Guidelines released in October by global health agencies* now also recommend diagnosing and triggering treatment for PPH, the leading cause of maternal deaths, when measured blood loss reaches 300 mL and any abnormal signs in pulse rate, blood pressure and shock index have been observed.
The new recommendation is particularly useful for low-resource settings, where delays are more likely to result in deaths, and is supported by the findings from the largest study (Gallos 2025) on this topic to date. The study by the World Health Organization and colleagues analyzed individual participant data of over 300,000 women from 12 datasets, including datasets associated with two studies (Mobeen 2011; Durocher 2019) contributed by Gynuity. Their meta-analysis found that measured blood loss below the conventional threshold of 500 mL (i.e. 300 mL or more), when combined with abnormal hemodynamic signs, accurately predicts women at risk of death or severe complications from excessive bleeding after childbirth.
