Randomized Controlled Trial Clinical TrialCPR before defibrillation in out-of-hospital cardiac arrest: a randomized trial.
Current resuscitation guidelines recommend that defibrillation be undertaken as soon as possible in patients suffering a cardiac arrest where the cardiac rhythm is either ventricular fibrillation (VF) or ventricular tachycardia (VT). Evidence from animal and clinical studies suggests that outcomes may be improved if a period of cardiopulmonary resuscitation (CPR) is given prior to defibrillation. The objective of this study was to determine if 90 seconds of CPR before defibrillation improved survival. ⋯ Ninety seconds of CPR before defibrillation does not improve overall survival in patients suffering VF/VT cardiac arrests. Further studies to evaluate various aspects of this treatment strategy are required as published outcomes to date are inconclusive.

Prospective analysis of the effect of physician experience with the FAST examination in reducing the use of CT scans.
The objective of this study was to examine the effect of ultrasound experience level on emergency physicians' Focused Assessment with Sonography for Trauma (FAST) exam accuracy and emergency physicians' confidence in using FAST findings to assist in managing patients with blunt trauma. ⋯ FAST accuracy was greatest among more experienced emergency physicians. A normal FAST exam assisted more experienced emergency physicians with the perceived need to order significantly fewer CT scans than less experienced emergency physicians.

Tramadol is a synthetic analgesic new to the Australasian market where its use is rapidly increasing. It is used extensively overseas, particularly in Europe where it has been popular since its introduction in Germany in the late 1970s. Tramadol has a dual mechanism of action: weak mu opioid receptor agonist and a reuptake inhibitor of serotonin and noradrenaline. ⋯ Its use is advocated in a variety of acute and chronic pain states as well as some non-analgesic applications. The use of tramadol in an emergency setting is not well studied, with most published trials assessing its efficacy and tolerability in postoperative or dental models. This literature review concludes that tramadol does not offer any particular benefits over existing analgesics for the majority of emergency pain relief situations.
