Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
Effects of intravenous and oral clonidine on hemodynamic and plasma-catecholamine response due to endotracheal intubation.
To investigate the effects of intravenous (IV) versus oral clonidine on alterations of heart rate (HR), mean arterial pressure (MAP), cardiac output (CO), and plasma-catecholamines due to endotracheal intubation. ⋯ In conclusion, IV clonidine reduced stress response to endotracheal intubation compared with placebo. Oral clonidine at the dose used was less effective in blunting hemodynamic stress response than IV clonidine.

Clinical Trial Controlled Clinical Trial
Echocardiographic evaluation of global left ventricular function during high thoracic epidural anesthesia.
To assess the effects of high thoracic epidural anesthesia on left ventricular (LV) diastolic filling and systolic function in patients without heart disease. ⋯ High thoracic epidural anesthesia causes a decrease in CO without changing LV ejection and diastolic filling performance in healthy subjects.

Comparative Study Clinical Trial Controlled Clinical Trial
Superiority of multi-orifice over single-orifice epidural catheters for labor analgesia and cesarean delivery.
To investigate whether a change from a single-orifice to multi-orifice catheter could reduce the incidence of inadequate epidural blocks requiring replacement of the epidural catheter in obstetric patients. ⋯ The multi-orifice design offers significant advantages over the single-orifice type for obstetricepidural analgesia.

To survey cost containment activities in anesthesiology and to determine to what extent departments use cost policies and guidelines. ⋯ Anesthesiology departments are experiencing pressure to reduce costs and the majority have cost policies and guidelines concerning utilization of ORs and anesthetic drugs. Academic anesthesiology departments may be experiencing more cost-containment pressure than nonacademic departments.
