ABSTRACT
Objective: To determine the cut-off point of obstetric shock index associated with
massive transfusion in women with obstetric hemorrhage.
Materials and Methods: We designed a cross-sectional study in women who
were admitted to the intensive care unit. The obstetric shock index was calculated at the
time of the diagnosis of obstetric hemorrhage. We analyzed vital signs, arterial blood
gas, loss of blood, fluid replacement and transfused blood products.
Results: One hundred and five women with obstetric bleeding were included, in
65 (61%) the obstetric shock index was ≥ 0.9, of whom 38 (58%) needed massive
transfusion. Obstetric shock index ≥ 0.9 was significantly associated with massive
transfusion (p ‹ 0.001). The blood loss was of 3000 mL (RIC 2000 mL) in the patients
with obstetric shock index ≥ 0.9 compared to 2500 mL (RIC 1000 mL) in patients
with obstetric shock index ‹ 0.9 (p = 0.04). Women with obstetric shock index ≥ 0.9
showed more significant requirement of transfusion of package red blood (p = 0.03)
and platelets (p = 0.01).
Conclusions: An obstetric shock index ≥0.9 was associated with high transfusion
requirements and a higher incidence of serious adverse events, this value is recommended
as the cut-off point for predicting the need for massive transfusion.
