How to Use These Answers in Exam

Each answer is structured for 20-mark DNB theory format with:

Definitions to anchor the answer
Tables for rapid readability (examiners appreciate structured answers)
Mechanisms and pathophysiology for depth
Clinical management protocols with specific doses/targets
Recent guidelines cited (MHAUS 2020, PROPPR Trial, GAS Trial, FDA 2016, CRASH-2)

Q	Don't Forget
1 – THRIVE	CO₂ still rises (0.15 kPa/min); NOT a substitute for airway
1 – CDH	Surgery NOT emergency; stabilise first; permissive hypercapnia; iNO
2 – Bariatric	Drug dosing basis (TBW vs IBW vs LBW); RSI + video laryngoscopy; CPAP post-extubation
3 – Bronchial Blockers	EZ-blocker, Arndt, Cohen types; slower deflation than DLT
3 – Diastolic dysfunction	E/e' >14; HR 60–80; sinus rhythm mandatory; prefer vasopressors over fluid
4 – Spinal additives	Morphine → delayed 12–24h respiratory depression; dexmedetomidine 3–5 µg
4 – PDPH	Pencil-point needle, finer gauge, parallel bevel = less PDPH; EBP = definitive
5 – Neurotoxicity	GAS Trial = no harm with single <1h exposure; multiple/prolonged = risk
5 – Autonomic	AD occurs ≥T6 lesion; massive HTN; spinal anaesthesia best prevention
6 – Haemorrhagic shock	Lethal triad; TXA within 3h (CRASH-2); 1:1:1 (PROPPR); permissive hypotension
7 – MH	Dantrolene 2.5 mg/kg; ETCO₂ earliest sign; Central Core Disease = strongest association
8 – Supine caval	15° LLT mandatory; phenylephrine > ephedrine for LSCS spinal hypotension
8 – Haematology	Fibrinogen doubles (best PPH severity marker); DVT risk 20× postpartum
9 – Neuromonitoring	MEPs = motor (anterior cord); SSEPs = sensory (posterior cord); TIVA preferred; triggered EMG for pedicle screws
