Resumo

Introdução: Os doentes submetidos a cirurgia sob anestesia geral devem ter as vias aéreas asseguradas, bem como uma ventilação e oxigenação adequadas. As complicações decorrentes de um controlo ineficaz da via aérea podem incluir aspiração, hipoxemia, lesão das vias aéreas e até mortalidade. Por isso, é crucial antecipar a existência de uma via aérea difícil e uma intubação desafiante, de forma a prevenir estas complicações. Este estudo tem como objetivo identificar um preditor simples, de fácil aplicação e com elevada especificidade e sensibilidade para prever a dificuldade na intubação. Os cinco parâmetros avaliados foram: o teste da altura tiromentoniana (TMHT), a distância tiromentoniana (TMD), a classificação modificada de Mallampati (MPC), a circunferência do pescoço (NC) e o índice de Wilson (WS).
Métodos: Os cinco parâmetros foram usados na avaliação pré-operatória dos doentes quanto à possibilidade de intubação difícil, tendo sido calculado um índice de dificuldade de intubação. Foram determinados e comparados a especificidade, sensibilidade, valor preditivo positivo (VPP), valor preditivo negativo (VPN) e a área sob a curva (AUC) para cada um dos cinco parâmetros.
Resultados: O VPP do TMHT foi de 80%, da TMD de 40%, do MPC de 34,37%, da NC de 26,83% e do WS de 26,09%, respetivamente. O TMHT demonstrou uma especificidade de 97,75%, sensibilidade de 71,43%, VPN de 96,44% e uma precisão de 94,80%, com uma área sob a curva de 0,946.
Conclusão: O estudo concluiu que a altura tiromentoniana (TMHT) foi o melhor preditor entre todos os parâmetros avaliados, apresentando os valores mais elevados de sensibilidade, VPP, VPN, precisão e AUC. A classificação de Mallampati (MPC), a circunferência do pescoço (NC) e o índice de Wilson (WS)
