In this study we present the efficacy of aspiration of disc material employing the Stryker Disc Dekompressor during percutaneous microdiscectomy for the treatment of chronic spinal and radicular pain due to contained lumber disc herniation and compare the short-term outcome in such patients with those who received lumber epidural injection. A total of 50 patients with chronic lumber discogenic ...

Systemic neurotoxicity due to excessive cerebral local anesthetic blood levels is one of the most severe and most frequent adverse outcome of local anesthetic use. Toxic levels are most often produced by unintentional intravenous or intraarterial injection(1,2). Toxicity can also result from the rapid absorption of drug following perineural injection. Peak blood levels are usually obtained acco...

The studybySoares et al. 1 published in this edition of the Brazilian Journal of Anesthesiology has aroused old questions about anesthetic techniques for eye surgery: retrobulbar, peribulbar, extraconal, periconal and subtenonian Anesthetic techniques aim at depositing local anesthetics in a given point as from which spread may reach ciliary nerves responsible for eye sensitivity, ciliary gangl...

PURPOSE Barrier properties of the skin and physicochemical properties of drugs are the main factors for the delivery of local anesthetic molecules. The present work evaluates the anesthetic efficacy of drug-loaded nanocarrier (NC) systems for the delivery of local anesthetic drug, ropivacaine (RVC). METHODS In this study, transcriptional transactivator peptide (TAT)-decorated RVC-loaded NCs (...

Introduction: Nasal septal hematoma (NSH) is a complication of nasal trauma, which its emergency treatment drainage hematoma. Delayed may result in necrosis the cartilage and saddle nose deformity. Case Presentation: Here, we reported 15-year-old girl presented with NSH associated dental local anesthetic injection, led to septum necrosis. Conclusions: Computerized tomography (CT) scanning was p...

The current recommendations regarding maximum doses of local anesthetics presented in textbooks, or by the responsible pharmaceutical companies, are not evidence based (ie, determined by randomized and controlled studies). Rather, decisions on recommending certain maximum local anesthetic doses have been made in part by extrapolations from animal experiments, clinical experiences from the use o...

background: because nerve stimulators are not always available for brachial plexus block, fmding the right injection spot for nerve blocks is important. in this study we used physical examination to determine the appropriate spot for injection. methods: all patients who were candidates for upper extremity surgery and were either in class asa i or asa ii, were selected. paresthesia was elicited ...

THE relatively recent technological advances and clinical research are continuously facilitating the metamorphosis of ultrasound-guided regional anesthesia from an experimental technique into a standard procedure in clinical care. The intense enthusiasm from its most vocal proponents led to almost religious belief that the ability to continuously monitor needle placement and administration of l...

STUDY DESIGN The authors developed a diagnostic double-blindfolded survey using placebo-controlled local anesthetic blocks. OBJECTIVE To determine the prevalence of cervical zygapophysial joint pain among patients with chronic neck pain (more than 3 months' duration) after whiplash injury. SUMMARY OF BACKGROUND DATA The prevalence of cervical zygapophysial joint pain after whiplash has been...
