Anesthesiology Terms
AMBU
artificial manual breathing unit
analgesia
A deadening or absence of the sense of pain without loss of consciousness.
anesthesia
A drug, administered for medical or surgical purposes for total or partial loss of sensation
anesthesia awareness
when a patient under general anesthesia receives insufficient medication or the anesthesia wears off too quickly to prevent consciousness and recall, which can be very traumatic if the patient is undergoing a surgical procedure
anesthesia care team
The group of people that will be taking care of you during your procedure.
anesthesiologist
A medical doctor who is specialized in the practice of anesthesiology
anesthesiologist assistant (AA)
Anesthesiologist Assistants are highly skilled, knowledgeable, master degree earning members of the anesthesia care team who with their impeccable safety records work side by side with Certified Registered Nurse Anesthetist's ( CRNA's).
anesthetist
any person trained to admin anesthesia
buprenorphine
An opioid pain medication. An opioid is sometimes called a narcotic. Buprenorphine transdermal (skin patch) is used to treat moderate to severe chronic pain when treatment is needed around the clock.
butorphanol
An opioid pain medication. An opioid is sometimes called a narcotic. Butorphanol is used to treat moderate to severe pain
catheter
a rubber or flexible plastic tube inserted in the veins or arteries to deliver medications to the body or expel fluids from it
central venous catheter
a catheter placed in a large vein, such as the jugular vein in the neck, to infuse large amounts of medication or fluid
certified registered nurse anesthetist (CRNA)
like an anesthesiologist, a CRNA administers anesthesia and monitors and manages patients before, during and immediately following a medical or surgical procedure
codeine
A group of drugs called narcotic pain medicines. Codeine is used to treat mild to moderately severe pain.
cryoanesthesia
insensibility resulting from cold
diazepam
A group of drugs called benzodiazepines (ben-zoe-dye-AZE-eh-peens). Diazepam affects chemicals in the brain that may become unbalanced and cause anxiety
dissociogenics
Over-stimulates CNS instead of depressing it, dissociating the mind from the body
endotracheal tube
A breathing tube, usually made of flexible plastic, inserted in a patient’s trachea to ensure the airway remains open and protected so air is able to reach the patient’s lungs; used during induction and intubation
epidural anesthesia
a type of regional anesthesia where a small catheter is inserted in the back just inside the spinal canal (the epidural space) to allow infusion of local anesthetic
ether
General name for a class of inhaled anesthetics used in the induction and maintenance of anesthesia
extubation
Removal of an endotracheal tube after patient is recovered
fentanyl
Fentanyl is a narcotic (opioid) pain medicine
general anesthesia
a state of total unconsciousness resulting from anesthetic drugs (as for a major surgical operation)
halothane
an inhaled anesthetic used in the induction and maintenance of anesthesia that is generally well-tolerated
hydromorphone
Hydromorphone is an opioid pain medication. An opioid is sometimes called a narcotic. Hydromorphone is used to treat moderate to severe pain.
induction
production of anesthetic state/unconsciousness by use of appropriate agent
inhalant
A broad range of drugs whose volatile vapors are taken in via the nose and trachea.
intravenous (IV) catheter
a catheter inserted into the vein(s) to give medications and fluids before, during and after surgery or a medical procedure
intubate/intubation
placement of a flexible plastic tube in the trachea to protect and support the airway and allow for mechanical or artificial respiration; usually done when the patient is asleep
isoflurane
A nonflammable liquid administered by vaporizing, is a general inhalation anesthetic drug
ketamine
a dis-associative anesthetic administered intravenously and used in the induction and maintenance of general anesthesia
laryngeal mask airway (LMA)
A tube with an inflatable cuff that is inserted into the pharynx after induction to manage breathing while unconscious.
laryngoscope
A device that permits the anesthesiologist to view the glottis and vocal cords to protect them from possible injury with intubation
-leptic
suffix that means "pertaining to overloading"
lidocaine
A local anesthetic (numbing medication).
local analgesics
acts directly on the nerves to block impulse transmission
local anesthesia
loss of sensation in a small area of the body (as when a local anesthetic is injected for a tooth extraction)
maintenance
phase of anesthesia that starts after induction; animal enters & stays at anesthetic depth adequate enough for surgical procedure
meperidine (Demerol)
An opioid pain medication. An opioid is sometimes called a narcotic. Meperidine is used to treat moderate-to-severe pain.
mixed agonist/antagonist
A mixed agonist-antagonist is a drug or receptor ligand that possesses pharmacological properties similar to both AGONISTS and ANTAGONISTS for certain RECEPTOR sites.
morphine
Morphine is an opioid pain medication. An opioid is sometimes called a narcotic. Morphine is used to treat moderate to severe pain
naloxone
An special narcotic drug that reverses the effects of other narcotic medicines
narcotic agonists
stimulate opioid receptors in body to produce physiological effects
narcotic antagonist
reverse" the effects of opiods
narcotics
opioid derived from plants or synthesized; have analgesic effects on the body
neostigmine
Neostigmine affects chemicals in the body that are involved in the communication between nerve impulses and muscle movement.
nerve block anesthesia
anesthesia of an area supplied by a nerve
neuroleptanalgesics
Combination of narcotics & sedatives/tranqs
has a calming effect over patient as well as pain relief
neuroleptic
Drugs which takes hold of the nervous system.
nitrous oxide
Nitrous oxide is used in surgery and dentistry for its anesthetic and analgesic effects. It is known as "laughing gas" due to the euphoric effects of inhaling it.
oxymorphone
Oxymorphone is an opioid pain medication. An opioid is sometimes called a narcotic. Oxymorphone is used to treat moderate to severe pain.
positive pressure ventilation
artificial means of ventilation
propofol
A drug that reduces anxiety and tension, and promotes relaxation and sleep or loss of consciousness.
recovery
the period between the stoppage of anesthetic administration stops and when the pt can walk/stand w/out assistance
regional anesthesia
loss of sensation in a region of the body produced by application of an anesthetic agent to all the nerves supplying that region
respiration
exchange of O2 & CO2 at cellular/alveolar level
sedation
medication(s) that create a state of calm and reduced pain and/or anxiety
sedative/tranquilizer
agent that calms nervousness, irritability, and excitement
sodium pentothal/sodium thiopental
a rapid-onset, short-acting general anesthetic administered intravenously; most commonly used in the induction phase of anesthesia.
surgical anesthesia
degree of anesthesia at wh/ most surgeries may be safely performed
tidal volume
amount of air passing in/out of lungs in one breath
topical anesthesia
loss of sensation confined to the skin or mucous surfaces
ventilation
movement of air into and out of lungs
yohimbine
Yohimbine increases the amount of blood that is allowed to flow into the penis and prevents blood from flowing out of the penis. It can cause an erection. Yohimbine is used to treat and diagnose some types of impotence.
