Randomized Controlled Trial Multicenter Study Clinical Trial
Frequency of hypotension and bradycardia during general anesthesia, epidural anesthesia, or integrated epidural-general anesthesia for total hip replacement.
To evaluate the frequency of hypotension and bradycardia during integrated epidural-general anesthesia as compared with general anesthesia or epidural anesthesia alone. ⋯ The induction of general anesthesia in patients with an epidural block up to T10 increased the odds of developing clinically relevant hypotension as compared with those patients who received no epidural block, and was associated with a twofold increase of the odds of hypotension as compared with the use of epidural anesthesia alone.

To review the new consensus guidelines for cardiac testing for the patient with cardiac disease scheduled for elective, noncardiac surgery, and their impact on cardiac functional testing. ⋯ The guidelines for stress test may be over-sensitive, and further prospective clinical studies are indicated.

Randomized Controlled Trial Comparative Study Clinical Trial
Clonidine as coadjuvant in eye surgery: comparison of peribulbar versus oral administration.
To determine whether the administration of peribulbar or oral clonidine would enhance analgesia and anesthesia in ophthalmologic surgery. ⋯ Despite the higher intraoperative blood cortisol levels, 30 microg peribulbar clonidine decreased the onset time to anesthesia, while 15 and 30 microg peribulbar clonidine prolonged the time to first rescue analgesics in patients under peribulbar block, without increasing the frequency of adverse effects. Conversely, oral administration of clonidine alone did not enhance anesthesia or analgesia following eye block, suggesting a local mechanism of action of clonidine.

Randomized Controlled Trial Clinical Trial
The effect of fentanyl on hemodynamic and bispectral index changes during anesthesia induction with propofol.
To investigate the changes in hemodynamics and hypnotic levels during propofol infusion and tracheal intubation with and without fentanyl. ⋯ Propofol administration 20 mg/kg/hr for 10 minutes is suitable in suppressing arousal reactions to tracheal intubation, but the addition of fentanyl is required to blunt the hemodynamic responses.
