Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
To our knowledge, there is one report about the association between sonographically assessed carotid artery diameter and intravascular volume, which raised recommendation for further studies including the interplay between carotid geometry and intravascular fluid status.
Aim of the study:
The aim of this work is to evaluate the accuracy of noninvasive techniques for assessment of intravascular volume status by Sonographic assessment of both the common carotid artery diameter (CCA) and the central venous pressure (CVP) in response to a bolus of crystalloid solution infusion and to find the correlation between CCA diameter and CVP as the primary outcome in adults patients after major surgeries who needs close assessment and maintenance of the intravascular volume status.

patients admitted ti surgical ICU after major surgery
patient admitted to surgical ICU after major surgery for post-operative close monitoring, assessment and resuscitation of the intravascular volume status
common carotid artery diameter measurement
measurement of common carotid artery diameter will be carried out two times: the initial measurement (pre-infusion) which is followed by infusion of crystalloid solution (Ringer lactate) 30 ml/min till reaching a total infusion volume of 7 ml/kg body weight then another ultrasound measurement will be taken (prost-infusion). Between these sequential measurements, the patient position will not be changed. The percentage increase in CCA diameter will be calculated using the formula: \[(dia-mpost/dia-mpre) × 100\] - 100 \[11\].
