Preoperative Evaluation of IVC Collapsibility Index and Caval Aorta Index After Induction of General Anesthesia
Sponsor: Ain Shams University
Summary
This study aims to assess the accuracy, repeatability, and reproducibility of preoperative evaluation of Inferior Vena Cava (IVC) collapsibility index and caval aorta index for prediction of hypotension after induction of general anesthesia.

Interventions
Inferior vena cava collapsibility index
Inferior vena cava (IVC) collapsibility index (IVCCI) will be measured. The IVCCI is calculated using the following formula: IVCCI = (maximum IVC diameter - minimum IVC diameter) / maximum IVC diameter \* 100
Caval Aorta Index
The Inferior vena cava (IVC): Ao index will be derived by taking the ratio of the maximum IVC diameter during expiration and the maximal abdominal aortic diameter during systole. \- The caval aorta index (IVC/Ao) is calculated using the following formula: IVC/Ao index = IVC diameter / aortic diameter.
