AB  - Fetal  urine  production  begins  at  10  to  13  weeks  gestation,  and  although  urine  production  increases  thereafter  throughout  pregnancy,  glomerular  filtration  rate  (GFR)  is  always  lower  in  preterm  infants.Renal  function  changes  quickly  in  the  fetus  and  newborn  with  an  increasing  GFR  and  tubular  maturity  leading  to  enhanced  concentrating  ability.Calculation  of  maintenance  fluid  requirements  is  size  dependent;  however,  practically,  calculations  are  more  typically  based  on  body  weight  rather  than  body  surface  area.Premature  infant  fluid  requirements  are  different  from  term  infant  requirements  in  both  total  fluid  volumes  and  electrolyte  content.To  avoid  serious  neurologic  injury,  sodium  abnormalities  should  not  be  corrected  quickly.
