Randomized Controlled Trial Comparative Study Clinical Trial[Comparison of an auditory evoked potentials index and a bispectral index versus clinical signs for determining the depth of anesthesia produced by propofol or sevoflurane].
To evaluate an anesthetic depth index (ADI) obtained from auditory evoked potentials and a bispectral EEG index (BIS) in comparison with clinical assessment of anesthetic depth using the modified observer's assessment of awareness/sedation scale (MOAA/SS), for induction of anesthesia with propofol or sevoflurane as the only agent. ⋯ Monitoring anesthetic depth with the ADI or BIS was technically easy and effective for detecting whether patients were awake or sleeping. The ADI response was faster and identified awake/sleeping and sleeping/awake phase changes better than did the BIS.

[Locoregional anesthesia for external ear surgery and postoperative analgesia].
To evaluate a change in the classical technique for local-regional anesthesia (periauricular "V" infiltration) for surgery on the outer ear, specifically adding a new infiltration of the osteocartilaginous juncture of the external acoustic meatus and the auditory foramen, as an alternative to general anesthesia in adults, including assessment of postoperative analgesia. ⋯ The described local-regional blockade of the outer ear used as the only anesthetic method, is indicated for both cosmetic surgery and repair of outer ear injuries, given its excellent analgesia during and after surgery. The characteristics of this type of block of the pavilion make it ideal for major outpatient surgery and a valid alternative to general anesthesia in adults.
