What Is GHB Anyway?
Let’s face it, there are a whole bunch of street drugs out there that we as EMS caregivers should understand. While we can’t always be expected to identify the exact drug a patient has ingested. We do need to be able to predict a given drugs effect on the body. We should also be able to take a fair guess at
the identity of an ingested drug based on our evaluation of the patient’s physical presentation. GHB is one of those drugs that can be hard to nail down based on the physical signs. But it does leave some clues – if you know what your look for.
What Is It? : A Multi-Receptor Stimulant
GHB is short for gamma-Hydroxybutyric Acid, a naturally occurring substance produced by the central nervous system and found in small quantities in beef, wine and citrus fruits. It was first synthesized in a laboratory in 1874 but it wasn’t used in humans until 1960 when it was used in GABA receptor research and found to have a wide range of effects. In that year, scientists began testing GHB as an anesthetic and in the treatment of insomnia and depression.
The drug acts on both GABA and GHB receptors in the brain. Stimulation of GABA receptors has a sedative and analgesic effect. Stimulation of GHB receptors is primarily stimulatory. GHB also produces a biphasic release of Dopamine which produces euphoria. Understanding this multi-function aspect of GHB is key to recognizing the wide range of physical symptoms that are produced from a single GHB ingestion.
The Hallmark of GHB Overdose: Wave-like Altered Mentation
A patient experiencing a GHB high will have many symptoms similar to other drugs. But they’ll also have a unique progression of symptoms unlike any other single street drug. This becomes confusing for the emergency caregiver. GHB overdoses don’t follow a linear progression of symptoms They ride waves of symptoms. … Let me explain.
