2.2. The goal of the program. Improvement of organ-substituting technologies in the treatment of heart and respiratory failure.
2.3. Objectives of the program. Objective 1. To study the restoration of organ function during implantation of extracorporeal membrane oxygenation (ECMO), as an organ replacement, in cardiac and/or respiratory failure.
Subtask 1.1. Evaluation of the recovery of organ function during ECMO using extracorporal hemo correction procedure.
Subtask 1.2. Evaluation of the normalization of the organism's immune response and restoration of organ function when conducting ECMO using the extracorporeal cytokine adsorber.
Subtask 1.3. Evaluation of the normalization of the organism's immune response and restoration of organ function when conducting ECMO using the extracorporeal hemoperfusion cartridge.
Objective 2. To study the results of applying organ-substituting technologies in the treatment of sepsis.
Subtask 2.1. Assessment of the recovery of organ function in the application of extracorporal hemo correction in septic patients.
Subtask 2.2. Evaluation of the normalization of the organism immune response and restoration of organ function when using the extracorporeal cytokine adsorber in septic patients.
Subtask 2.3. Evaluation of the normalization of the organism's immune response and restoration of organ function when using the extracorporeal hemoperfusion cartridge.
In this study, will be developed methods to restore the function of affected organs after implantation of ECMO and patients with sepsis in combination with extracorporeal hem correction, which will improve the results of surgical treatment of patients with end-cardiac and respiratory failure.
New methods developed to restore the function of affected organs after implantation of mechanical support devices and patients with sepsis will be of great importance both for Kazakhstan and for countries with similar categories of patients, which will improve the efficiency of surgical treatment and reduce the level of complications and mortality.
Clinical research data will form the basis of practical protocols for extracorporeal membrane oxygenation (ECMO) and patients with sepsis, which will improve organ repair, reduce postoperative complications, improve quality of life and reduce mortality after surgery.
Research methods and ethical issues Patients before implantation of ECMO and/or patients with sepsis will be enrolled in the study after giving a written, signed informed consent.
The participants will be randomized into 3 groups:
* Intervention group #1 a cytokine adsorber will be used (30 patients): patients on ECMO - subgroup A; septic patients - subgroup B.
* Intervention group #2 an extracorporeal hemoperfusion cartridge will be used (30 patients): patients on ECMO - subgroup C, septic patients - subgroup D.
* Control group #3 without using extracorporeal adsorber (30 patients): patients on ECMO subgroup - E, septic patients - subgroup F.
The investigators will collect demographic, clinical, and laboratory data about patients before, during, and after the operation The incidence of early cellular or humoral rejection, length of ventilation, ICU and hospital stay, the use of vasopressors and inotropes in the perioperative period, and incidence of perioperative complications and survival will be documented.
The level of cytokines (IL-1, IL-6, IL-8, IL-10, tumor necrosis factor-alfa) and complements before, during, and after the use of ECMO, patients with sepsis will be determined if the investigators find the relevant differences between the two groups in clinical variables.
