    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.

    Repair of complete atrioventricular canal defects: Early and midterm results and comparison of the left anterior leaflet augmentation technique with traditional technics
    (WILEY, 2021-01-01) Basgoze, Serdar; Yildiz, Okan; Ozturk, Erkut; Onan, Ismihan Selen
    Background Complete atrioventricular septal defects (CAVSD) include a variable spectrum of congenital malformations with different forms of clinical findings. We examined early and midterm outcomes, the need for reoperation, postoperative residual AV valve regurgitation, and other risk factors after various CAVSD repairs. Methods Between 2014 and 2018, we have performed 89 isolated CAVSD repairs. We retrospectively reviewed the patients' medical records. Patients were divided into three groups according to their repair techniques modified one patch repair (MP) (n = 16)

    Noninvasive monitoring of central venous oxygen saturation by jugular transcutaneous near-infrared spectroscopy in pediatric patients undergoing congenital cardiac surgery
    (TUBITAK SCIENTIFIC \& TECHNICAL RESEARCH COUNCIL TURKEY, 2020-01-01) Altun, Dilek; Dogan, Abdullah; Arnaz, Ahmet; Yuksek, Adnan; Yalcinbas, Yusuf Kenan; Turkoz, Riza; Sarioglu, Tayyar
    Background and aim: In patients undergoing congenital cardiac surgery, it is crucial to maintain oxygen demand-consumption balance. Central venous oxygen saturation (ScvO(2)) is a useful indicator of oxygen demand and consumption balance which is an invasive method. Near-infrared spectroscopy (NIRS) is a noninvasive, continuous monitoring technique that measures regional tissue oxygenation. NIRS that is placed over the internal jugular vein cutaneous area (NIRSijv) has the potential to show ScvO(2) indirectly. In this study, we aimed to determine the correlation between ScvO(2) with NIRSijv in pediatric patients undergoing congenital cardiac surgery. Materials and methods: Fifty children participated in the study. Four patients were excluded for the inability of internal jugular vein (IJV) catheterization due to technical difficulties. After anesthesia induction, NI RS probes were placed on the IJV site with ultrasound guidance for the measurement of continuous transcutaneous oxygen saturation. The catheter insertion was also done through the IJV from the other side using ultrasound guidance. Cerebral oxygenation monitoring was done using NI RS with a single pediatric probe placed on the right forehead. Values of NIRSijv, cerebral NI RS (NIRSc) and ScvO(2), were recorded at certain times until postoperative 24th hour. Results: Data were collected at 8 different time points. There was a significant correlation between ScvO(2) and NIRSijv in all measurement time points (r = 0.91), (p = 0.001). The mean bias between ScvO(2) and NIRSijv was 2.92\% and the limits of agreement were from 11\% to -5.2\%. There was a moderate correlation between ScvO(2) and NIRSc (r = 0.45), (13= 0.001). The mean bias between ScvO(2) and NIRSc was 2.7\% and the limits of agreement were from +26\% to -20\%. Conclusion: In this study, we found a strong correlation between ScvO(2) and NI RS measurements taken from the internal jugular vein site. Accordingly, continuous noninvasive monitoring with transcutaneous NIRSijv can be an alternative method as a trend monitor for the central venous oxygen saturation in pediatric cardiac patients undergoing congenital cardiac surgery.
