TAP block, needle through introducer approach

Radiofrequency cauterization with biopsy introducer needle.

PURPOSE The principal risks of needle biopsy are hemorrhage and implantation of tumor cells in the needle tract. This study compared hemorrhage after liver and kidney biopsy with and without radiofrequency (RF) ablation of the needle tract. MATERIALS AND METHODS Biopsies of liver and kidney were performed in swine through introducer needles modified to allow RF ablation with the distal 2 cm o...

No needle to fear: An approach to needle phobic patients

   18F-FDG is the most commonly used radioisotope in PET scanning and is administered intravenously. When patients cannot cannulated, there are limited options available for functional tumour assessment. A fifty year old male presented for investigation of a suspected lung carcinoma identified during investigation of pneumonia. The patient had a severe needle phobia, intellectual dis...

Inadvertent Dural Puncture during Caudal Approach by the Introducer Needle for Epidural Adhesiolysis Caused by Anatomical Variation

There have been reports of abnormalities in the lumbosacral region involving a lower-than-normal termination of the dural sac, which is caused by disease or anatomical variation. Inadvertent dural puncture or other unexpected complications can occur during caudal epidural block or adhesiolysis in patients with these variations, but only a small number of case reports have described this issue. ...

Comparison of Needle Insertion and Guidewire Placement Techniques During Internal Jugular Vein Catheterization: The Thin-Wall Introducer Needle Technique Versus the Cannula-Over-Needle Technique.

OBJECTIVES For needle insertion and guidewire placement during central venous catheterization, a thin-wall introducer needle technique and a cannula-over-needle technique have been used. This study compared these two techniques regarding the success rates and complications during internal jugular vein catheterization. DESIGN Prospective, randomized, controlled study. SETTING A university-af...
