GENERAL ANESTHETICS Flashcards
STAGES OF ANESTHESIA (GUEDEL’S SIGNS)
ADSM
Stage 1: Analgesia
Stage 2: Disinhibition
Stage 3. Surgical anesthesia
Stage 4: Medullary depression
Measure of concentration of inhaled anesthetics
Partial pressure or “tension”
Best measure of potency of inhaled anesthetics
Minimum Alveolar Anesthetic Concentration
Inhalation anesthetic that has a characteristic PUNGENT ODOR
Desflurane
Inhalation anesthetic that has a characteristic SWEET ODOR
Sevoflurane
Inhalation anesthetic contraindicated in asthmatic patients
Desflurane
Inhalation anesthetic contraindicated in patients with asthma
Desflurane
Inhalation anesthetic preferred in patients with asthma
Sevoflurane
Inhalation anesthetic that presents with CORONARY STEAL SYNDROME
Isoflurane
Inhalation anesthetic with characteristic spike-and-wave activity in EEG
Enflurane
Inhalation anesthetic with the highest propensity to cause HEPATITIS
Halothane
Inhalation anesthetic with the highest potency and lowest MAC
Methoxyflurane
Inhalation anesthetic for minor surgery and dental procedures
Nitric oxide
Inhalation anesthetic with the least potency and lest cardiotoxic effects
Nitrous oxide
Laughing gas (euphoria)
Nitrous oxide
Inhalation anesthetic are undesirable for patients with increased ICP except:
Nitrous oxide
ALL inhaled anesthetics depress normal cardiac contractility > decrease MAP via different mechanisms. Except:
Nitrous oxide
ALL inhaled anesthetics have a BRONCHODILATING properties except:
DESFLURANE
This condition results from mutation of RYANODINE RECEPTOR of the skeletal muscle that results to uncontrolled release of Ca2+ from SR. Occurs when susceptible individual are exposed to volatile anesthetics and succinylcholine
MALIGNANT HYPERTHERMIA
Most reliable test to establish susceptibility to malignant hyperthermia:
Caffeine-Halothane contracture test
Treatment for Malignant hyperthermia:
Dantrolene
IV anesthetic used for identification of epileptic foci
Barbiturates
IV anesthetic that is a potent vasoconstrictor best for patients with increased ICP
Barbiturates
IV anesthetic that causes ACUTE INTERMITTENT PORPHYRIA
Barbiturates
Intraarterial injection of this IV anesthetic can lead to gangrene
Barbiturate
