Effect of enteral nutrition via nasal jejunal tube on liver function / 中华临床营养杂志

ABSTRACT

Objective To observe the liver function changes in patients after enteral nutrition through nasal jejunal tube.Methods Altogether 74 inpatients requiring enteral nutrition were collected for this study from September 2011 to August 2014 in the Intensive Care Unit of Zhengzhou People's Hospital and divided into 2 groups with random number tablethe nasal jejunal tube group (n =36) and the nasogastric tube group (n ＝38),with nasal jejunal tube and nasogastric tube inserted,respectively,for early enteral nutrition.We observed the two groups of patients in terms of liver function indexes on day 7 and day 14 after starting enteral nutrition.Results In the nasal jejunal tube group,31 patients (86.11％) showed abnormality in at least 1 liver function index,while that number was 23 in the nasogastric tube group (60.53％),with significant inter-group difference (x2 =6.136,P =0.013).On day 7 after enteral nutrition,there were no significant differences in alanine transaminase (ALT),aspartate transaminase (AST),alkaline phosphatase (ALP),γ-glutamyl transpeptidase (γ-GGT) and albumin (ALB) between the two groups [(39.1 ± 8.6) U/L vs.(42.3 ±8.9) U/L,t=-1.475,P=0.145;(36.2±6.8) U/Lvs.(38.0±7.1) U/L,t=-1.237,P=0.220;(61.8±11.5) U/Lvs.(63.1 ±13.2) U/L,t=-0.696,P=0.489;(47.3±8.2) U/Lvs.(50.5±7.5) U/L,t=-1.640,P=0.106;(35.2±6.7) g/Lvs.(36.2±7.4) g/L,t=-0.610,P=0.543];but on day 14,the nasal jejunal tube group had significantly higher levels of ALP,γ-GGT,and ALB compared with the nasogastric tube group [(201.2 ± 15.2) U/L vs.(116.5 ± 13.6) U/L,t =-25.380,P =0.000;(109.4±7.2) U/Lvs.(49.2±6.5) U/L,t=-37.665,P=0.000;(37.2±7.1) g/Lvs.(30.1±6.5) g/L,t =-4.490,P =0.000].On day 7 and day 14,there were no statistically significant differences in totalbilirubin [(4.6±0.9) μmol/L vs.(4.8 ± 1.0) μmol/L,t =-0.905,P=0.368;(4.8±12) μmol/Lvs.(5.2±1.1) μmol/L,t=-1.492,P=0.140],indirect bilirubin [(6.1 ±0.8) μmol/Lvs.(6.3±0.9) μmol/L,t=-1.012,P=0.315;(6.9±0.9) μmol/L vs.(7.3±1.0) μmol/L,t=-1.811,P =0.074],and direct bilirubin [(4.0 ± 0.6) μmol/L vs.(3.9 ± 0.5) μmol/L,t =0.777,P =0.440;(5.1 ±0.8) μmol/L vs.(5.4±0.9) μmol/L,t=-1.517,P=0.134] between the nasogastric tube and the nasal jejunal tube groups.The incidence of pulmonary infection in the nasal jejunal tube group was significantly lower than that in the nasogastric tube group (30.56％ vs.55.26％,x2 =4.598,P =0.032).Conclusion Compared with enteral nutrition through nasogastric tube,enteral nutrition through nasal jejunal tube may be more likely to lead to abnormal liver function.
