    Background and Aim of the Study Transfusion-associated hyperpotassemia is a serious complication of packed red blood cell (PRBC) transfusion after congenital cardiac surgery. Our study aimed to identify risk factors and potential preventive measures of transfusion-associated hyperpotassemia in neonates and infants after congenital cardiac surgery. Methods Pediatric patients who underwent congenital cardiac surgery and need transfusion were enrolled in this prospective study. The potassium concentration of PRBC was checked from the sample taken from the segment. The volume of transfusion, age of PRBC, potassium concentration of unit were recorded. The estimated increment of potassium level in patients after PRBC transfusion was calculated. Results Seventy-four individual patients, 95 distinct transfusions, 112 blood products were evaluated. The mean age of the blood unit was 3.8 +/- 1.4 days. The mean potassium concentration in the PRBCs was 9.9 +/- 2.4 mmol/L. A weak correlation was observed between the potassium value of the PRBC and the age of PRBC (p = 0.049, r = 0.2, y = 0.24 x x + -0.68). There was a weak correlation between the potassium value of PRBCs and the age of the unit (p < 0.001, r = 0.37, y = 2.8 x x + -3.6). Conclusions Before transfusion, even PRBC is fresh, measuring the potassium level of PRBC and the potassium that will be given to the pediatric patient with transfusion can prevent transfusion-related hyperpotassemia and related complications. Otherwise, high potassium levels, which may be overlooked despite being fresh, may cause serious complications, even cardiac arrest, especially in neonates and infants.

    Ebstein's Anomaly
    (GAZI UNIV, FAC MED, 2018-01-01) Arnaz, Ahmet; Dogan, Abdullah; Oktay, Ayla; Yalcinbas, Yusuf; Turkoz, Riza; Saygili, Arda; Sarioglu, Ayse; Sarioglu, Tayyar
    Objectives: In this study, it is aimed to evaluate the operations performed for Ebstein `s anomaly retrospectively. Study design: Between July 2003 and February 2018, the medical records of 13 patients who were operated on with the diagnosis of Ebstein's anomaly were reviewed retrospectively according to the clinical symptoms, surgical procedure, and postoperative follow-up. Results: Of the thirteen patients, 46.2\% (n = 6) were female and 53.8\% (n = 7) were male. The mean age of the cases is 13,15 +/- 11,07 years (2-31 years). Preoperative echocardiographic evaluations revealed severe tricuspid regurgitation in 92.3\% (n = 12) of the patients. In these patients, tricuspid valve replacement was performed in 4, tricuspid valve plasty in 5, Cone reconstruction in 2, and cava-pulmonary shunt with tricuspid valve plasty in 2 were performed. Patients were followed for an average of 6.31 +/- 3.40 (1-14 years). Atrial septal defect closure in 53.8\% (n = 7) patients and mitral valve replacement in 7.7\% (n = 1) patients were performed due to additional anomalies. Atrial fibrillation/flutter was present in 23.1\% of the patients and ablation procedure was applied to these three patients. Conclusion: Long-term clinical follow-up is required for the signs and symptoms of heart failure, arrhythmia, cyanosis and other related findings both in operated and non-operated patients with Ebstein's anomaly.
