Blood loss at delivery: how accurate is your estimation?
1School of Nursing and Midwifery, Flinders University Adelaide, Adelaide, South Australia 5001, Australia.
Midwives and doctors often underestimate postpartum hemorrhage by 30-50%. This study highlights the need for healthcare professionals to double their blood loss estimates over 500 ml to improve patient safety.
Area of Science:
- Obstetrics and Gynecology
- Maternal Health
- Clinical Research
Background:
- Accurate estimation of postpartum blood loss is crucial for managing hemorrhage.
- Underestimation of blood loss can lead to delayed or inadequate treatment.
- Existing literature suggests potential inaccuracies in visual estimation of blood loss.
Purpose of the Study:
- To review the literature on blood loss estimation at delivery.
- To investigate the accuracy of blood loss estimation by midwives and doctors in simulated scenarios.
- To identify potential biases in estimating postpartum hemorrhage.
Main Methods:
- Literature review on postpartum blood loss.
- Pilot study involving simulated delivery scenarios.
- Midwives and doctors estimated blood loss visually.
- Data analysis using simple frequency distribution.
Main Results:
- Healthcare professionals, including midwives and doctors, tend to underestimate blood loss.
- Estimated blood loss was underestimated by 30-50% in simulated deliveries.
- Significant discrepancies were observed between estimated and actual blood loss.
Conclusions:
- There is a consistent underestimation of blood loss by health professionals during delivery.
- Midwives and doctors require improved training and tools for accurate blood loss assessment.
- A recommendation is made for clinicians to double their estimated blood loss when exceeding 500 ml to mitigate risks associated with postpartum hemorrhage.

Monitoring Both Arms:
Monitoring BP in both arms during the initial assessment is advisable, as the systolic value may differ by five to ten mm Hg between arms. For subsequent BP assessments, use the arm with the higher reading.
