To investigate the liquid resuscitation in approach to treatment of the obstetrical hemorrhagic shock. Methods: By a retrospective analysis of 64 cases of obstetrical hemorrhagic shock, to examine what, how much and when to transfuse and their results. Results: The patients were saved on condition that 1 500 ml buffered solution was transfused within one hour immediately after shock happened and whole blood, blood plasma and the coagulant were administrated in time to make the hemoglobin up to the level of 10 g and hematocrit 30%. The patients without timely increasing of their blood volume died of multiple system organ failures. Conclusion: The blood volume should be supplemented in time, rapidly and effectively. During the supplementation of blood volume, the principles of fast-to-slow, crystalsolution-to-colloidsolution and salinesolution-to-glucosesolution should be followed to furnish blood and oxygen with important organs, which is a key to a successful treatment.
