Abstract

Background

Supraglottic Airway Devices (SADs) are essential in airway management. However, little is known about their use, perceptions, and barriers in large, resource-variable healthcare systems such as Brazil. We aimed to assess current practice patterns, training exposure, and barriers to SADs use among Brazilian anesthesiologists and trainees.

Methods

A nationwide, web-based survey that addressed demographics, training exposure, device availability, frequency of use, perceived safety and efficacy, barriers to use, and knowledge of SADs generations. Descriptive and inferential statistics were used to analyze regional and experiential patterns.

Results

A total of 432 completed responses were analyzed. Most respondents were fully trained anesthesiologists (75.5%) from all five Brazilian regions. Although SADs were widely perceived as safe (76.9%) and capable of providing adequate ventilation (74.3%), only 35% reported using them at least once per week, and fewer than 20% felt confident distinguishing between first and second-generation devices. Binomial logistic regression revealed that greater training exposure during residency was strongly associated with more frequent current use (OR = 7.3; 95% CI 3.8‒14.3, p < 0.001). The most common barrier was lack of operator experience (81.5%), followed by limited availability of devices (28.9%). Use varied across regions (p  < 0.001), with 82% of anesthesiologists in the South reporting weekly use compared to only 15.4% in the North. Respondents were more likely to use SADs in limb surgeries, while use is limited in gastrointestinal and thoracic procedures.

Conclusions

Despite favorable perceptions of safety and efficacy, SADs remain underused in Brazil, with marked regional variation and limited familiarity with device generations. Training exposure emerged as a strong predictor of current use, underscoring the importance of structured education and hands-on experience. Addressing gaps in training and improving device availability may help standardize practice and enhance the use of SADs across the country.

Resumo

Introdução

Os dispositivos supraglóticos de vias aéreas (DSAs) são essenciais no manejo das vias aéreas. No entanto, pouco se sabe sobre seu uso, percepções e barreiras em sistemas de saúde grandes e com recursos variáveis, como o Brasil. Nosso objetivo foi avaliar os padrões de prática atuais, a exposição ao treinamento e as barreiras ao uso de DSAs entre anestesiologistas e formandos brasileiros.

Métodos

Um inquérito nacional baseado na web que abordou dados demográficos, exposição ao treinamento, disponibilidade de dispositivos, frequência de uso, percepção de segurança e eficácia, barreiras ao uso e conhecimento das gerações de DSAs. Estatísticas descritivas e inferenciais foram usadas para analisar padrões regionais e de experiência.

Resultados

Foram analisadas 432 respostas completas. A maioria dos respondentes era composta por anestesiologistas com formação completa (75,5%) de todas as cinco regiões brasileiras. Embora os DSAs tenham sido amplamente percebidos como seguros (76,9%) e capazes de fornecer ventilação adequada (74,3%), apenas 35% relataram usá-los pelo menos uma vez por semana, e menos de 20% sentiram-se confiantes em distinguir entre dispositivos de primeira e segunda geração. A regressão logística binomial revelou que uma maior exposição ao treinamento durante a residência estava fortemente associada a um uso atual mais frequente (OR = 7,3; IC 95% 3,8–14,3, p < 0,001). A barreira mais comum foi a falta de experiência do operador (81,5%), seguida pela disponibilidade limitada de dispositivos (28,9%). O uso variou entre as regiões (p < 0,001), com 82% dos anestesiologistas no Sul relatando uso semanal em comparação com apenas 15,4% no Norte. Os respondentes foram mais propensos a usar DSAs em cirurgias de extremidades, enquanto o uso é limitado em procedimentos gastrointestinais e torácicos.

Conclusões

Apesar das percepções favoráveis de segurança e eficácia, os DSAs continuam sendo subutilizados no Brasil, com marcante variação regional e familiaridade limitada com as gerações dos dispositivos. A exposição ao treinamento surgiu como um forte preditor do uso atual, ressaltando a importância da educação estruturada e da experiência prática. Abordar as lacunas no treinamento e melhorar a disponibilidade de dispositivos pode ajudar a padronizar a prática e aumentar o uso de DSAs em todo o país.
