Effect of early enteral nutrition on prognosis of patients during veno-arterial extracorporeal membrane oxygenation / 中国中西医结合急救杂志

ABSTRACT

Objective To observe the feasibility of early enteral nutrition (EEN) in adult patients during veno-arterial extracorporeal membrane oxygenation (VA-ECMO) and its related clinical results. Methods Thirty-four patients admitted to the Intensive Care Unit (ICU) of Ningbo Medical Center Li Huili Hospital from January 2012 to December 2017 to receive VA-ECMO treatment were selected as the study objects. All patients received EEN after exclusion of contraindications; the target calories were calculated by using 104.65 kJ·kg-1·d-1(25 kcal·kg-1·d-1) and according to 1.2 g·kg-1·d-1, the target protein requirements were calculated. Within one week of EN energetic treatment, if the feeding amount reached 80% or over of the above calculated targets, the EN administration was fulfilling the standard, thus the patients were divided into a standard group and a non-standard group, After ICU admission, the acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) score, multiple organ dysfunction syndrome (MODS) score, the time from the beginning of ECMO to the start of EN, time reaching feeding standard, VA-ECMO persistent days, ICU days of stay, total hospitalization days, hospital mortality, and reasons for feeding interruptions were recorded, and the effects of EEN on prognosis of patients during VA-ECMO were analyzed in the two groups. Results The APACHE Ⅱ score and MODS score of the non-standard group were higher than those of the standard group on admission of ICU (APACHE Ⅱscore 25.50±5.62 vs. 19.91±8.53, MODS score 11.08±3.26 vs. 6.73±2.05, both P < 0.05), and the hospital mortality was lower in the standard group than that in non-standard group [40.9% (9/22) vs. 83.3% (10/12), P < 0.05]. The comparisons of differences in time from the beginning of ECMO to the start of EN, time of reaching feeding standard, VA-ECMO treatment days, ICU days of stay, hospitalization days between the two groups were of no statistical significance (all P > 0.05). The most common reason for interruption of feeding was high gastric residual volume (GRV). Conclusion Whether a critically ill patient receiving VA-ECMO can reach the target feeding amount in a week or not is related to the degree of disease severity; it is difficult for a seriously ill patient to reach the target amount of feeding, that may affect their prognosis.
