Purified hemoglobin spray had emerged as a potential adjunctive therapy to accelerate wound healing in pediatric patients with burns. This retrospective study aimed to compare the healing process and post-treatment outcomes of children with second-degree burns treated with or without purified hemoglobin spray in a tertiary burn unit between December 1, 2023, and December 1, 2024. Data including demographics, burn characteristics (source, percentage, depth), number of dressings, length of hospital stay, and the day of complete epithelialization were recorded. Follow-up assessments at 3 and 6 months post-discharge evaluated the presence of pruritus and epithelialization defects, including hypertrophic scarring, pigmentation changes, or contractures. Patients treated with 99.9% purified hemoglobin spray had significantly shorter hospital stays and epithelialization times (p < 0.001). Post-discharge pruritus was also significantly less common in this group (p < 0.001). The risk of developing pigmentation defects and epithelialization defects at the third month after discharge was reduced by 94.0% and 90.9%, respectively, while at the sixth month the risk of pigmentation defects was reduced by 90.9% and the risk of hypertrophic scar development during the 6-month follow-up period was reduced by 93.3%. These findings suggested that purified hemoglobin spray might enhance wound healing, reduce the need for frequent dressing changes, and minimize long-term complications in pediatric burn care.
