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.

Randomized Controlled Trial Comparative Study Clinical Trial
Removal of the laryngeal mask airway in children: deep anesthesia versus awake.
To compare the incidence of adverse airway events identified with removal of the laryngeal mask airway (LMA) from an awake child or from a child before his or her airway reflexes had returned. ⋯ Removal of the LMA during anesthesia and after return of airway reflexes results in a similar incidence of airway problems in children.

Randomized Controlled Trial Comparative Study Clinical Trial
Postoperative analgesia using a low-dose, oral-transdermal clonidine combination: lack of clinical efficacy.
To determine if a lower than previously reported oral-transdermal clonidine regimen could reduce postoperative morphine requirements without producing systemic side effects. ⋯ The low-dose oral-transdermal clonidine regimen evaluated failed to reduce postoperative morphine requirements, although patients who received clonidine were still at risk for developing hypotension.
