Ultrasound Localization of Resuscitative Endovascular Balloon Occlusion of the Aorta in a Human Cadaver Model.

Objective: Resuscitative endovascular balloon occlusion of the aorta (REBOA) is a method of gaining proximal control of noncompressible torso hemorrhage (NCTH). Catheter placement is traditionally confirmed with fluoroscopy, but few studies have evaluated whether ultrasound (US) can be used.

Methods: Using a pressurized human cadaver model, a certified REBOA placer was shown one of four randomized cards that instructed them to place the REBOA either correctly or incorrectly in Zone 1 (the distal thoracic aorta extending from the celiac artery to the left subclavian artery) or Zone 3 (in the distal abdominal aorta, from the aortic bifurcation to the lowest renal artery).

Comparison of thromboelastography versus conventional coagulation tests in simulated Crotalus atrox envenomation using human blood.

Introduction: Pit viper bites are a source of significant morbidity and mortality. Pit viper bites can cause venom-induced consumptive coagulopathy (VICC), typically evaluated with laboratory-based conventional coagulation tests (CCTs). However, CCTs require a laboratory and average 1 h to conduct.

Emergency department patient knowledge, opinions, and risk tolerance regarding computed tomography scan radiation.

Background: Computed tomography (CT) scanning use for emergency department (ED) patients has increased exponentially since its inception.

Study Objectives: This study aimed to determine what patients view as the risk of radiation from CT scans, their risk tolerance and preference for alternative testing, and their opinions about informed consent and malpractice regarding CT scans.

Methods: A 25-question survey was administered to a random convenience sample of ED patients aged ≥ 18 years by trained research associates.
