Define type of trauma early – blunt vs penetrating (neck divided into 3 zones), and assess for:
-Distorted anatomy
-Bleeding
-Subcut. Emphysema – injury to gas containing structure
-Other traumatic injury – e.g. head, thorax, abdomen, etc

The difficult paediatric airway = #SCARY. Upper airway obstruction in children – broad range of presentations, three important diagnoses; Croup, Epiglottitis and Inhaled Foreign Body. Here’s some #OnePagers.
#JanuAIRWAY 3/10
#JanuAIRWAY 3/10
#JanuAIRWAY Day 22. Airway Obstruction – Infraglottic (intrathoracic). Again, presents its own set of challenges. Let’s dive in … Here's a #OnePager (Ft. expert contribution Sadie Khwaja @ENT_UK )
#JanuAIRWAY 1/7
#JanuAIRWAY 1/7
Issues:
- Upper/Mid lesions usually low risk – ETT may pass beyond
- Low tracheal/Bronchial lesions = high risk, best managed in specialist centres
- CT scan = essential
- Sudden obstruction can occur at ANY time
- Potential compression of heart/vessels

- Potential compression of heart/vessels
#JanuAIRWAY 2/7
Severe Obstruction:
- Check position patient breaths best in
- Spont vent may help, IPPV may cause airway collapse
- Opinion re: IV vs inhalational = mixed
- Ketamine ?preserves chest wall tone
- Need back up plan
- Consider Heliox/bypass/ECMO before starting

#JanuAIRWAY 1/6
#JanuAIRWAY 1/6
Physiology
- Theory=fixed lesion unaffected by respiratory cycle / anaesthesia induction (most have dynamic element)
- Extrathoracic lesions usually better in expiration +ve pressure splints airway open
- Lets’ revisit flow-volume loops as they can be helpful

- Extrathoracic lesions usually better in expiration +ve pressure splints airway open
- Lets’ revisit flow-volume loops as they can be helpful
#JanuAIRWAY 2/6
Issues:
- Laryngoscopy likely to be uneffected. However, major concern = inability to pass ETT atraumatically beyond the level of obstruction
- Nasendoscopy can be useful to view lesion
- AFOI/FOI may cause ‘cork in bottle’ effect depending on lesion size/location

#JanuAIRWAY Day 20. Airway Obstruction – Periglottic. Often the most challenging for the general anaesthetist. Let’s dive in … Here's a #OnePager
#JanuAIRWAY 1/6
#JanuAIRWAY 1/6
Issues:
- Must d/w with ENT colleagues
- Preop nasendoscopy by experienced nasendoscopist = essential
- AFOI may worsen obstruction – cork in bottle
- Inhalational induction may be difficult
Key Q's
- Static or dynamic obstruction?
- Will ETT pass?

Key Q's
- Static or dynamic obstruction?
- Will ETT pass?
#JanuAIRWAY 2/6
Options:
- May be able to pass ETT – consider MLT or jet vent.
- Apnoeic (HFNO) or intermittent oxygenation technique depending on type of surgery (elective/emergent)
- Awake Tracheal Intubation
- Transtracheal catheter (+/- jet ventilation)
- Awake tracheostomy

Planning in airway obstruction = Key. NASENDOSCOPY can save lives here! ASSESSMENT informs STRATEGY. Let’s revisit some #OnePagers on key questions and airway planning. Remember the decision-making process is multifactorial (maintain situational awareness).
#JanuAIRWAY 3/7
#JanuAIRWAY 3/7
#JanuAIRWAY Day 18. Extra CICO Equipment. At least 2 pieces of equipment deserve extra attention – Rapid-O2 & the Melker airway (key components of the cannula technique one for initial oxygenation & one for securing the airway)! Here’s a pair of #OnePagers to get started.. 1/5
A bonus #OnePager on the QuickTrach airway – used for wide bore cricothyroidotomy, it may still lurk in a few departments throughout the land! Here’s a video as well #FOAMed
#JanuAIRWAY 2/5
#JanuAIRWAY 2/5
Double bonus #OnePager – on the Ventrain Device – a newer, but interesting, device! Can be used both electively & as part of CICO. Here’s a recent paper that highlights its potential read.qxmd.com/read/33432628/… #FOAMed
#JanuAIRWAY 3/5
#JanuAIRWAY 3/5
#JanuAIRWAY Day 17. CICO - Scalpel Techniques. Absolutely ESSENTIAL knowledge for anyone involved in airway management! Here’s a #OnePager with the @dasairway algorithm. Let’s dive in… #FOAMed
#JanuAIRWAY 1/6
#JanuAIRWAY 1/6
DAS advocates scalpel-bougie-tube technique for palpable anatomy and scalpel-finger-bougie-tube technique for impalpable anatomy. Here are some #OnePagers #FOAMed
#JanuAIRWAY 2/6
#JanuAIRWAY 2/6
Perhaps the most difficult part of the process is making the mental leap to pick up the scalpel. That's why mental models and thinking tools like the @VortexApproach are so useful. Check out @NicholasChrimes & Peter Fritz's work

