This is a research study to determine if the effects of continuous peripheral nerve blocks are influenced by the distance of insertion past the needle tip of the perineural catheter.
Specific Aim: Research study to determine the relationships between perineural catheter insertion distance and subsequent continuous peripheral nerve block effects.
Hypothesis: during ultrasound-guided perineural catheter placement, inserting the catheter 0-1cm past the needle tip is associated with decreased postoperative pain compared with inserting the catheter 5-6cm past the needle tip.
Allocation: Randomized, Control: Active Control, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Single Blind (Subject), Primary Purpose: Treatment

Use of a flexible subcutaneous catheter improves comfort in patients with DKA compared to the usual treatment with a metal needle.
It is common for people to advise individuals undergoing vaccination to look away from the needle to make them hurt less and be less scary. However, this advice is not backed up by researc...
The purpose of this study is to compare the diagnostic accuracy of a novel endoscopic ultrasound (EUS) biopsy needle to the current standard EUS needle. The investigators hypothesize that...
The primary objective of this proposed prospective randomized, multi-center study is to evaluate the capability of the new 22G SharkCore™ needle to obtain tissue specimens and to compare...
Ultrasound guidance has been established as an effective and safe method during insertion of internal jugular vein catheter.. Needle visualization during advancement toward the vein has a ...
Atrial fibrillation (AF) ablation requires transseptal puncture to access the left atrium. Recently, a radiofrequency (RF) needle was developed. The purpose of this study was to compare the incidence ...
Injection pressure monitoring provides valuable information to prevent intraneural injections and possibly consequent nerve damage during peripheral nerve block. However, the measurement of injection ...
Our aim in this study was to compare the efficiency of 25G versus 22G needles in diagnosing solid pancreatic lesions by EUS-FNA. We performed a systematic review and meta-analysis. Studies were identi...
Robotic-assisted needle steering can enhance the accuracy of needle-based interventions. Application of current needle steering techniques are restricted by the limited deflection curvature of needles...

Usage of a single needle among two or more people for injecting drugs. Needle sharing is a high-risk behavior for contracting infectious disease.
Removal and examination of tissue obtained through a transdermal needle inserted into the specific region, organ, or tissue being analyzed.
Conducting a fine needle biopsy with the aid of ENDOSCOPIC ULTRASONOGRAPHY.
The administration of medication by insertion of a tiny needle or catheter into the spinal sac or epidural cavity.
A type of scanning probe microscopy in which a very sharp conducting needle is swept just a few angstroms above the surface of a sample. The tiny tunneling current that flows between the sample and the needle tip is measured, and from this are produced three-dimensional topographs. Due to the poor electron conductivity of most biological samples, thin metal coatings are deposited on the sample.
Radiology is the branch of medicine that studies imaging of the body; X-ray (basic, angiography, barium swallows), ultrasound, MRI, CT and PET. These imaging techniques can be used to diagnose, but also to treat a range of conditions, by allowing visuali...
Pain is defined by the International Association for the Study of Pain as “an unpleasant sensory and emotional experience associated with actual or potential tissue damage or described in terms of such damage”. Some illnesses can be excruci...
