Maternal and newborn levels of glucose, sodium and osmolality after preloading with three intravenous solutions during elective cesarean sections

The influence of maternal i.v. loading with 1500 ml fluid prior to epidural anesthesia and elective cesarean section was studied in 60 healthy parturients near term. Three different solutions were used. Normal saline 0.9%, Hartmann's solution and dextrose 5%. A significant rise in glucose level accompanied by a significant decrease in sodium level was found in mothers and newborns of the group hydrated with the dextrose solution.
