To investigate the effect of different plasma levels of fentanyl on the concentration of propofol and the Bispectral Index (BIS) required for patients to regain consciousness and orientation following surgery. ⋯ The plasma levels of fentanyl affect the concentrations of propofol required for patients to regain consciousness. The BIS values for wakefulness are unaltered at the different combinations of propofol and fentanyl concentrations. Thus, the BIS appears to be a useful and consistent indicator for level of consciousness during emergence from propofol/fentanyl intravenous anesthesia.

We report a case of epidural catheter shearing, an uncommon complication of removal of a wire-reinforced epidural catheter. The catheter was removed without incident, and with the tip intact, after we allowed the patient to relax for 3 hours, placing the patient in the lateral decubitus position, and placing continuous tension on the catheter itself so as to let it "work its way out".

Randomized Controlled Trial Clinical Trial
Aprotinin reduces vasoactive medication use during adult liver transplantation.
To determine whether aprotinin use during adult liver transplantation results in an improvement in hemodynamic stability. ⋯ Aprotinin infusion during adult liver transplantation results in less requirement for vasoactive intervention.

Case Reports
Acoustic reflectometry detection of an endobronchial intubation in a patient with equal breath sounds.
Acoustic reflectometry can be used to distinguish between a tracheal and an esophageal intubation based on an area-distance profile. In a patient undergoing laparoscopic surgery, acoustic reflectometry was used to detect a bronchoscopically confirmed endobronchial intubation in the presence of equal bilateral breath sounds. An in vitro simulation suggests that in an endobronchial intubation, in the presence of a space leak between the tube cuff and the bronchus, an acoustic pressure disturbance can be transmitted to the opposite lung (causing equal breath sounds), without significant bulk airway flow (causing inadequate ventilation of the opposite lung).
