Review Meta Analysis
The prehospital 12-lead electrocardiogram's effect on time to initiation of reperfusion therapy: a systematic review and meta-analysis of existing literature.
The prehospital electrocardiogram (ECG) is becoming the standard of care of suspected cardiac chest pain. We evaluated the evidence regarding the prehospital ECG and sought to quantify the reduction in time to reperfusion therapy attributable to the prehospital ECG. We conducted a systematic review and analyzed studies that were conducted in emergency medical systems relevant to providers in the United States. ⋯ A meta-analysis of these studies revealed a difference of 24.7 (95% confidence interval, 16.7-32.7) minutes. Providers now have a quantified value of the prehospital ECG based on the best published evidence. In addition, this search showed a relatively low quality and quantity of research on the prehospital ECG.

Review Case Reports
Orthopedic pitfalls in the ED: tibial plafond fractures.
Fractures of the tibial plafond, or distal tibial articular surface, are usually associated with a high-force mechanism, which frequently can involve associated injuries and prolonged disability. Because of distracting injury and variations in clinical findings, tibial plafond fractures may be initially missed or misdiagnosed. This review examines the clinical presentation, diagnostic techniques, and management of tibial plafond fractures applicable to the emergency practitioner.

The transthecal digital block is a simple, safe, and effective anesthesia technique that can be used in many digital injuries. It is contraindicated only in cases of infection. The purposes of this article are to (1) discuss the indications for the transthecal digital block, (2) describe the technique, and (3) review the literature. ⋯ It also has virtually no risk of direct mechanical trauma to the neurovascular bundles. This technique has been shown to be exceptionally effective. We encourage emergency physicians to use the transthecal technique when indicated.
