A comparison of noninvasive methods for early detection of hemorrhage: Inferior vena cava ultrasonography and spectrophotometric hemoglobin levels

Objectives Blood hemoglobin concentration measurements using a spectrophotometric method (SpHb), and inferior vena cava ultrasonography (IVC‐US) are noninvasive methods used to follow‐up hemorrhages. We compared their efficacy using voluntary blood donation as a model of moderate (approx. 500 mL) bl...

Description
Summary:Objectives Blood hemoglobin concentration measurements using a spectrophotometric method (SpHb), and inferior vena cava ultrasonography (IVC‐US) are noninvasive methods used to follow‐up hemorrhages. We compared their efficacy using voluntary blood donation as a model of moderate (approx. 500 mL) blood loss. Methods In this prospective observational study enrolling blood‐donor volunteers (BD) and matched controls, we recorded SpHb, IVC diameters, and vital signs. Changes in variables from baseline were compared between BD and controls using the paired t test and Wilcoxon signed rank test. Results We included 118 subjects in the BD group and 95 healthy subjects in the control group. Changes in IVC maximum diameter, IVC minimum diameter, pulse rate, mean arterial pressure, pulse pressure, and shock index, but not in other variables, were significantly different in the BD and the control group (P