#JanuAIRWAY 3/6
#JanuAIRWAY Day 16 (we’re over ½ way!) Cannot Intubate Cannot Oxygenate (CICO) Scenario - Needle Techniques. Potentially controversial (DAS primarily advocates scalpel techniques), but worth knowing about - particularly for paeds! Here’s some #OnePagers to start..
#JanuAIRWAY 1/7
#JanuAIRWAY 1/7
CICO Key = decide on your plan before you're in the situation. @dasairway promotes scalpel techniques (final common pathway of CICO) MUST be taught. For more on the Needle technique check of Dr Andy Heard’s work at the Perth ‘wet’ lab. 🔗bjanaesthesia.org.uk/article/S0007-…
#JanuAIRWAY 2/7
#JanuAIRWAY 2/7
Integrating the needle technique into CICO algorithms could look something like this #OnePager. There are 2 scenarios for each technique (needle & scalpel):
-palpable and
-impalpable anatomy
another reason to decide early –> lower cognitive load. #FOAMed

#JanuAIRWAY Day 15. Tracheostomies – more than just an ETT through the neck. Here’s a #OnePager covering some of the different tube types. Let’s dive in…
#JanuAIRWAY 1/9
#JanuAIRWAY 1/9
Tracheostomies have potentially been performed since ancient Egypt. The first non-emergency trache was thought to be performed by Asclepiades. He was also a proponent of music therapy (might be of interest to Veena).
#JanuAIRWAY 2/9
#JanuAIRWAY 2/9
There are 4 basic indications for tracheostomy:
1. Provide patent airway
2. Protect the airway
3. Clear secretions
4. Aid weaning from ventilator – the timing of which was investigated in the Tracman study in 2013 (jama.jamanetwork.com/article.aspx?a…)

#JanuAIRWAY 1/9
#JanuAIRWAY 1/9
Several indications for OLV, commonest are thoracic surgery & some oesophagectomies. Essentially three ways to achieve OLV - use of:
- Double lumen tube
- Bronchial Blocker
- Elective endobronchial intubation
Here are some #OnePagers covering the basics
#JanuAIRWAY 2/9

- Bronchial Blocker
- Elective endobronchial intubation
Here are some #OnePagers covering the basics
#JanuAIRWAY 2/9
The key physiological change is the creation of a large shunt – deoxygenated blood (which would normally be oxygenated), returns to the left heart resulting in hypoxaemia.
#JanuAIRWAY 3/9
#JanuAIRWAY 3/9
#JanuAIRWAY Day 13. Jet Ventilation – this is a bit more niche in anaesthesia / airway management, but fascinating. Here’s a #OnePager covering the basics. Let’s dive in…
#JanuAIRWAY 1/8
#JanuAIRWAY 1/8
2 modes of jet ventilation – low frequency (<60 jets/min) & high frequency (>60). Frequency determines device. 2 commonly used devices – Manujet (modified hand operated Sanders injector) or Monsoon (specialised jet ventilator). Here’s a some #OnePagers
#JanuAIRWAY 2/8
#JanuAIRWAY 2/8
Several different potential mechanisms to apnoic oxygenation during HFJV, including:
-Bulk flow
-Laminar flow
-Taylor dispersion
-Pendelluft
-Molecular diffusion
-Cardiogenic mixing

#JanuAIRWAY Day 12. Awake Techniques (ft. expert contributions from @dr_imranahmad). This is a key skill for an airway manager. Here’s a #OnePager covering the basics of Awake Tracheal Intubation (ATI) and nasendoscopy. Let’s dive in…
#JanuAIRWAY 1/11
#JanuAIRWAY 1/11
Key = topicalization (if right, may not need sedation). Top tips:
- Know nerve supply CN V, IX & X.
- Block Ant.ethmoidal AND Sphenopalatine ganglion supply to the nasal septum

