建立分娩风险预警评估机制应对超大分娩量时产后出血的临床效果观察

Observation on the clinical effect of establishing early warning and evaluation mechanism of delivery risk in response of postpartum hemorrhage in super large delivery

目的分析针对出现超大分娩量时导致产后出血的情况建立分娩风险预警评估机制的临床效果。方法 300例分娩产妇,依据是否建立分娩风险预警评估机制分为研究组(建立分娩风险预警评估机制)与参照组(未建立分娩风险预警评估机制),各150例。比较两组产后出血例数以及产后24 h平均出血量、平均出血次数。结果研究组产后出血发生率5.3%(8/150)明显低于参照组的18.7%(28/150)(P<0.05)。研究组8例产后出血产妇产后24 h平均出血量为(730.9±251.5)ml,明显少于参照组28例产后出血产妇的(1120.6±501.5)ml(P<0.05)。研究组8例产后出血产妇平均出血次数为(1.0±0.5)次,明显少于参照组28例产后出血产妇的(2.5±1.2)次(P<0.05)。结论超大分娩量时对产妇建立起分娩风险预警评估机制具有良好的临床效果。

Objective To analyze the clinical effect of establishing early warning and evaluation mechanism of delivery risk in response of postpartum hemorrhage in super large delivery. Methods A total of 300 delivery women were divided by whether establishing early warning and evaluation mechanism of delivery risk or not into research group（establishing early warning and evaluation mechanism of delivery risk） and control group（without establishing early warning and evaluation mechanism of delivery risk）, with 150 cases in each group. Analysis were made on cases of postpartum hemorrhage, average volume of bleeding at 24 h postpartum and average postpartum times between the two groups. Results The research group had obviously lower incidence of postpartum hemorrhage as 5.3%（8/150） than 18.7%（28/150） in the control group（P〈0.05）. The research group had obviously less average volume of bleeding at 24 h postpartum in 8 cases as（730.9±251.5） ml than（1120.6±501.5） ml in 28 cases of the control group（P〈0.05）. The research group had obviously less average postpartum times in 8 cases as（1.0±0.5） times than（2.5±1.2） times in 28 cases of the control group（P〈0.05）. Conclusion Establishing early warning and evaluation mechanism of delivery risk shows good clinical effect in response of postpartum hemorrhage in super large delivery.
