Controlled Clinical Trial
Forced-air warming effectively prevents midazolam-induced core hypothermia in volunteers.
Midazolam is a commonly used sedative and anaesthetic adjuvant and the agent is known to decrease core temperature by core-to-periphery redistribution of heat. We tested the hypothesis that forced-air warming could effectively prevent midazolam-induced hypothermia. ⋯ We conclude that forced-air warming can effectively prevent midazolam-induced redistribution hypothermia.

Randomized Controlled Trial Comparative Study
Learning curves of the Glidescope, the McGrath and the Airtraq laryngoscopes: a manikin study.
Several video and optical laryngoscopes have been developed but few have been compared in terms of their learning curves and efficacy. Using a manikin with normal airways we compared the Glidescope, the McGrath, the Airtraq and the Macintosh laryngoscopes. ⋯ In a 'normal airway' model, intubation skills with the new devices appeared to be rapidly mastered. The three indirect laryngoscopes provided a better glottic exposure than the Macintosh. The Airtraq displayed the most favourable learning curve, probably reflecting differences in the techniques of endotracheal tube placement: guiding channel versus steering technique.

Comparative Study
Acetaminophen-induced liver injury and oxidative stress: protective effect of propofol.
We evaluated the effects of propofol on oxidative stress and acute liver injury and regeneration produced by acetaminophen administration in rats. ⋯ The antioxidant capacity of propofol, verified in our study, did not manage to prevent liver injury and accelerate regeneration after acetaminophen administration in rats.

Controlled Clinical Trial
Skin impedance correlates to sedation grade, plasma propofol concentrations and bispectral index during a target-controlled infusion of propofol.
Sympathetic activity, measured as changes in electrical skin impedance, may be used to assess the adequacy of general anaesthesia. The aim of this prospective study was to evaluate electrical skin impedance in comparison with bispectral index values and the Observer's Assessment of Alertness and Sedation (OAAS) scale during propofol infusion. ⋯ The observed correlations between electrical skin impedance, predicted plasma concentrations of propofol and OAAS scale appear to justify further investigation of skin impedance as a depth of anaesthesia monitor.
