Randomized Controlled Trial Comparative Study Clinical Trial[Axillary brachial plexus anesthesia. How many nerve stimulation responses do we look for?].
To determine whether axillary block with nerve stimulation involving the location of four motor responses is more effective than other techniques using fewer locations, without increasing patient discomfort or the rate of complications. ⋯ Locating 4 responses gives the greatest degree of assurance of obtaining full sensory block without increasing patient discomfort or rate of complications.

Randomized Controlled Trial Comparative Study Clinical Trial[The effect of propofol vs desflurane on recovery from anesthesia with remifentanil in outpatient surgery].
To compare the effect on parameters of postanesthetic recovery of propofol and desflurane administered with high doses of remifentanil for major outpatient surgery. ⋯ During anesthesia with remifentanil, the administration of desflurane is associated with better psychomotor recovery parameters than is propofol, but the rate of nausea and vomiting is higher with desflurane.

[Preoperative testing routines for healthy, asymptomatic patients in the Canary Islands (Spain)].
To analyze patterns of routine testing before elective/scheduled surgery in healthy/asymptomatic patients classified as ASA I or II according to the American Society of Anesthesiologists. ⋯ Hospitals and individual anesthesiologists differ considerably in how they request preoperative tests. The variations can not be explained solely by differing patient needs given that respondents were contemplating only healthy/asymptomatic individuals undergoing relatively simple procedures.

Case Reports[Cauda equina syndrome after intradural anesthesia with bupivacaine].
A 70-year-old man developed pain and functional weakness in the lower limbs with dysesthesia and urinary retention after subarachnoid anesthesia with 0.5% hyperbaric bupivacaine. Neurological and electrophysiological tests and follow-up, as well as diagnostic images (CAT and MR), ruled out spinal cord lesions. ⋯ Associated with use of microcatheters for continuous subarachnoid anesthesia and 5% hyperbaric lidocaine, cauda equina syndrome is rare after a single injection of bupivacaine. Although the pathogenesis of cauda equina syndrome is poorly understood, there is agreement on the neurotoxicity of local anesthetics, particularly of 5% hyperbaric lidocaine.
