The design of this manual was inspired by David Borshoff’s “The Anaesthetic Crisis Manual”
Encourage everyone to “speak up” whenever they have concerns using graded assertiveness (e.g. CUS approach)
ABORT |
To terminate an action or procedure “Abort intubation, proceed with LMA insertion” |
ACKNOWLEDGE |
Let me know that you have received & understood message “Administer 1mg IV adrenaline immediately”, “Acknowledge” |
AFFIRM / AFFIRMATIVE |
Convey “yes”, confirmation or “correct” “Is oxygen connected?”, “Affirmative” |
CANCEL |
Annul previous order “Cancel the normal saline bolus” |
CONFIRM |
Request verification for information “Confirm SpO2 is >95%” |
CORRECTION |
An error has been made in the message & the correct version follows “Increase propofol infusion to 20 mL/hr. Correction, increase propofol infusion to 15 mL/hr” |
HOLD SHORT |
Stop before reaching the specified setting “Wean the noradrenaline but hold short of a MAP of 65 mmHg” |
I SAY AGAIN |
Repeat for clarity or emphasis “”I say again: give 1 mg adrenaline IV immediately” |
NEGATIVE |
Convey “No”, “Permission not granted” or “Not correct” “Is oxygen connect?”, “Negative, shall I connect oxygen now?” |
READ BACK |
Repeat all, or the specified part, of my message exactly as received “Read back the adrenaline dose” |
REQUEST |
I would like to know or wish to obtain “Request ABG result” |
RESUME |
Resume a procedure or action that had been paused “Resume tracheal dilation” |
STAND BY |
Wait until other action is completed then I will respond “Do you want normal saline or Hartmann’s?”, “Stand by” |
SAY AGAIN |
Used to request a repeat of the last transmission “Say again all after step 2” |
TIME |
To request time since resuscitation or procedure started “Time?”, “4 minutes since starting CPR” |
UNABLE |
Inability to comply with an instruction or request “Please insert an arterial line”, “Arterial line unable” |
Critical hypoxia is SpO2 <85% & requires emergency buzzer activation (unless modified SpO2 targets are documented by medical staff)
If critical hypoxia is not present, but the fraction of inspired oxygen (FiO2) to achieve target SpO2 range is increasing, bedside staff should notify ICU medical staff if:
Usual SpO2 targets are 92-96% for most patients & 88-92% in COPD patients who are CO2 retainers.
Consider common & lethal causes of hypoxaemia including:
|
|
If unsure of pulse oximetry accuracy, treat hypoxaemia & confirm with an arterial blood gas
Consider shunt if hypoxaemia dose not respond to increased FiO2

Consider common & lethal causes of hypoxaemia including:

|
Patient Factors
|
Staff Factors
|
Many patients (>50%) do not require reintubation if oxygenation & ventilation remain adequate
If stridor present or upper airway swelling suspected, a smaller ETT than previously used may be required
DOPES – Will help to diagnose the problem
If BVM circuit ventilation is easy & patient improves:
If BVM circuit ventilation is easy & patient does not improve:
If BVM circuit ventilation is difficult & patient does not improve:
If a suction catheter cannot be passed the tracheostomy may be either blocked or dislodged.
Do not attempt to bag a potentially dislodged tracheostomy – This may result in rapid evolution of subcutaneous emphysema, leading to distortion of upper airway anatomy and potentially impairing ventilation.
If tracheostomy position is in doubt and patient can be oxygenated from above – a fiberoptic scope may be useful for confirming tube position & assessing obstruction
Reinsertion of a tracheostomy <7 days old is likely to be difficult and carries a high rate of complication – It is a relative contraindication if other options exist
Early – Common, usually benign
|
Late – Uncommon, potentially life-threatening
|
Innominate artery usually crosses the trachea at the 9th cartilage ring
Critical hypotension is SBP <80 mmHg or MAP < 55 mmHg & requires emergency buzzer activation (unless modified SBP targets are documented by medical staff)
If critical hypotension is not present, but the dose of vasoactive drug to achieve target MAP is increasing, bedside staff should notify ICU medical staff if:
Usual MAP target is >65 mmHg for most patients, it may be altered in those with chronic hypertension or hypotension.
If unsure of arterial line accuracy, treat hypotension & confirm with a non-invasive blood pressure.
Check ABCD-Equipment
Underlying causes - is hypotension PROVED?

Response |
Send for helpCode Blue (88) / emergency buzzer |
AirwayApply oxygen mask and open patient's airway Avoid oropharyngeal airways and bag-valve-mask |
BreathingBreathing assessed by looking (do NOT listen or feel) |
CPRCompressions only |
DefibrillateDefibrillate at a distance (from foot of bed) Stop oxygen flow but leave mask on patient Re-start oxygen flow when compressions start |
Early Intubation*Perform only after airborne precautions Use video laryngoscopy (if available) Early discussion of goals |
*A supraglottic airway device (SAD) is an acceptable alternative to intubation if:
|
Parameters | Values to aim for |
Temperature | > 35 °C |
Acid-base status | pH >7.2, Base Excess <-6, Lactate <4 mmol/L |
Ionised calcium | > 1.1 mmol/L |
Haemoglobin | Should not be used alone as a transfusion trigger |
Platelet | ≥50 × 109/L (> 100 × 109/L in TBI) |
APTT | ≤1.5 × normal |
Fibrinogen | ≥1.0 g/L |
Delay CPR for up to 1 minute for above troubleshooting
Attempt verbal de-escalation techniques, including involving trusted others prior to chemical sedation
