Intended Purpose
Anaesthesia Companion brings together anaesthesia-related guidelines, protocols, algorithms, teaching notes, and resources in one place for clinicians and trainees. Use it to review perioperative planning, emergency algorithms, airway management summaries, regional anaesthesia timing references, and more.
What it provides
- Weight- and age-adjusted drug dose reference tables
- Validated clinical scoring tools (APACHE II, SOFA, RCRI, Apfel, etc.)
- Regional anaesthesia & anticoagulation timing guidance (ASRA 5th Ed)
- Emergency algorithm reference (QRH 2023, ALS/Resus Council UK)
- Airway management algorithm summaries (DAS guidelines)
- Labour analgesia protocols (OAA/RCOA)
- Perioperative medication management guidance
- Teaching notes and educational resources for trainees
- ROTEM-guided haemorrhage management pathways
What it is not
- A substitute for clinical judgement or direct patient assessment
- A diagnostic or prescribing tool
- A replacement for current BNF, SPC, or institutional protocols
- A system for storing or processing identifiable patient data
- Suitable for use by non-healthcare professionals without supervision
- Validated for veterinary or non-human medicine
- A definitive source — all content must be confirmed against current standards and your patient's situation
Important: Information in this app is for professional education and reference only. It must always be confirmed against current evidence-based standards and your individual patient's clinical situation before application.

Instructions for Use
Before Use
- Confirm you are a qualified healthcare professional or supervised trainee.
- Ensure you have a stable connection for up-to-date content.
- Verify the app version in the footer matches the current release.
- Do not use this app as your sole reference — always cross-check with BNF, SPC, and local protocols.
During Use
- Enter accurate patient weight, age, and sex before calculating doses.
- Review all outputs critically — no software output overrides clinical judgement.
- For paediatric patients, confirm all doses with a senior clinician.
- Dose ranges reflect standard adult references; adjust for renal, hepatic, and cardiac status.
- Scoring systems provide risk estimates, not diagnoses.
After Use
- Document clinical decisions in the patient record — not in this app.
- Report any discrepancies or errors to the developer promptly.
- Do not share screenshots of patient-specific outputs outside your clinical record system.
- Check for updates by verifying the version shown in the footer.
Warnings & Known Limitations
Warnings
- Not a substitute for clinical judgement. All outputs are advisory. The treating clinician bears full professional responsibility for all clinical decisions.
- Drug dose ranges reflect standard published guidelines. Individual pharmacokinetics, comorbidities, and concurrent medications must always be considered.
- Emergency situations: Always prioritise direct patient assessment and your institution's emergency protocols over app outputs.
- Connectivity: Some features require internet access. Do not rely solely on this app in areas with unreliable connectivity without confirming offline content is current.
- Paediatric use: All paediatric dosing outputs require independent verification by a senior clinician.
- Pregnancy: Drug doses in pregnancy are not always reflected in standard ranges. Consult specialist obstetric anaesthesia references.
Known Limitations
- Framingham Risk Score uses a simplified approximation; validated gender-specific coefficient tables are not fully implemented in this version.
- Infusion rate calculations assume standard concentrations; verify against your pharmacy's prepared concentration.
- ECMO parameters are guidance values only; actual management requires specialist perfusionist and critical care input.
- Drug interactions are not assessed by this app. Always consult the BNF Interactions checker or a clinical pharmacist.
- Content currency: Guidelines are updated periodically. The last content audit was completed May 2026 (v2.1.0).
- AI tools (where present) use large language models and may produce plausible but inaccurate clinical content. All AI outputs require critical clinician review.
