The effects of dexmedetomidine on hemodynamic responses to tracheal ntubation in hypertensive patients: A comparison with esmolol and sufentanyl.

Background: Hypertension and tachycardia caused by tracheal intubation can be detrimental in hypertensive patients. This study was conducted in order to compare the effects of dexmedetomidine on hemodynamic response to tracheal intubation in hypertensive patients with esmolol and sufentanyl.

Methods: Sixty hypertensive patients scheduled for noncardiac surgery under general anesthesia were randomly assigned to receive one of the three drugs before induction of anesthesia.

Passiflora incarnata Linneaus as an anxiolytic before spinal anesthesia.

Purpose: Patients who undergo regional anesthesia experience anxiety in the preoperative period. Passiflora incarnata Linneaus is a plant that has traditionally been used as an anxiolytic and sedative. We aimed to investigate the effect of preoperative oral administration of Passiflora incarnata Linneaus on anxiety, psychomotor functions, sedation, and hemodynamics in patients undergoing spinal anesthesia.
