Introduction: Chronic wounds impose a sustained clinical burden, and local management requires alternatives supported by evidence of effectiveness and safety. Objective: To compare the evolution of linear dimensions of chronic extremity wounds treated with 10% spruce resin ointment or conventional silver sulfadiazine care. Methods: This retrospective, analytical, longitudinal cohort included 82 patients treated from August 2024 to February 2025 at a specialised clinic in Lima. Forty records documented silver sulfadiazine and 42 documented spruce resin. Maximum and minimum wound lengths were recorded at baseline and at weeks 2, 4, and 6. Results: Baseline dimensions were comparable according to the recorded analysis (p > 0.05). At week 6, mean maximum and minimum lengths were 3.43 and 2.29 mm in the resin group, compared with 30.75 and 24.75 mm in the conventional group; reported between-group comparisons were p < 0.001. No superinfection was documented in the resin group. Conclusions: Documented use of 10% spruce resin was associated with greater reduction in linear wound dimensions over six weeks. The retrospective, non-randomised design requires confirmation in controlled trials that include aetiology, wound area, complete closure, and safety outcomes.

Introducción: Las heridas crónicas imponen una carga clínica sostenida y su abordaje local requiere alternativas con evidencia de efectividad y seguridad. Objetivo: Comparar la evolución de las dimensiones lineales de heridas crónicas de extremidades tratadas con ungüento de resina de abeto al 10 % o cura convencional con sulfadiazina de plata. Métodos: Cohorte retrospectiva, analítica y longitudinal de 82 pacientes atendidos entre agosto de 2024 y febrero de 2025 en una clínica especializada de Lima. Se analizaron 40 registros con sulfadiazina de plata y 42 con resina de abeto. La longitud mayor y menor se registraron al inicio y en las semanas 2, 4 y 6. Resultados: Las dimensiones basales fueron comparables según el análisis consignado (p > 0,05). En la semana 6, las medias de longitud mayor y menor fueron 3,43 y 2,29 mm en el grupo resina, frente a 30,75 y 24,75 mm en el convencional; las comparaciones reportadas fueron p < 0,001. El registro clínico no documentó sobreinfección en el grupo resina. Conclusiones: El uso documentado de resina de abeto al 10 % se asoció con mayor reducción de las dimensiones lineales durante seis semanas. Por el diseño retrospectivo y no aleatorizado, el hallazgo requiere confirmación mediante ensayos controlados que incluyan etiología, área, cierre completo y seguridad.
