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
Compound A concentration in the circle absorber system during low-flow sevoflurane anesthesia: comparison of Drägersorb Free, Amsorb, and Sodasorb II.
To determine compound A concentrations in a low-flow circuit containing Drägersorb Free (Dräger, Lübeck, Germany), Amsorb (Armstrong, Coleraine, Northern Ireland), and Sodasorb II (W. R. Grace, Lexington, MA). ⋯ Because compound A concentrations in the circuit with Drägersorb Free and Amsorb were negligible, sevoflurane can be used at a fresh gas flow of 1 L/min with these two absorbents.

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.
