So this study compared indicators of oxidative stress in pregnancy with labor and correlation labor indices with newborn. Methods: In this cross – sectional study in 1386, 60 pregnant women at 38-40 weeks gestation were sampled and drowned 5 cc blood. All of the mothers for blood sample was taken written consent form. After interring pain less labor through of Entonox method 5 cc of venous blood taken at the second stage of labor and newborn cord. Then lipid peroxidation, thiols groups and total antioxidant capacity was assessed. Result: findings showed that the mean age was 24.0862 ± 4.08. Lipid peroxidation in pregnancy was 4.61 ± 2.712 and during labour was 4.606 ± 3.32, that the difference was not significant (p=0.994). Thiol index in pregnancy was 0.284 ± .3889 and during lbour 0.2656 ± .24371 that difference was not significant (p= 0.694). There wasn’t any significant difference in FRAP levels in pregnancy 1.26 ± 1.015 and labour 1.370 ± 1.1126 too (p=0.56). Significant positive correlation between maternal and fetal index thiols (p=0.002) and lipid peroxidation was observed (p=0.001). Conclusion: The results showed that oxidative stress indicators in the labor does not differ with respect to pregnancy and can be used for this method of analgesia M3 ER -
