About this trial

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.

Time perspective

Prospective

Treatments tested in this trial

  • Inferior vena cava collapsibility index

    Other intervention

    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

    Other intervention

    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.
