Application effect of nutritional support combined with early motion based on protection motivation theory in ICU-acquired weakness

Abstract

To explore the effect of nutritional support combined with early motion based on protection motivation theory in acquired weakness in critically ill patients. Patients treated in Intensive care unit (ICU) after operation from January to December in 2021 were selected as the study subjects. Historial control trial (HCT) was used. Patients admitted from January to June were the control group, and those admitted from July to December were the intervention group. Routine ICU management was used in the control group, and early motion combined with nutritional support was used in the intervention group. The incidence of ICU-acquired weakness (ICU-AW), activities of daily living (ADL), nutritional status, ICU stay, total hospital stay along with mechanical ventilation time were compared between the control and intervention groups. Before intervention, there was no significant difference among PatientGenerated Subjective Global Assessment (PG-SGA) score, serum total protein (TP) and albumin (ALB) between the control and intervention groups. After intervention, the incidence of ICU-AW, Barthel (BI) score, PG-SGA score, serum TP and ALB in the intervention group were conspicuously better in comparison with control group. The ICU stay, mechanical ventilation time and total hospital stay were significantly shorter than that in the control group. Nutritional support combined with early motion based on protection motivation theory can abate the incidence of ICU-AW, improve the activities of daily living and the nutritional status of patients, and shorten the hospital stay and mechanical ventilation.
