Abstract:
Objective:To explore the influence of Passy-Muir speaking valve(PMV)on diaphragm function by using ultra-sound in stroke patients with tracheotomy and to evaluate the application value of improving respiratory func-tion by using ultrasonography parameters of diaphragm in PMV therapy.Method:Ninety stroke patients with tracheotomy meeting the inclusion criteria were randomly divided into PMV group(n=45)and control group(n=45).The control group received traditional respiratory therapy.The PMV group underwent PMV therapy based on traditional respiratory therapy.The procedure was 60min/day,6days/week for 2 weeks.The scores of Borg scale,end-expiratory diaphragm thickness(EDT),end-inspiration diaphragm thick-ness(IDT),diaphragm thickening fraction(DTF)and diaphragm mobility were assessed before and after treatment.The correlation of the scores of Borg scale and diaphragm ultrasonographic parameters were analyzed.Result:After two weeks of treatment,significant improvements were observed within both groups:Borg scores decreased(P<0.05),while EDT,IDT,DTF,and diaphragm mobility increased(P<0.05).Compared with control group,FMV group had significantly greater improvement on the scores of Borg(P<0.05),EDT(P<0.05),IDT(P<0.05),DTF(P<0.05)and diaphragm mobility(P<0.05).In the PMV group,post-treatment Borg scores were significantly negatively correlated with EDT(r=﹣0.962,P<0.01)、IDT(r=﹣0.948,P<0.01)、DTF(r=﹣0.972,P<0.01)and diaphragm mobility(r=﹣0.960,P<0.01).Conclusion:PMV can improve respiratory function,increase the mobility of diaphragm and improve pulmonary function in stroke tracheotomy patients.Diaphragm ultrasonographic parameters can predict the degree of dys-pnea to provide the following rehabilitation with ultrasonography evidence.
