Goal-Directed Fluid Therapy in Patients Undergoing Lower Limb Surgeries

Effects of Goal-Directed Fluid Therapy Guided by Inferior Vena Cava Collapsibility Index on Hemodynamics and Enhanced Recovery in Patients Undergoing Lower Limb Surgeries

Controlling the amount of fluids given to patients in perioperative setting can significantly influence their outcomes.

To overcome these problems and avoid the complications of over or underhydration, we use the Goal-directed fluid therapy(GDFT) guided by Inferior vena cava(IVC) collapsibility index approach in which dynamic parameters of volume responsiveness as a guide for fluid therapy. This will ensure that the fluids given were deficient from the circulation and improve the recovery of the patients according to enhanced recovery after surgery(ERAS) protocols.
