Epidural or intradural puncture with inappropriately stiffened or improperly placed needles can carry cells or fragments of epithelial tissue into the epidural or intradural space. These skin fragments feed by imbibition, possibly leading to the development of epidermoid cysts. We aimed to study the ability of today's needles to transport cells or epithelial fragments. ⋯ There was a significant difference between the amount of tissue transported by the Touhy needles in comparison with the Quincke (p < 0.01) and Sprotte (p < 0.05) needles. Needles from some manufacturers transport epithelial fragments during lumbar puncture. We believe that better quality control during manufacture of epidural and intradural needles can help to eradicate the rare neurological complications derived from the removal of epithelial cells and their subsequent deposit inside the spinal channel.

Randomized Controlled Trial Comparative Study Clinical Trial[Comparison of changes in plasma concentrations of ACTH and beta-endorphin in cholecystectomy under general anesthesia and general plus epidural anesthesia].
To study neuroendocrine response during cholecystectomy under general anesthesia with fentanyl and under general anesthesia with nitrous oxide plus thoracic epidural block, by determining plasma levels of ACTH and beta-endorphin. ⋯ General anesthesia with fentanyl at the dose used in this study was more effective that combined anesthesia in mitigating the release of ACTH and beta-endorphin during cholecystectomy.

Randomized Controlled Trial Clinical Trial[Efficacy of the EMLA cream in the reduction of pain caused by venipuncture in children premedicated with oral midazolam].
EMLA cream, a lidocaine-prilocaine mixture, penetrates skin easily. Our aim was to compare EMLA and placebo to assess the efficacy of EMLA in decreasing the pain of venipuncture in children premedicated with oral midazolam 0.5 mg/kg. ⋯ EMLA cream decreases the pain of hand venipuncture in children premedicated with oral midazolam.
