To compare shock index (SI) values between women who required blood transfusion due to postpartum hemorrhage (PPH) and women who did not.
In a case-control study, clinical data were assessed from the medical records of women requiring blood transfusion for PPH at a center in Brazil between 2012 and 2015 (n=105). A control group was randomly selected from women who did not receive blood transfusion (n=129).
Compared with women who did not receive a transfusion after delivery, women who did receive one had significantly higher SI values 10 minutes after delivery (0.81 ± 0.27 vs 0.72 ± 0.16; P=0.012), at 30 minutes (0.83 ± 0.26 vs 0.71 ± 0.15; P<0.001), and at 2 hours (0.84 ± 0.27 vs 0.70 ± 0.14; P=0.032). For vaginal deliveries, SI values were significantly different at 30 minutes (0.88 ± 0.26 vs 0.71 ± 0.14; P<0.001) and 2 hours (0.90 ± 0.23 vs 0.72 ± 0.14; P=0.001). No significant differences were found for cesarean delivery.
The SI might be useful to identify early vital sign changes due to PPH. Increased SI values were associated with need for transfusion in vaginal deliveries.
比较因产后出血(PPH)需要输血的女性和未输血的女性的休克指数(SI)值。
在一项病例对照研究中,评估了 2012 年至 2015 年期间巴西某中心因 PPH 输血的女性(n=105)的病历中的临床数据。从未输血的女性(n=129)中随机选择了对照组。
与分娩后未输血的女性相比,接受输血的女性在分娩后 10 分钟(0.81±0.27 vs 0.72±0.16;P=0.012)、30 分钟(0.83±0.26 vs 0.71±0.15;P<0.001)和 2 小时(0.84±0.27 vs 0.70±0.14;P=0.032)时的 SI 值明显更高。对于阴道分娩,30 分钟(0.88±0.26 vs 0.71±0.14;P<0.001)和 2 小时(0.90±0.23 vs 0.72±0.14;P=0.001)时的 SI 值也存在显著差异。剖宫产时无显著差异。
SI 可能有助于识别因 PPH 引起的早期生命体征变化。SI 值增加与阴道分娩时需要输血有关。
