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

Atrial fibrillation is the most common arrhythmia but can be treated by a catheter procedure where specialized wires (so-called catheters) are inserted in the left upper heart chamber. Thi...
Epidural waveform analysis (EWA) provides a simple confirmatory adjunct for loss-of-resistance (LOR): when the needle/catheter tip is correctly positioned inside the epidural space, pressu...
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...
Fine needle aspiration (FNA) cytology has been the preferred technique for procuring tissue at endoscopic ultrasound (EUS) procedures for the past 25 years. To overcome some of the limitations of FNA ...
Injection pressure monitoring provides valuable information to prevent intraneural injections and possibly consequent nerve damage during peripheral nerve block. However, the measurement of injection ...
Two patients were referred to a maxillofacial surgeon in connection with the occurrence of needle breakage during local anaesthesia. In the first case, of a 67-year-old woman, it concerned a needle br...
Dural puncture, paraesthesia and vascular puncture are the most common complications of epidural catheter insertion. Their association with variation in midline needle insertion depth is unknown.
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.

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...
Surgery is a technology consisting of a physical intervention on tissues. All forms of surgery are considered invasive procedures; so-called "noninvasive surgery" usually refers to an excision that does not penetrate the structure being exci...
