Historical ArticleJohn Henry Evans, MD: Founding Chairman of the Board of Governors of the International Anesthesia Research Society, and a Forgotten Pioneer of Oxygen Therapy.
The theoretical and practical foundations of modern oxygen therapy were established during the first half of the 20th century. John Henry Evans, MD, inaugural chairman of the Board of Governors of the International Anesthesia Research Society (IARS), was an early pioneer in this field. ⋯ Additionally, Evans experimented with the subcutaneous injection and intravenous infusion of oxygen, reporting significant benefits of the former in several acute inflammatory conditions, as well as a variety of chronic ailments. While these contributions have largely been forgotten, Evans expanded the remit of anesthesiology beyond the operating theater and the original charter of the IARS and helped lay the foundations for the rational use of oxygen as a therapeutic agent in all areas of medicine.

Randomized Controlled TrialSuccess and Time to Oxygen Delivery for Scalpel-Finger-Cannula and Scalpel-Finger-Bougie Front-of-Neck Access: A Randomized Crossover Study With a Simulated "Can't Intubate, Can't Oxygenate" Scenario in a Manikin Model With Impalpable Neck Anatomy.
Emergency front-of-neck access (FONA) is particularly challenging with impalpable neck anatomy. We compared 2 techniques that are based on a vertical midline neck incision, followed by finger dissection and then either a cannula or scalpel puncture to the cricothyroid membrane. ⋯ In a manikin simulation of impalpable neck anatomy and bleeding, the SFC approach demonstrated superior performance in oxygen delivery and was also the preferred technique of the majority of study participants. Our study findings support the use of a cannula-based FONA technique for achieving oxygenation in a CICO situation, with the prerequisite that appropriate training and equipment are available.
