AB Postoperative  bleeding  is  a  dreaded  surgical  complication.  More  often  than  not  you  will  hear,  “It  was  dry  when  we  closed…”  as  your  surgical  colleagues  struggle  to  identify  the  source.  Risk  factors  include  trauma,  coagulopathy,  or  factor  deficiency,  which  may  be  congenital  or  acquired  from  malnutrition,  antibiotic  use,  or  liver  disease.  Hospitalized  patients  are  commonly  anticoagulated  prior  to  surgery.  Patients  at  risk  should  have  a  preoperative  evaluation  including  a  complete  blood  count,  liver  function  tests,  prothrombin  time,  activated  partial  prothrombin  time,  and  international  normalized  ratio  (Figure  45-1).  Patients  with  platelet  dysfunction  from  aspirin,  antiplatelet  agents,  or  uremia  are  also  at  increased  risk  of  postoperative  hemorrhage.
