LECTURES

A sequence to aid response to anaphylaxis in a time-critical situation

The rationale underpinning this algorithm, along with its related concepts, is presented in a one-hour lecture by Dr. Ben McKenzie.

Dr. McKenzie has over a decade of experience as a Director of Emergency Medicine Training and more than 15 years as a retrieval specialist. He is deeply committed to advancing the standards of Emergency Medicine.

This lecture has been delivered to approximately two-thirds of Victoria’s Emergency Departments and has been viewed by over 500 emergency medicine consultants and registrars. It is available to watch in full or as a series of six 10-minute episodes, providing flexible viewing options to suit individual schedules.

A man in a black blazer and white shirt standing in front of a large screen and pointing with a remote control. The screen displays medical instructions for airway management, including details about ET tube insertion and ventilation. A camera is mounted on the wall below the screen, and a poster with health information is also visible.

The Complete Lecture Series

Duration: 67 minutes

The rationale behind this algorithm and related concepts are presented by Dr Ben McKenzie in an hour-long lecture presentation.

The lecture can be watched as one video, and is also available in six, 10-minute video episodes for more flexible viewing options.

Section 1

Recognising Anaphylaxis

Duration: 13 minutes

In section 1/6, Ben welcomes you to the lecture series and discusses often missed diagnosis of paediatric anaphylaxis, diagnostic criteria, severity grading system: Acute allergy is a continuum of disease from mild skin symptoms to cardiac arrest.

Section 2

Part 1: Treating Anaphylaxis

Duration: 16 minutes

In section 2/6, Ben tells the tragic story of James Tsindos. James was a talented pianist and otherwise healthy teenager who entered a metropolitan hospital emergency department with anaphylaxis/asthma and normal vital signs. James died 8 weeks before Max because of almost identical problems in care. Ben discusses anaphylaxis treatment from basics to critical care specialist management before arrest.

Section 3

Arrest Algorithms

In section 3/6, Ben discusses key anaphylaxis & asthma resuscitation concepts that are a "special circumstance", including parallels with trauma. In this video, Ben explores:

  • The difference betweenb VF vs Hypoxic arrest

  • Why can asthma and anaphylaxis be considered in the same algorithm

  • Recognising respiratory arrest; and

  • Overcoming the problem of decentralised teaching.

Section 4

10 Concepts: The First

Duration: 10 minutes

In section 4/6, Ben covers the "Maximum 4 minutes" until hypoxic ischaemic encephalopathy (the first of 10 concepts informing AMAX4, including the topics: "Why 4 minutes?", Martin and Elaine Bromiley, the impact of time critical care, the "Hard deck, Hard limits and an important - and apt - "Top Gun" analogy.

Section 5

10 Concepts: The Other Nine Concepts

Duration: 11 minutes

In section 5/6, Ben details the other 9 of 10 concepts informing AMAX4. These include:

  • Why muscle relaxant before sedation

  • Why ETT and not LMA or Mask

  • Xtreme Obstructive Ventilation

  • What airway pressures you can expect

  • What cognitive assistance you need; and

  • Understanding the expected course. 

Section 6

Max

Duration: 10 minutes

In section 6/6, Ben talks about what happened to Max and understand the timeline of Max's care with paramedics and then the Emergency Department.
