AB An  infant  has  a  serum  sodium  of  127  mEq/L,  below  the  normal  accepted  value  of  135  mEq/L.  The  incidence  of  hyponatremia  is  greater  than  hypernatremia  in  premature  infants.  Evidence  now  shows  it  is  a  serious  condition  in  very  preterm  infants  (<33  weeks'  gestation),  who  have  large  variations  of  the  serum  sodium  concentration,  as  they  are  at  risk  for  poor  neuromotor  outcome  at  2  years.  Preterm  infants  with  an  increased  risk  of  hyponatremia  from  sodium  restriction  show  impaired  growth  and  worse  neurodevelopment  at  10–13  years  of  age.  Hyponatremia  is  also  a  risk  factor  for  sensorineural  hearing  loss,  intracranial  hemorrhage,  and  cerebral  palsy.  Hyponatremia  in  infants  who  experienced  perinatal  birth  asphyxia  are  at  risk  for  an  increased  mortality.
