Cardioplegia Ischemic

Cardioplegia ischemic.
K., carried out by stopping the coronary circulation.

Ischemic cardioplegia is a method of stopping the heart by stopping the coronary (arterial) circulation. Used in cases where it is necessary to undergo long-term heart surgery.

The essence of the method is that a clamp is applied to the aorta, and special catheters are placed on the coronary arteries, which are filled with a special solution. This solution is supplied under pressure and completely blocks the coronary arteries. Thus, coronary blood flow is completely stopped and the heart stops working.

This method allows long-term heart surgeries to be performed without risking the patient's life. However, cardioplegia can be dangerous for patients with heart disease, as it can cause myocardial ischemia. Therefore, before performing the operation, it is necessary to conduct a thorough examination of the patient and ensure that there are no contraindications.

Overall, cardioplegia is an important method of cardiac arrest during long-term cardiac surgery, but requires careful preparation and evaluation of the patient.

Cardioplegia is a method of maintaining heart function during surgical interventions. Depending on which method of cardioplegia is used, it can be partial or complete. With partial cardioplegia, the heart does not stop working completely, but only part of the myocardium remains at rest. However, this can lead to disruption of the blood supply to the heart, which is life-threatening for the patient. Complete cardioplegia is usually used only in cases where complete cessation of blood flow is required, such as during open heart surgery. Ischemic cardioplegia. The essence of this method is to create an artificial myocardial infarction.

Cardioplegation, or extubation, is a process during which doctors cut off the blood supply to the heart. This is done as part of a surgical or invasive treatment in order to save the patient's life after the procedure and keep the heart healthy. Many people believe that cardioplegation provokes heart problems in the future, but in fact the heart muscle does not die from cardiac arrest because it has a supply of oxygen. When the blood circulation is turned off, the heart continues to beat thanks to the remaining amount of oxygen, even if the person is in a state of clinical death.

The body was not designed for this state throughout the existence of our species, so when the body leaves this state, it loses the ability to function normally. This usually leads to heart rhythm disturbances and other consequences. Also, according to technology, two types of cardioplegia are distinguished:

1. Artificial - this type of cardioplegia includes preoperative preparation carried out in the last months before the operation or the day of its implementation; artificial administration of drugs (without the possibility of exiting it); cessation of blood circulation. 2. Autoplegia - usually used to treat ascites, due to the fact that when using the mechanism of pumping fluid from the abdominal cavity, hemodynamic disturbances occur; as a result, it becomes possible to use anesthesia without mechanical ventilation (artificial ventilation), which avoids a direct effect on blood circulation. If you have the technology and medications, you can turn off the blood even for yourself. However, usually artificial cardioplegation is performed during surgical operations in the thoracic and brachial zone, when it is possible to evacuate all the blood from the pericardial cavity (anatomical space separated by a thin membrane between the pericardial membranes of the myocardium), as this prevents the development of complications.
