We conducted a retrospective study of critical ill patients who used ECMO during their ICU stay. ICU-AW was diagnosed at the time when patients discharged and had a Medical Research Council (MRC) sum score < 48 out of a maximal score of 60. We divided patients to ICU-acquired weakness group and no ICU-acquired weakness group and compared their clinical characteristics. Baseline characteristics and therapy details were collected from the case report forms and inspection reports. Univariable analysis and logistic regression analysis were used to analyze clinical characteristics of individuals and to find risk factors of ICU-AW.
