Trauma care is a main focus of Dr. Petrosoniak’s teaching and educational efforts. He is the director of trauma education at St. Michael’s Hospital and he is an invited speaker at both national and international conferences on the topics of early trauma resuscitation and massive transfusion protocols among others. He advocates for a re-sequenced approach to trauma resuscitation with an emphasis on physiologic priorities (i.e. address the most life-threatening problem first and resuscitation before intubation) rather than the traditional A-B-C-D-E paradigm. He recently co-edited the trauma issue Damage Control: Advances in Trauma Resuscitation for Emergency Medicine Clinics of North America with his colleague and mentor, Dr. Chris Hicks.
