Investigation of the Effect of Acute to Chronic Glycemic Ratio on the Development of Postoperative Pneumonia After Stanford Type A Acute Aortic Dissection Surgery

Aim: A critical clinical condition called acute Type A aortic dissection (ATAAD) necessitates quick surgical action. Other significant issues include the emergence of postoperative pneumonia and various organ failures. We sought to determine how well the ratio of admission blood glucose (ABG) to estimated average glucose (eAG) might be used to anticipate postoperative pneumonia following ATAAD surgery. Materials and Methods: The study comprised patients who underwent ATAAD surgery between January 2016 and January 2022. In the postoperative phase, patients were divided into two groups: Group 1 for those who did not acquire pneumonia and Group 2 for those who did.Results: The study involved 124 patients in total. Group 1 [N = 92, median age = 51 (32 to 80) years] consisted of those who did not acquire postoperative pneumonia, but Group 2 [N = 32, median age = 53 (30 to 77)] did. ABG/eAG ratio and ventilation time were found to be independent predictors of postoperative pneumonia by multivariate analysis [(OR: 0.886, CI 95%: 0.695-0.990, P=0.009) and (OR: 1.114, 1.030-1.542, P=0.023)].Conclusion: We demonstrated that ABG/eAG ratio, calculated at admission time, is a significant predictor of the development of postoperative pneumonia.
