A new technique to assist epidural needle placement: fiberoptic-guided insertion using two wavelengths.
BACKGROUND Up to 10% of epidurals fail due to incorrect catheter placement. We describe a novel optical method to assist epidural catheter insertion in a porcine model. METHODS Optical emissions were tested on ex vivo tissues from porcine paravertebral tissues to identify optical reflective spectra. The wavelengths of 650 and 532 nm differentiated epidural space from the ligamentum flavum. We...
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 کاملAn Alternative Approach to Needle Placement in Cervicothoracic Epidural Injections
The use of fluoroscopy guidance together with the loss of resistance technique during epidural injections has been advocated lately; moreover, epidural injections in the absence of fluoroscopic guidance have a high rate of inaccurate needle-tip placement during the injections. However, the approach to the lower cervical and upper thoracic epidural space may be challenging due to its obscure lat...
متن کاملThe BiP Test: a modified loss of resistance technique for confirming epidural needle placement.
BACKGROUND Correct identification of the epidural space minimizes complications and ensures successful epidural blockade. The loss of resistance technique is the most common technique used for identification of the epidural space. However, sometimes loss of resistance occurs when the needle is not actually in the epidural space. The injection in this instance will result in the medication not b...
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...
