Hemodynamic studies in sickle cell anemia.
Hemodynamic studies in 13 unselected patients with sickle cell anemia are reported. Twelve of these patients were also studied during mild exercise. The cardiac output at rest was elevated in all and rose significantly with exercise in 9 of the 12 patients. The importance of the increased percentage extraction of oxygen by the tissues in modifying the response of the cardiac output is discussed...
متن کاملHemodynamic responses to oxygen breathing in children with severe anemia.
Hemodynamic responses to 100% oxygen inhalation were examined in seven anemic children (hemoglobin 1.9 to 3.8 g/100 ml blood; hematocrit 9 to 14%). During air breathing mean values for cardiac index were 7.71 L/min/m2, for heart rate 129/min, for stroke index 61.7 ml/m2, and for systemic vascular resistance 11.5 R.U. Oxygen administration significantly decreased mean values of cardiac index to ...
متن کاملSide Effects of Hydroxyurea in Patients with Sickle Cell Anemia
Background: Hemoglobin S arises is the result of a point mutation (A-T) in the sixth codon on the -globin gene on chromosome 11 causing sickle cell anemia. The presence of fetal hemoglobin in infancy plays a relatively protective role for vaso-occlusive symptoms that are the major contributor for the morbidity and mortality among patients with sickle cell anemia. hydroxyurea, an s-phase-specif...
متن کاملBlood Pressure of Children and Adolescents with Sickle Cell Anemia in Basra, Iraq
Background: Blood pressure in patients with sickle cell anemia (SCA) is influenced by autonomic cardiovascular dysfunction, endocrinopathies, nephropathy and nutritional factors. We aimed to evaluate systemic and diastolic blood pressure and its severity among children and adolescents with SCA and determine its association with clinical and hematological variables. Methods: This case-control s...
