title: Fetal blood gas analysis from cordocentesis for abnormal fetal heart rate patterns.
abstract: We present three cases with abnormal fetal heart rate patterns and cordocentesis umbilical venous blood gas analyses. Conflicting heart rate patterns and cordocentesis and postnatal blood gas analyses prompt questions with regard to abnormal fetal heart rate pattern interpretation and suggest that cordocentesis blood gas analysis aids perinatal management only as a reflection of fetal status at sampling time.
