床旁超声在脓毒症患者ICU获得性衰弱中的应用价值

Application value of bedside ultrasound in ICU acquired frailty in patients with sepsis

目的:比较床旁超声测量脓毒症患者股直肌横截面积和肌力运动功能之间的关系,判断肌肉变化对ICU获得性衰弱(ICU-AW)的诊断价值。方法:床旁超声测量脓毒症患者入组第1 d,第3 d,第5 d和转出ICU时股直肌横截面积,MRC肌力评分和手握式测力仪测量患者握力。结果:在37名ICU脓毒症住院患者中,股直肌横截面积和MRC肌力评分呈正相关,相关系数为0.462(P<0.05),股直肌横截面积变化率与MRC肌力评分呈显著负相关,r值为-0.662(P<0.05)。结论:床旁超声测量脓毒症患者骨骼肌减少和肌力下降有相关性,可以用于评价脓毒症患者ICU获得性衰弱。

Objective:To compare the relationship between bedside ultrasound measurement of rectus femoris cross-sectional area and muscle motor function in patients with sepsis,and to determine the diagnostic value of muscle changes for ICU acquired weakness(ICU-AW).Methods:Bedside ultrasound was used to measure the rectus femoris cross-sectional area,MRC muscle strength score and grip strength of patients with sepsis on day 1,3,and 5,and on day 5 of admission to the ICU.Results:In 37 patients with sepsis in ICU,the cross-sectional area of rectus femoris was positively correlated with MRC muscle strength score and the correlation coefficient was 0.462(P<0.05).The change rate of cross-sectional area of rectus femoris was significantly negatively correlated with MRC muscle strength score and r value was-0.662(P<0.05).Conclusion:Bedside ultrasound measurement of sarcopenia and muscle weakness in patients with sepsis is correlated,and it can be used to evaluate ICU-AW in patients with sepsis.
