Dr. Orser’s Research

Dr. Orser was the inaugural recipient of the Frontiers in Anesthesia Research Award for her project, Anaesthetics, Second Messenger Systems And Ligand-gated Receptors, which led to both important publications and the establishment of the Orser Lab at the University of Toronto. Dr. Orser’s most recent study and publication, Sustained increase in α5GABAA receptor function impairs memory after anesthesia, address why anesthetics can cause long-term memory loss, of vital concern for post-operative patients. This study addresses an observation first reported in 2012 in the Society’s monthly scientific journal, Anesthesia & Analgesia.

Dr. Orser co-founded the Canadian Standards Association Panel on Drug Labeling, the Institute of Safe Medication Practices Canada, and the Patient Safety Committee of the Canadian Anesthesiologists’ Society.
