The Effects of Two Different Burn Dressings on Serum Oxidative Stress Indicators in Children with Partial Burn

Area of Science:

• Biomedical Engineering
• Pediatric Surgery
• Wound Healing Research

Background:

• Systemic inflammatory response and oxidative stress are critical complications in pediatric thermal burn injuries.
• Current burn dressings vary in their impact on systemic physiological markers.
• Understanding the systemic effects of wound management is crucial for optimizing patient outcomes.

Purpose of the Study:

• To compare the efficacy of polylactic membrane (PLM) versus hydrofiber dressing with silver (HFAg) in modulating systemic oxidative stress in children with thermal burns.
• To evaluate the impact of these dressings on serum markers of oxidative stress, including malondialdehyde (MDA), total antioxidant capacity (TAC), total oxidant capacity (TOC), and glutathione (GSH).

Main Methods:

• A prospective, randomized, and matched-pair study involving pediatric patients with 20-50% TBSA thermal burns.
• Serum levels of MDA, TAC, TOC, and GSH were measured at multiple time points post-injury.
• Statistical analysis was performed to compare treatment groups and a control group of healthy children.

Main Results:

• PLM treatment led to a significantly greater increase in TAC and GSH levels compared to HFAg.
• Serum TOC levels decreased to normal ranges by day 3 in the PLM group, whereas HFAg showed a slower response.
• TAC levels increased more substantially, and TOC decreased more rapidly in the PLM group, suggesting a more potent antioxidant effect.

Conclusions:

• Different burn dressings exert distinct systemic effects on oxidative stress markers in pediatric burn patients.
• PLM dressings appear to possess antioxidant properties, potentially due to their lactate content, leading to more effective reduction of systemic oxidative stress compared to HFAg.
• The findings suggest that PLM may be a superior option for managing systemic oxidative stress in pediatric thermal burn injuries.
