Structured PICO

Does using a lactate cutoff of 1.55 mmol/L improve accuracy in detecting acidic blood conditions compared to traditional pH measurements in babies during labor?

Population

Indian babies and mothers during labor with abnormal fetal heart rate patterns at a tertiary center

Intervention

Lactate-guided blood tests using a cutoff of 1.55 mmol/L

Comparator

Traditional pH measurements

Outcome

Accuracy in detecting acidic blood conditionssurrogate

A cord blood lactate cutoff of 1.55 mmol/L offers better diagnostic accuracy than traditional pH measurements for identifying acidic blood conditions in newborns, potentially guiding quicker delivery decisions in resource-limited settings.

Abstract

Abnormal heart rate patterns during labor are strongly linked to acidic blood conditions in Indian babies. Using improved lactate cutoff levels (1.55 mmol/L) provides better accuracy than traditional pH measurements. Quick delivery (within 30 min) for the most severe heart rate patterns, combined with lactate-guided blood tests, could improve outcomes for mothers and babies in hospitals with limited resources.
