AB  - Postpartum  hemorrhage,  or  excessive  blood  loss  following  delivery,  is  the  leading  cause  of  maternal  death  worldwide.  It  is  traditionally  defined  as  blood  loss  greater  than  500  mL  after  vaginal  delivery  and  1000  mL  after  a  cesarean  section.1  This  is  impractical  because  the  normal  blood  loss  is  believed  to  be  300  to  500  mL  following  a  vaginal  delivery  and  900  to  1200  mL  following  a  cesarean  section.2  It  has  also  been  defined  as  blood  loss  that  results  in  a  decrease  in  the  hematocrit  of  greater  than  10  points  between  admission  and  the  postpartum  period,  which  corresponds  to  the  97th  percentile  of  vaginal  and  92nd  percentile  of  cesarean  deliveries.1,2  A  clinically  useful  definition  is  excessive  bleeding  that  results  in  signs  and/or  symptoms  of  hypovolemia  (e.g.,  tachycardia,  hypotension,  oliguria,  dizziness,  palpitations,  syncope,  and/or  shortness  of  breath),  which  corresponds  to  a  10%  or  more  loss  in  total  blood  volume.3  Postpartum  hemorrhage  can  occur  at  sites  within  or  external  to  the  genitourinary  tract  (Table  135-1).
