title: [Cord blood insulin and erythropoietin levels in relation to the mode of delivery].
abstract: The aim of the study was evaluation, whether cord blood insulin (Ic) and erythropoietin (EPO) levels differ in accordance with mode of delivery: cesarean section (CS) or vaginal delivery (VD).
  
  
  METHODS
  The study was performed in the diabetic group consisted of 148 newborns of diabetic mothers (NDM)--90 of them with GDM and 58 with IDDM as well as in the control group consisted of 100 newborns born to healthy mothers. 52.0% of NDM and 38.0% control subjects were delivered by cesarean section. The most frequent reason for performing CS in the diabetic group was fetal distress before labor and in the control group--fetal distress during labor. Cord blood Ic and EPO levels were compared in accordance with type of delivery: CS or VD. Into statistical analysis Mann-Whitney test was used.
  
  
  RESULTS
  There were found that cord blood Ic and EPO levels in NDM born by CS are significantly higher than in those born by VD (Ic--38.2 +/- 41.5 versus 26.6 +/- 38.6 mIU/ml adequately and EPO--51.8 +/- 76.0 versus 26.8 +/- 29.9 mU/ml adequately). There were no such differences in the control group.
  
  
  CONCLUSIONS
  1. Fetal hyperinsulinemia in perinatal period is often connected with occurrence of indications for performing cesarean section in pregnant women with diabetes mellitus. 2. Cesarean section in diabetic pregnant women is often connected with previous fetal hypoxia.
