A pericardiocentesis electrode needle.
Pericardial aspiration is more difficult and hazardous than aspiration of other serous cavities. If the aspirating needle is introduced too far, it may injure or tear the myocardium, resulting in hwemopericardium, or induce ventricular fibrillation. The dangers are increased if the effusion is small, or if aspiration is performed as a diagnostic procedure to distinguish an effusion from a cardi...
متن کاملFabrication of ultramicroelectrodes using a "teflon-like" coating material.
A new method was developed for the preparation of ultramicroelectrodes (UMEs). In this method, a photo-curable fluorinated functionalized perfluoropolyether, a liquid v-like polymer at room temperature, is used as the material for the insulation of metal microwires or carbon fibers. The UMEs prepared by this method were usually conical shaped and could be used both in aqueous solutions and with...
متن کاملComparative Evaluation of Periprostatic Nerve Block with and without Intraprostatic Nerve Block in Transrectal Ultrasound-Guided Prostatic Needle Biopsy
PURPOSE Controversy exists over the pain during prostate biopsy. Periprostatic nerve block is a commonly used anaesthetic technique during transrectal ultrasound (TRUS)-guided prostate biopsy. The recent trend toward increasing the number of cores has become popular. This practice further increases the need for a proper anaesthetic application. We compared the efficacy of periprostatic nerve bl...
متن کاملNerve injury by needle nerve perforation in regional anaesthesia.
BACKGROUND In regional anaesthesia, there is a risk of direct nerve injury. The purpose of this study was to determine whether the diameter of the applied needle is associated with the magnitude of nerve injury after needle nerve perforation. METHODS In five anaesthetized pigs, the brachial plexus were exposed bilaterally. Up to eight nerves underwent needle nerve perforation using a 24 G pen...
متن کاملSingle 5 μm diameter needle electrode block modules for unit recordings in vivo
Investigations into mechanisms in various cortical areas can be greatly improved and supported by stable recording of single neuronal activity. In this study, fine silicon wire electrodes (diameter 3 μm, length 160 μm) are fabricated by vapor-liquid-solid (VLS) growth with the aim of stabilizing recording and reducing the invasiveness on the measurement procedure. The electrode is fabricated on...
