目的观察多频振动排痰仪在老年慢性阻塞性肺疾病(COPD)患者中的应用效果。方法选取2015年1月—2016年5月宝鸡市中心医院收治的老年COPD患者60例,根据排痰方法分为对照组和观察组,每组30例。对照组患者采用人工叩背排痰,观察组患者采用多频振动排痰仪机械排痰。比较两组患者疗效指标(24 h排痰量、体温恢复正常时间、血常规恢复正常时间及住院时间)、肺功能指标〔用力肺活量(FVC)、第1秒用力呼气容积(FEV1)、FEV1占预计值百分比(FEV1%)〕及并发症发生情况。结果观察组患者24 h排痰量多于对照组,体温恢复正常时间、血常规恢复正常时间及住院时间短于对照组(P<0.05)。观察组患者FVC、FEV1及FEV1%高于对照组(P<0.05)。观察组患者并发症发生率低于对照组(P<0.05)。结论多频振动排痰仪在老年COPD患者中的应用良好,可有效促进患者排痰及改善患者肺功能。
Objective To observe the effect of multi-frequency vibro-spittoon in senile patients with chronic obstructive pulmonary disease (COPD). Methods From January 2015 to May 2016, 60 elderly COPD patients were enrolled in the Central Hospital of Baoji. According to the expectoration method, the patients were divided into control group and observation group, with 30 cases in each group. Patients in the control group were treated with manual knock-back phlegm, and those in the observation group were given mechanical phlegm by multi-frequency vibration sputum sputum. Efficacy indicators (24 h sputum volume, body temperature recovery time, blood routine recovery time and hospital stay), lung function index (forced vital capacity (FVC), forced expiratory volume 1 second (FEV1), FEV1 Accounting for the predicted percentage (FEV1%)] and the incidence of complications. Results The sputum volume of observation group was higher than that of control group in 24 h. The time of normal body temperature recovery, the time of normal blood routine recovery and hospital stay were shorter than those of control group (P <0.05). FVC, FEV1 and FEV1% in the observation group were higher than those in the control group (P <0.05). The complication rate in observation group was lower than that in control group (P <0.05). Conclusions The multi-frequency vibro-phlegm-descending sputum instrument has a good application in elderly COPD patients, which can effectively promote sputum aspiration and improve pulmonary function in patients.
