Spinal needle introducer hub detachment

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...

The effect of spinal introducer needle use on postoperative back pain.

Postdural puncture back pain has a reported incidence ranging from 2% to 29% following the administration of a spinal anesthetic. The purpose of this investigation was to compare the back pain and patient satisfaction scores after the administration of a spinal anesthetic with or without the use of an 18-gauge introducer needle. Eighty-four men and women were randomly assigned to either control...

Eldor spinal needle versus Pencan spinal needle.

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...

Loss of resistance to saline reduces responses accompanying spinal needle insertion during institution of 'needle-through-needle' combined spinal-epidural analgesia.

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...
