Comparison of maximum and minimum diameter of IVC and its collapsibility index between patients who developed and who did not develop hypotension after induction
| Parameter | No hypo tension (n=71) | Hypotension (n=17) | P (95% confidence interval) |
|---|---|---|---|
| IVCmax (cm) | 1.43±0.36 | 1.48±0.29 | 0.57 (−0.24 - 0.13) |
| IVCmin (cm) | 0.77±0.32 | 0.81±0.36 | 0.65 (−0.22 - 0.14) |
| IVC collapsibility Index (proportion) | 0.47±0.14 | 0.47±0.15 | 0.89 (−0.07 - 0.08) |
Values are expressed in mean±SD. Values with *denotes significant P. IVCmax: maximum diameter of inferior vena cava; IVCmin: minimum diameter of inferior vena cava; cm: centimetre; CI: confidence interval
