Abstract

Background

Severe odontogenic infections requiring surgical drainage pose significant airway management challenges. This study aimed to compare perioperative characteristics and clinical outcomes between patients managed with conventional laryngoscopy versus awake fiberoptic intubation, to identify factors associated with the selection of airway management technique, and to determine predictors of hospital length of stay.

Methods

This single-center retrospective study included 85 adult patients who underwent surgical drainage of severe odontogenic infections under general anesthesia between 2015 and 2024. The primary objective was to identify factors associated with awake fiberoptic intubation selection. Secondary objectives included comparison of perioperative outcomes and identification of predictors of hospital discharge. Multivariable logistic regression and Cox proportional hazards modeling were used.

Results

Of 85 patients, 60% were managed with AFOI. Multivariable analysis identified trismus (OR = 6.67, 95% CI 1.53, 39.53, p = 0.010) and higher BMI (OR = 1.15, 95% CI 1.03, 1.33, p = 0.013) as independent predictors of AFOI selection. AFOI patients experienced more complex postoperative courses, with intraoperative tracheostomy, ICU admission, and septic shock occurring exclusively in this group. Spontaneous ventilation postoperatively was associated with earlier discharge (HR = 2.14, 95% CI 1.23, 3.73, p = 0.007), while septic shock (HR = 0.26, 95% CI 0.07, 0.91, p = 0.036) and lower BMI (HR = 0.95, 95% CI 0.90, 1.00, p = 0.040) were associated with delayed discharge.

Conclusion

AFOI was preferentially selected for anatomically complex odontogenic infections based on objective criteria, particularly trismus and elevated BMI. The ability to achieve spontaneous ventilation postoperatively serves as a key prognostic indicator, while septic shock is strongly associated with prolonged recovery. These findings support evidence-based airway management protocols and early identification of high-risk patients to optimize outcomes in this challenging population.

Resumo

Introdução

Infecções odontogênicas graves que requerem drenagem cirúrgica representam desafios significativos para o manejo das vias aéreas. Este estudo teve como objetivo comparar características perioperatórias e desfechos clínicos entre pacientes manejados com laringoscopia convencional versus intubação fibroóptica acordada, identificar fatores associados à seleção da técnica de manejo das vias aéreas e determinar preditores do tempo de internação hospitalar.

Métodos

Este estudo retrospectivo unicêntrico incluiu 85 pacientes adultos submetidos à drenagem cirúrgica de infecções odontogênicas graves sob anestesia geral entre 2015 e 2024. O objetivo primário foi identificar fatores associados à escolha da intubação fibróptica acordada. Os objetivos secundários incluíram comparação dos desfechos perioperatórios e identificação de preditores de alta hospitalar. Foram utilizados regressão logística multivariável e modelo de riscos proporcionais de Cox.

Resultados

Dos 85 pacientes, 60% foram manejados com intubação fibróptica acordada (AFOI). A análise multivariável identificou trismo (OR = 6,67; IC 95% 1,53–39,53; p = 0,010) e maior índice de massa corporal (OR = 1,15; IC 95% 1,03–1,33; p = 0,013) como preditores independentes da escolha de AFOI. Pacientes submetidos à AFOI apresentaram cursos pós-operatórios mais complexos, com traqueostomia intraoperatória, admissão em UTI e choque séptico ocorrendo exclusivamente nesse grupo. Ventilação espontânea no pós-operatório esteve associada à alta hospitalar mais precoce (HR = 2,14; IC 95% 1,23–3,73; p = 0,007), enquanto choque séptico (HR = 0,26; IC 95% 0,07–0,91; p = 0,036) e menor índice de massa corporal (HR = 0,95; IC 95% 0,90–1,00; p = 0,040) estiveram associados à alta tardia.

Conclusão

A AFOI foi preferencialmente escolhida para infecções odontogênicas anatomicamente complexas com base em critérios objetivos, particularmente trismo e índice de massa corporal elevado. A capacidade de alcançar ventilação espontânea no pós-operatório mostrou-se um importante indicador prognóstico, enquanto choque séptico esteve fortemente associado à recuperação prolongada. Esses achados sustentam protocolos de manejo das vias aéreas baseados em evidências e a identificação precoce de pacientes de alto risco para otimizar desfechos nessa população desafiadora.
