Appropriateness of Fluid Therapy in Cardiogenic Shock Management: A Systematic Review of Current Evidence

Fluid therapy plays a pivotal role in maintaining tissue perfusion during the management of cardiogenic shock. Nevertheless, its application in this context is contentious, necessitating a balance between achieving adequate volume and avoiding fluid overload. This systematic review aimed to assess the outcomes of fluid therapy in cardiogenic shock. This review encompasses 11 studies involving 406 participants. Although some studies reported hemodynamic improvements following fluid administration, others presented contrasting findings. Studies that did not highlight the benefits of fluid therapy typically involved patients with unique comorbidities requiring specific etiology-based medical treatments. The most prevalent cause of cardiogenic shock, acute coronary syndrome, exhibited varying responses to fluid therapy based on the infarct location. In conclusion, fluid therapy plays a crucial role in cardiogenic shock management but necessitates integration into an appropriate treatment strategy, accounting for individual circumstances, comorbidities, and etiology. Further research is imperative to amass additional evidence regarding this issue.
