Acute uterine inversion is a rare life-threatening complication of third stage of labour. In majority of cases, exact aetiology is unknown. It should be strongly suspected when the triad of haemorrhage, shock and severe abdominal pain with bearing down sensation is present after delivery of placenta. It can occur even after active management of third stage of labour. Diagnosis is essentially clinical. Expeditious manual repositioning of uterus and simultaneous liberal use of uterotonics is the management of choice. This was successfully attempted in the present case where a 26-year-old multiparous woman, without any identifiable risk factors, developed acute puerperal uterine inversion after active management of labour. It was observed that quick and accurate clinical judgement and timely intervention can prevent maternal mortality. The role of a multidisciplinary team including primary health care provider, obstetrician, anaesthesiologist and critical care experts has significant effects on outcome especially in intractable cases.
