Understanding the New 2025 DAS Intubation Guidelines: What They Mean for Airway Training

The Difficult Airway Society (DAS) has published its 2025 Guidelines for the Management of Unanticipated Difficult Tracheal Intubation in Adults, marking one of the most significant updates to airway management practice in the last decade. The new recommendations place a strong focus on first-attempt success, continuous oxygenation, human factors, and structured team-based training.

For clinical educators and simulation centres, these guidelines reinforce the critical role of high-quality, realistic training. At TruCorp, we welcome the clarity these updates bring and remain committed to supporting clinicians with the tools they need to train safely and effectively.

This article provides a high-level overview. For full details, refer to the official DAS 2025 guidelines published in the British Journal of Anaesthesia here.

What’s New in the 2025 DAS Guidelines?

First-Attempt Intubation as the Priority

The safest airway is one secured on the first attempt. The new guidelines emphasise:

– Optimised patient positioning
– Adequate neuromuscular blockade
– Skilled use of video laryngoscopy
– Continuous oxygen delivery throughout intubation

This shift highlights the importance of repeated practice using realistic airway trainers. .

A Clearer A–B–C–D Algorithm

The updated algorithm simplifies the escalation pathway:

A – Tracheal intubation (maximum 3 + 1 attempts) using a video laryngoscope
B – Second-generation supraglottic airway (up to 3 attempts)
C – Two-person mask ventilation with adjuncts and optimal positioning
D – Declare CICO → front-of-neck access using the scalpel–bougie–tube technique .

The updated algorithm simplifies the escalation pathway

The guidelines highlight the importance of:

– Situational awareness
– Clear role assignment
– Declaring failure early
– Briefings, debriefings, and checklists

Consistent team-based simulation is recommended to support this.

Training and Skills Maintenance

DAS reinforces that clinicians must practise all steps of the algorithm—including CICO—on a regular basis. Simulation is a key component of maintaining competence.

How TruCorp Products Support DAS 2025-Aligned Training:

TruCorp’s range of airway trainers is designed to support every stage of the updated DAS algorithm. All adult airway models are compatible with video laryngoscopes, 
supraglottic airway devices, and standard adjuncts, allowing clinicians to train realistically from first-attempt intubation through to emergency front-of-neck access.

A – First-Attempt Intubation (Video laryngoscopy)
All TruCorp airway models support:
Video laryngoscope and direct laryngoscope use
Tube depth training
Minimising dental pressure
Repeated intubation without degradation
This includes the Smart Airway Adult, AirSim Advance X, AirSim Combo X, and paediatric variants.

B – Supraglottic Airway Device Placement
Every TruCorp model accommodates:
First- and second-generation SGA insertion
Multiple repeated placements
Teaching rescue oxygenation pathways
The AirSim range provides realistic internal anatomy to support correct device positioning and sealing.

C – Two-Person Mask Ventilation
All TruCorp models with skin-based faces—such as AirSim Advance X, AirSim Combo X, and Smart Airway Adult—are suitable for:
Mask seal practice
Airway adjunct insertion (OPA/NPA)
Optimised head positioning
Team-based mask ventilation

D – CICO: Front-of-Neck Access
For CICO training, the AirSim Combo X and dedicated cricothyrotomy trainers (including the upcoming  Smart TruMan Trauma Adult & TruALS with integrated surgical airway capability) offer realistic:
– Cricothyroid membrane identification
– Layered tissue feel
– Scalpel–bougie–tube technique
– Needle and surgical approaches

This supports safe training in the final step of the DAS pathway.

Preparing Training Centres for DAS 2025

The new guidelines underline the value of structured, scenario-based training. TruCorp supports educators and departments in:

Building DAS-aligned training pathways

Developing reproducible skill stations for A, B, C, and D steps

Supporting multidisciplinary team training

Integrating objective performance feedback through  Smart Airway technology

Designing courses focused on first-attempt success

Effective airway management begins with effective training, and TruCorp is committed to equipping clinicians with the tools they need to train with confidence.
