Article: Early injection of high-dose recombinant factor VIIa decreases blood loss and prolongs time from injury to death in experimental liver injury.
[show abstract] [hide abstract]
ABSTRACT: Recombinant factor VIIa (rFVIIa) is used for treatment of bleeding episodes in hemophilia patients who develop inhibitors to factors VIII and IX. We tested the hypothesis that administration of rFVIIa early after injury would decrease bleeding and prolong the time from injury to death after experimental hepatic trauma. Anesthetized swine were cannulated for blood sampling and hemodynamic monitoring. Avulsion of the left median lobe of the liver induced uncontrolled hemorrhage. After a 10% reduction in mean arterial pressure, animals (n = 8 per group) were blindly randomized to receive intravenous rFVIIa 180 microg/kg, rFVIIa 720 microg/kg, or placebo. Pathologic examination of brain, lung, kidney, heart, and small bowel was performed to assess intravascular thrombosis. RESULTS Mortality during the first hour was 50% (four of eight) in controls versus 0% with rFVIIa 720 microg/kg (p = 0.02, chi2). Blood loss was decreased in the rFVIIa 720 microg/kg group versus the placebo group (13.2 +/- 5.5 mL/kg vs. 21.9 +/- 7.7 mL/kg;p = 0.0223). Time from injury to death was significantly prolonged in the rFVIIa 720 microg/kg group compared with placebo (116 minutes vs. 8.5 +/- 3.5 minutes; p= 0.02). No macro- or microthrombi in vital organs were identified on pathologic examination. Intravenous administration of high-dose rFVIIa early after induction of hemorrhage decreased bleeding and prolonged survival. No evidence of thrombosis in vital organs was observed.The Journal of trauma 01/2003; 53(6):1053-7. · 2.48 Impact Factor -

ABSTRACT: Background : Recombinant factor VIIa (rFVIIa) is used for treatment of bleeding episodes in hemophilia patients who develop inhibitors to factors VIII and IX. We tested the hypothesis that administration of rFVIIa early after injury would decrease bleeding and prolong the time from injury to death after experimental hepatic trauma. Methods : Anesthetized swine were cannulated for blood sampling and hemodynamic monitoring. Avulsion of the left median lobe of the liver induced uncontrolled hemorrhage. After a 10% reduction in mean arterial pressure, animals (n = 8 per group) were blindly randomized to receive intravenous rFVIIa 180 μg/kg, rFVIIa 720 μg/kg, or placebo. Pathologic examination of brain, lung, kidney, heart, and small bowel was performed to assess intravascular thrombosis. Results : Mortality during the first hour was 50% (four of eight) in controls versus 0% with rFVIIa 720 μg/kg (p = 0.02, χ2). Blood loss was decreased in the rFVIIa 720 μg/kg group versus the placebo group (13.2 ± 5.5 mL/kg vs. 21.9 ± 7.7 mL/kg;p = 0.0223).

Article: A prospective, randomized trial of Acticoat versus silver sulfadiazine in the treatment of partial-thickness burns: which method is less painful?
[show abstract] [hide abstract]
ABSTRACT: Despite recent improvements in analgesia, pain control during dressing changes continues to be a major challenge in patients with burns. We investigated two different dressing modalities to compare how much pain the patient experienced during and after the dressing change. Patients with partial-thickness burns that required only topical wound care were assigned randomly to treatment with Acticoat (Smith and Nephew USA, Largo, FL) or silver sulfadiazine (AgSD). The outcome variable was pain during wound care, which was measured using visual analog pain scores. The mean visual analog pain scores for the wounds treated with Acticoat or AgSD wounds were 3.2 and 7.9, respectively (P < .0001; paired Student's t-test). In 41 of the 47 paired pain score observations, the pain in the wound treated with AgSD was perceived as greater than in the wound treated with Acticoat. Burn wound care with Acticoat is less painful than burn wound care with AgSD in patients with selected partial-thickness burns.Journal of Burn Care & Rehabilitation 26(4):344-7. · 2.42 Impact Factor
