IMPLICATIONS In this article we discuss the development of epidural needles and the historical factors leading to their invention. The most popular needles are described and their inventors acknowledged.
متن کاملEpidural catheter penetration of human dural tissue: in vitro investigation.
BACKGROUND Factors contributing to subarachnoid catheter passage after epidural placement are not well understood. This study explored mechanisms that might explain its occurrence. METHODS Human cadaveric dura was mounted on a model and pressurized to physiologic levels. In a standardized fashion, a 20-gauge Portex three-port, closed end (nonflexible) tip catheter was passed through an epidur...
متن کاملVertical Small-Needle Caudal Epidural Injection Technique
BACKGROUND Anecdotal evidence suggests that a vertical small-needle injection method enters the caudal epidural space with comparable efficacy to cephalad-directed methods, with less intravascular injection. OBJECTIVES Assess the success rate of vertical caudal epidural injection using epidurography and the frequency of intravascular injection using a vertical small-needle approach. PATIENT...
متن کاملUltrasound guidance in caudal epidural needle placement.
BACKGROUND This study was conducted to investigate the feasibility of using ultrasound as an image tool to locate the sacral hiatus accurately for caudal epidural injections. METHODS Between August 2002 and July 2003, 70 patients (39 male and 31 female patients) with low back pain and sciatica were studied. Soft tissue ultrasonography was performed to locate the sacral hiatus. A 21-gauge caud...
متن کاملvertical small-needle caudal epidural injection technique
results first needle placement without imaging resulted in blood return in 1/199 participants and positive epidurography in 179/199 (90%). minimal needle repositioning resulted in a positive epidurogram in the remaining 19 attempts. no intravascular injection patterns were observed. conclusions this compares favorably to published success rates of fluoroscopically-guided technique and was well ...
