What is a quincke spinal needle?
Quincke needles (Fig. 2.2) were developed in 1891 and have a sharp cutting bevel that is designed to perform dural punctures. They remain widely used today, although only for interventional pain procedures where dural puncture is not the goal.
What is Postdural puncture headache?
Postdural puncture headache is a potential complication of a lumbar puncture, with symptoms caused by traction on pain-sensitive structures from low cerebrospinal fluid pressure (intracranial hypotension) following a leak of cerebrospinal fluid at the puncture site.
What needle type is best used for reducing the incidence of post lumbar puncture headache?
The committee based its conclusion on 1 prospective randomized trial that demonstrated that the use of an atraumatic Sprotte needle for LP reduces PLPH [38]. The atraumatic needle is easy to use and can significantly reduce the incidence of PLPH.
What is a spinal needle used for?
Spinal needles are used for lumbar puncture for spinal anaesthesia or diagnostic puncture of the spinal canal. Quincke tip with double bevel enables atraumatic puncture of the dura and minimises the risk of post-spinal headache.
When should an intrathecal catheter be removed?
The intrathecal catheter may be left in for up to 24 hours. If the catheter remains in situ it must be capped and clearly labeled to prevent inadvertent injection in the catheter and an order left with specific instructions on when to remove the catheter.
What size needle is used for lumbar puncture?
Some authors have described a successful use of spinal needles as small as 25 gauge when performing a lumbar puncture. The investigators do not believe that the flow-rate difference between 22 and 24 gauge needles is significant enough to justify using the larger needles.
How do you pronounce Tuohy needle?
Tuohy is from the gaelic O’Tuathaigh and can be pronounced Too-ee OR Too-hee. The latter pronunciation is more like the gaelic name would be verbalised.
Who invented the Tuohy needle?
Ralph L. Huber
The hypodermic needle popularized by Edward Tuohy, MD for use in his method of continuous spinal anesthesia has been incorrectly called the “Tuohy needle” since he first popularized it in 1945. It was recently determined that Ralph L. Huber, a Seattle dentist, was the inventor of this widely used needle.
What is a needle tip?
Cutting-tip, or Quincke, needles have sharp, cutting tips, with the hole at the end of the needle. Whitacre and Sprotte needles are two types of pencil point, or noncutting tip needles. They have a closed tip shaped like a pencil, with the hole on the side of the needle near the tip.
