Abstract Background Hypotension is often occurring after induction of general anesthesia (IGA) and can cause organ hypoperfusion and ischemia which associated with adverse outcomes in patients having both cardiac and non-cardiac surgery. Elderly patients are particularly more vulnerable and at increased risk to the depressant effect of anesthetic drugs. So, recognition and prevention of such event are of clinical importance. This study recruited patients aged above 60 years, with ASA physical status classification I-II-III who were scheduled for surgery under general anesthesia with the aim to assess the effectiveness of preoperative IVC ultrasonography in predicting hypotension which develops following IGA and its association with the volume status in elderly patients receiving general anesthesia, through measurements of the maximum inferior vena cava diameter (dIVCmax), minimum inferior vena cava diameter (dIVCmin), inferior vena cava collapsibility index (IVC-CI), and basal and post-induction mean arterial pressure (MAP). Results Thirty-nine (44.3%) of the 88 patients developed hypotension after IGA, and it was significantly more in patients who did not receive preoperative fluid (p = 0.045). The cut-off for dIVCmax was found as 16.250 mm with the ROC analysis. Specificity and sensitivity for the cut-off value of 16.250 mm were calculated as 61.2% and 76.9%, respectively. The cut-off for IVC-CI was found as 33.600% with the ROC analysis. Specificity and sensitivity for the cut-off value of 33.600% were calculated as 68.7% and 87.2%, respectively. Conclusions IVC ultrasonography may be helpful in the prediction of preoperative hypovolemia in elderly patients in the form of high IVC-CI and low dIVCmax. The incidence of hypotension was lower in patients who received fluid infusion before IGA.

Abstract Background: To evaluate the use of inferior vena cava diameter (IVCD) to predict post-induction of general anesthesia (IGA) hypotension in older patients. Methods: Part I involved 60 older patients undergoing general anesthesia for surgery (group T).We determined the optimal cutoff value (OCV) of the most sensitive index (MSI) (the collapsibility index (IVCci), distensibility index, or respiratory variation rate) that best predicted post-IGA hypotension in older adult patients. Part II involved 66 older adult patients who underwent general anesthesia for surgery. In accordance with the MSI determinde in part I, patients were divided into group B (MSI ≥ OCV, n=42) and group S (MSI
