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).

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.

Randomized Controlled Trial Comparative Study Clinical Trial
The timing of electroconvulsive therapy and bispectral index after anesthesia induction using different drugs does not affect seizure duration.
To determine the association between bispectral index (BIS) and seizure duration obtained by electroconvulsive therapy (ECT) administered sooner or later after anesthetic induction. ⋯ The hypnotic drug effect measured by the BIS is not correlated to the seizure duration obtained by ECT.

Randomized Controlled Trial Comparative Study Clinical Trial
Stress hormones during the wake-up test in scoliosis surgery.
To compare hemodynamic and endocrine stress responses of two anesthetic regimes during intraoperative wake-up tests in scoliosis surgery. ⋯ Propofol-remifentanil anesthesia is equivalent to sevoflurane-remifentanil anesthesia for a wake-up test. Both the propofol- and sevoflurane-based anesthetic regimens abolish hemodynamic and endocrine stress responses to incision for scoliosis surgery in teenagers. Intraoperative wake-up testing is associated with substantial catecholamine stress despite virtually unchanged mean arterial pressure and heart rate.

Randomized Controlled Trial Comparative Study Clinical Trial
Bispectral monitoring during vital capacity rapid inhalation induction with sevoflurane.
To evaluate the variables of bispectral index (BIS) values during vital capacity rapid inhalation induction (VCRII) with sevoflurane. ⋯ VCRII with a high concentration of sevoflurane provided adequate BIS values during induction, suggesting that it may allow smoother transition from anesthesia induction to maintenance, and also maintain an adequate hypnotic level in readiness for certain stimuli such as laryngoscopy and tracheal intubation.
