Figure 1From: Radiofrequency bipolar hemostatic sealer reduces blood loss, transfusion requirements, and cost for patients undergoing multilevel spinal fusion surgery: a case control studyAverage hemoglobin concentrations compared in the radiofrequency bipolar hemostatic sealer (RBHS) and control groups. Baseline hemoglobin was similar between groups, but the decrease in hemoglobin was less in the RBHS group (P = 0.04), and the hemoglobin at discharge was higher in the RBHS group (P = 0.01).Back to article page
