Final answer:
Sympathomimetic toxidrome is characterized by signs such as tachycardia, mydriasis, hypertension, hyperthermia, diaphoresis, agitation, and seizures, indicative of excessive sympathetic nervous system activity due to substances that stimulate adrenergic receptors.
Step-by-step explanation:
Sympathomimetic Toxidrome: Signs and Symptoms
Sympathomimetic toxidrome is characterized by a set of signs and symptoms that reflect an overstimulation of the sympathetic nervous system. Here is a direct answer in 2 lines about its presentation: Increased heart rate, dilated pupils, elevated blood pressure, agitation, seizures, hyperthermia, and excessive sweating.
Sympathomimetic toxidrome occurs when there is excessive sympathetic nervous system activity, generally due to the overuse or overdose of sympathomimetic drugs. These drugs mimic the action of the sympathetic neurotransmitters like norepinephrine and epinephrine. Symptoms arise as a result of increased stimulation of adrenergic receptors throughout the body.
The classic signs and symptoms of this toxidrome include:
Other associated symptoms may include anxiety, delusions, hallucinations, and paranoia. Management of the condition involves supportive care, sedation, cooling measures for hyperthermia, and sometimes specific antidotes.
There are several causes of sympathomimetic toxidrome, including but not limited to:
By recognizing these signs and symptoms early, proper and rapid medical intervention can be initiated.
