Abstract:

Postpartum hemorrhage is a leading cause of maternal death in China.Early diagnosis and prompt initiation of shock resuscitation are key to restoring the maternal circulating blood volume and avoiding maternal mortality.Due to the physiological changes in circulating blood volume during pregnancy，the signs of shock in severe postpartum hemorrhage are no longer typical，which can easily be overlooked clinically，thus losing the best opportunity for rescue.Volume resuscitation is essential for maintaining maternal hemodynamic stability， including active resuscitation and restrictive fluid resuscitation.Clinically，restrictive fluid resuscitation should be chosen while actively clarifying the etiology of postpartum hemorrhage and preparing for blood or component transfusion.Transfusion should be initiated promptly following volume resuscitation to supplement red blood cells，coagulation factors，etc.，maximizing the resuscitation efficacy and minimizing side effects.This article discusses the volume resuscitation of postpartum hemorrhage from the following aspects：pathophysiological characteristics of postpartum hemorrhage，early treatment，volume resuscitation plans，types and selection of resuscitation fluids，and complications of resuscitation，aiming to provide more basis for the early diagnosis and rescue of postpartum hemorrhage，thereby reducing the risk of maternal death.
