Table 3 Patient numbers and related percentages by surgical procedure with respect to the whole sample of 3315 patients

From: A simple clinical model for planning transfusion quantities in heart surgery

Surgery procedure Patient number Transfused-patient number Mean value ± SD
of PRBC
CABG 1756 (53.0%) 1092 (62.3%) 2.0 ± 2.7
Valve 1006 (30.3%) 677 (67.3%) 2.6 ± 3.2
Other procedures 553 (16.7%) 439 (79.4%) 3.9 ± 3.5
  1. The number and percentage of transfused patients are also reported for each surgical procedure together with the mean number and standard deviation of PRBC.
  2. PRBC = packs of red blood cells; SD = standard deviation; CABG = coronary artery bypass graft.
