Abstract: Objective: To explore whether there are differences in the levels of protein, glucose and blood lipids in umbilical vein and umbilical artery blood of newborns with different delivery modes, and to evaluate their value as indicators of fetal intrauterine nutrition and nutritional support.
Methods: A total of 89 pairs of mothers and infants who were delivered in Danyang People's Hospital of Jiangsu Province from June to September 2021 were selected as the study subjects, including 38 cases of spontaneous delivery and 51 cases of cesarean section. The basic information of pregnant women, pregnancy information, newborn delivery and physical examination information were extracted from the medical record information system of the hospital. According to the mode of delivery, HITACHI 7600 automatic biochemical analyzer was used to measure the levels of protein, glucose and blood lipids in umbilical vein and umbilical artery blood, including total protein(TP), albumin(ALB), glucose(GLU), total cholesterol(TC), triglyceride(TG), high density lipoprotein cholesterol(HDL-C), low density lipoprotein cholesterol(LDL-C). The data were statistically analyzed using IBM SPSS Statistics 26.0 statistical software.
Results: The levels of TP, ALB, GLU, TC, TG, HDL-C and LDL-C in the umbilical vein blood of the spontaneous delivery group were(56.40±5.83)g/L, (38.41±3.43)g/L, (4.55±1.53)mmol/L, (1.68±0.42)mmol/L, (0.25±0.11)mmol/L, (0.84±0.17)mmol/L and(0.69±0.23)mmol/L, respectively. The levels of TP, ALB, GLU, TC, TG, HDL-C and LDL-C in umbilical artery blood were(56.49±9.91)g/L, (37.72±4.77)g/L, (4.07±1.52)mmol/L, (1.60±0.42)mmol/L, (0.24±0.10)mmol/L, (0.80±0.18)mmol/L and(0.68±0.24)mmol/L, respectively. The levels of TP, ALB, GLU, TC, TG, HDL-C and LDL-C in umbilical vein blood of cesarean section group were(52.08±4.12)g/L, (36.12±2.13)g/L, (3.45±1.16)mmol/L, (1.61±0.39)mmol/L, (0.19±0.08)mmol/L, (0.82±0.18)mmol/L and(0.61±0.20)mmol/L, respectively. The levels of TP, ALB, GLU, TC, TG, HDL-C and LDL-C in umbilical artery blood were(51.49±7.59)g/L, (35.40±3.60)g/L, (3.09±1.15)mmol/L, (1.48±0.40)mmol/L, (0.19±0.08)mmol/L, (0.78±0.18)mmol/L and(0.60±0.20)mmol/L, respectively. The levels of TP, ALB, Glu and TG in cord vein blood and cord artery blood in spontaneous labor group were significantly higher than those in cesarean section group(P<0.05); The levels of Glu, TC, TG and HDL-C in cord vein blood were significantly higher in spontaneous labor group and cesarean section group than those in cord artery blood(P<0.05).
Conclusion: The levels of protein, glucose and blood lipids in umbilical vein and umbilical artery blood were different among different delivery modes.
