Alteraciones de la microcirculación en pacientes con anemia drepanocítica según técnicas fotopletismográficas Changes of microcirculation in patients with sickle-cell anemia according to photoplethysmographical techniques

An observational, descriptive and cross-sectional cases series study, of 74 individuals (24 with sickel-cell anemia and 50 apparently healthy with hemoglobinopathies SS) who attended the Special Hematology Department from "Dr. Juan Bruno Zayas Alfonso" Teaching General Hospital in Santiago de Cuba was carried out during the period 20132014, with the aim of identifying the changes of the microcirculation according to variability of the photopletismographical parameters. Studies with the Angiodin PD 3000 were carried out, from the basal register of the pulse volume wave and the reactive hyperemia test. The photoplethysmography in basal state of lower members showed that patients with sickle-cell anemia presented changes in the circulatory system, while, the macroangiopathies had higher frequency in the reactive hyperemia. The obtained results revealed the usefulness of these tests in the detection of circulatory functional disorders. MEDISAN 2015; 19(7):846
