简要总结
Hypertensive patients have more hemodynamic instability during general anesthesia than do patients with NORMOTENSION. In this study, the investigators evaluated the usefulness of carotid ultrasound and inferior vena cervical ultrasound for predicting hypotension after induction of anesthesia in patients with hypertension.
详细描述
Carotid and venous ultrasonography is performed in a comfortable state. Corrected blood flow after carotid ultrasound and carotid artery blood flow rate were measured.
After inferior vena cava sonography, using the embedded software, the collapsibility Index by measuring the largest and smallest diameter during the respiratory cycle will be obtained.
After confirming baseline blood pressure and pulse rate, propofol 2 mg / kg is administered and remifentanil is maintained at 4.0 ng / mL using the Target Control System (TCI).
Following the administration of rocuronium 1.0-1.2 mg / kg, and 1 minute and 30 seconds after BIS 60 or less, endotracheal intubation is performed using video laryngoscope.
Blood pressure and heart rate are measured at prior to induction, 1 minute after the induction, immediately after intubation, and at 1, 3, 5, 7 and 10 minutes after intubation.
