How to Prepare Anaesthesia for NEET PG: Strategy and High-Yield Topics
Anaesthesia yields 4-6 questions in NEET PG. ASA grading, regional blocks, and anaesthetic drug pharmacology are the three pillars -- know the clinical applications, not the chemistry.
Why Anaesthesia matters for NEET PG
Anaesthesia accounts for approximately 4 to 6 questions out of 200 in NEET PG. Despite its small question count, anaesthesia is a highly scoring subject because the content is focused and the question patterns are predictable. The exam tests three areas repeatedly: pre-operative assessment (ASA classification, airway assessment), anaesthetic agents (inhalational and IV anaesthetics, local anaesthetics, muscle relaxants), and regional anaesthesia (spinal, epidural, nerve blocks).
Anaesthesia has substantial overlap with pharmacology (anaesthetic drugs are tested from both perspectives), physiology (respiratory physiology, cardiovascular physiology during anaesthesia), and medicine (perioperative management of medical conditions). A student with strong foundations in these subjects can answer most anaesthesia questions without dedicated anaesthesia study.
The questions tend to be clinically direct: 'an ASA-III patient is scheduled for emergency surgery -- what is the implication?' or 'a patient develops bronchospasm during induction with thiopentone -- what is the likely mechanism?' Students who know the clinical properties and complications of 10-12 anaesthetic drugs can reliably score 3-5 out of 4-6 questions.
Subject weight and question distribution
Expect 4 to 6 questions per paper, constituting 2-3% of the total. Anaesthetic pharmacology (general anaesthetics, local anaesthetics, muscle relaxants) accounts for roughly 35-40% of anaesthesia questions. Regional anaesthesia techniques (spinal, epidural) contribute 25-30%. Pre-operative assessment and monitoring contribute 15-20%. Airway management, pain management, and ICU concepts fill the remainder.
The trend is toward more clinical scenario-based questions and more integration with other surgical specialties. Questions about perioperative management of medical comorbidities (diabetes, hypertension, cardiac disease) during surgery are increasing.
High-yield topics
- **Anaesthetic Pharmacology:** 2-3 questions per paper. Inhalational agents: MAC concept (minimum alveolar concentration -- 1 MAC prevents movement in 50% of patients), sevoflurane (DOC for inhalational induction in children, non-irritant), desflurane (fastest recovery, but irritant -- not for induction), nitrous oxide (diffusion hypoxia, expansion of closed gas spaces -- contraindicated in pneumothorax). IV agents: propofol (smooth induction, causes hypotension, anti-emetic), ketamine (dissociative anaesthesia, only IV anaesthetic that raises BP, bronchodilator -- useful in asthmatics, causes emergence delirium), thiopentone (ultrashort-acting barbiturate, contraindicated in porphyria).
- **Regional Anaesthesia:** 1-2 questions per paper. Spinal anaesthesia (subarachnoid block at L3-L4 or L4-L5, below conus medullaris, hypotension from sympathetic block, total spinal = emergency, complications: post-dural puncture headache -- worse on sitting, better on lying down, treat with epidural blood patch). Epidural: catheter-based, slower onset, can be used for post-operative analgesia. Difference: spinal = faster, denser block, single shot; epidural = slower, titratable, continuous.
- **ASA Physical Status Classification:** 1 question per paper on average. ASA I (healthy), ASA II (mild systemic disease, no functional limitation -- e.g., controlled hypertension), ASA III (severe systemic disease, functional limitation -- e.g., poorly controlled DM), ASA IV (constant threat to life -- e.g., unstable angina), ASA V (not expected to survive without surgery), ASA VI (brain-dead organ donor). Suffix E for emergency.
- **Muscle Relaxants:** 1 question per paper. Succinylcholine (depolarising, rapid onset, short duration, triggers malignant hyperthermia, causes hyperkalaemia -- contraindicated in burns/crush injuries/denervation after 24 hours). Non-depolarising: atracurium (Hofmann elimination -- no renal/hepatic metabolism, safe in renal failure), vecuronium, rocuronium (fastest non-depolarising onset, reversed by sugammadex).
- **Local Anaesthetics:** 1 question per paper. Amide vs ester classification (amides: lidocaine, bupivacaine, ropivacaine; esters: procaine, cocaine, tetracaine -- remember: amides have two 'i's in the name before '-caine'). Bupivacaine: long-acting but most cardiotoxic (direct myocardial depression). Maximum safe dose of lidocaine: 4.5 mg/kg without adrenaline, 7 mg/kg with adrenaline.
