AB The  accurate  definition  and  reporting  of  perinatal  deaths  (ie,  fetal  and  neonatal  deaths)  is  a  critical  first  step  in  understanding  the  magnitude  and  causes  of  these  important  events,  and  in  ultimately  reducing  mortality  and  morbidity.  Infant  mortality  is  an  important  outcome  measure  of  the  health  services  of  a  population.  In  the  United  States,  where  there  are  approximately  4  million  births  each  year,  the  infant  mortality  is  around  6  per  1000  live  births.  The  highest  risk  period  for  infant  death  is  within  24  hours  of  birth,  but  mortality  and  morbidity  rates  remain  high  during  the  neonatal  period,  until  the  28th  day  of  life.  The  fetus  and  newborn  are  most  vulnerable  during  labor,  delivery,  and  the  neonatal  period  because  central  nervous  system  injury  may  result  in  lifelong  morbidity  and  neurodevelopmental  impairment.  The  perinatal  period,  from  28  weeks  of  gestation  to  the  28th  day  of  life,  is  the  period  of  greatest  mortality.  In  the  modern  era,  with  survival  of  extremely-low-birth-weight  (ELBW)  infants,  postneonatal  mortality  also  contributes  significantly  to  the  infant  mortality  rate  (IMR).
