Humans are warm-blooded animals, capable of maintaining body temperature thanks to the balance of heat generation and heat loss. When there is a disorder in body temperature balance, it increases too high, affecting metabolism, disrupting vital activities, and endangering life.

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.

Distributive shock is a severe reduction in vascular resistance that exceeds the compensation of increased cardiac output. Shock causes systemic tissue hypoperfusion, imbalance of tissue oxygen supply and demand, and tissue hypoxia.
