Table 5 Receiver operating characteristic (ROC) analysis to predict spinal anesthesia-induced hypotension.
AUC | 95% CI | P value | Threshold | Sensitivity (%) | Specificity (%) | |
---|---|---|---|---|---|---|
CBF in semirecumbent (mL/min) | 0.754 | 0.612–0.865 | 0.001 | ≤492.6 | 76.5 | 75.8 |
Mitral inflow E velocity (cm/s) | 0.775 | 0.634–0.881 | ≤59 | 82.4 | 75.8 | |
Medial E′ (cm/s) | 0.676 | 0.529–0.802 | 0.032 | ≤5 | 64.7 | 72.7 |
Level of sensory block at 5 min | 0.719 | 0.574–0.837 | 0.001 | ≤T6 | 52.9 | 78.8 |
CBF – carotid blood flow; AUC – area under the curve; CI – confidence interval; T – thoracic spine. |
