Fetal heart rate monitoring often shows abnormal patterns that don’t reflect an underlying problem for the fetus. Research on fetal blood sampling has been limited. A recent study found weak correlations between fetal blood pH levels, umbilical cord pH levels and Apgar scores. It is vital that further research takes into account how fetal physiology actually works, rather than repeating inaccurate assumptions.
Today’s post reflects on a 1959 trial concerning “fetal distress”. It highlights findings that meconium was a critical indicator of poor outcomes, while abnormal fetal heart rates weren’t reliably predictive. Should we be reevaluating current obsessions with CTG use and focusing on alternative clinical markers?
When you have been using a test for years and years, you assume someone way back at the beginning did some pretty decent research to determine what numbers are “normal” and a sign of good health, and what numbers are “abnormal” and a sign of poor health. But is that always the case? Why do we test cord blood acid levels? The testing of fetal and neonatal blood acid levels […]
