Randomized Controlled Trial Comparative Study Clinical Trial
Randomized double-blind controlled trial comparing room-temperature and heated lidocaine for digital nerve block.
To determine whether warming of lidocaine decreases the pain of its injection during digital nerve block. ⋯ Heating of lidocaine decreases the pain of injection during digital nerve block.

To determine practice patterns regarding administration of the "GI cocktail" (a mixture of liquid antacid, viscous lidocaine, and an anticholinergic) in the emergency department in a single hospital and the responses and final dispositions of patients who received the cocktails. ⋯ Although symptomatic relief after administration of a GI cocktail is often noted, it is difficult to differentiate the effects of the cocktail from those of other coadministered medications such as morphine or nitroglycerin. We urge ED physicians to use the GI cocktail in a rational manner.

Randomized Controlled Trial Comparative Study Clinical Trial
Randomized double-blind comparison of the analgesic efficacy of intramuscular ketorolac and oral indomethacin in the treatment of acute gouty arthritis.
To compare the analgesic effect of IM ketorolac tromethamine with that of oral indomethacin in the treatment of acute gouty arthritis. ⋯ IM ketorolac and oral indomethacin are similar in the relief of the pain of acute gouty arthritis in the ED.

Clinical Trial Controlled Clinical Trial
Effect of adenosine on the management of supraventricular tachycardia by urban paramedics.
To determine the effect of the addition of adenosine, as a standing-order medication, on the prehospital management of supraventricular tachycardia (SVT) in a large urban emergency medical services (EMS) system. ⋯ The introduction of adenosine as a standing-order medication into an urban EMS system increased the proportion of patients who received advanced life support treatment. Paramedics were able to accurately diagnose and begin treatment of SVT with adenosine without direct medical supervision.

Clinical Trial
Measuring the call-receipt-to-defibrillation interval: evaluation of prehospital methods.
Successful resuscitation of cardiac arrest depends partly on the time of first defibrillation. An accurate, practical method of measuring this time has not been devised. We attempted to determine the interval from receipt of a call by emergency medical services personnel to first defibrillation (total defibrillation interval) with synchronized clocks between computer-aided dispatch operations and an event-recording defibrillator. ⋯ The use of synchronized clocks in automated event-recording systems may provide a method of accurately measuring the time elapsed before defibrillation.
