摘要
目的探讨超声膈肌功能评估与慢性阻塞性肺疾病(COPD)伴Ⅱ型呼吸衰竭患者机械通气间的关系.方法该研究选取2022年1月-2023年12月在固原市人民医院重症监护室住院治疗的COPD伴Ⅱ型呼吸衰竭进行机械通气患者作为研究对象,按照撤机结局将所有患者分为撤机成功组(62例)和撤机失败组(22例),对临床资料进行分析.结果撤机成功组患者各时间点膈肌位移、DTF显著高于撤机失败组(P<0.05),膈肌收缩速度显著低于撤机失败组(P<0.05).撤机前两组PaCO_(2)、PaO_(2)、pH值比较,差异不显著(P>0.05),撤机时两组患者PaCO_(2)、PaO_(2)、pH值均得到显著改善(P<0.05),且撤机成功组患者PaCO_(2)、PaO_(2)、pH值显著优于撤机失败组(P<0.05).撤机成功组患者生活质量显著高于撤机失败组(P<0.05).结论超声膈肌功能评估可用于指导临床对COPD伴Ⅱ型呼吸衰竭机械通气患者撤机时机的选择.
Objective To investigate the relationship between ultrasonic assessment of diaphragm function and mechanical ventilation in COPD patients with typeⅡrespiratory failure.Methods This study selected the COPD patients with typeⅡrespiratory failure who were hospitalized and received mechanical ventilation in our intensive-care unit from January 2022 to December 2023,according to the outcome of weaning,all patients were divided into weaning success group(62 cases)and weaning failure group(22 cases).Results The diaphragmatic displacement and DTF were significantly higher in the weaning success group than in the weaning failure group(P<0.05),and the diaphragmatic contraction velocity was significantly lower than in the weaning failure group(P<0.05).There was no significant difference in PaCO_(2),PaO_(2) and pH between the two groups before weaning(P>0.05).When weaning,PaCO_(2),PaO_(2) and pH in both groups were significantly improved(P<0.05),PaCO_(2),PaO_(2) and pH in the weaning success group were significantly better than those in weaning failure group(P<0.05).The quality of life in the weaning success group was significantly higher than that in the weaning failure group(P<0.05).Conclusion The evaluation of diaphragmatic function by ultrasonography can be used to guide the choice of weaning time in COPD patients with typeⅡrespiratory failure.
