Flashcards in AGENTS, CONTROLLING THE FUNCTIONS OF THE CENTRAL NERVOUS SYSTEM - General anesthetics Deck (31):
The state of “general anesthesia” usually includes
- Loss of consciousness, inhibition of sensory and autonomic reflexes
Inhaled anesthetics and intravenous agents having general anesthetic properties
Directly activate GABAA receptors
Indicate the anesthetic, which is an inhibitor of NMDA glutamate receptors:
An ideal anesthetic drug would
- Induces anesthesia smoothly and rapidly and secure rapid recovery
- Posses a wide margin of safety
- Be devoid of adverse effects
Which general anesthetics belongs to inhalants?
Indicate the anesthetic, which is used intravenously
Which inhalants is a gas anesthetic?
Sevoflurane has largely replaced halothane and isoflurane as an inhalation anesthetic of choice because
- Induction of anesthesia is achieved more rapidly and smoothly
- Recovery is more rapid
- It has low post- anesthetic organ toxicity
The limitation of sevoflurane is
Which inhalants lacks sufficient potency to produce surgical anesthesia by itself and therefore is commonly used with another inhaled or intravenous anesthetic?
Which inhaled anesthetics has rapid onset and recovery?
- Nitrous oxide
Indicate the inhaled anesthetic, which reduces arterial pressure and heart rate
Which inhaled anesthetics causes centrally mediated sympathetic activation leading to a rise in blood pressure and heart rate?
Indicated the inhaled anesthetic, which decreases the ventilatory response to hypoxia
Which inhaled anesthetics is an induction agent of choice in patient with airway problems?
Indicate the inhaled anesthetic, which causes the airway irritation
Which inhaled anesthetics increases cerebral blood flow least of all?
Indicate the inhaled anesthetic, which should be avoided in patients with a history of seizure disorders
Which inhaled anesthetics can produce hepatic necrosis?
Indicated the inhaled anesthetic, which may cause nephrotoxicity
Which inhaled anesthetics decreases metheonine synthase activity and causes megaloblastic anemia?
Unlike inhaled anesthetics, intravenous agents such as thiopental, etomidate, and propofol
- Have a faster onset and rate of recovery
- Provide a state of conscious sedation
- Are commonly used for induction of anesthesia
Indicate the intravenous anesthetic, which is an ultra-short-acting barbiturate
Indicate the intravenous anesthetic, which is a benzodiazepine derivative
Which agents is used to accelerate recovery from the sedative actions of intravenous benzodiazepines?
Neuroleptanalgesia has the following properties
- Droperidol and fentanyl are commonly used
- It can be used with nitrous oxide to provide neuroleptanesthesia
- Confusion and mental depression can occur as adverse effects
Neuroleptanalgesia has not the following properties
Hypertension is a common consequence
Which intravenous anesthetics has antiemetic actions?
Indicate the intravenous anesthetic, which causes minimal cardiovascular and respiratory depressant effects
Indicate the intravenous anesthetic, which produces dissociative anesthesia
