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.

Objective: The aim of this study was to determine the risk factors in atrial fibrillation (AF), which is the most common rhythm disorder observed after coronary artery bypass graft (CABG) surgery, and to show whether there is a correlation between C-reactive protein (CRP) and AF. Methods: A total of 250 patients who would undergo coronary artery surgery were retrospectively included in the study. Demographic data, peroperative and postoperative variables of all patients, daily CRP and AF follow-ups until the 6th postoperative day and treatment protocols of AF patients were recorded. Results: AF was detected in 43 (17.2%) of the patients who were followed up. It was found that there was a statistically significant relationship in the multivariate analysis between advanced age, hypertension (HT) and use of preoperative calcium channel blocker and AF (p<0.05). CRP values reached the highest value on the 2nd postoperative day. Although AF was seen in 14 patients (5.6%) in this period, no relation was found between increased CRP levels and the development of AF (p>0.05). It was observed that the length of intensive care and hospital stay of patients with AF was statistically significantly longer (p<0.05). Conclusion: It was found that older hypertensive patients who preoperatively used calcium channel blocker had a higher risk of developing AF. Duration of ICU and hospital stay was longer, and no correlation was found between AF and CRP. [ABSTRACT FROM AUTHOR]

Objective: Ventilator-associated pneumonia (VAP) are among common infections encountered in intensive care units. The high mortality rate is important due to prolonged hospital stay and increased hospital costs. In this study, we aimed to determine the risk factors associated with VAP in patients who had undergone open heart surgery. Method: In this study, a total of 599 patients (178 female, and 421 male) who underwent elective open heart surgery were prospectively included in this study. Patients who could not be extubated after 48 hours were divided into two groups. Group 1: Patients with clinical suspicion of VAP and bacterial growth in their endotracheal aspirates (ETA) (n=29) Group 2: Control group (n=570). Results: In univariate analysis, age, Chronic Obstructive Pulmonary Disease (COPD) Pulmonary Hypertension (PHT), history of myocardial infarction (MI), low ejection fraction (EF), prolonged cross- clamp and pump times, inotropic support, presnce of intra-aortic balloon pump (IABP) and use of hemofiltration, atrial fibrillation, reintubation, enteral nutrition with nasogastric tube, reoperation, neurologic dysfunction, steroid use, blood and blood product use, hypoalbuminemia and presence of decubitus ulcer were detected as risk factors for VIP. According to logistic regression analysis duration of intubation longer than 72 hours, reintubation, COPD, previous MI, steroid use, AF neurologic dysfunction were determined as independent risk factors for VAP. Conclusion: In the patient population consisting of patients with cardiac surgery, keeping the invasive mechanical ventilator support as short as possible, reducing the need for reintubation by extubation in optimal time, ensuring complete haemodynamic stability, preoperative preparation of the patient preoperatively, prevention of postoperative haemodynamic instability during surgery, and reduction of VAP.

Objective: This study aims to analyze the effects of two different positive end- expiratory pressure (PEEP) levels during single lung ventilation with low tidal volume (TV) on respiration and hemodynamics in patients undergoing thoracotomy. Material and Methods: After the Hospital Education Planning Board approval and written consent were obtained 40 patients scheduled for thoracotomy were enrolled in the study. When all patients were intubated with double- lumen endotracheal tube and one-lung ventilation (OLV) was initiated, the patients were randomized into two groups. Group 1 (n: 20) consisted of patients who underwent lung ventilation with 6 ml/kg TV and 5 cm H2O PEEP; and Group 2 (n: 20) consisted of patients who underwent lung ventilation with 6 ml/ kg TV and 10 cm H2O PEEP. Arterial blood gas samples were obtained from the patients during the study, and mean arterial pressure, heart rate, partial oxygen pressure (pO2), partial carbondioxide pressure (pCO2), peak airway pressures (PİP), plateau pressure values were recorded at 7 different time points namely T0: Supine position, before the induction, T1: double lung ventilation after induction, T2: OLV 15 minutes, T3: OLV 30 minutes, T4: OLV 45 minutes, T5: pre-extubation, supine position, T6: Postoperative 6th hour. Results: Mean arterial pressure and heart rate values were significantly lower at T1, T2, T3 ve T4 time points in Group 2; however, this decrease was within physiological limit. Group 2 patients had significantly higher PaO2 and lower PaCO2 values. At time points of T2, T3 and T4 when the patients were under OLV, PiP and plateau pressures in Group 2 patients were significantly higher (p<0.05). Conclusion: It was concluded that delivery of low tidal volume and 10 cm H2O PEEP to the ventilated lung during thoracotomy made positive contributions to oxygenation without any adverse effects on hemodynamic, and respiratory mechanisms.

Objective: The aim of this study is to evaluate the effects of single dose insulin, given prior to reperfusion, in patients undergoing coronary artery bypass surgery (CABG)., Methods: One hundred and twenty patients were prospectively randomized to be given either insulin (Group 1;n=60), or saline (Group 2;n= 60). Blood samples were taken 15 minutes before the reperfusion and insulin was given (0.3 IU/kg) to the patients in Group 1. Arterial and coronary sinus blood samples were taken, after the release of aortic cross-clamp (0. min), and 5th -10th -15th minutes of reperfusion. Arterial and coronary sinus lactate and glucose levels, postoperative insulin, inotropic and intraaortic balloon pump requirements; need for defibrillation and postoperative dysrhythmia, creatine kinase- MB (CPK-MB) levels, and length of stay in intensive care unit (ICU) and hospital were compared., Results: In Group 1, arterial lactate levels were found to be lower at 0.min, coronary sinus lactate levels were found to be lower at 0-5-10th minutes of reperfusion compared to Group 2. Similarly, defibrillation, glucose, postoperative insulin and inotrop requirements, postoperative arrhythmia and length of ICU stay were lower in Group 1. The CPK-MB levels and length of hospital stay were similar in all patients., Conclusions: We conclude that single dose insulin given before the reperfusion period, has positive perioperative effects. Therefore it can be used in patients undergoing CABG surgery to decrease ischemia-reperfusion injury.
