Stanford Anesthesia Cognitive Aid Program

Containing 26 crises, this tool was developed by the Stanford Anesthesia Cognitive Aid Program. Development and revisions incorporate iterative simulation testing over multiple decades, research from clinical crises (See 2020 Anesthesia and Analgesia “Clinical uses and impacts of emergency manuals during perioperative crises,” literature content updates, and NASA AMES design expertise. Latest update is V4, 2021. To download this manual for printing or as an interactive PDF, free of cost click here.

Ariadne Labs

These checklists were developed by the team at Ariadne Labs with the goal of improving care during 17 of the most common operating room crises. The checklists were updated in October 2023 to include a new digital and mobile-friendly version of the checklists and also includes new tools to edit checklist content to meet varying local needs. The checklists were tested in a randomized control simulator trial and the results have been published in the New England Journal of Medicine Article, “A Simulation-Based Trial of Surgical Crisis Checklists”.

ADSA – The Ten Minutes Saves A Life! Manual and Application

This manual and electronic application is the first cognitive aid resource for all dental practitioners and was funded through a grant from the Anesthesia Research Foundation of the American Dental Society of Anesthesiology (ADSA).

The Ten Minutes Saves A Life! Manual and Application is divided into sections containing common critical events seen during medical emergencies in the dental office. The algorithms vary with the training level of the provider and are meant to guide management of the crisis during the first 10 minutes until emergency medical services arrives. Drug doses are taken from multiple sources including drug package inserts and authoritative texts. They are automatically populated into the algorithms once the weight of the patient is entered.  There is also a sophisticated local anesthesia calculator to ensure safety with all anesthetics.  To access these tools, please click here.
