| Objective: To observe the effects of external diaphragm pacemaker (EDP) and electric rising bed on pulmonary function in patients with post-stroke tracheotomy and evaluate the clinical efficacy. Methods: All 60 patients with post-stroke tracheotomy were selected and divided into control group and observation group with 30 patients in each group according to a random number table. The control group was treated with electric standing bed on the basis of conventional drug therapy and nursing, and the observation group was treated with EDP on the basis of the control group. Both groups were treated for 4 weeks. Blood gas analysis index (PaO2, PaCO2), diaphragm mobile degrees (diaphragmatic excursion, DE), clinical pulmonary infection score (CPIS) and the effective rate of clinical symptom improvement were compared between two groups. Results: After 1 month of treatment, PaO2 in control group and observation group was higher than that before treatment (P<0.05), while PaCO2 in control group and observation group was lower than before treatment (P<0.05). After 1 month of treatment, PaO2 in the observation group was higher than that in the control group (P<0.05), but there was no significant difference in PaCO2 between the two groups (P>0.05). After 1 month of treatment, DE in control group and observation group was higher and CPIS was lower than before treatment (P<0.05). After 1 month of treatment, DE in the observation group was higher and CPIS was lower than in the control group (P<0.05). The total effective rate of the observation group was higher than that of the control group (P<0.05). Conclusion: In vivo EDP combined with electric standing bed can effectively improve the blood gas analysis index of patients with tracheotomy after stroke, improve the damaged diaphragm function, reduce lung infection, and improve the clinical efficiency. |
