血症等不良事件发生。结论:特制双导管结构能提高换管器换管一次性成功率,减少换管时间和并发症的发生。

Objective:To explore the application value of the novel double setup endotracheal tube(ETT)on tracheal tube exchange with an airway exchange catheter(AEC).Methods:60 patients who needed to replace tracheal tube during the perioperative period were selected as the research subjects.They were divided into a control group and an experimental group based on the use of different tracheal tube,with 30 cases in each group.The control group treated with a single ETT,and the experimental group treated with double setup ETT.The indicators of tube replacement[success rate of intubation,intubation time,incidence of catheter creases,24-hour postoperative pharyngeal pain(VAS score),occurrence of hoarseness],hemodynamics during intubation process[mean arterial pressure(MAP),heart rate(HR)],and incidence of adverse events were compared between two groups.Results:The success rate of intubation on the first attempt in experimental group was greater than that in control group(P<0.05),the intubation time was shorter than that in control group(P<0.05),and the incidence of catheter creases was lower than that in control group(P<0.05).24 hours after surgery,the VAS score of pharyngeal pain in the experimental group was lower than that in the control group(P<0.05).There was no statistically significant difference in the incidence of hoarseness between the two groups(P>0.05).There was no statistically significant difference in MAP and HR between the two groups of patients during tube replacement(P>0.05),and there were no adverse events such as hypoxemia in either group.Conclusion:The novel double setup tube can improve the intubation success rate at the first attempt,reduce the time and adverse events during the process of tracheal tube exchange.
