Açık kalp cerrahisi geçiren 80 yaş üstü hastalarda Geriatrik Nutrisyonel Risk İndeksinin mortalite oranını tahmin edebilme gücü

Abstract

Purpose: This retrospective study aimed to determine the predictive power of the geriatric nutritional risk index, calculated using the preoperative albumin value of patients over 80 years old who underwent open-heart surgery, in relation to the postoperative mortality rate.
 Materials and Methods: A total of 22 patients (13 males, 9 females; mean age: 82.1±2.4 years; range, 80-88 years) who underwent open elective heart surgery for coronary bypass and heart valve replacement between July 2019 and September 2022 were retrospectively analyzed using the geriatric nutritional risk index. Based on this index, two distinct groups were formed. Values 98 and below were considered risky, and values 99 and above were considered risk-free. There were 6 patients in the risk group. The other 16 patients were in the risk-free group. All patient groups were compared on the basis of surgical procedures, age, gender, body mass index (kg/m2), diabetes, hypertension, atrial fibrillation, smoking, and operative characteristics.
 Results: In the study, 6 risky (27.3%) and 16 risk-free (%72.7) patients were examined according to the geriatric nutritional risk index and the mortality rate was found to be high (%66.7) in the risky group. The patients in the risk group had lower body mass index and albumin values (25.0±1.8 and 30.1±2.4) compared with the risk-free group (28.1±2.4 and 36.7±3.1). In addition, the mean extubation values were high (11.2±4.2). No significant difference was found between the other parameters and the presence of risk.
 Conclusion: Before undergoing open heart surgery, the Geriatric Nutritional Risk Index can strongly predict postoperative mortality rates.
