AB Assisted  or  operative  vaginal  birth  refers  to  the  use  of  a  vacuum  or  forceps  to  achieve  a  vaginal  birth  in  the  second  stage  of  labor  for  fetal  or  maternal  indications.  When  deciding  whether  to  perform  an  assisted  vaginal  birth  (AVB),  considerations  must  include  indications  and  contraindications  to  the  procedure,  timing  and  choice  of  instrument,  the  maternal  or  fetal  risks  of  using  either  instrument,  the  urgency  of  the  need  to  expedite  delivery,  the  experience  and  skills  of  the  birth  attendant,  and  the  risks  associated  with  the  alternative  choice  of  cesarean  section  in  the  second  stage  of  labor.  Regardless  of  the  instrument  used,  the  indications  for  AVB  are  the  same.  The  operator  should  assess  the  safety  and  likelihood  of  success  by  considering  the  estimated  fetal  weight,  adequacy  of  the  maternal  pelvis,  fetal  station,  fetal  position,  and  adequacy  of  anesthesia  prior  to  use  of  either  forceps  or  the  vacuum.  AVB  should  only  be  attempted  if  there  is  a  reasonable  chance  of  success,  and  a  backup  plan  should  be  in  place  in  case  the  attempt  is  not  successful.  Forceps  or  vacuum  extraction  is  contraindicated  if  the  fetal  head  is  not  engaged  in  the  pelvis  or  if  the  fetal  position  cannot  be  determined.
