hypotension induced by general anesthesia in hypertensive patients
Conditions
Interventions
Gold Standard:Collapsibility index of inferior vena cava diameter. The sensitivity and specificity of inferior vena cava in predicting hypotension during anesthesia induction were 90%
Index test:The rate of inferior vena cava transverse area collapse predicts hypotension in hypertensive patients induced by general anesthesia
