title: Desmopressin does not decrease blood loss and transfusion requirements in patients undergoing hepatectomy.
abstract: OBJECTIVE
  To determine the effects of desmopressin on coagulation and blood loss in patients undergoing elective partial hepatectomy.
  
  
  METHODS
  A randomized, controlled and double-blind study on 59 patients who received either 0.3 micro g x kg(-1) of desmopressin or an equal volume of normal saline (control) infused intravenously over 20 min after induction of general anesthesia.
  
  
  RESULTS
  There was an increase in plasma levels of factors VIII and von Willebrand after the infusion of study drug in both groups (P < 0.001). The activated partial thromboplastin time was shortened in Group D whereas prothrombin time was prolonged in Group C; (P = 0.02). A large range of intraoperative blood loss (400-7128 mL) was observed, with no significant differences between groups. There were no changes in plasma electrolyte levels or osmolality. Transfusion requirements were similar in both groups.
  
  
  CONCLUSIONS
  Desmopressin did not reduce intraoperative blood loss or transfusion requirements during hepatectomy despite raising clotting factor levels and improving tests of hemostasis.
