A paucity of literature exists dedicated to the identification of anoxic brain injury in patients that survive non-fatal intimate partner strangulation (NF-IPS). While some individuals report experiencing symptoms of brain hypoxia followed by a loss of consciousness, other individuals report symptoms of brain hypoxia prior to amnesia, rendering some unable to recall loss of consciousness (LOC). ⋯ Within our sample, 49% of patients with amnesia did not recall losing consciousness, demonstrating that LOC is an imperfect measure of anoxia for patients following NF-IPS. Healthcare providers examining NF-IPS patients should inquire about additional symptoms of hypoxia and amnesia, which can be captured on the SHASTA tool.

Preoxygenation is critical to safe performance of rapid sequence intubation (RSI). The use of positive-pressure ventilation (PPV) has been advocated during preoxygenation but may increase the risk of aspiration. ⋯ The use of PPV during preoxygenation prior to RSI appears beneficial for hypoxemic but not normoxemic patients due to lower intubation success and increased aspiration risk with PPV. This data supports selective use of PPV prior to the initial intubation attempt in patients undergoing RSI.

Safety of Diltiazem for Acute Management of Atrial Fibrillation (AF) in Patients with Heart Failure and Reduced Ejection Fraction in the Emergency Department.
Diltiazem is an effective rate control agent for atrial fibrillation with rapid ventricular rate (AF RVR). However, its negative inotropic effects may increase the risk for worsening heart failure in patients with a reduced ejection fraction (EF). ⋯ The development of worsening heart failure is multifactorial and may include the use of diltiazem in critically ill patients requiring hospital admission.
