To determine the effect of inspiratory muscle training (IMT) on pulmonary function, respiratory muscle strength (RMS), and functional capacity in patients undergoing cardiac surgery. The PubMed, PEDro, CINAHL, Web of Science, CENTRAL, and EMBASE databases were searched from inception to June 2020. Randomized controlled trials (RCTs) that evaluated patients who underwent cardiac surgery were included in this review. Meta-analysis performed using a random-effects model showed that the mean difference in forced vital capacity, forced expiratory volume in 1 second, 6-minute walk distance, and RMS was 3.47% (95% confidence interval [CI], 0.57 to 6.36), 5.80% (95% CI, 2.03 to 9.56), 78.05 m (95% CI, 60.92 to 95.18), and 4.8 cmH2O (95% CI, -4.00 to 13.4), respectively. There is strong evidence that IMT improves inspiratory muscle strength, pulmonary function, and functional capacity, and reduces the length of hospital stay in patients undergoing cardiac surgery.
为确定吸气肌训练（IMT）对心脏手术患者肺功能、呼吸肌力量（RMS）和功能能力的影响。检索了PubMed、PEDro、CINAHL、Web of Science、CENTRAL和EMBASE数据库，检索时间从建库至2020年6月。本综述纳入了评估心脏手术患者的随机对照试验（RCT）。采用随机效应模型进行的荟萃分析表明，用力肺活量、第1秒用力呼气量、6分钟步行距离和RMS的平均差异分别为3.47%（95%置信区间[CI]，0.57至6.36）、5.80%（95%CI，2.03至9.56）、78.05米（95%CI，60.92至95.18）和4.8厘米水柱（95%CI，-4.00至13.4）。有强有力的证据表明，IMT可改善心脏手术患者的吸气肌力量、肺功能和功能能力，并缩短住院时间。
