Emergency Department (ED) leaders are increasingly confronted with large amounts of data with the potential to inform and guide operational decisions. Routine use of advanced analytic methods may provide additional insights. ⋯ In this study regarding the use of advanced analytics in daily ED operations, time series analysis provided multiple useful insights into boarding and its impact on performance metrics.

Carbon monoxide (CO) is a leading cause of morbidity and mortality. Treatment focuses on the rapid elimination of CO and management of hypoxia. Oxygen is the cornerstone of therapy, and usually applied via a reservoir face mask. ⋯ One patient was treated by non-invasive CPAP-ventilation support with a FiO2 of 100%, whereas the other was treated by conventional oxygen inhalation. In the patient treated by CPAP, COHb-levels fell quickly to 6% within one hour, and reached 3% after 90 min, whereas it took six hours to reach the same levels in the patient with conventional treatment. This vividly illustrates the potential of CPAP therapy as an alternative to conventional oxygen inhalation in the treatment of CO poisoning.

We had previously experienced a case involving prolonged cardiopulmonary resuscitation (CPR) on Mt. Fuji (3776 m), demanding strenuous work by the rescuers. The objective of this study was to compare the effect of compression-only and conventional CPR on oxygen saturation of rescuers in a hypoxemic environment. ⋯ Prolonged CPR at high altitude exerts a significant physical effect upon the condition of rescuers. Compression-only CPR at high altitude may deteriorate rescuer oxygenation, whereas CPR with breaths might ameliorate such deterioration.

Thrombus burden in pulmonary embolism (PE) is associated with higher D-Dimer-levels and poorer prognosis. We aimed to investigate i) the influence of right ventricular dysfunction (RVD), deep venous thrombosis (DVT), and high-risk PE-status on D-Dimer-levels and ii) effectiveness of D-Dimer to predict RVD in normotensive PE patients. ⋯ Thrombus burden in PE is related to elevated D-Dimer levels, and D-Dimer values >1.18 mg/l were predictive for RVD in normotensive patients. D-Dimer levels were influenced by DVT, but not by cancer, pneumonia, age, or renal impairment.

Loperamide abuse cardiotoxicity. Should loperamide still be an over the counter medication?
Loperamide is an over-the-counter anti-diarrheal medication that is inexpensive, easily accessible, and widely used. It is generally thought to be safe and effective without the potential for abuse. However, recent discovery of its ability to treat opioid withdrawal symptoms at high doses has led to not only its abuse, but also the need to recognize its cardiotoxicity due to the ability to prolong the QTc interval. ⋯ Electrocardiogram showed prolongation of the QTc and the patient later admitted to ingestion of 70 loperamide pills daily for the past year in order to alleviate her opioid withdrawal symptoms. Due to increased loperamide abuse and toxicity displayed within the last several years, public and health provider awareness should be optimized to fully understand its lethality, and stricter regulations on its availability to the general population should be considered. Even in asymptomatic patients with ECG abnormalities, emergency medicine physicians should admit them for further monitoring and aggressive medical therapy.
