摘要
Background: Severe acute pancreatitis is a life-threatening disease. Patients with peripancreatic necrotic infection often require surgical removal of necrotic infected tissue and a wide debridement will cause blood loss and worsen the condition. Aim: To assess whether treatment with NovoSeven, a recombinant activated FVII (rFVIIa), could improve coagulation function and therefore reduce blood loss, blood transfusion and all-cause mortality during necrosectomy in patients with infected necrosis secondary to severe acute pancreatitis. Materials and Methods: Severe acute pancreatitis patients admitted to Nanjing Jinling Hospital for necrosectomy were enrolled and randomized to receive either standard treatment or standard treatment plus an intravenous infusion of rFVIIa (40 mu g per kilogram of body weight per hour) before operation. The prospectively defined primary end points were perioperative coagulation parameters (prothrombin time, activated partial thromboplastin time), blood transfusion unit and blood loss. The secondary end points were operation time, ICU stay and all-cause mortality at 28 days after the operation. Results: A total of 64 patients were enrolled (31 in the rFVIIa group and 33 in the control group). Treatment with rFVIIa was associated with a reduction in operation time, red blood cell and fresh froze plasma transfusion, blood loss and prothrombin time compared to the control group (p < 0.05 for all). Activated partial thromboplastin time and mortality were similar between the two groups (P > 0.05). Conclusion: Treatment with rFVIIa significantly improved the extrinsic coagulation function in patients with severe acute pancreatitis and was associated with decreased risk of bleeding. However, rFVIIa did not improve intrinsic coagulation or reduce over-cause mortality.
