title: Heparin need of the patients with cyanotic congenital heart disease during cardiopulmonary bypass. Comparison of cyanotic, acyanotic, rheumatic and atherosclerotic subjects.
abstract: Four groups of patients were studied. Group I: Congenital cyanotic heart disease (CCHD), consisting of 24 subjects aged 5 to 28 (1.4); 18 males and 4 females. Group II: Acyanotic congenital heart disease (ACHD), consisting of 34 patients aged 5 to 42 (20.1); 17 males and 17 females. Group III: Rheumatic heart disease (RHD), consisting of 30 patients aged 11-54 (42.4); 9 males and 21 females. Group IV: Atherosclerotic heart disease (AHD), consisting of 35 patients aged 36 to 65 (49.2); 33 males and 2 females. The haematocrit value (Hct) was the highest in the CCHD group. Total amount of heparin (mg/kg) used during cardiopulmonary bypass was 5.4 in CCHD, 4.66 in ACHD, 4.8 in RHD and 4.6 in AHD group. Mean protamine values was 4.02; 4; 4.03; and 4 respectively. Although the difference of Hct value was statistically different between CCHD and RHD group (p less than 0.001), heparin need was not (p less than 0.1). One-way analysis of variance (F test) showed no difference for heparin need between the four groups (F3.119 = 0.64). Prothrombin time (PT) and activated partial thromboplastin time (aPTT) showed a positive correlation (r = 0.36 and r = 0.25) with heparin need in CCHD group but no correlation was found in RHD group.
