Although electrolyte abnormalities are related to worse clinical outcomes in patients with acute myocardial infarction (AMI), little is known about the association between admission serum magnesium level and adverse events in AMI patients complicated by out-of-hospital cardiac arrest presenting with malignant ventricular arrhythmias (OHCA-MVA). We investigated the prognostic value of serum magnesium level on admission in these patients. ⋯ In reperfused AMI patients complicated by OHCA-MVA, admission serum magnesium level might be a potential surrogate marker for predicting in-hospital death.

Randomized Controlled Trial
Is ketamine sedation without local anesthesia sufficient for pediatric laceration repair? A double-blind randomized clinical trial.
The objective of this study was to evaluate whether sedation with ketamine without local anesthesia was sufficient in children undergoing primary repair. ⋯ Sedating with ketamine for primary wound repair, there was no difference in pain and sedation scales between the patients treated with or without lidocaine local anesthesia, and local anesthesia was not needed.

The application of appropriate personal protective equipment for respiratory protection to health care workers is a cornerstone for providing safe healthcare in emergency departments. We investigated the protective effect and usefulness of loose-fitting powered air-purifying respirators (PAPRs) during chest compression. ⋯ The loose-fitting PAPRs provided sufficient respiratory protection without disturbances during chest compression.

Randomized Controlled Trial
Efficacy of ketamine for initial control of acute agitation in the emergency department: A randomized study.
Clinicians often encounter agitated patients, and current treatment options include benzodiazepines and antipsychotics. Ketamine rapidly induces dissociation, maintains cardiovascular stability, spontaneous respirations, and airway reflexes. There are no prospective, randomized studies comparing ketamine to other agents in the initial management of acute agitation in the Emergency Department (ED). ⋯ In patients with combative agitation, ketamine was significantly more effective than haloperidol/lorazepam for initial control of acute agitation, and was not associated with any significant adverse effects.

The objective of this study was to determine if performing a methicillin-resistant Staphylococcus aureus (MRSA) nasal screen in the emergency department (ED) decreased general medicine patient exposure to anti-MRSA antibiotics for pneumonia. ⋯ Performing a MRSA nares screen in the ED for patients diagnosed with pneumonia, initiated on anti-MRSA antibiotics, and admitted to a general medicine floor did not decrease duration of anti-MRSA antibiotics. At this time, ED providers do not need to consider a MRSA nasal screen in the ED for patients being admitted to general medicine, although larger studies could be considered.
