Abstract

Objective: To determine if quantitative blood loss would correlate to predicted blood loss based on change in blood concentration of hemoglobin.

Conclusion: The correlation between calculated blood using modified Brecher’s formula showed poor overall correlation to quantitative blood loss. There was a higher correlation at blood loss greater than 1500 cc which is where estimated blood loss has been shown to be most poor. Possible reasons for this poor correlation include maternal factors influencing hemoglobin levels, gestational age, error in blood loss calculation, inaccuracy of Brecher’s formula in pregnancy.

Keywords: Postpartum hemorrhage, calculated blood loss, quantitative blood loss
