Abstract:

Objective To explore the effect of personalized early mobilization intervention on muscle strength ofpatients with mechanical ventilation at different time points. MethodsFrom October 2018 to July 2019, 80 ICUpatients who received mechanical ventilation at a tertiary hospital in Ningxia were selected and divided into twogroups according to the division of ICU ward. There were 40 patients in the intervention group and 40 patients inthe control group. The intervention group was given personalized early mobilization intervention , while the controlgroup received ICU routine early mobilization nursing. The general data of the patients, the Medical Research Council (MRC) Score , the incidence of ICU acquired weakness , B arthel Index,ICU mechanical ventilation time,length of ICU stay and other indicators were evaluated at different time points. R esultsOne case in the intervention group declined the study,39 cases finished the study in the intervention group and 40 cases in the controlgroup. There was no significant difference in general data between the two groups when entering ICU , but therewere significant differences in M RC score , incidence of ICU acquired weakness , mechanical ventilation time and length of ICU stay within the group and between the two groups. The results of repeated measures analysis of variance showed that there were significant differences in time effct and inter-group effect for MRC score, and therewere interactive effcts between time and grouping (P<0.05). The Barthel Index of the intervention group was significantly higher than that of the control group when patients were discharged( P<0.05 ). Conclusion Early mobilization intervention can effectively slow down the decrease of muscle strength of mechanically ventilated patients 48 hafter entering ICU and reduce the incidence of ICU acquired weakness when leaving ICU.
