The main causes of loss of consciousness in a healthy person

**First**. Loss of consciousness is often caused by the use of vasoactive drugs, sometimes painkillers, but more often vasoconstrictors (adrenaline, ephedrine, pentamine). Rapid heartbeat and constriction of blood vessels lead to their spasm, which causes a temporary cessation of cerebral blood flow.

**Second**. In other situations, the cause of loss of consciousness is a temporary inhibition of the activity of the thermoregulation center located in the hypothalamus. As a rule, this occurs with temperature shock. Chills and trembling distract the patient's attention, causing a short-term loss of consciousness.

The third reason may be increased intracranial pressure. This occurs for a number of reasons (such as brain damage or fluid leaking into the ventricular system) and is often accompanied by severe vomiting or increased intraocular pressure.

The fourth reason is severe pain syndrome of a psychogenic nature (as a result of the action of neuroses or psychoses).

Pathogenesis. Clinical picture. Treatment After bringing the patient into a stable lateral position, his stable long-term bradycardia and drop in blood pressure continue until collapse, complete decompensation of the cardiovascular system, multiple organ failure,
