排痰仪联合改良体位引流对卒中后肺部感染患者的应用效果研究

Clinical study on the combination of sputum expectorant and improved positional drainage for post-stroke pulmonary infection patients

目的:探讨排痰仪联合改良体位引流在卒中后长期卧床肺部感染患者中的应用效果。方法:按照随机数表法将医院收治的60例卒中后长期卧床肺部感染患者分为观察组(30例)和对照组(30例)。对照组采用人工拍背辅助排痰模式,在对照组基础上,观察组用排痰仪加改良体位引流,两组均连续干预2周。比较两组体征改善时间、住院时间、动脉血气分析指标、肺功能指标[用力肺活量(FVC)、第1 s用力呼气容积(FEV_(1))、FEV_(1)与FVC比值]和并发症发生率。结果:观察组患者体征改善时间和住院时间均短于对照组(P<0.05);与对照组相比,观察组患者干预后动脉血氧饱和度(SaO_(2))、动脉血氧分压(PaO_(2))指标较高,动脉血二氧化碳分压(PaCO_(2))指标较低(P<0.05);观察组患者干预后FVC、FEV_(1)及FEV_(1)/FVC指标高于对照组(P<0.05);观察组患者并发症发生率低于对照组(P<0.05)。结论:卒中后长期卧床肺部感染患者进行排痰仪联合改良体位引流干预可缩短症状体征改善时间和住院时间,利于改善患者动脉血气指标和肺功能,降低患者并发症发生率。

Objective:To explore the application effect of sputum expectorant combined with improved positional drainage in patients with long-term bedridden pulmonary infection after stroke.Method:According to the random number table method,60 patients with long-term bedridden pulmonary infection after stroke admitted to the hospital were divided into an observation group(30 cases)and a control group(30 cases).The control group was treated with manual back patting assisted sputum drainage mode.On the basis of the control group,the observation group was treated with sputum drainage instrument and improved position drainage.Both groups received continuous intervention for 2 weeks.Compare the improvement time of physical signs,length of hospital stay,arterial blood gas analysis indicators,lung function indicators[forced vital capacity(FVC),forced expiratory volume in one second(FEV_(1)),FEV_(1) to FVC ratio],and incidence of complications between two groups.Result:Compared with the control group,the observation group had a shorter time for improvement in physical signs and hospitalization time(P<0.05);Compared with the control group,the observation group had higher arterial oxygen saturation(SaO_(2))and arterial partial pressure of oxygen(PaO_(2))indicators and lower arterial partial pressure of carbon dioxide(PaCO_(2))indicators after intervention(P<0.05);Compared with the control group,the observation group had higher FVC,FEV_(1),and FEV_(1)/FVC indicators after intervention(P<0.05);Compared with the control group,the incidence of complications in the observation group was lower(P<0.05).Conclusion:Long term bedridden pulmonary infection patients after stroke can be treated with sputum expectorants combined with improved positional drainage intervention,which can shorten the time for symptom and sign improvement and hospital stay,improve arterial blood gas indicators and lung function,and reduce the incidence of complications in patients.
