Application of external diaphragm pacemaker combined with manual hyper inflation in pulmonary function rehabilitation of patients with cervical spinal cord injury after tracheotomy

目的探讨研究体外膈肌起搏器(EDP)联合人工膨肺技术(MHI)对颈髓损伤气管切开患者肺功能康复的应用效果。方法选取2021年4月至2022年4月于赣州市人民医院进行颈髓损伤气管切开治疗的50例患者作为研究对象,采用随机数字表法将其分为观察组(n=25)和对照组(n=25),对照组予以常规呼吸训练,观察组在对照组基础上联合EDP、MHI进行干预。比较两组患者治疗前后的肺功能变化。结果观察组治疗7、14、21、28 d的肺部感染评分均低于对照组,用力肺活量(FVC)水平均高于对照组,差异有统计学意义(P<0.05)。观察组治疗28 d的膈肌移动度、厚度均大于对照组,差异有统计学意义(P<0.05)。结论对于颈髓损伤气管切开患者,EDP联合MHI的应用能够有效改善患者肺功能,降低肺部感染风险,整体效果显著,值得推广。

Objective To investigate the application effect of external diaphragm pacemaker(EDP)combined with manual hyper inflation(MHI)in pulmonary function rehabilitation of patients with cervical spinal cord injury after tracheotomy.Methods A total of 50 patients with cervical spinal cord injury who underwent tracheotomy in the Ganzhou People's Hospital from April 2021 to April 2022 were selected as the research objects.They were divided into observation group(n=25)and control group(n=25)by random number table method.The control group was given routine breathing training,and the observation group was given EDP and MHI intervention on the basis of the control group.The changes of lung function before and after treatment were compared between the two groups.Results The pulmonary infection scores of the observation group 7,14,21 and 28 days after treatment were lower than those of the control group,and the levels of forced vital capacity(FVC)were higher than those of the control group,and the differences were statistically significant(P<0.05).The diaphragm mobility and thickness of the observation group were higher than those of the control group 28 days after treatment,and the differences were statistically significant(P<0.05).Conclusion For patients with cervical spinal cord injury after tracheotomy,the application of EDP combined with MHI can effectively improve the lung function of patients,reduce the risk of lung infection,and the overall effect is significant,which is worthy of promotion.
