【摘要】 目的：探究呼吸肌訓练联合体位优化对脑梗死患者坠积性肺炎的预防效果。方法：选取2021年1—12月于九江市第三人民医院接受治疗的90例脑梗死患者，按照随机数字表法分为观察组与对照组，各45例。两组均进行常规护理干预，在此基础上，对照组进行早期康复训练联合传统体位干预，观察组进行呼吸肌训练联合体位优化干预。比较干预前后两组肺功能[用力肺活量(FVC)、第1秒用力呼气容积(FEV₁)及最大呼气流量(PEF)]、吞咽功能(洼田饮水试验)变化情况，统计两组住院期间坠积性肺炎发生情况。结果：干预后，两组FVC、FEV₁、PEF均高于干预前，观察组上述指标均高于对照组，差异均有统计学意义(P1) and peak expiratory flow (PEF)]， swallowing function (water swallow test) were compared between the two groups before and after the intervention， and the occurrence of hypostatic pneumonia during hospitalization was counted between the two groups. Result： After intervention， the FVC， FEV₁and PEF in the two groups were higher than those before intervention， and the above indicators in the observation group were higher than those in the control group ......
