Background: Hemodynamic support using vasoactive agents is a mainstay in the management of patients with pediatric fluid-refractory septic shock (FRSS). However, evidence supporting the appropriate choice of vasoactive agent is limited. This study aimed to perform a systematic review and meta-analysis on the effect of different first-line vasoactive strategies on mortality in pediatric FRSS. ⋯ Interpretation: Among children with FRSS receiving a single vasoactive agent, norepinephrine was associated with the lowest mortality rate. Comparing dopamine and epinephrine, patients receiving epinephrine needed less mechanical ventilation and showed a trend for lower mortality rate. Further research is needed to better delineate the first-line vasoactive agent in this population.

Postpartum hemorrhage is the leading cause of preventable maternal illness and death globally and carries a disproportionately high burden of mortality in low- to middle-income countries. Tranexamic acid, an antifibrinolytic drug, has been widely adopted to control bleeding in trauma and other surgical conditions. ⋯ However, despite these guidelines and the proven utility of tranexamic acid to treat postpartum hemorrhage, widespread adoption of tranexamic acid into global standards of care across professional organizations has not been achieved. It is important for healthcare providers to understand the etiologies of postpartum hemorrhage, the mechanism of action and adverse effect profile of tranexamic acid, and the available literature regarding the use of tranexamic acid to prevent and treat postpartum hemorrhage to provide the best care for the pregnant patient.

Pelvic fractures are severe traumatic injuries often accompanied by potentially fatal massive bleeding. Rapid control of hemorrhages in prehospital emergency settings is critical for improving outcomes in traumatic bleeding. Resuscitative endovascular balloon occlusion of the aorta (REBOA) is a promising technique for controlling active bleeding from pelvic fractures. ⋯ This paper provides a comprehensive overview of the initial management of noncompressive trunk hemorrhage caused by pelvic fractures, introduces the technical principles and developments of REBOA, and explores its extensive application in prehospital emergency care. It delves into the operational details and outlines strategies for effectively managing potential complications. We aim to offer a theoretical framework for the future utilization of REBOA in managing uncontrollable hemorrhage associated with pelvic fractures in prehospital emergencies.
