J Pediatr Surg. 2022 Dec 22:S0022-3468(22)00781-3. doi: 10.1016/j.jpedsurg.2022.12.008. Online ahead of print.


BACKGROUND: Carboxytherapy involves injecting carbon dioxide in the dermal and subcutaneous layers to achieve an increase in the local microvascularization of the tissue where it is applied. Our aim is to analyze its effectiveness in the treatment of pathological scars, as well as its adverse effects.

METHODS: We conducted a prospective single-center study in patients under 18 years of age with atrophic and hypertrophic scars caused by surgical interventions or trauma, mainly burns. Each patient underwent two sessions, 6 weeks apart in time. Scar quality was evaluated using the Vancouver Scar Scale before the first session and 6 weeks after the second session. Adverse effects observed during the procedure and at follow-up in outpatient clinic were collected.

RESULTS: A total of 16 patients were included (5 males; 11 females), with a median age of 12.7 years (interquartile range 8.5-15.2), in whom 25 pathologic scars were treated (14 atrophic and 11 hypertrophic). All sessions were performed under sedation, and patients were discharged the same day, without the need for hospitalization. Regarding scar quality, an improvement was observed in the median Vancouver scale score at 6 weeks after the second session (7 points) compared to the initial median score (12 points), this difference being statistically significant (p = 0.031). No serious adverse effects were observed during the procedure or during subsequent follow-up, with a median follow-up of 14 weeks.

CONCLUSIONS: Carboxytherapy is an effective and safe minimally invasive therapy for pathologic scars, achieving a significant improvement in scar quality, with almost no contraindications.
