Compared with the placebo group , patients who received desmopressin had less blood loss in 24 h ( mean 624 [ SD 209 ] vs 1028 mL [ 682 ] p = 0.0004 ) and required less transfusion of red blood cells ( 1.1 [ 022 ] vs 2.2 U [ 0.32 ] p = 0.009 ) , platelets ( 0.1 [ 0.04 ] vs 1.9 U [ 4.5 ] p = 0.0001 ) , and fresh-frozen plasma ( 0.1 [ 0.07 ] vs 0.75 U [ 0.21 ] p = 0.0008 ) , and had less total blood-donor exposures ( 1.56 [ 0.31 ] vs 5.2 [ 0.8 ] p = 0.0001 ) .
