Randomized Controlled Trial[Influence of inhaled nitrous oxide on the induction doses of propofol and thiopental assessed by auditory evoked potentials].
To assess the influence of 50% nitrous oxide (N2O) on the induction doses of propofol and thiopental by means of the auditory evoked potentials index (AAI). To evaluate the time to induction of anesthesia. ⋯ The doses of both thiopental and propofol are reduced and induction times are shorter when the drugs are administered with a mixture of 50% N2O and 50% oxygen. Monitoring the AAI facilitates the titration of thiopental and propofol dosing during anesthetic induction.

Case Reports[Intraoperative transesophageal echocardiography and systolic anterior motion of the mitral valve: findings during noncardiac surgery].
Systolic anterior motion is an under-recognized cause of acute systemic hypotension during noncardiac surgery. This dynamic event has come to light with the introduction of intraoperative transesophageal echocardiography, which provides anatomic and functional images in real time. The cause of this abnormal motion is still uncertain, although it is thought that changes in the shape and function of the left ventricle allow displacement of the mitral valve annulus so that 1 or more leaflets can be pulled toward the outflow tract and obstruct it during the systole. ⋯ The results of such measures can be monitored on intraoperative echocardiographic images. Volume replacement should increase the size of the ventricle and the beta-blockers should decrease the hyperdynamic state. We report a case of abnormal systolic motion during noncardiac surgery that was managed with the help of echocardiography.

Randomized Controlled Trial Comparative Study[Influence of neostigmine on the course of neuromuscular blockade with rocuronium or cisatracurium: a randomized, double-blind trial].
To compare the time-course of neuromuscular blockade with rocuronium or cisatracurium during intravenous anesthesia, in terms of both the time to spontaneous recovery or time to reversal after administration of neostigmine. ⋯ Not antagonizing a rocuronium- or cisatracurium-induced neuromuscular blockade in surgical procedures lasting less than 90 minutes can lead to a high percentaje of residual blockade (TOF ratio <80%).
