AB The  clinical  syndrome  of  transient  tachypnea  of  the  newborn  (TTN)  is  caused  by  persistence  of  fetal  lung  fluid  in  the  neonate.  Other  terms  for  this  syndrome  include  wet  lung  disease,  transient  respiratory  distress  of  the  newborn,  and  neonatal  retained  fluid  syndrome.  Transient  tachypnea  is  the  most  common  of  the  various  causes  of  respiratory  distress  in  term  newborns  (Table  2-1).1  Factors  that  are  associated  with  an  increased  risk  for  transient  tachypnea  include  prolonged  labor,  cesarean  section,  narcotic  depression,  maternal  asthma,  and  maternal  diabetes.2,3  Typically,  the  infant  is  clinically  normal  immediately  after  delivery,  but  becomes  tachypneic  over  the  next  few  hours.  Despite  the  signs  of  mild  to  moderate  respiratory  distress,  there  is  usually  normal  oxygenation.  As  the  name  indicates,  TTN  is  typically  a  self-limited  process.
