“…According to their report, SI was highest within 20 minutes after delivery and tended to decrease with time. And the average SI values was 0.82 ± 0.14 and 0.79 ± 0.13 in the preterm birth range from 33 to 36 weeks and after 37 weeks, respectively [9]. Similarly, HL.…”

Background : Although the SI (Shock index; heart rate / systolic blood pressure) is a useful indicator in the management of PPH (postpartum hemorrhage), there are few reports of SI in pregnant women with complicated with HDP (hypertensive disorder in pregnancy) cases. HDP patients have a high systolic blood pressure and the bleeding volume may not be reflected in SI. The purpose of this study was to examine whether SI and ΔSI (peak SI−baseline SI) would be clinically useful indicators, and to detect the cut-off value for judging abnormal obstetric bleeding. Methods: Retrospective case-control study in 107 patients with HDP in an single perinatal medical center. The values of prepartum SI, postpartum highest SI (peak SI), and the amount of bleeding until peak SI were retrospectively examined. The Kruskal-Wallis test was used to determine the relationship between peak SI, ΔSI and the amount of bleeding until peak SI. ROC(receiver operatorating characteristic) analysis was performed to determine the cut-off value. Results: Both peak SI and ΔSI were significantly related to the amount of bleeding up to peak SI (p <0.001). ROC analysis showed a cut-off values of peak SI where the amount of bleeding exceeded 500ml, 1,000ml, and 1,500ml. The values are 0.77 (sensitivity 64%, specificity 84%; AUC 0.81), 0.76 (sensitivity 87%, specificity 69%; AUC 0.86), 0.99 (sensitivity 100%, specificity 91%; AUC 0.97). And ΔSI, respectively, were 0.25 (sensitivity 66.6%, specificity 88.7%; AUC 0.84), 0.31 (sensitivity 81%, specificity 87.9%; AUC 0.91), and 0.43 (sensitivity 100%, specificity 93.1%; AUC 0.98).Conclusion: In HDP cases, if the peak SI is greater than 0.99, similar to non-HDP pregnancies, or if the ΔSI is greater than 0.43, we need to recognize it as bleeding of 1,500ml or more. In addition, ΔSI may be a more sensitive and specific indicator than conventional peak SI in HDP cases.

“…They concluded that SI 0.9 or higer required caution, and 1.7 or higer was urgent state [11]. Thus, evidence has been accumulated on the management of PPH in normal pregnancy, but there are few reports on the management of PPH in cases of complications or abnormal pregnancy, and this is the research task from now on [9].…”

“…11 Thus, evidence has been accumulated on the management of postpartum blood loss in normal pregnancy, but there are few reports on the management of postpartum blood loss in cases of complications or abnormal pregnancy, and this is the research task from now on. 9 Our study has several limitations. First, this study is a small, short-term retrospective case-control study in a singleton tertiary perinatal medical facility.…”

“…And the average SI values was 0.82 AE 0.14 and 0.79 AE 0.13 in the preterm birth range from 33 to 36 weeks and after 37 weeks, respectively. 9 Similarly, Nathan et al reported blood pressure and SI of 316 pregnant women with less than 500 ml of blood loss volume up to 1 h after delivery. The median SI was 0.66 (0.52-0.89), indicating that the normal SI value up to 1 h after delivery was less than 0.9 (the risk of serious consequences increases with SI value of 0.9 or higher).…”

Background: Although the shock index (SI) (heart rate/systolic blood pressure) and heart rate (HR) are a helpful indicator in the management of postpartum blood loss, there are few reports of SI in pregnant women complicated with hypertensive disorders in pregnancy (HDP). The purpose of this study was to examine whether SI and HR would be a clinically helpful indicator, and to detect the cutoff value for judging abnormal obstetric bleeding. Methods: This was a retrospective case-control study in 107 patients with HDP in a singleton tertiary perinatal medical facility. The values of postpartum highest SI (peak SI) and highest HR (peak HR), and the amount of bleeding until peak SI and peak HR were retrospectively examined and analyzed. We used the receiver operating characteristic analysis to assess the diagnostic value of peak SI and peak HR for judging abnormal obstetric bleeding. Results: Peak SI and peak HR were significantly related to the amount of bleeding up to peak SI and up to peak HR. The cutoff values of peak SI with blood loss volumes above 500 ml, 1000 ml, and 1500 ml were 0.77, 0.76, and 0.99, respectively. The cutoff values of peak HR with blood loss volumes above 500 ml, 1000 ml, and 1500 ml were 97, 98, and 103, respectively. Conclusion: In cases of pregnant women complicated with HDP, both SI and HR were probably useful indicators in the management of postpartum blood loss. Further prospective trials are warranted to confirm these results.
