An overview of current research on nutritional support for burn patients: A bibliometric analysis from 1983 to 2022

Burn patients are reportedly prone to complications, such as skeletal muscle wasting, anemia, and slow wound healing, during treatment, due to disease and metabolic depletion, which affect prognosis. Nutritional support is essential in treating burns and can significantly improve patient survival and reduce complications such as infection. This study aimed to perform a bibliometric analysis of the existing literature on nutritional support for burns and to explore possible future research trends.

The literature related to nutritional support for burns from 1983 to 2022 was searched on Web of Science. The included literature was used for bibliometric analysis using VOSviewer and CiteSpace software.

There were 260 publications on nutritional support for burns. The United States contributes significantly to research in this area. The United States has the highest number of publications (n = 119) and citations (n = 4424). Nutrition support was the keyword with strongest burst intensity. A diet of ≥ 60% carbohydrates and 12% to 15% fat is suitable for burn patients, but the optimal ratios have not been fully determined.

An optimal nutritional support program is essential for treating burn patients. Individualized nutritional support programs are the trend in this field. At present, more rigorous multicenter prospective studies with large samples are needed to explore the optimal ratios for specific dietary programs, especially macronutrients, to achieve satisfactory nutritional support and improve patient prognosis.
