Modern critical care medicine and cardiac surgery revolve around high-tech solutions that quickly replace the functions of vital organs. One of the most dangerous methods of invasive support of the cardiovascular and circulatory systems is extracorporeal membrane oxygenation (ECMO)..
This method allows doctors to gain time - the most valuable resource for acute cardiac or respiratory failure, allowing pathologically affected organs to heal under the hour of intensive treatment.
The essence of the method is that spheri zastosuvannya.
The principle of ECMO lies in the collection of venous blood from the patient’s bed, which is saturated with acid, removed carbon dioxide and then returned to the bloodstream using a special pump.. In exchange for unit ventilation devices (SHVL), which do not pump gas into the airway, the ECMO creates a non-median gas exchange in the tissue area, bypassing.
Clinical indications for stagnation:.
Severe gastrointestinal insufficiency: distress syndrome, serious pneumonia, if the airway does not provide adequate oxygenation;
Acute heart failure: cardiogenic shock, acute myocarditis, complications after myocardial infarction;
Cardiac surgery: supporting blood flow during complex operations on the open heart and in the postoperative period;
Transplantology: supporting patients during the period of obtaining donor organs (heart and legion).
Main components of the EKMO system.
The complex infrastructure of extracorporeal support includes a number of high-precision elements that function as a single closed circuit:.
Blood pump (pump): the role of the heart plays a role in ensuring stable blood circulation throughout the circuit;
Membrane oxygenator: “piece legen”, where through special penetrating membranes the blood is enriched with acids and CO evacuation?
Heat exchanger: maintains proper blood temperature before moving to the patient’s body;
Specialized cannulas: biologic lines that ensure the collection and circulation of blood through large vessels;
Sensor monitoring system: monitors tension, oxygenation level, gas exchange indicators and blood flow parameters in real time.
Current high-tech ECMO systems allow both veno-venous (for supporting the legs) and veno-arterial circuits (for one-hour support of the heart and leg), which ensures flexibility in the choice of therapeutic.
Technology evolution and current trends.
Over the past few years, extracorporeal support technologies have been recognized by the global transformations. Since previously ECMO was mainly used in the inpatient departments of highly specialized cardiocenters, the equipment has now become more compact, mobile and safe for the patient.
By completely optimizing the hemostatic coatings of the internal surfaces of the circuit, the risk of thrombosis and ignition reactions in the body was significantly reduced. This made it possible to expand the deployment of mobile medical teams that cannulate and transport patients in critical care between medical facilities.
