The Validity of Peripheral Perfusion Index to Predict Fluid Responsiveness

Fluid therapy is an essential component of the management of patients with acute circulatory failure. Nevertheless, unnecessary administration of fluids in non-responders is harmful. Thus, the concept of fluid responsiveness has been suggested to guide fluid administration in critically ill patients to avoid either over or under-transfusion. The aim of this work is to investigate the ability of peripheral perfusion index to predict the hemodynamic response to mini-fluid challenge in patients with septic shock .