#JanuAIRWAY Day 11. The Aintree Intubation Catheter – an amazingly useful piece of equipment – every airway practitioner should be familiar with. Here’s a #OnePager. Let’s dive in…
#JanuAIRWAY 1/5
#JanuAIRWAY 1/5
Main function is as a stop-gap to maintain tracheal access & facilitate tracheal intubation through a supraglottic airway device (SAD) using a fibreoptic scope. They are Long, hollow, semi-rigid, powder blue, polyurethane catheters
#JanuAIRWAY 2/5
#JanuAIRWAY 2/5
To highlight: NEVER insert beyond 26cm. NEVER insufflate with an oxygen flow >2l/min … or just NEVER use for insufflation!
#JanuAIRWAY 3/5
#JanuAIRWAY 3/5
#JanuAIRWAY Day 10. The Cook Airway Exchange Catheter – it’s a useful piece of equipment, but one not everyone will be familiar with. Here’s a #OnePager. Let’s dive in…
#JanuAIRWAY 1/6
#JanuAIRWAY 1/6
Main function is as a stop-gap to maintain tracheal access & facilitate ETT exchange. They are long, hollow, radiopaque, soft-tipped tubes – types for use with single / double lumen tubes.
#JanuAIRWAY 2/6
#JanuAIRWAY 2/6
All users MUST be trained & knowledgeable of how to use such devices together with their limitations and dangers. The Gordon Ewing case makes for tragic reading – but highlights this point. Essential reading for airway practitioners.

#JanuAIRWAY Day 8. Capnography. This is one of essential pieces of monitoring equipment needed during airway management. But its presence isn’t enough, correct interpretation is vital. Let’s start with a #OnePager looking at the different waveforms.
#JanuAIRWAY 1/10
#JanuAIRWAY 1/10
Oesophageal intubation still occurs & EtCO2 = key tool to help prevent avoidable deaths such as Glenda Logsdail’s. Key message = flat or no trace indicates oesophageal intubation until proven otherwise #NoTraceWrongPlace

A fundamental understanding of ‘position’ theory can help e.g. the two-curve theory for videolaryngoscopy. Primary Curve either needs to be flattened or ‘looked around’. Here’s some #OnePagers
#JanuAIRWAY 2/6
#JanuAIRWAY 2/6
2 basic techniques direct (DL) & video (VL), but different scopes require specific techniques. We may even combine multiple scopes (there’s no universally agreed term for this, here we’ve called it Flexi-Assisted Laryngoscopy (FL) Here’s some #OnePagers
#JanuAIRWAY 3/6
#JanuAIRWAY 3/6
#JanuAIRWAY Day 6. Equipment. Good workers know their tools – knowing our equipment is essential! Here’s some #OnePagers - the fundamentals of masks, NP/OPs, SADs, and ETTs.
#JanuAIRWAY 1/4
#JanuAIRWAY 1/4
We’ll cover specific airway devices such as Cook airway exchange catheters, Aintree Intubation Catheters, Staged Extubation Kits, OLV equipment, Tracheostomies, etc later in the month. But in the meantime here's a #OnePager on Frova intubating introducers

#JanuAirway Day 5. Airway Planning. Decision making is the true art of airway management, and something that we don’t really get taught! NAP4 @doctortimcook showed that poor judgement was implicated in many airway complications. Here’s a #OnePager covering the major themes. 1/16
#JanuAirway Why is this an issue? Difficult airways = relatively rare & complications = rarer still. Low exposure --> high anxiety. Add in multiple options @AirwayMxAcademy & Bouwman suggest >1,000,000 combinations of options to oxygenate. More options = more anxiety 2/16

#JanuAIRWAY Day 4. Airway Investigations. 2 broad categories we can use to round out our airway assessment; flow/volume-based lung function tests & imaging techniques. They vary in their usage and usefulness. Here's some #OnePagers #FOAMed on Spirometry and Flow-volume loops 1/17
Spirometry (literally ‘measuring breath’) and flow-volume loops give us information on the mechanics of ventilation. They can be helpful in a more global assessment of respiratory function, but are less helpful in acute airway management.
#JanuAIRWAY #FOAMed 2/17
#JanuAIRWAY #FOAMed 2/17
Diffusing Capacity / Transfer factor can augment lung function tests and give us info about alveolar diffusion and alveolar thickness. Again, helpful in global assessment, but less helpful acutely. Here’s another #OnePager covering the theory and the practice
