Elimination of factors preventing early extubation (EE) is essential to reduce ventilation time and realize preventive and therapeutic measures. Objective. To study intra- and postoperative risk factors affecting EE. Material and methods. A retrospective cohort study included 2254 patients over 18 years old who underwent open cardiac surgery in 2019 year. To establish independent risk factors associated with ventilation time, we analyzed 96 perioperative parameters in 900 patients. In this article, we present analysis of 33 intraoperative parameters and 25 postoperative parameters. Results. We created 2 models to characterize intra- and postoperative periods using univariate and multivariate logistic regression analysis. Each model was characterized by high predictive accuracy, sensitivity and specificity. As a result, independent risk factors associated with ventilation time and providing EE were identified. Regression coefficient was calculated for each factor to predict EE. Conclusion. Research of risk factors influencing ventilation time allowed a personalized approach to each patient regarding individual risk and possibility of EE.
