Introduction: the shock index, also known as the hemorrhagic shock index, is a scoring tool that combines clinical and hemodynamic parameters to assess the degree of shock and the severity of hemorrhage.
Objectives: to describe the importance of the shock index in obstetric hemorrhage for predicting complications associated with morbidity and mortality in obstetric patients.
Methods: a structured literature review was conducted in three stages, searching multiple databases while applying predefined selection criteria. After selection, the sources were analyzed for relevance and currency.
Development: obstetric hemorrhage is a severe complication that remains a significant challenge in maternal care and is one of the leading causes of maternal morbidity and mortality worldwide. In this context, the shock index has emerged as a potentially useful tool to predict complications in cases of obstetric hemorrhage. Its calculation allows for a rapid and objective assessment of the patient’s hemodynamic status, helping to identify those at higher risk of complications, with a value ≥0,9 indicating the need for massive blood transfusion.
Conclusions: the obstetric shock index is a key hemodynamic marker that allows estimation of hypovolemia, prediction of massive transfusion and blood loss, and guidance of management protocols, with values ≥0.9 correlating with an increased risk of complications and maternal morbidity and mortality.
