Pneumocephalus, or air in the intracranial space, is most commonly encountered after trauma or surgery. Epidural injections are commonly performed in obstetrics and pain management. Complications are uncommon and include hemorrhage, cerebrospinal fluid leak, and infection. A rare complication is pneumocephalus, described in only a few case reports of epidural anesthesia. ⋯ We describe a 34-year-old woman complaining of a generalized headache 6 days after an unremarkable vaginal delivery that was assisted by an epidural injection. A noncontrast computed tomography scan of the head revealed pneumocephalus secondary to epidural injection. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Pneumocephalus is an uncommon but serious complication of an epidural procedure. Emergency physicians must be aware of this complication entity and maintain this entity in their differential diagnosis given the potential for significant morbidity.

Over a decade ago, the Association of American Medical Colleges called for incorporation of disaster medicine training into the education of medical students in the United States. Despite this recommendation, similar suggestions by other professional organizations, and significant interest from medical students and educators, few medical schools explicitly include robust disaster training in their curricula. ⋯ This intervention represents a low-cost, high-impact mechanism for improving the capacity of an underutilized segment of the health care team to respond to public health emergencies.

Case Reports
Profound Prolonged Bradycardia and Hypotension after Interscalene Brachial Plexus Block with Bupivacaine.
Interscalene brachial plexus blocks have been a routinely performed method of anesthesia for shoulder surgery that decreases the need for general anesthesia, length of stay, and recovery time. We describe a case of bupivacaine toxicity after an interscalene block. ⋯ The patient was a 66-year-old man who presented to our Emergency Department by emergency medical services from an ambulatory surgery center where he had undergone rotator cuff surgery, with bradycardia and hypotension. His symptoms began upon completion of the surgery in which he received interscalene nerve block with bupivacaine and lidocaine. He was given three doses of 0.5 mg atropine and one dose of 1 mg epinephrine for a heart rate of 40 beats/min without any improvement prior to arrival. His bradycardia was refractory to atropine. He was started on a dopamine drip and transferred to the coronary care unit. The timing of his symptoms, minutes after his regional nerve block, and his complete recovery with only supportive care, make the diagnosis of bupivacaine toxicity likely. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Despite the safety profile of local anesthetics, we must be aware of their potential side affects. Whereas most adverse reactions are secondary to misdirection of anesthetic or accidental vascular puncture, local anesthetic systemic toxicity (LAST) is the major cause of significant adverse events with regional anesthesia. As regional anesthesia becomes more common, emergency physicians must be more aware of the potential complications and be able to both diagnose and treat.
