Anesthetic Agents

Anesthetic Agents

Any drug used to induce a loss of sensation (with or without unconsciousness).

Adjunct

Additional agents that enhance the effects of anesthetics, including sedation, muscle relaxation, and analgesia.

Balanced Anesthesia

The goal of using a combination of anesthetic agents and adjuncts to achieve optimal anesthesia.

Route of Administration

The method by which anesthetic agents are delivered, such as injectable, oral, or inhalant.

Timing

Classification of anesthetic agents based on their use as premedication, induction, or maintenance agents.

Principal Effects

The main outcomes of anesthetic agents, categorized as local or general anesthetics.

Pharmacokinetics

The study of how drugs are absorbed, distributed, metabolized, and excreted in the body.

Pharmacodynamics

The study of the effects of drugs on the body and their mechanisms of action.

Agonist Drug

A substance that activates a receptor to produce a biological response.

Antagonist Drug

A substance that blocks or dampens the biological response by binding to a receptor without activating it.

Dose Dependent

The relationship between the dose of a drug and its effects, which can be desirable or undesirable.

Analgesia

The inability to perceive pain, which is crucial during painful procedures.

True Analgesics

Drugs that provide pain relief; many anesthetics do not qualify as true analgesics.

Balanced Anesthesia

The practice of using multiple drugs to achieve desired effects while minimizing side effects.

Pre-Anesthetic Medication

Drugs given before anesthesia to prepare the patient and reduce anxiety or adverse effects.

Anticholinergics

Non-controlled drugs used to prevent bradycardia and decrease salivary secretions.

Atropine

An anticholinergic drug that acts quickly to prevent bradycardia and reduce secretions.

Glycopyrrolate

An anticholinergic drug with a longer duration of action than atropine.

Vagus Nerve

A key component of the parasympathetic nervous system that innervates many vital organs.

Mydriasis

Dilation of the pupils, often seen as a side effect of anticholinergics.

Tranquilizers

Drugs that calm patients, often used in pre-anesthetic protocols.

Sedatives

Drugs that induce sedation, with effects overlapping those of tranquilizers.

Phenothiazines

A class of tranquilizers used for sedation and anxiety reduction.

Benzodiazepines

A class of sedatives that can also be used to stop seizures.

Alpha-2 Agonists

A class of sedatives that provide sedation and analgesia.
