To review the evidence about inspiratory muscle training (IMT) in patients in postoperative of cardiac surgery. We conducted this systematic review used the databases Ovid, LILACS, CINAHL, PubMed, PEDro, and CENTRAL. Randomized clinical trials that addressed IMT after cardiac surgery were selected. The outcomes assessed were maximum inspiratory pressure (MIP), maximum expiratory pressure (MEP), tidal volume (TV), peak expiratory flow (PEF), functional capacity (6-minute walk test) and length of hospital stay. The mean difference between groups and the respective 95% confidence interval (CI) were calculated and used to quantify the effect of continuous outcomes. Seven studies were selected. The IMT was superior to the control over MIP 15.77 cmH2O (95% CI, 5.95-25.49), MEP 15.87 cmH2O (95% CI, 1.16-30.58), PEF 40.98 L/min (95% CI, 4.64-77.32), TV 184.75 mL (95% CI, 19.72-349.77), hospital stay -1.25 days (95% CI, -1.77 to -0.72), but without impact on functional capacity 29.93 m (95% CI, -27.59 to 87.45). Based on the results presented, IMT was beneficial as a form of treatment for patients after cardiac surgery.
为了回顾关于心脏手术后患者进行吸气肌训练（IMT）的证据。我们使用Ovid、LILACS、CINAHL、PubMed、PEDro和CENTRAL数据库进行了这项系统评价。选取了涉及心脏手术后IMT的随机临床试验。评估的结果包括最大吸气压力（MIP）、最大呼气压力（MEP）、潮气量（TV）、呼气峰值流速（PEF）、功能能力（6分钟步行试验）和住院时间。计算了组间平均差异和相应的95%置信区间（CI），并用于量化连续性结果的效应。共选取了7项研究。IMT在MIP方面比对照组高15.77 cmH2O（95%CI，5.95 - 25.49），MEP高15.87 cmH2O（95%CI，1.16 - 30.58），PEF高40.98 L/min（95%CI，4.64 - 77.32），TV高184.75 mL（95%CI，19.72 - 349.77），住院时间缩短-1.25天（95%CI，-1.77至-0.72），但对功能能力无影响，相差29.93 m（95%CI，-27.59至87.45）。根据所呈现的结果，IMT作为心脏手术后患者的一种治疗形式是有益的。
