Randomized Controlled Trial Comparative Study Clinical Trial
A comparison of techniques for placement of double-lumen endobronchial tubes.
To compare two methods of double-lumen endobronchial tube placement for thoracic surgery and to identify factors that provide a rational basis for placement method selection. ⋯ Both the blind and directed approaches resulted in successful left mainstem placement of the endobronchial tube in the majority of patients but either method may fail when used alone. More time was required using the directed approach. Operator experience with both methods will increase the likelihood of success. The choice of the initial approach may be influenced by patient factors as well as available equipment and personnel.

Randomized Controlled Trial Comparative Study Clinical Trial
Renal function in patients during and after hypotensive anesthesia with sevoflurane.
To evaluate renal function during and after hypotensive anesthesia with sevoflurane compared with isoflurane in the clinical setting. ⋯ Two hours of hypotensive anesthesia with sevoflurane under 5 L/min total gas flow in patients having no preoperative renal dysfunction transiently increased NAG, which is consistent with a temporary, reversible disturbance of renal tubular function.

Randomized Controlled Trial Clinical Trial
Consideration of the optimal epidural fentanyl doses in abdominal surgery.
To determine an optimal dose of epidural fentanyl in open abdominal surgery by examining the effects of different doses of epidural fentanyl in combination with or without low concentration of lidocaine on hemodynamic and endocrine responses to surgical stress. ⋯ Epidural fentanyl 3 micrograms/kg with 0.5% lidocaine may be most adequate for laparotomy because these doses caused neither bradycardia nor increments of norepinephrine perioperatively.

(1) To incorporate regional anesthesia options for common outpatient orthopedic surgery into clinical pathways; (2) to use the clinical pathway format and the Procedural Times Glossary published by the Association of Anesthesia Clinical Directors (AACD) as management tools to measure postoperative same-day surgery processes and discharge outcomes; and (3) to determine the effects of general, regional, and combined general-regional anesthesia on these processes and outcomes. ⋯ Clinical pathway regional anesthesia care for outpatient orthopedics may have a significant role in simultaneously containing costs and improving both process efficiency and patient outcomes.

(1) To introduce anesthesia clinical pathways as a management tool to improve the quality of care; (2) to use the Procedural Times Glossary published by the Association of Anesthesia Clinical Directors (AACD) as a template for data collection and analysis; and (3) to determine the effects of anesthesia clinical pathways on surgical processes, outcomes, and costs in common ambulatory orthopedic surgery. ⋯ Clinical pathway patient management systems in anesthesia care are likely to produce useful outcome data of current practice patterns when compared with historical controls. This management tool may be useful in simultaneously containing costs and improving process efficiency and patient outcomes.
