title: [Clinical review of enteral feeding of extremely low birth weight infants].
abstract: OBJECTIVE
  To review the clinical data of enteral feeding of extremely low birth weight infants (ELBWI), and analyze the influencing factors.
  
  
  METHODS
  From Jan. 2000 to Jan. 2010, data of 31 ELBWI from Peking Union Medical College Hospital were retrospectively collected. ELBWI were assigned to different groups according to the time achieving full enteral feeding, comparison was done between two groups for enteral feeding.
  
  
  RESULTS
  Twenty-four infants were analyzed, their mean gestational age was (29.0 ± 1.8) weeks (26.14 - 34.43 weeks), birth weight (882 ± 67) g (730 - 970 g), there were 11 infants in group A, whose time for achieving full enteral feeding was (27 ± 6)days, there were 13 infants in group B, whose time achieving full enteral feeding was (46 ± 10)days. The ratio of asphyxia (18.2% vs. 61.5%, P = 0.047), duration of umbilical vein catheterization longer than 10 days (18.2% vs. 61.5%, P = 0.047), and duration of mechanical ventilation longer than 14 days (27.3% vs. 76.9%, P = 0.038) in group A was higher than in group B. The milk volume on the 21st and 28th day in group A was much more than that in group B [(88.9 ± 35.4) ml vs. (37.4 ± 34.9) ml, P = 0.002; (121.1 ± 37.4) ml vs. (53.2 ± 33.1) ml, P = 0.000]. There were no significant differences between the two groups in gestational age, birth weight, patent ductus arterious, erythrocytosis, dysglycemia, sepsis, the time to begin enteral feeding, the beginning milk volume, the adding milk volume in the 1st, 2nd week, and the milk volume on the 3rd, 7th, 14th day.
  
  
  CONCLUSIONS
  Asphyxia, duration of umbilical vein catheterization, and duration of mechanical ventilation are likely to influence the enteral feeding of ELBWI, ELBWI with successful enteral feeding could show good tolerance in the 3rd week. But individual program should be made for enteral feeding of ELBWI, because enteral feeding could be influenced by multiple factors.
