Abstract: Objective To observe the levels about vitamin A and mineral with neonatal respiratory distress syndrome (NRDS). Methods A total of 40 neonates with NRDS were chosen as research group in the neonatal department of Dezhou People's Hospital,and 30 healthy neonates were enrolled into the study as control group.The levels of vitamin A,calcium,magnesium,copper,iron and zinc were detected from venous blood at 24 h after being admitted to hospital. Result The level of vitamin A in the research group were lower than that in the control group (P<0.01),The levels of iron and zinc in the research groups were lower than those in the control group (P<0.05),and there were no significant differences on the levels of calcium,magnesium and copper between two groups (P>0.05). Conclusions Vitamin A,iron and zinc could promote the development of the lung tissue,enhance the content and activity of the pulmonary surfactant and reduce the occurrence rate and the severity of NRDS.
