Effect of sitting and lying Liuzijue for lung rehabilitation in acute exacerbation of chronic obstructive pulmonary disease patients with non-invasive ventilation: Study protocol for a randomized controlled trial.

INTRODUCTION

Chronic obstructive pulmonary disease (COPD) is a lung disease with the highest incidence and high mortality in the world. Acute exacerbation of chronic obstructive pulmonary disease (AECOPD) can significantly accelerate the progression of the disease. Pulmonary rehabilitation is one of the effective treatment methods in COPD patients, but few studies have focused on the effect of pulmonary rehabilitation in AECOPD patients. Liuzijue can improve the pulmonary function and relieve symptoms of COPD patients. However, due to the influence of disease and non-invasive ventilation (NIV), AECOPD patients have poor compliance with getting out of bed at the early stage. Sitting and lying Liuzijue is more suitable in AECOPD patients with NIV. Therefore, this study will evaluate the effect of sitting and lying Liuzijue for lung function, exercise endurance, and quality of life in AEOPD patients with NIV.

METHODS

This study is a clinical randomized controlled trial. Sixty four AECOPD patients with NIV will be randomly divided into the experimental group and the control group. All participants will be treated with routine treatment and nursing according to their specific condition. The experimental group will be combined with sitting and lying Liuzijue on the basis of the control group. The duration of the exercise will be 3 months. The primary outcomes are the pulmonary function test and 6-minute walking test (6MWT). The secondary outcome measures include blood gas parameters, dyspnea index (the Modified Medical Research Council Dyspnea Scale [mMRC]), the body-mass, airflow obstruction, dyspnea and exercise capacity (BODE) index, anxiety, and depression (Hospital Anxiety and Depression Scale [HADS]), and quality of life (St·George Respiratory Questionnaire [SGRQ]). The measurement of outcomes will be evaluated at week 13.

DISCUSSION

It's imperative to focus on pulmonary rehabilitation in AECOPD patients. The purpose of this study is to evaluate the effect of sitting and lying Liuzijue for pulmonary rehabilitation in AECOPD patients with NIV.
