Introduction: Electrical burns cause significant morbidity and mortality worldwide. Here we measured changes in levels of serum oxidative stress and telomerase in children suffering from high-voltage electrical burn (HVEB) injuries and other burns and the significance of these parameters in terms of amputation.
Materials and methods: After obtaining approval from our ethics committee for this prospective study, we formed three groups: a group of 18 children with HVEBs, a group of 18 children with thermal burns, and a control group. All children were 1-16 years of age. The HVEB group was divided into HVEB-WA (without amputation) and HVEB-A (with amputation) subgroups. Serum malondialdehyde (MDA) level, total antioxidant capacity (TAC), total oxidant capacity (TOC), glutathione (GSH) level, and telomerase level were measured and compared among the groups.
Results: The patients differed in terms of demographics. The healing time of the HVEB group was longer than that of the thermal burn group, and the oxidative stress indicators of the HVEB group remained higher for longer. The mean oxidative stress indices in the HVEB-A group were higher than those in the HVEB-WA group and remained elevated for longer.
Conclusion: HVEBs are more destructive than thermal burns; damage may progress over time, and healing takes longer. Healing can be followed biochemically by measuring levels of oxidative stress indicators. Indications for amputation, if not initially obvious, can be predicted by evaluating these indicators, affording therapeutic advantages. (C) 2018 Elsevier Ltd and ISBI. All rights reserved.
