Hemorrhage is the leading cause of maternal mortality worldwide. A maternal health priority is improving how healthcare providers prevent and manage postpartum hemorrhage (PPH). Because anesthesiologists can help facilitate how hospitals develop approaches for PPH prevention and anticipatory planning, we review the potential utility of PPH risk-assessment tools, bundles, and protocols. Anesthesiologists rely on clinical and diagnostic information for initiating and evaluating medical management. Therefore, we review modalities for measuring blood loss after delivery, which includes visual, volumetric, gravimetric, and colorimetric approaches. Point-of-care technologies for assessing changes in central hemodynamics (ultrasonography) and coagulation profiles (rotational thromboelastometry and thromboelastography) are also discussed. Anesthesiologists play a critical role in the medical and transfusion management of PPH. Therefore, we review blood ordering and massive transfusion protocols, fixed-ratio vs. goal-directed transfusion approaches, coagulation changes during PPH, and the potential clinical utility of the pharmacological adjuncts, tranexamic acid, and fibrinogen concentrate.
出血是全球孕产妇死亡的主要原因。改善医疗保健提供者预防和处理产后出血 (PPH) 的方法是孕产妇保健的重点。由于麻醉师可以帮助医院制定 PPH 预防和预期计划的方法,我们回顾了 PPH 风险评估工具、捆绑包和方案的潜在效用。麻醉师依靠临床和诊断信息来启动和评估药物治疗。因此,我们回顾了产后出血量的测量方法,包括视觉、容量、重量和比色法。还讨论了评估中心血液动力学变化的即时护理技术(超声检查)和凝血谱(旋转血栓弹性描记术和血栓弹性图)。麻醉师在 PPH 的医疗和输血管理中起着至关重要的作用。因此,我们回顾了血液订购和大量输血方案、固定比例与目标导向输血方法、PPH 期间的凝血变化,以及药理学辅助物、氨甲环酸和纤维蛋白原浓缩物的潜在临床应用。
