To compare oxidative stress due to conventional and LED phototherapy among jaundiced preterm neonates.
Cross-sectional study conducted in NICU on 82 neonates (equal numbers received conventional and LED phototherapy). Total antioxidant capacity (TAC), total oxidant status (TOS) and Oxidative stress index (OSI) were assessed.
Post-phototherapy, mean (SD) OSI increased significantly compared to baseline in both conventional [0.26 (0.24) vs. 0.61 (0.41); P<0.001] and LED groups [0.24 (0.20) vs. 0.32 (0.23); P<0.001]. Across groups, mean (SD) TAC was lower [0.28 (0.16) vs. 0.53 (0.27); P<0.001] mmol Trolox equiv/L; mean (SD) TOS higher [15.6 (10.9) vs. 14.6 (10.2); P=0.711] µmol H2O2/L and mean (SD) OSI higher [0.61 (0.42) vs. 0.33 (0.23); P<0.001] in conventional as compared to LED phototherapy.
Both modes increased oxidative stress index; however, conventional phototherapy resulted in higher oxidative stress.
比较接受传统光疗和LED光疗的黄疸早产儿的氧化应激情况。
在新生儿重症监护病房对82例新生儿进行横断面研究（接受传统光疗和LED光疗的人数相等）。评估总抗氧化能力（TAC）、总氧化状态（TOS）和氧化应激指数（OSI）。
光疗后，传统光疗组[0.26（0.24）对0.61（0.41）；P<0.001]和LED光疗组[0.24（0.20）对0.32（0.23）；P<0.001]的平均（标准差）OSI较基线均显著升高。两组间，传统光疗组的平均（标准差）TAC较低[0.28（0.16）对0.53（0.27）；P<0.001]mmol Trolox当量/L；平均（标准差）TOS较高[15.6（10.9）对14.6（10.2）；P=0.711]μmol H2O2/L，平均（标准差）OSI较高[0.61（0.42）对0.33（0.23）；P<0.001]。
两种光疗模式均增加了氧化应激指数；然而，传统光疗导致更高的氧化应激。
