Abstract
Abstract
Objectives
To compare the postpartum shock index (SI) values between pregnant women with hypertensive disease of pregnancy (HDP) and normotensive controls.
Methods
The present study was conducted in Ankara City Hospital Perinatology Clinic. Postpartum SI was compared between the pregnant women with HDP (n=217) and normotensive controls (n=219). A logistic regression analysis was performed to assess the independent predictors of maximum SI ≥1. Finally, a ROC analysis was performed to calculate optimal cut-off values for postpartum SI’s measured at different periods in the prediction of postpartum Hb (hemoglobin) decrease ≥2 g/dL.
Results
Peripartum SI (p<0.001), 15th min SI (p<0.001), 30th min SI (p<0.001), 2nd h SI (p<0.001), 6th h SI (p) of the HDP group (p<0.001) and max SI (p<0.001) values were found to be significantly lower in the study group. A weak positive and statistically significant correlation was found between the maximum SI and the decrease in Hb ≥2 g/dL (r=0.209; p=0.002). Optimal cutoff values for SI were; 0.7 at peripartum 0.7 at 15 min, 0.73 at 30 min, 0.6 at 2 h, and 0.7 at 6 h, respectively.
Conclusions
Clinically significant blood loss may develop at lower SI values in hypertensive pregnant women.
