RESUMO
Objectives: Acute upper airway obstruction is a critical medical condition that presents considerable challenges to anesthesiologists. This study aims to provide a formal report on the incidence and outcomes of perioperative complications, as well as the factors that influence unstable intraoperative hemodynamics. Methods: This retrospective study reviewed patients aged 18 years and older who underwent emergency tracheostomy between January 2013 and October 2021. Data on perioperative complications and outcomes within the first 24 hours and 7 days after surgery were subjected to analysis. Descriptive and multivariate analyses were used to examine the results. Results: A total of 253 patients were included in the study. The mean age was 61.5 ± 12.9 years. Malignancy was detected in 78.3% of the patients. General anesthesia was administered to 43.9% of the patients. The incidence of intraoperative complications was 51.8%, with hypotension and hypertension occurring in 30.4% and 22.5% of the cases, respectively. Desaturation and cardiac arrest were observed in 4.7% and 0.8% of the patients, respectively. The mortality rate at 7 days after surgery was 1.6%. Multivariate analysis revealed that monitored anesthesia care [adjusted odds ratio (OR) = 1.80; 95% confidence interval (CI): 1.08-3.00] and hypertensive patients (adjusted OR = 1.70, 95% CI: 1.01-2.86) were associated with unstable intraoperative hemodynamics. Conclusions: Cardiovascular instability represented the majority of the complications observed. Monitoring anesthesia care and hypertension were significant prognostic factors for unstable intraoperative hemodynamics. We recommend extensive communication between ear, nose, and throat surgeons and anesthesiologists to determine the appropriate choice of anesthesia.
