早期床旁运动干预在心脏手术后患者心脏康复中的应用效果

Early exercise intervention at the bedside in patients undergoing cardiac rehabilitation after cardiac surgery

目的评估早期床旁运动干预对心脏瓣膜手术后患者康复的影响。方法纳入40例心脏瓣膜疾病患者,其中20例患者[(49.05±3.728)岁]术后第3、4、5天接受床旁运动干预(3 min/d,干预组),其余20例患者[(47.95±3.214)岁]未接受床旁运动干预(对照组)。术前进行心理教育,并通过标准化问卷简表对患者单独评估。通过指脉氧仪及6 min步行距离来评估心脏康复效果。结果干预组心脏瓣膜患者术后3 d的SpO_(2)水平高于对照组(P<0.05)。干预组术后5 d心率降至基线水平,低于对照组(P<0.05)。结论初级床旁运动(3 min/d)可以提高SpO_(2)、降低心率,进而改善患者基线状态,促进患者康复。

Objective To evaluate the effects of early exercise intervention in patients who have undergone primary isolated valve surgery.Methods Forty patients scheduled for mitral,aortic,and/or tricuspid valve surgery were allocated to receive a supervised exercise intervention consisting of cycling for 3 min/d at the bedside after operation(intervention group,n=20,mean age[49.05±3.728]years)or to receive no exercise intervention(control group,n=20,mean age[47.95±3.214]years).Oxygen saturation(SpO_(2))was measured by pulse oximetry continuously before and after the 6-minute walk test.Psychoeducational counseling was provided,and patients were assessed using standard patient questionnaires.Results The arterial SpO_(2)level increased significantly in the intervention group after exercise compared with the control group(P<0.05).Heart rate returned to baseline in the intervention group postoperatively and was significantly lower than that in the control group(P<0.05).Conclusions A small amount of supervised cycling exercise at the bedside is a safe activity that may improve peripheral arterial SpO_(2)and reduce heart rate to the baseline level following longer distance walk before discharge in patients who have undergone isolated valve surgery.
