Objective:The purpose of this study was to observe the influence of Oscillatory Positive Expiratory Pressure to the Sputum Expectoration and Pulmonary Function of Patients of Acute Exacerbation of Chronic Obstructive Pulmonary Disease(AECOPD)as well as to the clinical symptoms.Methods:We selected 120 patients who were diagnosed of AECOPD and accepted meidicine treatment in our hospital from September 2016 to March 2017,83 of them were male and 37 were female.They were aged 47 to 96 years,and all conformed to the diagnosis of COPD in 2016 GOLD guide and the definition of acute exacerbation in guide.The patients were divided into treatment group and control group for 60 patients randomly,and all of them were gave the routine treatment of antiasthma,relieving cough,reducing sputum and anti-infection.The treatment group also use oscillatory positive expiratory pressure to assist sputum expectoration for seven days.Observe the two groups1.Variant of volume of sputum in every 24 hours,the colour and viscosity of their sputum from day one to day seven.2.Variant of pulmonary function before and after treatment,recording the values of forced expired volume in one second(FEV1)and forced expired volume in one second percentage of expected value(FEV1%pred).3.Variant of the CAT and TDI questionnaire and score,to evaluate the improvement of patients' clinical symptoms before and after treatment.At the last,use SPSS 16.0 to put all the values to calculate and conduct statistical analysis.Results:1.The average volum of sputum in 24 hours in the treatment group from day one to day three increased apparently compared to the control group,the colour score and viscosity of sputum decreased apparently in day three compared to the control group.(P<0.05).2.The pulmonary function(FEV1?FEV1%pred)increased apparently in day3 compared to the control group(P<0.05).3.The CAT decreased and TDI increased apparently compared to the control group(P<0.05).Conclusions:1.OPEP can help the patients of AECOPD to excrete sputum effectively2.OPEP is beneficial to the pulmonary function of AECOPD3.OPEP is helpful to improve clinical symptoms of AECOPD... |
