Aim: The aim of this study is an anatomical review regarding the brachial plexus and its relationships with contiguous anatomical structures to better define the Interscalene Brachial Plexus Block Technique already described by Manani (IBPBTM), specifically concerning the point of needle penetration, needle direction and its relationship with OmoClavicular Triangle (OCT) and the inferior belly ...

Purpose: To report our experience with computed tomography (CT)-guided coaxial needle biopsy of intrathoracic lesions by different approaches. Material methods: Medical records of 100 patients who underwent CT-guided biopsy of intrathoracic lesions were evaluated retrospectively. A coaxial needle technique was used in all patients; an 18-gauge needle was used for transsternal penetration, throu...

Corrosion resistance of zircon reinforced alumina refractories has been carried out through static crucible test. The corrosion measurements with percentage, the penetration depth of molten steel and the microstructure of the refractories were evaluated after soaking 150 h at the temperature of 1500˚C. Results showed that the corrosion resistance of alumina increased by adding 20 wt% zirc...

To achieve automatic needle puncturing for automatic blood sampling, we studied peak waveforms of the puncture forces developed during penetration of a blood vessel. Computer simulations of controlled needle puncture were performed using data from experiments on puncturing a rabbit's ear vein. Reproducible results of successive puncturing suggested that this simulation could be applied to the c...

INTRODUCTION The aim was to examine the effect of a sedative or analgesic supplement to periprostatic nerve blockage (PNB) on pain reduction during probe insertion and needle penetration in patients undergoing transrectal ultrasound (TRUS)-guided prostate biopsy. We also investigated the effects of this procedure on the positive response rate in re-biopsy. MATERIAL AND METHODS One hundred TRU...

Normal saline or air is used to identify loss of resistance during identification of the epidural space for combined spinal-epidural analgesia. Following epidural needle placement using air for loss of resistance, up to 80% of parturients move, grimace, vocalise or experience paraesthesia or dysaesthesia during subsequent dural puncture by a spinal needle. We compared the effects of saline vers...

PURPOSE To evaluate needle visibility in ultrasound under contrast mode conditions. MATERIALS AND METHODS Needle visibility was evaluated for bevel, EchoTip ® and shaft of 18G Chiba biopsy needle with a 9 MHz linear probe (GE Logiq E9). Insertion angles varied between 30°(steep) and 90°(parallel to the probe surface). The acoustic output varied from 5-28%. 2 different contrast mode presets wi...
