Research Synopsis

Dr. Wasowicz’s research interest concentrates on two main fields: (1) introducing novel technologies into perioperative medicine and (2) introducing solid phase microextraction (SPME) into clinical medicine.

The first part of Dr. Wasowicz’s activities resulted in rolling out bedside monitoring of coagulation system at Toronto General Hospital. It was based on clinical application of thromboelastography (TEG) and its modification platelet mapping assay. This part of his activity also included introduction of volatile based sedation into intensive care environment. His group conducted several safety studies and two randomized trials investigating use of volatile based sedation for short-term and long-term period within the ICU environment.

SPME is a novel analytical technology, which allows combining biological sample extraction and processing into one step. It can be applied to any biological system (fluid, tissue) and measures concomitantly several substances or metabolites. Dr. Wasowicz’s group initiated multidisciplinary collaboration between Toronto General Hospital, University of Toronto, University of Waterloo and industrial partners, which initiated introduction of this technology into perioperative medicine. The results of first projects showed that doses of tranexamic acid used routinely during cardiac surgical procedures are exceeding desired plasma levels. Also, using SPME technology they have been able to show that rocuronium bromide can be used as a marker of early liver function post liver transplantation.
