Hemodynamic disturbance is a common condition in many different situations such as shock, heart failure, myocardial infarction. These are all dangerous conditions that need to be treated promptly. The drug used to correct hemodynamic disturbances is a vasopressor.

In order to use vasopressors correctly, it is necessary to understand the role of the above factors in the clinical setting, and at the same time understand the pharmacological effects on the above factors of the intended vasopressors.

Vasopressors in cardiovascular emergency help restore tissue perfusion, enhance tissue oxygenation in patients in shock; raised mean blood pressure to increase cardiac index and volume without affecting oxygen consumption and metabolic acidosis.

Beta-blockers antagonize beta-adrenergic receptors and are used primarily in the treatment of hypertension, heart failure, tachyarrhythmias, and angina. In addition to cardiovascular disorders, beta-blockers are also used in the treatment of anxiety, migraines, glaucoma, tremors, hyperthyroidism, and many other disorders. There are beta-blockers on the market such as: Bisoprolol Metoprolol, Carteolol, Propranolol, Sotalol, Carvedilol, Labetalol... Due to their diversity and widely used in the treatment of cardiovascular diseases, leading to risk Poisoning occurs with drugs of this group due to overdose.

Commonly prescribed for people with blood pressure and heart problems, Levonor is used to treat low blood pressure or shock with normal or high cardiac output. However, in order for the drug to be effective in the treatment process, patients need to know the information about the drug.

Dobutamin BFS belongs to the group of cardiovascular drugs, specialized in the treatment of heart failure due to pathology and surgery. With the drug of the same name, Dobutamin helps to contract the heart muscle, increase the heart rate and help the heart pump blood throughout the body.

Vasopressors are drugs that play a very important role in cardiovascular emergency. To effectively use vasopressors, pharmacists need to understand the pharmacological effects of the drugs and prescribe them appropriately in specific situations.

Septic shock reduces tissue perfusion, increases cardiac output, and carries a high risk of mortality. In the treatment of shock, vasopressors are the initial choice to achieve mean blood pressure and improve tissue perfusion.

Vasoconstrictors and inotropes are general emergency drugs and are indicated for use in the treatment of shock. The use of these drugs helps to quickly restore hemodynamic status, maintain blood pressure and ensure the patient's life while waiting for the causes of shock to be resolved and for the organ systems to recover.

The melting ice block surface sign on plain radiographs refers to the appearance of a reversing pulmonary infarction on plain films and CT, which looks like an image of melting ice block surface from the outside inwards.

Hypovolemic shock is a condition of decreased intravascular volume leading to circulatory failure in which there is a decrease in systemic tissue perfusion and/or an imbalance in blood flow distribution leading to inadequate oxygen and nutrient delivery to tissues, resulting in a decrease in total cellular oxygenation. Tissue hypoperfusion occurs before there is evidence of hypotension.
