Fetal Scalp Lactate

Systematic Review


Among women at term in labour is the measurement of fetal scalp lactate superior to fetal scalp pH in predicting adverse fetal/newborn outcomes and successful acquisition of a usable sample?


Measurement of fetal scalp lactate is equivalent to fetal scalp pH for clinical decision-making to avoid adverse neonatal outcomes.  Fetal scalp lactate sampling requires less time and is associated with fewer failed sampling attempts.  Further research is needed to determine optimal values to indicate risk for neonatal morbidity.