- **Airway Management:** 1 question per paper. Mallampati classification (I-IV, based on oropharyngeal structures visible), difficult airway predictors (Mallampati III/IV, short thyromental distance, limited neck extension), and management algorithm (LMA as rescue device, surgical airway as last resort). Cannot-intubate-cannot-ventilate scenario: front-of-neck access (cricothyroidotomy).
- **Malignant Hyperthermia:** 1 question per 2-3 papers. Triggered by succinylcholine and volatile anaesthetics (except nitrous oxide). Features: rapid rise in temperature, muscle rigidity, hypercarbia, tachycardia, elevated CPK. Treatment: immediate dantrolene, active cooling, stop triggering agents. Autosomal dominant inheritance, ryanodine receptor mutation.
Recommended study approach
Aitkenhead's Textbook of Anaesthesia or Ajay Yadav's review book for Indian PG exams are the standard references. For NEET PG, a focused approach works best: study anaesthesia in a single 2-week block covering pharmacology (1 week) and clinical anaesthesia (1 week). Integrate the pharmacology component with your KD Tripathi revision of general anaesthetics and local anaesthetics.
For each anaesthetic agent, learn four things: mechanism, clinical use, key side effect, and contraindication. This four-column approach mirrors how the exam tests agents and keeps your preparation efficient. Do not memorise chemical structures or pharmacokinetic parameters beyond clinically relevant ones.
For regional anaesthesia, understand the anatomy (spinal levels, epidural space), the technique at a conceptual level, and the complications. The exam does not test technique but tests complication recognition and management.
Time allocation
Anaesthesia deserves 2-3 hours per week, totalling roughly 30-40 hours. Most of this should overlap with pharmacology revision. Split 40-60 between reading and MCQ practice.
If short on time, focus on anaesthetic drug pharmacology (covers 2-3 questions) and spinal vs epidural anaesthesia (covers 1-2 questions). These areas can be covered in 15-20 hours and account for 60-70% of anaesthesia questions.
Common mistakes to avoid
- Studying anaesthesia as an entirely separate subject from pharmacology -- anaesthetic agents are tested from both perspectives, and integrated study is more efficient
- Not knowing ASA classification -- it is tested directly and is a 30-second memorisation task that students inexplicably skip
- Confusing spinal and epidural anaesthesia complications -- post-dural puncture headache is specific to spinal (dural puncture), while epidural haematoma is a specific epidural risk
- Ignoring malignant hyperthermia -- it appears every 2-3 papers and the treatment (dantrolene) and triggers (succinylcholine + volatiles) are directly tested
- Studying advanced ICU concepts that are rarely tested in NEET PG -- ventilator management and critical care pharmacology are better covered through medicine
Recommended resources
For NEET PG, Ajay Yadav's review or a concise anaesthesia textbook is sufficient. Aitkenhead's Textbook of Anaesthesia provides depth if needed. Miller's Anesthesia is the international gold standard but is far too detailed for exam preparation.
KD Tripathi's chapters on general anaesthetics, local anaesthetics, and skeletal muscle relaxants provide the pharmacological foundation. Study these alongside your anaesthesia revision for maximum efficiency.
Last-month revision strategy
In the final month, anaesthesia should receive 1 hour every fifth day. Focus on: (1) anaesthetic drug properties table (agent, use, key side effect, contraindication); (2) spinal vs epidural comparison; (3) ASA classification.
Solve 1 PYQ set. Anaesthesia questions are highly predictable, and a well-maintained summary table is sufficient revision. The subject has a high marks-per-hour-of-revision ratio in the last month.
Frequently Asked Questions
How many anaesthesia questions come in NEET PG?
Typically 4 to 6 out of 200. Anaesthetic pharmacology alone covers 2-3 questions, making it the essential preparation area.
Should I study anaesthesia separately?
Study the pharmacology component with KD Tripathi. The clinical component (regional anaesthesia, airway management, ASA classification) requires 1-2 weeks of dedicated study.
How important is ICU for NEET PG?
ICU topics (ventilator modes, shock management, sepsis protocols) appear occasionally but are better covered through medicine than through anaesthesia textbooks. Focus your anaesthesia preparation on perioperative anaesthesia, not critical care.
