电子支气管镜吸痰在下呼吸道感染患者治疗中的应用

Application of Electronic Bronchoscope for Sputum Suction in the Treatment of Patients with Lower Respiratory Tract Infection

目的研究在下呼吸道感染患者治疗中应用电子支气管镜吸痰的临床效果。方法方便选取2019年1月—2021年1月68例下呼吸道感染患者,将其按照数字随机表法予以分组,每组34例。对照组实施常规治疗,研究组在常规治疗基础上实施电子支气管镜吸痰治疗,对比分析两组临床效果。结果研究组总有效率(94.12%)高于对照组,差异有统计学意义(χ^(2)=4.221,P=0.040);治疗前组间呼吸力学指标对比差异无统计学意义(P﹥0.05),治疗后研究组肺总量、最大通气量、最大呼气中期流量、第一秒用力呼气容积比对照组高,差异有统计学意义(P<0.05);治疗前组间血清炎性因子指标对比差异无统计学意义(P﹥0.05),治疗后研究组降钙素原、C反应蛋白、外周白细胞计数均低于对照组,差异有统计学意义(P<0.05);治疗前组间血气分析指标对比差异无统计学意义(P﹥0.05),治疗后研究组氧饱和度、氧分压高于对照组,二氧化碳分压低于对照组,差异有统计学意义(P<0.05)。研究组严重紫绀、窦性心动过速、血氧饱和度降低等不良反应总发生率低于对照组,差异有统计学意义(P<0.05)。结论电子支气管镜吸痰治疗可以促进下呼吸道感染患者呼吸功能改善,减轻炎症反应,使患者血气分析指标得到改善,避免不良反应发生,临床价值显著。

Objective To study the clinical effect of electronic bronchoscope for sputum suction in the treatment of patients with lower respiratory tract infection.Methods From January 2019 to January 2021,68 patients with lower respiratory tract infection were conveniently selected.They were divided into groups according to the number random table method,with 34 cases in each group.The control group received conventional treatment,and the study group performed electronic bronchoscopy on the basis of conventional treatment.The clinical effects of the two groups were compared and analyzed.Results The total effective rate(94.12%)of the study group was higher than that of the control group,and the difference was statistically significant(χ^(2)=4.221,P=0.040).There was no statistically significant difference in the respiratory mechanics index between the groups before treatment(P>0.05).After treatment,the total lung volume,maximum ventilation volume,mid-maximum expiratory flow,and forced expiratory volume in the first second of the study group were higher than those of the control group,and the difference was statistically significant(P<0.05).There was no statistically significant difference in serum inflammatory factors between the groups before treatment(P>0.05).After treatment,the counts of procalcitonin,C-reactive protein and peripheral white blood cells in the study group were lower than those in the control group,and the difference was statistically significant(P<0.05).There was no statistically significant difference in the comparison of blood gas analysis indexes between the groups before treatment(P>0.05).After treatment,the oxygen saturation and oxygen partial pressure of the study group were higher than those of the control group,and the carbon dioxide partial pressure was lower than that of the control group,the difference was statistically significant(P<0.05).The total incidence of adverse reactions such as severe cyanosis,sinus tachycardia,and decreased blood oxygen saturation in the study group was lower than that in the control group,and the difference was statistically significant(P<0.05).Conclusion Electronic bronchoscopy can promote the improvement of patients with lower respiratory trout infection respiratory function,and reduce inflammation.Improve the patient's blood gas analysis index,avoid the occurrence of adverse reactions,and have significant clinical value.
