This paper describes the development and implementation of the INFO (immediate, not for personal assessment, fast facilitated feedback, and opportunity to ask questions) clinical debriefing process. INFO enabled charge nurses to facilitate a group debriefing after critical events across three adult emergency departments (EDs) in Calgary, Alberta. Prior to implementation at our institutions, ED critical event debriefing was a highly variable event. Post-implementation, INFO critical event debriefings have become part of our ED culture, take place regularly in our EDs (254 documented debriefings between March 2016 and September 2017), with recommendations arising from these debriefings being introduced into clinical practice. The INFO clinical debriefing process addresses two significant barriers to regular ED clinical debriefing: a lack of trained facilitators and the focus on physician-led debriefings. Our experience shows that a nurse-facilitated debriefing is feasible, can be successfully implemented in diverse EDs, and can be performed by relatively inexperienced debriefers. A structured approach means that debriefings are more likely to take place and become a routine part of improving team management of high stakes or unexpected clinical events.

This report describes a rare but life-threatening case of a suicide attempt initially considered as intentional overdose at the emergency department. Persistent altered mental status, despite normal toxicology investigations, led the attending team to order a head computed tomography scan, which revealed a bilateral penetrating nail gun injury with a right temporal hematoma for which a decompressive craniectomy was performed. Although voluntary intoxication is the most frequent form of suicide attempt, emergency physicians must be alert and maintain a broad differential diagnosis. Although rare, penetrating head injuries have increased in recent decades. As neurological symptoms can be minimal and penetration wounds small, this type of injury could potentially be overlooked.

Dual sequential external defibrillation (DSED) is the process of near simultaneous discharge of two defibrillators with differing pad placement to terminate refractory arrhythmias. Previously used in the electrophysiology suite, this technique has recently been used in the emergency department and prehospital setting for out-of-hospital cardiac arrest (OHCA). We present a case of successful DSED in the emergency department with neurologically intact survival to hospital discharge after refractory ventricular fibrillation (RVF) and review the putative mechanisms of action of this technique.

Left ventricular outflow tract pseudoaneurysms are a rare but life-threatening disorder, often caused by complications of cardiac surgery or myocardial infarction. We present a case report of a patient with no prior risk factors who presented with a six-month history of progressive exertional dyspnea, bilateral leg swelling and cough. Point-of-care ultrasound revealed an unexpected outpouching of the left ventricle. He was diagnosed with a left ventricular outflow tract pseudoaneurysm and subsequently went into cardiogenic shock secondary to extension of pseudoaneurysm causing extrinsic compression of the coronary arteries. The patient underwent successful emergency surgical repair and made a full recovery.

Editor’s note: CJEM has partnered with a small group of selected journals of international emergency medicine societies to share from each a highlighted research study, as selected monthly by their editors. Our goals are to increase awareness of our readership to research developments in the international emergency medicine literature, promote collaboration among the selected international emergency medicine journals, and support the improvement of emergency medicine world-wide, as described in the WAME statement at http://www.wame.org/about/policy-statements#Promoting%20Global%20Health. Abstracts are reproduced as published in the respective participating journals and are not peer reviewed or edited by CJEM.
