BACKGROUND The precise localization of painful structures in the spine of patients with low back pain and/or pain radiating (LBP/RP) to the lower extremities is important for targeted therapeutic intervention. The aim of the study reported here was to determine and compare the spinal segment(s) where pain was elicited via endoscopic evaluation vs. the(More)
The effect of ketamine on myocardial contractile force was examined in rabbit papillary muscles in order to determine the underlying mechanism of action of the anesthetic. Ketamine HCl (20 and 40 mg/L) inhibited rested-state contractions that are dependent on the transsarcolemmal influx of Ca2+ for activation and reduced the upstroke velocity of the slow(More)
Visceral pelvic pain is a common problem with variable etiology. The sympathetic nervous system plays an important role in the transmission of visceral pain independent of its etiology. Five major pathways by which pelvic pain is transmitted can be identified. One of them, the superior hypogastric plexus, an extension of the preaortic plexus, is easily(More)
BACKGROUND Epidural fibrosis has been implicated in the etiology of persistent pain after back surgery (Failed Back Surgery Syndrome [FBSS]). Using spinal endoscopy to view the lumbosacral epidural cavity, the incidence, severity, and appearance of epidural fibrosis was evaluated in patients with FBSS. METHODS A prospective cohort observational study(More)
PURPOSE The purpose of this study is to examine the relationship between the occurrence of a difficult intubation and (1) the use of neuromuscular blocking agents (NMB) and (2) the presence of airway injuries. It is a retrospective analysis of data from a trauma registry. MATERIALS AND METHODS Registry records of patients (n = 160) who required emergent(More)
PURPOSE This review on ultrarapid detoxification examines the pharmacology, techniques, and efficacy of this potentially promising technique and contrasts it with conventional treatment modalities. SOURCE The information found here is derived from experiences at the Texas Tech University, government reports, and peer reviewed journals. PRINCIPLE(More)
OBJECTIVE The aim of this study was to evaluate the significance of diagnostic markers obtained through epiduroscopy by evaluating the accuracy of outcome prediction after treatment of epidural pathology using epiduroscopy. DESIGN A prospective observational study of 139 patients was performed. Patients with chronic low back and leg pain were included. Of(More)
INTRAVASCULAR injection, either intraarterial or intravenous, is an undesired event that can occur during attempted epidural injections through needles and catheters. When it occurs, it is attributed to entry of the needle or catheter into a blood vessel. There are no reports in the literature of this being observed during epiduroscopy. We report two cases(More)
There exists substantial evidence that a peridural membrane (PM) is present in the spinal canal of humans and, like the pleura and peritoneum, has one or more physiologic functions. Innervation of the PM suggests that it may become a source of pain if injured. Although debated, the physiology of this structure has important implications with respect to(More)
