Appointments and Affiliations:

Research Foci:

  • Resuscitation and coagulopathy in critically injured patients
  • Quality improvement in trauma care

Research Summary:

The focus of Dr. Nascimento's research is in clinical transfusion medicine, hemostasis and quality of care of bleeding patients during the initial resuscitation phase.

He is a member of Sunnybrook's Code Omega (life-threatening bleeding code) Committee and Transfusion Medicine Committee. He is also a member of the Canadian National Committee for Blood Shortage. In addition, Dr. Nascimento is part of the Sunnybrook's Trauma Research Group, which recently completed its first randomized controlled trial on massively bleeding trauma patients comparing a one red blood cell to one plasma to one platelet (formula-driven) transfusion strategy against a standard laboratory-guided transfusion strategy.

Dr. Nascimento is also co-investigator of the Pragmatic, Randomized, Optimal Platelet and Plasma Ratios (PROPPR) This Phase 3 multicentre, prospective, randomized controlled trial at level one adult trauma centers in North America, compares different ratios of blood products given to trauma patients who are predicted to require massive transfusions (greater than 10 units of packed red blood cells within the first 24 hours).

He is also the recipient of the 2010–2011 AABB National Blood Foundation grant to conduct research on early coagulopathy in trauma.
