Pre-Arrival Care of the Out-of-Hospital Cardiac Arrest Victim.

Lay rescuers play a pivotal role in the recognition and initial management of out-of-hospital cardiac arrest. The provision of timely pre-arrival care by lay responders, including cardiopulmonary resuscitation and the use of automated external defibrillator before emergency medical service arrival, is important link in the chain of survival and has been shown to improve outcomes from cardiac arrest. Although physicians are not directly involved in bystander response to cardiac arrest, they play a key role in emphasizing the importance of bystander interventions.

Clinical Effects of Balanced Crystalloids vs Saline in Adults With Diabetic Ketoacidosis: A Subgroup Analysis of Cluster Randomized Clinical Trials.

Importance: Saline (0.9% sodium chloride), the fluid most commonly used to treat diabetic ketoacidosis (DKA), can cause hyperchloremic metabolic acidosis. Balanced crystalloids, an alternative class of fluids for volume expansion, do not cause acidosis and, therefore, may lead to faster resolution of DKA than saline.

A model for rapid emergency department expansion for the COVID-19 pandemic.

COVID-19 has caused global dramatic change in medical practices including the introduction of temporary screening and assessment areas outside the footprint of the main hospital structures. Following the initial surge of patients with novel coronavirus (2019-nCoV) in the United States, our medical center rapidly designed and constructed an alternative assessment and treatment site in a converted parking garage deck for emergency department patients with suspected or confirmed 2019-nCoV. During the first month after opening, 651 patients were treated in this alternative assessment area including 54 patients who tested positive for 2019-nCoV.
