EDAIC Part 1 Paper A: Topics, Format and Study Plan

EDAIC Part 1 Paper A is the basic-science half of the written examination. It tests whether the mechanisms beneath anaesthesiology are available accurately enough for multiple true/false decisions, not merely whether familiar phrases can be recognised.

The current ESAIC Diploma Guide describes Part I as two papers of 60 multiple true/false questions. Each stem has five responses, each independently true or false. The live Part I examination page identifies Paper A as basic science and states that correct responses earn marks without negative marking.

This guide turns that official structure into a practical Paper A plan. It does not assign unofficial percentages to subjects or promise that a particular practice score predicts a pass. ESAIC sets pass marks for the papers through its examination process, and both papers must be passed.

What Paper A is trying to assess

Basic science in EDAIC is not an isolated preclinical memory test. It supports reasoning about drugs, physiology, equipment, monitoring, measurement and evidence. A statement can look simple while changing on one qualifier, unit, condition or direction of effect.

A useful Paper A preparation model has four layers:

1. mechanism: can you explain why the relationship exists?
2. precision: can you distinguish neighbouring definitions, quantities and exceptions?
3. retrieval: can you produce the principle without a chapter heading?
4. MTF judgement: can you apply it independently to five differently worded statements?

Reading may build the first two. Retrieval and question practice are needed for the last two.

The broader Part I syllabus breakdown provides a domain checklist. Keep the official guide and current reading list beside any commercial syllabus map.

A practical Paper A coverage map

ESAIC's public framework labels Paper A broadly as basic science rather than publishing a fixed weighting for every subtopic. For study management, candidates commonly need to organise the material across the following connected areas. Treat this as a working map, not a promise about the number of examination questions.

Anatomy

Study anatomy in functional and procedural context: relationships, spaces, innervation, vascular supply and landmarks that explain anaesthetic practice. Avoid memorising long lists without spatial structure.

Useful retrieval outputs include:

• drawing a labelled pathway from memory;
• describing structures encountered in sequence;
• comparing two regions in a table;
• predicting the consequence of a lesion at a defined point;
• explaining a landmark without looking at an image.

Anatomy becomes durable when diagrams are reconstructed rather than repeatedly viewed.

Physiology and biochemistry

Physiology is a system of relationships. Build causal chains for cardiovascular, respiratory, renal, neurological, endocrine, gastrointestinal, hepatic, temperature and acid–base concepts at the breadth appropriate to the examination.

For each relationship, ask:

• what is controlled;
• what is sensed;
• what changes first;
• what compensates;
• which equation or curve expresses it;
• what assumptions limit the model.

Do not memorise a curve without being able to shift, rotate or reinterpret it. The high-yield physiology guide can orient revision, while a comprehensive source should resolve mechanisms.

Pharmacology

Link pharmacokinetics, pharmacodynamics and drug-class principles. Build comparisons around distribution, clearance, context, receptor effects, interactions, organ dysfunction and adverse-effect mechanisms without reducing learning to brand-name lists.

A productive pharmacology table has columns for mechanism, useful kinetic property, major physiological effect, context that changes the effect and a commonly confused comparator. Test the table from memory in both directions.

The Paper A pharmacology overview provides an initial map. Use the official recommended-reading approach and current authoritative sources where information changes.

Physics, clinical measurement and equipment

These subjects reward understanding more than isolated formula recall. Connect a physical principle to the sensor, display, calibration, limitation and likely source of error. Practise units and proportional reasoning.

For equipment, ask what each component is meant to do, how performance is measured, which assumptions a monitor makes and how a fault changes the observed signal. This is not a catalogue exercise.

Use the physics and clinical measurement guide as a map, then practise explaining devices from input to output.

Statistics and research principles

Be able to interpret rather than merely recite. Organise study around study design, bias, random error, descriptive measures, probability, diagnostic tests, confidence intervals, hypothesis testing and the distinction between statistical and clinical meaning.

For every formula, define the numerator, denominator, population and direction of interpretation. The statistics guide is useful for rebuilding these foundations.
