Abstract

Aim: This study aimed to evaluate the effects of inspiratory muscle training on inspiratory muscle strength and cardiorespiratory performance in patients undergoing open heart surgery.

Method: This study was conducted as a randomized controlled trial with two groups. Fifty-eight patients who underwent open heart surgery were randomly assigned to either the intervention group or the control group 29 in the control group and 29 in the intervention group. Patients in the intervention group participated in a physical therapy program combined with inspiratory muscle training using the Thammasat University (TU) Breath Trainer. Patients in the control group received only the standard physical therapy program. The maximum inspiratory pressure, maximum expiratory pressure and 6 min walk test distance were assessed both before surgery and prior to hospital discharge.

Results: The intervention group had a significant increase in maximum inspiratory pressure (p < 0.001), maximum expiratory pressure (p < 0.001) and 6 min walk test distance (p = 0.013). The control group had a significant decrease in maximum inspiratory pressure (p < 0.001), maximum expiratory pressure (p = 0.002) and 6 min walk test distance (p < 0.001).

Conclusions: Inspiratory muscle training can be performed using maximum pressure resistors, such as the TU-Breath Trainer device. This training has been shown to effectively improve inspiratory muscle strength and cardiorespiratory performance in patients undergoing open heart surgery, as well as reduce pulmonary complications and shorten the length of hospital stay.

吸气肌训练改善心脏直视手术患者的心肺功能：一项随机对照试验。

目的：本研究旨在评价吸气肌训练对心脏直视手术患者吸气肌力量和心肺功能的影响。方法：采用随机对照试验，分为两组。58名接受心脏直视手术的患者被随机分为干预组和对照组，对照组29人，干预组29人。干预组的患者使用法政大学（TU）呼吸训练器进行物理治疗和吸气肌训练。对照组患者仅接受标准的物理治疗方案。在手术前和出院前评估最大吸气压、最大呼气压和6分钟步行测试距离。结果：干预组最大吸气压力（p < 0.001）、最大呼气压力（p < 0.001）、6 min步行测试距离（p = 0.013）均显著升高。对照组患者最大吸气压力（p < 0.001）、最大呼气压力（p = 0.002）和6 min步行测试距离（p < 0.001）均显著降低。结论：吸气肌训练可以使用最大压力电阻器进行，如TU-Breath Trainer装置。这种训练已被证明可以有效地改善心脏直视手术患者的吸气肌力量和心肺功能，减少肺部并发症，缩短住院时间。
