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.

Conditions

  • Inferior Vena Cava
  • Collapsibility Index
  • Caval Aorta Index
  • Induction
  • General Anesthesia
  • Craniotomy

Interventions

OTHER

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

OTHER

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.
