The anaesthetic room workflow

Purpose of the anaesthetic room (AR)

  • A controlled area to prepare the patient, equipment, drugs, and team before entering theatre.
  • Aim: safe induction, stable transfer to theatre, and clear communication with the operating team.
  • Not all sites use an AR (some do “in-room” anaesthesia); the same principles apply.

Before the patient arrives: set up your workspace

  • Check the anaesthetic machine and breathing system are working (including oxygen supply, ventilator, scavenging, suction).
  • Prepare monitoring: ECG, non-invasive BP, pulse oximeter, capnography ready for use once airway is managed; temperature probe available.
  • Prepare airway equipment: mask, oral/nasal airways, laryngoscope/video laryngoscope as appropriate, tracheal tubes (sizes), supraglottic airway, bougie/stylet, tape/ties, lubricating jelly.
  • Have a difficult airway plan available: know where the difficult airway trolley is; check availability of second-generation supraglottic airway and front-of-neck access kit per local policy.
  • Prepare IV equipment: cannulas, flushes, giving set, pressure bag if needed, tourniquet, dressings, sharps bin.
  • Prepare drugs with clear labels: induction agent, opioid, muscle relaxant (if planned), vasopressor (e.g., metaraminol/phenylephrine per local practice), antiemetic, local anaesthetic if needed.
  • Check emergency drugs and equipment are immediately accessible: oxygen, suction, bag-valve-mask, anaphylaxis box, defibrillator location.
  • Confirm theatre readiness: operating list, planned procedure/side, patient position, antibiotic plan, special equipment (e.g., tourniquet, cell salvage).

Team brief and roles

  • Introduce yourself to the patient and team; confirm who is the supervising anaesthetist and who is doing what.
  • Agree the plan: airway approach, analgesia plan, muscle relaxation plan, and anticipated problems (aspiration risk, difficult airway, haemodynamic instability).
  • Clarify when the surgeon wants antibiotics, tourniquet inflation time, and any special requirements (e.g., nerve block before/after induction).
  • Make sure help is available: know how to call for senior support and where the emergency buzzer/phone is.

Patient arrival: identity, consent, and baseline safety checks

  • Confirm identity using 3 points (name, DOB, hospital/NHS number) and check wristband matches notes.
  • Confirm procedure and side/site; check allergies and reaction type; check fasting status and last intake.
  • Check key comorbidities and airway history: reflux, OSA, previous difficult intubation, loose teeth, neck mobility.
  • Confirm consent is completed for the surgery; for anaesthesia, ensure the patient understands the plan and has had opportunity to ask questions (local process varies).
  • Check VTE prophylaxis plan and whether pregnancy test is required/available when relevant.
  • Baseline observations and weight (for drug dosing) where possible.

Monitoring and IV access (the basics)

  • Apply standard monitoring early: pulse oximeter first if concerned; then ECG and BP cuff.
  • Measure BP before induction if possible; set cycling interval (often 3–5 min, more frequent during induction).
  • Secure IV access: confirm patency by easy flush and free flow; connect fluids if needed.
  • If IV access is difficult: ask early for help, consider ultrasound, warming, topical local anaesthetic, or using a more experienced cannulator.

Pre-oxygenation and induction (routine adult principles)

  • Pre-oxygenate: tight-fitting mask, high-flow oxygen; aim for good end-tidal oxygen (if available) or at least 3 minutes of tidal breathing.
  • Position: ‘sniffing’ position for most; ramped position for obesity; ensure head and neck supported.
  • Induction: give drugs in a controlled sequence; watch for loss of consciousness, airway obstruction, and hypotension.
  • Ventilation: confirm you can ventilate with mask before giving muscle relaxant unless a rapid sequence induction (RSI) is indicated.
  • After airway device placement: confirm with capnography (continuous waveform), chest movement, and auscultation as appropriate; secure the airway.
  • Set ventilator and alarms appropriately; reassess BP and treat hypotension promptly (fluids/vasopressor as per plan).

Rapid sequence induction (RSI): when and what to remember

  • RSI is used when aspiration risk is high (e.g., not fasted, bowel obstruction, severe reflux, pregnancy, emergency surgery).
  • Key steps: thorough pre-oxygenation, clear plan for failed intubation, appropriate induction agent and fast-acting muscle relaxant per local practice.
  • Cricoid pressure: only if trained staff available and per local policy; release if it impedes ventilation or intubation.
  • Always confirm tracheal tube placement with capnography; be ready to move to a supraglottic airway and follow the failed intubation algorithm if needed.

Transfer to theatre: safe handover and movement

  • Before moving: ensure airway secure, ventilation stable, monitoring attached and visible, IV lines secured, and drugs/infusions safe for transfer.
  • Take oxygen supply with you (portable cylinder if needed) and ensure suction availability.
  • Move carefully: watch for disconnections, kinking of tubing, and pulling of IV lines; assign someone to manage the airway during transfer.
  • On arrival: reconnect to theatre oxygen/ventilator if changing circuits; recheck capnography and vital signs immediately.

Theatre sign-in / WHO checklist: your contribution

  • Participate actively in the WHO ‘Sign In’ and ‘Time Out’ processes; speak up if something does not match (patient/procedure/site/allergy).
  • Confirm antibiotic given (or planned timing), airway plan, aspiration risk, blood availability if relevant, and any critical events anticipated.
  • Document key details: airway device, number of attempts, complications, drugs given, and baseline issues.

Common first-time scenarios and what to do

  • Patient anxious: introduce yourself, explain steps simply, consider a calm environment; discuss sedation only with senior agreement and after safety checks.
  • Hypotension after induction: check depth of anaesthesia, give fluids if appropriate, use vasopressor per local protocol, reassess frequently.
  • Cannot ventilate well with mask: reposition head/neck, use airway adjuncts, two-person technique, increase oxygen flow, consider supraglottic airway early.
  • Difficult cannula: stop repeated traumatic attempts; ask for help early; consider ultrasound and alternative sites.
  • Allergy history unclear: pause, clarify reaction and timing, check records; if uncertain, discuss with senior before giving antibiotics/agents.
What are the minimum monitors for induction?

– Pulse oximetry, ECG, non-invasive BP – Capnography once an airway device is in place (and for any ventilated patient) – Temperature monitoring for longer cases or where clinically indicated

What is pre-oxygenation and why does it matter?

– Breathing high-concentration oxygen before induction – Increases oxygen reserve and buys time if ventilation/intubation is difficult

How do I confirm the tracheal tube is in the trachea?

– Continuous waveform capnography is the key test – Also check chest movement, misting, and auscultation as supportive signs

When should I consider RSI?

– High aspiration risk: not fasted, bowel obstruction, severe reflux, pregnancy, emergency cases – Discuss with your supervisor if unsure

What should I do if I can’t ventilate after induction?

– Call for help early – Reposition, use airway adjuncts, two-person mask technique – Consider supraglottic airway – Follow local failed ventilation/intubation algorithm

What are the key things to check on arrival in theatre after transfer?

– Airway secure and capnography present – Oxygen source connected and adequate – Monitoring reattached and cycling – IV lines patent and not pulled/kinked

What should I label and how?

– Label every prepared syringe immediately after drawing up – Use standard colour-coded labels per local policy – Keep high-risk drugs (e.g., muscle relaxants) separate and clearly identified

What is a ‘failed intubation plan’ at a basic level?

– Plan A: best attempt at intubation with optimal positioning and equipment – Plan B: supraglottic airway to restore oxygenation – Plan C: wake the patient if safe/possible – Plan D: emergency front-of-neck access if cannot oxygenate (senior help urgently)
