Consenting for an urgent investigation like a lumbar puncture tests your ability to inform a frightened, unwell patient quickly while still respecting their autonomy. Structure keeps you safe.
How to structure it
- Explain why the test is needed and how it will help, conveying any urgency without bullying.
- Describe the procedure simply — positioning, local anaesthetic, what they will feel.
- Give the benefits, common after-effects (such as headache) and rarer serious risks.
- Screen for contraindications and check there is no pressure on the decision.
- Answer questions and confirm informed consent.
Common pitfalls
- Letting urgency tip into coercion.
- Using frightening jargon about the spine.
- Skipping the check of understanding when short of time.
Marks come from balancing time-sensitivity with a genuinely informed, voluntary decision and a reassured patient.
