NEET PG Anesthasia flashcards — 51 questions with answers

1. Who administered the first successful public demonstration of ether anesthesia, and where and when did it occur?

   William T. G. Morton demonstrated ether anesthesia on October 16, 1846, at Massachusetts General Hospital (the 'Ether Dome'), removing a neck tumor from patient Gilbert Abbott.

2. Which physician introduced chloroform into obstetric anesthesia, and who famously received it during childbirth?

   James Young Simpson introduced chloroform in 1847; John Snow administered it to Queen Victoria during the birth of Prince Leopold in 1853 ('anaesthesia a la reine').

3. Define the three components ('triad') of balanced general anesthesia.

   Hypnosis (unconsciousness/amnesia), analgesia (pain control), and muscle relaxation (akinesia), often with control of autonomic reflexes.

4. What does the ASA Physical Status Classification system grade, and what do ASA I through VI represent?

   It grades a patient's preoperative physical status. ASA I = healthy; II = mild systemic disease; III = severe systemic disease; IV = severe disease that is a constant threat to life; V = moribund, not expected to survive without surgery; VI = brain-dead organ donor. Suffix 'E' = emergency.

5. According to ASA fasting guidelines, what are the minimum fasting times before elective anesthesia for clear liquids, breast milk, and solid/fatty food?

   Clear liquids: 2 hours; breast milk: 4 hours; infant formula/light meal/non-human milk: 6 hours; fatty or fried solid meal: 8 hours.

6. What is the Mallampati classification used for, and what do its four classes describe?

   It predicts difficulty of intubation by oropharyngeal visualization. Class I: soft palate, fauces, uvula, pillars seen; II: soft palate, fauces, uvula; III: soft palate and base of uvula; IV: only hard palate visible. Higher class = higher difficulty.

7. Name the components of the 'LEMON' mnemonic for predicting a difficult airway.

   L = Look externally; E = Evaluate 3-3-2 rule; M = Mallampati; O = Obstruction/Obesity; N = Neck mobility.

8. What is the '3-3-2 rule' for airway assessment?

   3 fingerbreadths between incisors (mouth opening), 3 fingerbreadths from mentum to hyoid bone, and 2 fingerbreadths from hyoid bone to thyroid notch. Failure to meet these predicts difficult intubation.

9. Per ACC/AHA guidelines, what functional capacity threshold (in METs) generally allows a patient to proceed to surgery without further cardiac testing?

   A functional capacity of 4 METs or greater (e.g., climbing two flights of stairs) without symptoms is considered adequate.

10. For how long before elective surgery are clopidogrel and aspirin typically withheld, and what is the general rule for elective surgery after coronary stent placement?

    Clopidogrel ~5-7 days; aspirin often continued or stopped 7 days for high-bleeding-risk procedures. Elective surgery is delayed at least 1 month after bare-metal stents and ideally 6 months (minimum 3-6 months) after drug-eluting stents to allow dual antiplatelet therapy.

11. Define MAC (minimum alveolar concentration) for inhalational anesthetics.

    The alveolar concentration of an inhaled anesthetic at 1 atm that prevents movement in response to a surgical (skin) incision in 50% of patients. It is a measure of anesthetic potency.

12. List the approximate MAC values for nitrous oxide, sevoflurane, isoflurane, and desflurane.

    Nitrous oxide ~104%; desflurane ~6%; sevoflurane ~2%; isoflurane ~1.15%; (halothane ~0.75%). Lower MAC = higher potency.

13. Name four clinical factors that increase MAC and four that decrease MAC.

    Increase MAC: hyperthermia, chronic alcohol use, hypernatremia, infancy (peaks ~6 months), MAOIs/acute amphetamine, red hair. Decrease MAC: increasing age, hypothermia, pregnancy, opioids/sedatives, acute alcohol intoxication, hyponatremia, lithium, hypotension.

14. What is the Meyer-Overton correlation regarding inhalational anesthetics?

    The potency of an inhalational anesthetic correlates directly with its lipid solubility (oil:gas partition coefficient): higher lipid solubility = greater potency = lower MAC.

15. How does the blood:gas partition coefficient affect speed of induction with inhaled anesthetics?

    A lower blood:gas partition coefficient (e.g., desflurane 0.42, nitrous oxide 0.47) means faster onset and recovery; a higher coefficient (e.g., halothane 2.4) means slower induction/emergence.

16. What is the mechanism of action of propofol, and what makes it suitable for short procedures?

    Propofol potentiates GABA-A receptor chloride currents. Its rapid onset, short duration due to rapid redistribution and metabolism, and antiemetic properties make it ideal for induction and short procedures/TIVA.

17. Which IV induction agent best preserves cardiovascular stability, and what adrenal side effect limits its infusion?

    Etomidate provides hemodynamic stability (useful in shock/cardiac disease) but causes adrenocortical suppression by inhibiting 11-beta-hydroxylase, so continuous infusion is avoided.

18. What is the mechanism and key clinical feature of ketamine anesthesia?

    Ketamine is an NMDA receptor antagonist producing 'dissociative anesthesia' with analgesia and amnesia while maintaining airway reflexes and sympathetic tone (raises BP/HR). It causes bronchodilation and emergence hallucinations.

19. What is the mechanism of action of local anesthetics?

    They reversibly block voltage-gated sodium channels on the internal side of the neuronal membrane, preventing depolarization and propagation of the action potential. They bind preferentially to the open/inactivated state (use-dependent block).

20. How are local anesthetics chemically classified, and give an example of each class.

    Esters (metabolized by plasma pseudocholinesterase, e.g., procaine, tetracaine, cocaine, benzocaine) and amides (metabolized by the liver, e.g., lidocaine, bupivacaine, ropivacaine, prilocaine). Amides have two 'i's in the name.
