1 Transfusion Increases the Risk for Vasoplegia After Cardiac Operations
Andrej Alfirevic, MD, Meng Xu, MS, Douglas Johnston, MD, Priscilla Figueroa, MD, Colleen G. Koch, MD  The Annals of Thoracic Surgery  Volume 92, Issue 3, Pages (September 2011) DOI: /j.athoracsur Copyright © 2011 The Society of Thoracic Surgeons Terms and Conditions

2 Fig 1 Variables significantly related to odds for developing mild vasoplegia. (ACE = angiotensin-converting enzyme; Afib = atrial fibrillation; CI = confidence interval; CPB = cardiopulmonary bypass; FFP = fresh-frozen plasma; HCT = hematocrit (%); LVF* = left ventricular function—normal-mild vs moderate-severe; OR = odds ratio).

3 Fig 2 (A) Probability in unadjusted odds ratios (OR) of developing mild vasoplegia by number of red blood cells (RBC) transfused. (B) Risk-adjusted probability in odds ratios (OR) of developing mild vasoplegia by number of red blood cell (RBC) units transfused in an intermediate risk patient as calculated for a 70-year-old man with diabetes, history of atrial fibrillation and myocardial infarction, no hypertension, no endocarditis, moderate-severe left ventricular function on preoperative angiotensin-converting enzyme inhibitors, no calcium channel blockers, creatinine (1.4 mg/dL), cardiopulmonary bypass duration of 90 minutes, hematocrit of 30, who receives a transfusion of fresh frozen plasma and platelets.

4 Fig 3 Perioperative variables significantly related to the odds of developing profound vasoplegia. (Afib = atrial fibrillation; CI = confidence interval; CPB = cardiopulmonary bypass; FFP = fresh frozen plasma; HCT = hematocrit (%); LVF* = left ventricular function—normal-mild vs moderate-severe; OR = odds ratio; RBC = red blood cells.)

5 Fig 4 (A) Probability in unadjusted odds ratios (OR) of developing profound vasoplegia by number of red blood cell (RBC) units transfused. (B) Risk-adjusted probability in odds ratios (OR) of developing profound vasoplegia by number of red blood cell (RBC) units transfused in an intermediate risk patient.
