    The Changes with the New Legislations
    (2023) Bicakcioglu, Murat; Gedik, Ender
    Organ transplantation is the most important option for the treatment of end-stage diseases. However, there is a large difference between the number of patients on the waiting list and the number of transplants performed. The gradual increase in this difference creates ethical problems related to organ transplantation. Ethical problems and other limitations require organ transplantation to be controlled by legal regulations. In our country, organ transplantation practice is carried out under the supervision of the state. Organ Transplant Practice Regulation has been updated by being published in the Official Gazette dated 09.12.2022 and numbered 32008. Possible end-of-life decisions in brain death are stated in accordance with the conditions of our country. "In cases where brain death is diagnosed, the organ preservation protocols applied are terminated in the absence of family or legal guardian approval regarding organ donation. In case of organ donation by the family or legal guardian, the organ preservation protocols needed for donor care are continued during the period until the transplantation of the organ to the waiting patient", and a solution has been presented to the intensive care physicians for the prognosis of the cases that donated or could not be donated.In the regulation in which the prerequisites of the brain death diagnostic criteria are specified, it is stated that the central body temperature should be =36 degrees C. With the new regulation, end-of-life decisions on brain death and changes made in relation to central body temperature have brought convenience in the diagnosis and follow- up process.

    Ethics and Clinical Communications
    (2023) Yesiler, Fatma Irem; Gedik, Ender
    The diagnosis of brain death has medical, legal and ethical aspects. While the main determinant is the medical approach of the physician in terms of ethics, legal situations are also effective in the process. Non-harm, beneficence, respect for autonomy and justice are the principles that are widely accepted and form the basis of medical ethics. Understanding these principles is a must in order to talk about the ethics of brain death and organ transplantation. In the process of diagnosis and management of brain death, the physician should convey the process to the relatives of the patients in a clear and understandable language and in accordance with the educational-cultural levels of the relatives of the patients. The fact that the concept of brain death is misunderstood in the society or lack of knowledge creates social ethical problems. Special training should be given to health professionals for brain death awareness and early diagnosis, and their ability to resolve ethical problems should be strengthened. Human resources are of great importance in the diagnosis of brain death and in the process of organ transplantation from a cadaver. Communication skills are the mainstay of interaction within the clinic. Organ transplant coordinators should run the process smoothly by creating a bridge between the physician responsible for the case and the intensive care physicians. Such an approach will reduce ethical issues and ensure a successful diagnosis and donation process.

    A Comparison of Echocardiography and the Pressure Recording Analytical Method (PRAM) for Predicting Fluid Responsiveness after Passive Leg Raising
    (2021) Ozdemirkan, Aycan; Aitakhanoya, Manat; Gedik, Ender; Zeyneloglu, Pinar; Pirat, Arash; 0000-0002-7175-207X; ABI-2971-2020
    Objective: This study aims to assess the agreement between the cardiac index (CI) measured by pressure recording analytical method (PRAM) and transthoracic echocardiography (TTE) before and after the passive leg raise (PLR) maneuver. Methods: This is a prospective observational study in critically ill patients who were monitored with MostcareUp/PRAM (Vygon, Vytech, Padova, Italy). Cardiac index (CI) values and percent changes in CI values in response to PLR were recorded by TTE and PRAM. Results: Data of a total of 25 patients were collected. The median CI values that were calculated by TTE before and after PLR were 2.5 (1.2-4.7) L/min/m(2) and 2.9 (1.4-5.6) L/min/m(2), respectively. The median CI values that were calculated by PRAM before and after PLR were 2.5 (1.5-4.8) L/min/m(2) and 2.6 (1.7-5.7) L/min/m(2), respectively. There was significant correlations between the measured CI values both by TTE and PRAM before and after PLR (r=0.635, p=0.001 and r=0.610, p=0.001, respectively). The median percent changes in CI with TTE and PRAM were -0.13 (-0.7-0.4) and -0.11 (-0.5-0.5), respectively. Sixteen patients were determined as FR by TTE (64%) and 13 patients were determined as FR by PRAM (52%). The Kappa test showed moderate agreement between TTE and PRAM for predicting fluid responsiveness (k=0.595; p=0.002). The mean biases between the CI values measured by TTE and PRAM before and after PLR were 0.04 +/- 0.77 L/min/m(2) and 0.22 +/- 0.88 L/min/m(2), respectively. Conclusion: This study showed a significant correlation for CI values measured by both methods. For predicting fluid responsiveness there was agreement between the two methods after PLR.
