Many are rarely used outside anesthesiology, but others are used commonly in various fields of healthcare.
The core element of the specialty is the study and use of anesthesia and anesthetics to safely support a patient's vital functions through the perioperative period.

Cocaine

Ester local anesthetics (such as procaine, amethocaine, cocaine, benzocaine, tetracaine) are generally unstable in solution and fast-acting, are rapidly metabolised by cholinesterases in the blood plasma and liver, and more commonly induce allergic reactions.
Topical cocaine can be used as a local numbing agent to help with painful procedures in the mouth or nose.

Benzocaine

It is given to patients during surgery to relieve pain and as an adjunct to an anaesthetic.

Tubocurarine chloride

In the mid-1900s, it was used in conjunction with an anesthetic to provide skeletal muscle relaxation during surgery or mechanical ventilation.

Anesthesia awareness

anaesthesia awarenessconscious sedation anesthesiaIntraoperative awareness
Another potentially disturbing complication where neuromuscular blockade is employed is 'anesthesia awareness'.
This is usually caused by the delivery of inadequate anesthetics (purposefully or accidentally) relative to the patient's requirements, resulting in patients waking up and becoming conscious during their procedures.

Hydromorphone

CNS depressants may enhance the depressant effects of hydromorphone, such as other opioids, anesthetics, sedatives, hypnotics, barbiturates, benzodiazepines, phenothiazines, chloral hydrate, dimenhydrinate, and glutethimide.

It also offers properties of sedation and this makes it a good analgesic component of anesthetic regimen during an operation.

Ketamine

However, its emergence as a club drug differs from other club drugs (e.g., MDMA) due to its anesthetic properties (e.g., slurred speech, immobilization) at higher doses; in addition, there are reports of ketamine being sold as "ecstasy".

Pancuronium bromide
