Abstract
Objective. To compare the indicators of acid-base balance in the neonatal umbilical cord artery and vein in health and fetal hypoxia. Material and methods. A prospective observational study was performed using 98 umbilical cord blood samples. Results. The pH value was lower in the umbilical artery (7.252 ± 0.100 than that in the umbilical vein (7.297 ± 0.097) (p < 0.0001). The lactate level did not differ and was 5.929±2.807 mmol/l in the umbilical artery and 5.661 ± 2.898 mmol/l in the umbilical vein (p = 0.1074). The partial pressure of carbon dioxide was predictably higher in the umbilical artery (47.56 ± 12.68 mm Hg) than that in the umbilical vein (39.69 ± 9.70 mm Hg) (p < 0.0001); the partial pressure of oxygen was higher in the umbilical vein (17.56 ± 6.134 mm Hg) than that in the umbilical artery (23.36 ± 10. 09 mm Hg) (p < 0.0001). Conclusion. When pH values are determined, the source of umbilical cord blood sampling is critically important, whereas when lactate levels are measured, any umbilical vessel may be used. It is important to take into account the found patterns in clinical practice.
