Abstract
Objective. To evaluate the impact of a forced feeding procedure on the rate and degree of hyperglycemia in extremely low and very low birth weight (ELBW and VIBW) infants. Subjects and methods. A total of 120 neonates, including 47EIBWinfants and 73 VLBWinfants, who had been treated in an intensive care unit in January 2012 to January 2014, were examined. Blood glucose levels were determined in all the babies. The two-fold increased blood glucose level (>8.0 mmol/l) at a 4-hour interval was considered to be hyperglycemia. The infants were divided into the following groups according to gestational age: 1) 25-27weeks (n=22); 2) 28-29 weeks (n=43), 3) 30-31 weeks (n=40), and 4) 32-33 weeks (n=15). Each group was divided into subgroups in relation to a parenteral feeding procedure: A) forcedfeeding; B) traditional feeding. Results. The investigation established that the difference in the rate of hyperglycemia was statistically insignificant in relation to the feeding procedure. This trend was noted in all the groups. Comparative analysis of the two parenteral feeding procedures also re vealed no increase in the mean blood glucose levels in the forced feeding subgroups in the first week of life. Comparison of the rate of intragastric bleeding (IGB) in the examined groups showed a statistically significant increase in the rate of grade 1-2 IGB in Subgroup В of Group 1 versus Subgroup A. Examination of the two parenteral feeding procedures revealed no statistical difference in the incidence of retinopathy of prematurity. Analysis of the possible complications of parenteral nutrition in Group 1 patients demonstrated a rise in the incidence of neonatal cholestasis in Subgroup В versus Subgroup A. There was no significant difference in the incidence of neonatal cholestasis or IGB in the groups of infants at more than 27 weeks’ gestation (p > 0.05). Conclusion. The forcedfeeding procedure in ELBW and VLBW infants does not result in a significant increase in the rate and degree of hyperglycemia. The lack of an increase in the frequency of complications of hyperglycemia, such as IGB, retinopathy, neonatal cholestasis, additionally suggests that the forced feeding procedure is safe.
