Objective To investigate the clinical characteristics and first aid of obstetrical hemorrhagic shock .Methods Forty-six patients with obstetrical hemorrhagic shock and other patients without obstetrical hemorrhagic shock were investigated retrospectively .The placenta previa , placental abruption, placenta accreta or placenta remnants , Uterine Atony, laceration of birth canal , coagulation disorder dysfunction , postpartum hemorrhage were analyzed .The main risk factors for hemorrhagic shock were analyzed , and the effect of comprehensive emergency measures were discussed .Results The rate of placenta previa , placental abruption , placenta accreta or placenta remnants , Uterine Atony, laceration of birth canal, coagulation disorder dysfunction were higher than those of the control group (P<0.05). The ratios of bleeding volume ranging in 750~1500 mL or 500~2000 mL were lower in the observed group than those of the control group (P<0.05), but the ratio was higher in the observed group when the patients bleeding volume >2000 mL compared with the control group (P <0.05).All of the patients were out of danger , and the rate of rescue success was 100%.Conclusion The main risk factors for hemorrhagic shock include placenta previa , placental abruption , placenta accreta or placenta remnants, Uterine Atony, laceration of birth canal , coagulation disorder dysfunction , postpartum hemorrhage .It helps to increase the rate of rescue success by effective rescue measures and prevention complications .%目的：探讨产科失血性休克（hemorrhagic shock， HS）的临床特点及急救方法。方法回顾性分析我院收治的46例产科HS危急重症产妇（试验组）和同期未发生HS的产妇（对照组）胎盘前置、胎盘早剥、胎盘残留或粘连、宫缩乏力、产道裂伤及产后出血等的发生情况，分析HS的主要危险因素，并探讨综合急救措施的救治效果。结果试验组胎盘前置、胎盘残留或粘连、胎盘早剥、宫缩乏力、产道裂伤及凝血机制障碍发生率均明显高于对照组（P＜0．05）；试验组出血量在800～1500 mL和1500～2000 mL HS患者明显低于对照组，当出血量＞2000 mL时，HS患者明显高于对照组（ P＜0．05）；所有46例HS产妇经抢救和治疗后均脱离危险，无一例死亡，抢救成功率为100％。结论胎盘前置、胎盘残留或粘连、胎盘早剥、宫缩乏力、产道裂伤、凝血机制障碍及产后出血等均为诱发产科HS的主要危险因素，及时采取有针对性抢救措施，同时进行并发症预防，能够有效地提高抢救成功率。
