Design outcomes
Primary
| Measure | Time frame |
|---|---|
| To correlate preoperative caval aortic index and percentage decrease in mean arterial pressure after induction of general anesthesia in elderly patients. Timepoint: baseline, at 1 min after induction, at 2 min after induction, at 3 min after induction, immediately after intubation, at 5 min after intubation, at 10 min after intubation. | — |
Secondary
| Measure | Time frame |
|---|---|
| To compare the accuracy of preoperative values of caval aortic index and ratio of maximum diameter of Inferior Vena Cava (IVC) at the end of expiration and IVC Collapsibility index (dIVCmax/IVCCI) in prediction of hypotension after induction of general anesthesia in elderly patients. Timepoint: 1 year 6 months | — |
