Cervicofacial subcutaneous emphysema and pneumomediastinum after retinal detachment surgery: just another monitored anesthesia eye case.

Repair of a retinal detachment was performed during a retrobulbar block with monitored anesthesia care and intravenous conscious sedation. Following the procedure and after removal of the sterile drapes, the patient exhibited significant swelling of the bilateral orbits, face, neck, and chest. Subcutaneous emphysema and pneumomediastinum were confirmed on postoperative chest radiographs and computed tomographic scans.

Ultrasonographic evaluation of neck hematoma and block salvage after failed neurostimulation-guided interscalene block.

Ultrasound-guided regional anesthetic techniques have shown some advantages over conventional paresthesia and neurostimulation techniques. We report the case of a neurostimulation-guided continuous interscalene block that would have ended in complication were it not for experience with ultrasound-guided regional anesthesia. Familiarity with ultrasound-guided block techniques permitted assessment of a neck hematoma during interscalene block and ultimately allowed successful peripheral nerve block.

A systematic review of therapeutic facet joint interventions in chronic spinal pain.

Background: Facet joints are considered to be a common source of chronic spinal pain. Facet joint interventions, including intraarticular injections, medial branch nerve blocks, and neurotomy (radiofrequency and cryoneurolysis) are used to manage chronic facet-mediated spinal pain. A systematic review of therapeutic facet interventions published in January 2005, concluded that facet interventions were variably effective for short-term and long-term relief of facet joint pain.

Sacroiliac joint interventions: a systematic review.

Background: The sacroiliac joint is a diarthrodial synovial joint with abundant innervation and capability of being a source of low back pain and referred pain in the lower extremity. There are no definite historical, physical, or radiological features to provide definite diagnosis of sacroiliac joint pain, although many authors have advocated provocational maneuvers to suggest sacroiliac joint as a pain generator. An accurate diagnosis is made by controlled sacroiliac joint diagnostic blocks.

The pharmacology of sedation.

Sedation is commonly provided for patients undergoing interventional pain management procedures. Although many pain management interventionalists have trained in anesthesiology, the use of sedatives, analgesics and hypnotics, as well as monitoring techniques, may vary considerably between practices. This review provides an update on recent advances in the pharmacology of drugs commonly used for sedation, anxiolysis and analgesia.

Therapeutic facet joint interventions in chronic spinal pain: a systematic review of effectiveness and complications.

Background: Facet joint interventions are used frequently for managing chronic spinal pain. Evidence continues to accumulate supporting the clinical effectiveness of these procedures and defining potential complications.

Objective: To evaluate the effectiveness of three types of facet joint interventions (facet joint injections, medial branch blocks and facet joint neurotomy) in managing spinal pain.
