Implementation of Extracorporeal CPR Programs for Out-of-Hospital Cardiac Arrest: Another Tale of Two County Hospitals.

Extracorporeal cardiopulmonary resuscitation (ECPR) is a form of intensive life support that has seen increasing use globally to improve outcomes for patients who experience out-of-hospital cardiac arrest (OHCA). Hospitals with advanced critical care capabilities may be interested in launching an ECPR program to offer this support to the patients they serve; however, to do so, they must first consider the significant investment of resources necessary to start and sustain the program. The existing literature describes many single-center ECPR programs and often focuses on inpatient care and patient outcomes in hospitals with cardiac surgery capabilities. However, building a successful ECPR program and using this technology to support an individual patient experiencing refractory cardiac arrest secondary to a shockable rhythm depends on efficient out-of-hospital and emergency department (ED) management. This article describes the process of implementing 2 intensivist-led ECPR programs with limited cardiac surgery capability. We focus on emergency medical services and ED clinician roles in identifying patients, mobilizing resources, initiation and management of veno-arterial extracorporeal membrane oxygenation (VA-ECMO) in the ED, and ongoing efforts to improve ECPR program quality. Each center experienced a significant learning curve to reach goals of arrest-to-flow times of cannulation for ECPR. Building consensus from multidisciplinary stakeholders, including out-of-hospital stakeholders; establishing shared expectations of ECPR outcomes; and ensuring adequate resource support for ECPR activation were all key lessons in improving our ECPR programs.

Implementation of Extracorporeal Membrane Oxygenation Without On-Site Cardiac Surgery or Perfusion Support: A Tale of Two County Hospitals.

Patients with refractory respiratory and cardiac failure may present to noncardiac surgery centers. Prior studies have demonstrated that acute care surgeons, intensivists, and emergency medicine physicians can safely cannulate and manage patients receiving extracorporeal membrane oxygenation (ECMO). Harborview Medical Center (Harborview) and Hennepin County Medical Center (Hennepin) are both urban, county-owned, level 1 trauma centers that implemented ECMO without direct, on-site cardiac surgery or perfusion support. Both centers 1) use an ECMO specialist model staffed by specially trained nurses and respiratory therapists and 2) developed comparable training curricula for ECMO specialists, intensivists, surgeons, and trainees. Each program began with venovenous ECMO to provide support for refractory hypoxemic respiratory failure and subsequently expanded to venoarterial ECMO support. The coronavirus disease 2019 (COVID-19) pandemic created an impetus for restructuring, with each program creating a consulting service to facilitate ECMO delivery across multiple intensive care units (ICUs) and to promote fellow and resident training and experience. Both Harborview and Hennepin, urban county hospitals 1,700 miles apart in the United States, independently implemented and operate adult ECMO programs without involvement from cardiovascular surgery or perfusion services. This experience further supports the role of ECMO specialists in the delivery of extracorporeal life support.

Emergency Department Management of Out-of-Hospital Laryngeal Tubes.

STUDY OBJECTIVE: Laryngeal tubes are commonly used by emergency medical services (EMS) personnel for out-of-hospital advanced airway management. The emergency department (ED) management of EMS-placed laryngeal tubes is unknown. We seek to describe ED airway management techniques, success, and complications of patients receiving EMS laryngeal tubes. METHODS: Using a keyword text search of ED notes, we identified patients who arrived at our ED with a laryngeal tube from 2010 through 2017. We performed structured chart and video reviews for all eligible patients. In our ED, emergency physicians perform all airway management, and there is no protocol dictating airway management for patients arriving with a laryngeal tube. Using descriptive methods, we report the techniques, success, and complications of ED airway management. RESULTS: We analyzed data on 647 patients receiving out-of-hospital laryngeal tubes, including 472 (73%) with cardiac arrest from medical causes, 75 (21%) with cardiac arrest from trauma, and 100 (15%) with other conditions. For 580 patients (89%), emergency physicians exchanged the laryngeal tube for a definitive airway in the ED. Of the 67 patients not intubated in the ED, 66 died in the ED without further airway management. Of the 580 patients intubated in the ED, orotracheal intubation was the first method attempted for 578 (>99%) and was successful on the first attempt for 515 of 578 (89%). Macintosh video laryngoscopy (88% of initial attempts) and a bougie (68% of initial attempts) were commonly used adjuncts. For 345 of 578 patients (60%), the laryngeal tube was removed before intubation attempts. For 112 of 578 patients (19%), the first intubation attempt occurred with the deflated laryngeal tube left in place. Three patients (<1%) required a surgical airway. CONCLUSION: In this cohort, emergency physicians successfully exchanged an out-of-hospital laryngeal tube for an endotracheal tube, using commonly available airway management techniques. ED clinicians should be familiar with techniques for exchanging out-of-hospital extraglottic airways for an endotracheal tube.
