The limited number of bibliometric studies in the literature have generally focused on the top-cited studies in the field of anesthesia, however, there is a lack of studies that made a holistic bibliometric evaluation of these works. The purpose of this study is to make a contemporary summary of the articles published in the field of anesthesia within the last 10 years through detailed bibliometric methods.

The articles published between the years 2009 and 2018 were downloaded from the Web of Science (WoS) database and analyzed using bibliometric methods. The literature review was conducted using the keyword “Anesthesiology” in the “Research Area” category via the advanced search option available in WoS. The relation between the number of publications of the countries and the Gross Domestic Products and Human Development Index values were analyzed using Spearman's correlation coefficient. The number of articles between the years 2019 and 2021 was estimated through linear regression analysis.

A review of the literature indicated 41,003 articles in the Web of Science database. Estimations included 4,910 (3,971–5,849) articles for the year 2019. There was a high-level, positive significant correlation between the number of publications and Gross Domestic Product (r = 0.776, p < 0.001).

The findings show that countries with high income are effective in the field of anesthesia, which indicates a strong association between research productivity and economic development. Undeveloped and developing countries should be encouraged to conduct research in the field of anesthesia.

Existe um número limitado de estudos bibliométricos na literatura, que no campo da anestesiologia, concentram-se de forma geral nos estudos mais citados. Entretanto, existem poucos estudos de avaliação bibliométrica holística dessas publicações. O objetivo do presente estudo foi fazer um resumo contemporâneo dos artigos publicados no campo da anestesiologia nos últimos 10 anos usando métodos bibliométricos detalhados.

Os artigos publicados entre 2009 e 2018 foram extraídos do banco de dados Web of Science (WoS) e analisados usando métodos bibliométricos. A revisão da literatura foi conduzida usando o unitermo “Anesthesiology” (Anestesiologia) na categoria “Research Area” (Área de Pesquisa) via a opção de busca avançada disponível no WoS. A relação entre o número de publicações de cada país e os valores do Produto Interno Bruto e Índice de Desenvolvimento Humano foi analisada usando o coeficiente de correlação de Spearman. O número de artigos para os anos de 2019 a 2021 foi estimado através de análise de regressão linear.

A revisão da literatura encontrou 41.003 artigos no banco de dados Web of Science. As estimativas incluíram 4.910 (3.971–5.849) artigos para o ano de 2019. Houve correlação de alto grau, positiva, significante entre o número de publicações e Produto Interno Bruto (r = 0,776; p < 0,001).

Os achados mostram que países de alta renda são efetivos no campo da anestesiologia, indicando uma forte associação entre a produtividade em pesquisa e desenvolvimento econômico. Países não desenvolvidos ou em desenvolvimento devem ser estimulados a conduzir pesquisa no campo da anestesiologia.
