Summary

Based on the preoperative ultrasound detection of various parametric indicators of the inferior vena cava cross-section, including the ratio of the inferior vena cava's long and short axes, cross-sectional area and circumference during two-dimensional and three-dimensional imaging, as well as the changes in respiratory variability of each parameter, we explored the predictive value of IVC ultrasound indicator parameters on hypotension after induction of general anesthesia in elderly patients undergoing elective non-cardiac surgery, screened the sensitive indicators, and calculated the cut-off values.
