title: Intrapartum asphyxia in the preterm fetus less than 2000 gm.
abstract: The incidence of intrapartum asphyxia in the preterm fetus less than 2000 gm (6%) is greater than that in the mature fetus (2%). Severe antepartum hemorrhage is the only clinical marker predictive of asphyxia in the preterm fetus. Marked deceleration patterns and particularly late decelerations may be of predictive value for asphyxia. However, many intrapartum asphyxial episodes are not identified on the basis of clinical observations. Consistent diagnosis of intrapartum asphyxia in the preterm fetus requires routine umbilical cord blood gas and acid-base assessment at delivery.
