Hemodynamic Changes in Blood Donors

[摘要] Introduction: Everyday, millions of people around the world go through phlebotomy, either to donate blood or for therapeutic intention. The most important worrisome adverse effects are hemodynamic alterations. In this study, hemodynamic changes following blood donation were assessed.Methods & Materials: Three hundred laborers who donated blood voluntarily were enrolled in this study. Blood pressure (BP) and pulse rate were measured before the procedure, ten minutes afterwards, and one week following phlebotomy. Hemoglobin (Hgb) and hematocrit (Hct) were also determined prior to and one week after phlebotomy. Finally, results before and after donation were compared with each other.Results: 242 volunteers had normal BP and 58 were hypertensive. The mean systolic blood pressures (SBP) before phlebotomy, ten minutes after the procedure, and one week later were 120, 117, and 122 mmHg, respectively. During the same periods of time, the mean of diastolic blood pressures (DBP) were 77 , 78 and 78 mmHg , in order , while pulse rates on average were 80 , 82 and 76 beats/minute . None of the aforementioned changes were clinically significant. After one week, Hgb decreased by about 0.3 g/dl (P
