입원환자의 조기 경장영양의 효과와 영양집중지원팀의 역할

Purpose: The study examined the effects of early enteral nutrition on the patients’ length of stay in an intensive care unit (ICU), length of stay and mortality rate. Methods: A retrospective design was employed with a total of 461 patients (mean age=69.9±15.6 years; 253 males; 208 females). They were divided into two groups according to when they received enteral feeding: an “early enteral nutrition” (EEN) group of 148 patients (32.1%) who received enteral feeding within 48 hours of their arrival at the hospital and a “delayed enteral nutrition” (DEN) group of 313 patients (67.9%) who received enteral feeding at some point after 48 hours of their arrival at the hospital. The EEN group and control group were similar in terms of age, sex, body mass index, and underlying diseases. Results: The EEN group’s total length of stay in hospital was shorter (23.29±27.19 days) than that of the control group (36.74±32.24 days); the difference was significant (P＜0.001). The EEN group also showed a shorter length of stay in the ICU (13.67±22.77 days) than the DEN group (17.46±21.02 days) and a lower mortality rate (17.6%) than the control group (18.8%), but these differences were not significant. Conclusion: The study found that early enteral nutrition treatment reduced total length of stay in hospital significantly. The findings suggest that early enteral nutrition treatment plays an important role in the patients’ recovery and prognosis.
