About

Administration of intravascular fluids is one of the methods to prevent SA-induced hypotension, but empirical intraoperative volume repletion carries the risk of fluid overload during elective surgery. Over fluid resuscitation is associated with organ dysfunction and higher mortality rate , thus, to avoid ineffective or even harmful intravascular volume expansion, it is important to have tools to predict hypotension and fluid responsiveness.
