To explore the therapeutic effects of early enteral nutrition (EEN) on patients with sepsis on mechanical ventilation.
Methods:
Patients with sepsis on mechanical ventilation in the medical intensive care unit (ICU) from January 2013 to March 2016 were treated with enteral nutrition. Patients treated within 48 hours of initiation of mechanical ventilation were assigned to the EEN group, and the rest were assigned to the delayed enteral nutrition (DEN) group. Peripheral blood Th17 cells and Treg cells, endotoxin (ET) level, 28-day mortality, duration of mechanical ventilation, lengths of ICU stay and hospital stay, and incidence of ICU-acquired weakness (ICU-AW) were analyzed between the 2 groups.
Results:
The proportion of Th17 cells and ET levels in the EEN group were significantly lower than those in the DEN group, whereas the proportion of Treg cells in the EEN group was remarkably higher than that in the DEN group (P < .05). The duration of mechanical ventilation, lengths of ICU stay and hospital stay, and incidence of ICU-AW were higher in the DEN group than in the EEN group (P < .05), but there was no significant difference in the 28-day mortality between the 2 groups.
Conclusion:
Patients with sepsis mainly present with an increased proportion of Th17 cells in the early stage, manifesting as enhanced immune response. Early enteral nutrition can inhibit the excessive immune response, shorten the duration of mechanical ventilation, lengths of ICU stay and hospital stay, and reduce the incidence of ICU-AW, but it has no obvious effect on 28-day mortality.
