Objective To explore the value of ultrasonography in evaluating diaphragm function after respiratory function training in stroke patients.Methods 48 patients with respiratory dysfunction caused by their first ischemic or hemorrhagic stroke admitted to the First People's Hospital of Foshan from June 2019 to June 2022 were selected.All patients received 4 weeks of respiratory function training(RFT)in addition to conventional treatment.The pre-and post-RFT right diaphragmatic mobility(RDM)measured on ultrasound,partial pressure of oxygen(PaO2)and carbon dioxide(PaCO2)in blood-gas analysis,and the Acute Physiology and Chronic Health Evaluation Ⅱ(APACHE Ⅱ)were compared.Results The post-RFT DMs and PaO2 levels were significantly higher than that of pre-RFT(P＜0.001),and the PaCO2 levels and APACHE Ⅱ scores were significantly lower than that of pre-RFT(P＜0.001).Changes of DM positively correlated with changes of PaO2(r=0.715,P＜0.001),while negatively correlated with changes of PaCO2(r=-0.695,P＜0.001).There was no significant correlation between changes of RDM and changes of APACHE Ⅱ score(r=-0.229,P=0.187).Conclusion Diaphragm mobility measured on ultrasound can reflect diaphragm function non-invasively and efficiently,and can be used for clinical evaluation of diaphragm function.
