下肢运动方式对COPD有创机械通气患者肌力的影响

Influence of Lower Limb Movement on Muscle Strength of COPD Patients with Invasive Mechanical Ventilation

为了比较运动方式对COPD有创机械通气患者肌力的影响,对入住ICU的112例COPD有创机械通气患者进行分组对照实验.按预设的早期运动方案,两组患者下肢运动方式不一样,干预组采用床上脚踏车进行下肢运动,对照组采用手动下肢运动.结果表明,脱离ICU监护时下肢主、客观肌力指标、ICU活动水平和Barthel指数评分以及出院时Barthel指数评分,两组患者之间差异有统计学意义(P<0.05),脱离ICU监护时上肢主、客观肌力指标和出院6个月Barthel指数,两组患者之间差异无统计学意义(P>0.05),说明COPD有创机械通气患者实施床上脚踏车运动安全可行,且可以改善下肢肌力和运动水平,促进日常生活功能的恢复.

To compare the influences of exercise modes on COPD patients with invasive mechanical ventilation,a group controlled experiment were conducted among 112 COPD patients who stayed in ICU.According to the predetermined proposals,two groups of patients took different lower limb movement.The intervention group performed in-bed bicycle exercise;while the control group performed traditional in-bed exercise.The results indicated that there were significant differences between the two groups(P<0.05)in subjective and objective indicators of muscle strength of the lower limbs,ICU activity level,and Barthel index scores when patients left ICU and when they were discharged from hospital respectively.There were no significant differences in upper limb muscle strength measured either by electronic grip gauge or MRC scale between two groups(P>0.05).There was no significant difference in Barthel index score measured in the first six months after discharge(P>0.05).The results show that early in-bed bicycle exercise is secure and workable for COPD patients with invasive mechanical ventilation,which can improve lower limb muscle strength and mobility and promote recovery of daily life function.
