Effect of bel canto in the respiratory rehabilitation of patients with chronic obstructive pulmonary disease in stable stage / 中国实用护理杂志

ABSTRACT

Objective:To investigate the effect of bel canto breathing training method on the respiratory rehabilitation of patients with chronic obstructive pulmonary disease in stable stage.Methods:Using a quasi-experimental research method, 40 patients with chronic obstructive pulmonary disease in stable stage from September to December 2018 in two wards (the first ward and the second ward) with the same level of diagnosis and treatment of respiratory physicians, nurses' nursing ability and the ward environment of the First Hospital of Lanzhou University were selected. The first ward was used as the experimental group, and the second ward was used as the control group, there were 20 cases in each group. The patients in the experimental group were given bel canto breathing training and conventional breathing training, while the patients in the control group were given conventional breathing training. A WeChat group was established, and training videos were distributed in the WeChat group after discharge to urge patients to perform training. After 3 months of intervention, the quality of life, anxiety, depression, and pulmonary function were evaluated by St George′s Respiratory Questionnaire (SGRQ), Hospital Anxiety and Depression Scale (HADS), proportion of forced expiratory volume in forced vital capacity in the first second(FEV1/FVC).Results:The SGRQ score, HADS score and FEV1/FVC value in the experimental group before intervention respectively were (41.35 ± 9.94), (16.55 ± 4.29) points and (47.13 ± 8.85)%, at discharge respectively were (28.95 ± 5.66), (11.20 ± 2.75) points and (59.51 ± 10.49)% and after three months of intervention respectively were (21.75 ± 6.31), (7.15 ± 3.51) points and (66.69 ± 7.87)%, while the SGRQ score, HADS score and FEV1/FVC value in the control group before the intervention respectively were (42.10 ± 10.50), (16.60 ± 4.73) points and (46.23 ± 10.14)%, at discharge respectively were (34.90 ± 10.16), (13.35 ± 2.37) points and (52.91 ± 7.86)%, and after three months of intervention (35.80 ± 7.27), (14.20 ± 5.05) points and (52.65 ± 8.60)%. With the increase of the intervention time of bel canto breathing training, the SGRQ score and HADS score decreased ( F=29.65, 17.44, both P<0.05), and the FEV1/FVC value increased ( F=27.38, P<0.05). Within-group comparisons the SGRQ score, HADS score, and FEV1/FVC value in the experimental group at discharge, three months after the intervention versus pre-intervention, and three months after the intervention versus discharge showed statistically significant differences ( t values were -7.73 - 7.38, all P<0.05). SGRQ score, HADS score, and FEV1/FVC value in the control group were only statistically significant at discharge versus pre-intervention ( t=-4.63, -2.79, 5.28, all P<0.05). The SGRQ, HADS score and FEV1/FVC value between the 2 groups were not statistically significant before the intervention, but statistically significant at discharge and three months after the intervention ( t values were -6.53 - 5.39, all P<0.05). Conclusions:Bel canto breathing training can improve the quality of life, reduce anxiety, depression and increase FEV1/FVC in patients with chronic obstructive pulmonary disease in stable stage.
