ABSTRACT

BACKGROUND: A relatively new method of electrocautery, the radiofrequency bipolar hemostatic sealer (RBHS), uses saline-cooled delivery of energy, which seals blood vessels rather than burning them. We assessed the benefits of RBHS as a blood conservation strategy in adult patients undergoing multilevel spinal fusion surgery. METHODS: In a retrospective cohort study, we compared blood utilization in 36 patients undergoing multilevel spinal fusion surgery with RBHS (Aquamantys, Medtronic, Minneapolis, MN, USA) to that of a historical control group (n = 38) matched for variables related to blood loss. Transfusion-related costs were calculated by two methods. RESULTS: Patient characteristics in the two groups were similar. Intraoperatively, blood loss was 55% less in the RBHS group than in the control group (810 ± 530 vs. 1,800 ± 1,600 mL; p = 0.002), and over the entire hospital stay, red cell utilization was 51% less (2.4 ± 3.4 vs. 4.9 ± 4.5 units/patient; p = 0.01) and plasma use was 56% less (1.1 ± 2.4 vs. 2.5 ± 3.4 units/patient; p = 0.03) in the RBHS group. Platelet use was 0.1 ± 0.5 and 0.3 ± 0.6 units/patient in the RBHS and control groups, respectively (p = 0.07). The perioperative decrease in hemoglobin was less in the RBHS group than in the control group (-2.0 ± 2.2 vs. -3.2 ± 2.1 g/dL; p = 0.04), and hemoglobin at discharge was higher in the RBHS group (10.5 ± 1.4 vs. 9.7 ± 0.9 g/dL; p = 0.01). The estimated transfusion-related cost savings were $745/case by acquisition cost and approximately 3- to 5-fold this amount by activity-based cost. CONCLUSIONS: The use of RBHS in patients undergoing multilevel spine fusion surgery can conserve blood, promote higher hemoglobin levels, and reduce transfusion-related costs. More... »

    "description": "BACKGROUND: A relatively new method of electrocautery, the radiofrequency bipolar hemostatic sealer (RBHS), uses saline-cooled delivery of energy, which seals blood vessels rather than burning them. We assessed the benefits of RBHS as a blood conservation strategy in adult patients undergoing multilevel spinal fusion surgery.\nMETHODS: In a retrospective cohort study, we compared blood utilization in 36 patients undergoing multilevel spinal fusion surgery with RBHS (Aquamantys, Medtronic, Minneapolis, MN, USA) to that of a historical control group (n\u2009=\u200938) matched for variables related to blood loss. Transfusion-related costs were calculated by two methods.\nRESULTS: Patient characteristics in the two groups were similar. Intraoperatively, blood loss was 55% less in the RBHS group than in the control group (810\u2009\u00b1\u2009530 vs. 1,800\u2009\u00b1\u20091,600 mL; p\u2009=\u20090.002), and over the entire hospital stay, red cell utilization was 51% less (2.4\u2009\u00b1\u20093.4 vs. 4.9\u2009\u00b1\u20094.5 units/patient; p\u2009=\u20090.01) and plasma use was 56% less (1.1\u2009\u00b1\u20092.4 vs. 2.5\u2009\u00b1\u20093.4 units/patient; p\u2009=\u20090.03) in the RBHS group. Platelet use was 0.1\u2009\u00b1\u20090.5 and 0.3\u2009\u00b1\u20090.6 units/patient in the RBHS and control groups, respectively (p\u2009=\u20090.07). The perioperative decrease in hemoglobin was less in the RBHS group than in the control group (-2.0\u2009\u00b1\u20092.2 vs. -3.2\u2009\u00b1\u20092.1 g/dL; p\u2009=\u20090.04), and hemoglobin at discharge was higher in the RBHS group (10.5\u2009\u00b1\u20091.4 vs. 9.7\u2009\u00b1\u20090.9 g/dL; p\u2009=\u20090.01). The estimated transfusion-related cost savings were $745/case by acquisition cost and approximately 3- to 5-fold this amount by activity-based cost.\nCONCLUSIONS: The use of RBHS in patients undergoing multilevel spine fusion surgery can conserve blood, promote higher hemoglobin levels, and reduce transfusion-related costs.",
