Objective: This study was planned to evaluate effectiveness of cardiac surgery score (CASUS) system used for the prediction of mortality after the cardiac surgery and to compare it with EuroSCORE, a tested and approved method. Method: Fifty patients over the age of 18 who came to the intensive care unit (ICU) after open heart surgery and stayed in the ICU for more than 48 hours were prospectively included in the study. After the preoperative EuroSCORE evaluation of the patients, CASUS scoring systems were used for risk scoring from postoperative 0 day to the service or up to the 6th postoperative day (or possible mortality) in patients whose stay in ICU was prolonged. We evaluated the place of both models in the prediction of ICU mortality. Results: The study was conducted with 50 patients- 21 female, 29 male-, aged between 19 and 79 years (mean age: 60.38±12.50). Five (10%) cases exited.The areas under the ROC curve were estimated as follows: EuroSCORE, 45.3%; and for CASUS 0,1, and 2. day scores AUCs of ROC curve were 66,9%, 64,7%, and 79,8%, respectively. The CASUS 2nd day score was found to be valuable in predicting mortality (p<0.01). A statistically significant relationship was observed between the days of stay in the ICU and mortality. Conclusion: Our results show that the rate of the accurate prediction of mortality of CASUS is insufficient on postop 0th and 1st day; however CASUS score on postoperative 2nd day has sufficient.predictive accuracy EuroSCORE is not found effective in the prediction of mortality. It is observed that if the duration of stay in ICU is prolonged, it statistically significantly increases the risk of mortality. [ABSTRACT FROM AUTHOR]

Objective: TThe application of mechanical support devices such as extracorporeal membrane oxygenatior (ECMO) has increased with the increase in complex cardiac surgery operations in congenital heart diseases. Despite significant advances in ECMO techniques and methods, the prognosis is still poor. The aim of this study is to show the relationship between organ dysfunction and mortality in patients with veno-arterial (VA) ECMO after pediatric cardiac surgery. Method: Sixty-three patients in the pediatric cardiac ICU who had VA-ECMO and followed up up to 48 hours in our clinic, were retrospectively included in the study and two groups were formed as follows: Group 1: Patients exited within 30 days (n: 47), Group 2: Survived patients (n: 16). Along with the demographic data of the patients, ECMO placement time, creatinine, BUN (blood urea nitrogen), ALT (alanine aminotransferase), AST (aspartate aminotransferase), bilirubin, albumin and platelet counts were recorded. Results: While 36 patients (57.1%) left ECMO in our study group, 16 of these patients (16/63,25.4%) were discharged. A total of 47 patients (47/63, 74.6%) died. Although the number of patients who underwent univentricular repair (26/47,55.31%) in Group 1 was higher (n=5:31.25%) than Group 2, this difference was not significant (p>0.05). Postoperative ECMO was implanted in 27 patients (57.44%) in Group 1 and 4 patients (31.25%) in Group 2, and this difference was statistically significant (p<0.02). While levels of creatinine, BUN, ALT, AST were higher in Group 1 patients who had higher mortality rates, albumin and platelet values were lower than Group 2 (p<0.05). Conclusion: It has been determined that organ dysfunction parameters were found to be effective in showing mortality, mortality rates were higher among patients in whom ECMO was placed postoperatively.
