Child maltreatment continues to be one of the most common and most difficult problems seen in the emergency room. An early estimate indicated that up to 10% of children under age 6 seen in emergency departments have some form of nonaccidental injury. Recent data suggest that approximately 1% of the child population are victims of maltreatment each year. ⋯ This article provides a review of the various forms of maltreatment, with emphasis on the key points involved in the history, physical examination, and management. The protocol for evaluating maltreatment from the North Carolina Memorial Hospital is presented. This framework will aid the physician in the crucial first step of identifying maltreatment, which, along with diligent follow-up and the assistance of the available social services, offers the best hope for further prevention.

Thirty-seven critical emergency department patients underwent attempts at external cardiac pacing over an 11-month period. Indications for pacing were asystole in 16, complete heart block (CHB) in 4, sinus bradycardia in 2, nodal bradycardia in 1, atrial fibrillation with bradycardia in 2, electromechanical dissociation in 1, idioventricular rhythm (IVR) in 10, and torsades de pointes in 1. Eight patients were successfully paced with improvement in their condition. ⋯ External cardiac pacemaking appears to be effective in hemodynamically significant bradycardia. It does not appear to be effective in most instances of asystole or IVR resulting from prolonged cardiac arrest. When applied to patients with a responsive myocardium, it may result in significant hemodynamic improvement and may be lifesaving.

Case Reports
Fatal intracranial hemorrhage associated with phenylpropanolamine, pentazocine, and tripelennamine overdose.
Hemorrhagic cerebrovascular accident is an uncommon but serious complication of drug overdose. A case of fatal intracranial hemorrhage following overdose with phenylpropanolamine, pentazocine, and tripelennamine is presented. The pharmacology, pathophysiology, clinical presentation, and management of poisoning by these agents are discussed.

Clinical Trial Controlled Clinical Trial
Lidocaine reduces intravenous diazepam pain.
We studied 41 consecutive patients receiving intravenous (IV) diazepam in the preoperative holding area to evaluate whether low-dose IV lidocaine could ameliorate pain of the diazepam injection. In a double-blind trial we found 1 cc of 1% lidocaine effective versus placebo at lowering the incidence of pain from 80% to 5% (P less than .001) and recommend its routine use as an antecedent to IV diazepam.

Comparative Study
Pressurization of i.v. bags: a new configuration and evaluation for use.
External pressure devices are often utilized to increase the flow rates of IV fluids in exsanguinating patients. However, increasing the flow rate by this method also increases the rate at which IV bags need changing. Time is lost and valuable personnel are preoccupied in maintaining the numerous hand-pumped external pressure devices and IV bags. ⋯ A new multiunit configuration (Infusor-Rack) for the pneumatic device is also described. We found a significant decrease in IV bag take-down/setup time with the new pneumatic pressure device. This system is faster, more reliable, and easier to use than the standard hand-pumped pressure bag and should be viewed as a practical improvement in the fluid delivery system.
