Drug-induced aseptic meningitis after an interlaminar lumbar epidural steroid injection.

BACKGROUND: This case report describes a rare instance of drug-induced aseptic meningitis after an interlaminar lumbar epidural steroid injection. CASE PRESENTATION: A 74 year-old female patient presented to the ED post-procedure day three after an L4-L5 interlaminar lumbar epidural steroid injection with fever, nausea, and vomiting. The patient had previously undergone numerous lumbar epidurals without complications and used identical medications, which included 1% lidocaine, iohexol contrast, methylprednisolone (Depo-medrol), and normal saline. Pertinent labs included a WBC of 15,000 cells/µL. Lumbar MRI revealed L4-S1 aseptic arachnoiditis. Two bone scans with Gallium and T-99 confirmed no infectious process. The patient then had a second admission months later with similar presenting symptoms and hospital course after repeating the lumbar epidural steroid injection. Lumbar MRI and CSF studies confirmed aseptic meningitis. CONCLUSION: This patient's repeated admissions from aseptic meningitis were likely caused by irritation of the meningeal layers from a medication used during the procedure.

Retrograde Intubation Over a Flexible Fiber-Optic Bronchoscope.

Traditional retrograde intubation consists of tracheal intubation performed over a guide wire inserted into the trachea inferior to the vocal cords and then passed transorally or transnasally. This intubation technique is reserved for patients with a difficult airway when other methods such as blind nasal intubation or video laryngoscopy fail. A guide wire passed blindly in a retrograde fashion, however, is not without its own constraints. This case report presents the anesthetic management of a 23-year-old Duchenne muscular dystrophy patient with substantial scarring from a previous tracheostomy stoma and limited mouth opening. The patient underwent a retrograde fiber-optic transnasal intubation without the use of a guide wire for a tracheostomy revision procedure, followed by a second tracheostomy revision and retrograde fiber-optic transoral intubation 7.5 months later. This report demonstrates a novel technique for intubating patients with difficult airways. The use of a flexible fiber-optic bronchoscope for a retrograde intubation mitigates complications that can arise using traditional retrograde intubation over a guide wire and increases the likelihood of successful intubation.
