Noteworthy Effect of Hemoglobin on Short-Term Mortality and Extubation Time of Elderly Patients Undergoing OPCABG

Abstract

Objective: Interest in off pump technique has markedly expanded in recent years. It has been shown that peroperative complications and mortality rates are reduced with the off-pump coronary bypass grafting (OPCABG) technique, even in high risk elderly patient groups. This study aimed to evaluate the results of patients over the age of 65 who underwent OPCABG. Methods: This study included 116 patients aged 65 and over who underwent coronary artery bypass graft surgery (CABG). Patients’ datas were collected from digital database. Demographic and clinical data such as peroperative data, comorbidities, additional treatment requirements and discharge status of all patients were recorded. Results: The mean age of the patients was 67.97 ±3.40 years. The extubation time of the patients was 331.68 ±222.08 minutes. When the factors affecting the extubation time were evaluated, hemoglobin (p: 0.016) was found to be statistically significant. The mortality rate was found to be 5.17% (n:6). When survivors and non-survivors were compared, the differences in ejection fraction, extubation time, troponin and hemoglobin level were found to be statistically significant. Logistic regression analysis revealed statistical significance for ejection fraction (0.011), troponin (0.036), and hemoglobin level (0.036). The discrimination power of troponin value was determined to be more successful than other parameters (odds ratio 1.105, AUC: 0.755, p: 0.036). Conclusion: Our findings support that, when performed by an experienced surgical team, OPCABG can be safely and effectively utilized in patients above 65 years. Although hemoglobin was found to be effective on both extubation time and short-term mortality rate, troponin was found to be the most effective factor on mortality rate.
