Effect of mechanical vibration sputum expectoration in the adjuvant treatment of stroke-associated pneumonia

Objective To investigate the effect of mechanical vibration sputum expectoration in the adjuvant treatment of stroke-associated pneumonia. Methods Totally 60 patients with stroke-associated pneumonia were divided into control group (n=30)and study group(n=30) according to the arrival sequences of hospital admission. All patients received anti-infective therapy for stroke-associated pneumonia. The routine hand-assisted percussion on the back was adopted in the control group, while the mechanical vibration sputum expectoration was carried out in the study group. The clinical symptoms and clinical pulmonary infection scores of the two groups were observed at one week after intervention. Results The overall response rate of treatment was 96. 67%(29/30)in the study group, which was higher than 80. 00%(24/30)in the control group (P＜0. 05). Patients in the study group had a higher volume of sputum expectoration and shorter time to moist rale disappear compared with those in the control group (P＜0. 01). Patients in the study group achieved better outcomes of respiratory rate, SaO 2 and PaO 2 compared with those in the control group (P＜0. 01). Conclusion Application of mechanical vibration sputum expectoration is potentially effective to improve the condition of patients and enhance the treatment efficacy of stroke-associated pneumonia.
