Neuroanaesthesia and Neuroradiology
Intracranial and spinal pathology, cerebral physiology, neuro-monitoring, neuroradiology and postoperative neuro critical care.
How to prepare for the current Final FRCA Written
Protect breadth for the 90 SBA paper, then rehearse concise CRQ answers that follow the command, mark allocation and printed answer lines.
Core concepts
Concept 1
Neuroanaesthetic decisions balance cerebral perfusion, intracranial volume, oxygen delivery, surgical access and the need for timely neurological assessment.
Exam cue: State the neurological pathology and the physiological insult most likely to worsen it.
Concept 2
Position, airway access, remote-site constraints, contrast, radiation and emergency conversion make neuroradiology a systems problem as well as an anaesthetic one.
Exam cue: Link ventilation, arterial pressure, anaesthetic technique and positioning to cerebral perfusion and intracranial dynamics.
Risk pitfalls and guardrails
Using one intracranial-pressure intervention without addressing its indication, duration and systemic consequences.
Guardrail: Answer the exact lead-in or command instead of reproducing a generic essay.
Ignoring venous drainage, head position or access limitations during a remote procedure.
Guardrail: Answer the exact lead-in or command instead of reproducing a generic essay.
Memory anchors
What determines cerebral perfusion pressure conceptually?
The pressure driving cerebral blood flow depends on arterial inflow pressure relative to the opposing intracranial or venous pressure.
What are core neuroprotection priorities?
Avoid hypoxaemia, severe hypotension, harmful carbon-dioxide extremes, fever, glucose extremes and preventable delays.
Why does positioning matter in neurosurgery?
It affects venous drainage, pressure injury, access, embolic risk, ventilation and the safety of lines and the airway.
What should a wake-up plan answer?
When examination is needed, whether extubation is safe, which residual effects must be excluded and where neurological monitoring continues.
What extra issue defines neuroradiology planning?
Remote access demands reliable monitoring, long lines, communication, immobility and a rehearsed emergency exit or conversion plan.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.

Check-up Questions
A patient with traumatic brain injury has mean arterial pressure 80 mmHg and intracranial pressure 25 mmHg. What is the cerebral perfusion pressure?
During craniotomy, end-tidal carbon dioxide is acutely reduced to treat severe intracranial hypertension. Why should profound hyperventilation be brief?
