To investigate whether motor evoked potentials (MEP) to transcranial electrical stimulation under constant blood propofol concentration are affected by the arousing effect of surgical noxious stimuli. ⋯ MEP to the transcranial electrical stimulation under a constant and clinically appropriate blood propofol concentration are not affected by surgical noxious stimuli.

Prediction of difficulty in orotracheal intubation (DI) in patients undergoing laryngeal microsurgery should help reduce the morbidity-mortality associated with this clinical situation. To establish a simple score to predict this difficulty, we studied 11 variables and their association with DI in these patients. ⋯ The index we describe is aimed at predicting DI in a very specific population with a high risk of this complication. This index uses a series of variables which may be measured easily during the preoperative period and provides an excellent predictive capacity with a high sensitivity and specificity when the index is > or = 5.

To assess the dose-dependent effect of low concentrations of isoflurane on respiratory mechanics in normal subjects. ⋯ Isoflurane concentrations between 0.6-1.2% are not associated to a dose-dependent effect on respiratory mechanics.

Continuous interscalene brachial plexus blockade (CIBPB) in a hospital setting can provide excellent surgical conditions and postoperative analgesia for major shoulder surgery. This is a case report of four patients on the efficacy and advantages of CIBPB for postoperative analgesia at home. ⋯ The use of CIBPB for 72 hr in patients undergoing major ambulatory shoulder surgery can result in good analgesia with minimal opioid requirement, cost savings and possibly improvement in outcome measures.
