Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
Comparison of midazolam and diazepam for conscious sedation in the emergency department.
To compare the efficacy of diazepam and midazolam when used for conscious sedation in emergency department patients. ⋯ Diazepam and midazolam are both effective for conscious sedation in ED patients. Midazolam causes less pain on injection, a significantly greater degree of early sedation, and a more rapid return to baseline function.

Randomized Controlled Trial Comparative Study Clinical Trial
Comparison of intramuscular meperidine and promethazine with and without chlorpromazine: a randomized, prospective, double-blind trial.
To compare the effectiveness of intramuscular meperidine (2 mg/kg) and promethazine (1 mg/kg) with chlorpromazine (MPC) or without chlorpromazine (MP) (1 mg/kg) for sedation of children undergoing emergency department procedures. ⋯ Elimination of chlorpromazine from the IM combination of meperidine and promethazine for pediatric sedation during ED procedures results in a significant reduction in efficacy.

Review Randomized Controlled Trial Clinical Trial
The use of antiarrhythmics in advanced cardiac life support.
Antiarrhythmic agents have been used to treat malignant ventricular arrhythmias in the setting of acute myocardial ischemia with proven efficacy for many years. Thus, it has been presumed that these agents would be efficacious for the treatment of cardiac arrest. Unfortunately, hard data supporting this contention are unavailable to date. ⋯ However, given the importance of magnesium and potassium levels in the genesis of malignant arrhythmias, their levels in plasma should be assessed, and abnormalities should be promptly corrected. The potential uses of antiarrhythmic agents during advanced cardiac life support span a remarkably diverse number of applications. For the purpose of this review, only the use of these agents during CPR and during the early hours of acute or suspected acute myocardial infarction will be considered.

Randomized Controlled Trial Clinical Trial
Dexamethasone as adjuvant therapy for severe acute pharyngitis.
To determine the efficacy of dexamethasone as adjuvant therapy to improve pain relief in patients with severe, acute exudative pharyngitis. ⋯ In patients with severe, acute exudative pharyngitis, single-injection dexamethasone adjuvant compared with placebo resulted in statistically and clinically significant improvement, as evidenced by more rapid onset and greater degree of pain relief.

At present, fewer than 10% of cardiopulmonary resuscitation (CPR) attempts prehospital or in hospitals outside special care units result in survival without brain damage. Minimizing response times and optimizing CPR performance would improve results. A breakthrough, however, can be expected to occur only when cerebral resuscitation research has achieved consistent conscious survival after normothermic cardiac arrest (no flow) times of not only five minutes but up to ten minutes. ⋯ More than ten drug treatments evaluated have not reproducibly mitigated brain damage in such animal models. Controlled clinical trials of novel CPCR treatments reveal feasibility and side effects but, in the absence of a breakthrough effect, may not discriminate between a treatment's ability to mitigate brain damage in selected cases and the absence of any treatment effect. More intensified, coordinated, multicenter cerebral resuscitation research is justified.
