Clinical Trial Summary

The study will be conducted to asses preoperative condition of venous system by VExUS score and it's relation with the incidence of spinal induced hypotension in geriatric patients undergoing surgery with spinal anaesthesia.


Clinical Trial Description

An assessment of the intravascular volume deficit prior to the spinal anaesthesia conduction may help to predict the occurrence of a critical decrease in blood pressure, so several indices have been proposed to assess it's status depending on either a fluid challenge or an assessment of heart-lung interaction. Heart rate variability, passive leg raise test, and peripheral perfusion index have revealed good abilities to predict spinal induced hypotension. The inferior vena cava (IVC) collapsibility index provides high diagnostic accuracy in predicting spinal induced hypotension The VeXUS score is a four-staged validated protocol which evaluates the presence and severity of systemic venous congestion in the inferior vena cava (IVC) and organs (liver, gut, and kidneys) by evaluating the (IVC) diameter, venous waveforms of the hepatic vein (HV), portal vein (PV), and interlobar renal veins using colour Doppler (CD) and pulsed wave Doppler (PWD) ;
