Abstract:
Aim: To determine the accuracy of the estimation of blood loss using simulated clinical examples.
Setting: Over 100 attendees came together at a seminar about postpartum haemorrhage in June
2006. Five blood loss assessment stations were constructed, each containing a simulated clinical
example. Each station was numbered and was made up of a variety of equipment used in birthing
suites. Over 5 L of ‘artificial’ blood was made. The artificial blood was similar to the colour and
consistency of real blood.
Sample: A convenience sample of 88 participants was given a response sheet and asked to
estimate blood loss at each station. Participants included midwives, student midwives and an
obstetrician.
Results: Blood in a container (bedpan, kidney dish) was more accurately estimated than blood on
sanitary pads, sheets or clothing. Lower volumes of blood were also estimated correctly by more
participants than the higher volumes.
Discussion: Improvements are still needed in visual estimation of blood loss following childbirth.
Education programs may increase the level of accuracy.
Conclusion: We encourage other clinicians and educators to embark upon a similar exercise to
assist midwives and others to improve their visual estimation of blood loss after birth. Accurate
estimations can ensure that women who experience significant blood loss can receive appropriate
care and the published rates of postpartum haemorrhage are correct.
