Neurologic outcomes of prehospital mechanical chest compression device use during transportation of out-of-hospital cardiac arrest patients: a multicenter observational study.

Objective: High-quality cardiopulmonary resuscitation with chest compression is important for good neurologic outcomes during out-of-hospital cardiac arrest (OHCA). Several types of mechanical chest compression devices have recently been implemented in Korean emergency medical services. This study aimed to identify the effect of prehospital mechanical chest compression device use on the outcomes of OHCA patients.

Prolonged oral sildenafil use-induced Mondor disease: a case report.

Penile Mondor disease (MD) is a palpable, painful, subcutaneous induration caused by superficial dorsal penile vein thrombosis. We report a case of penile MD that was suspected to be related to prolonged oral sildenafil use. A 46-year-old man visited our emergency department with sustained penile pain and swelling that began 7 hours after sexual intercourse.

Acute esophageal obstruction after ingestion of psyllium seed husk powder: A case report.

Background: Bezoar is a mass of hardened external material found in the gastrointestinal (GI) tract. It may form anywhere in the GI tract, but esophageal bezoar is rare because of the short esophageal transit time. Psyllium seed husk is an indigestible natural derivative that is widely used as an herbal laxative.

Preparedness of personal protective equipment and implementation of new CPR strategies for patients with out-of-hospital cardiac arrest in the COVID-19 era.

Background: In February and March 2020, healthcare providers and citizens in Daegu, South Korea, experienced the onslaught of a large-scale community epidemic of COVID-19. This had a profound impact on patients who experienced out-of-hospital cardiac arrest (OHCA).

Methods: We conducted a retrospective observational study of 171 OHCA patients based on the multicenter WinCOVID registry.

Delays in the Management of Patients with Acute Ischemic Stroke during the COVID-19 Outbreak Period: A Multicenter Study in Daegu, Korea.

Background: Timely treatment is important for patients with acute ischemic stroke (AIS). However, the coronavirus disease 2019 (COVID-19) outbreak may have caused delays in patient management. Therefore, we analyzed the prognosis and the time spent at the prehospital and hospital stages in managing patients diagnosed with AIS during the COVID-19 outbreak.

External validation of multimodal termination of resuscitation rules for out-of-hospital cardiac arrest patients in the COVID-19 era.

Background: Futile resuscitation for out-of-hospital cardiac arrest (OHCA) patients in the coronavirus disease (COVID)-19 era can lead to risk of disease transmission and unnecessary transport. Various existing basic or advanced life support (BLS or ALS, respectively) rules for the termination of resuscitation (TOR) have been derived and validated in North America and Asian countries. This study aimed to evaluate the external validation of these rules in predicting the survival outcomes of OHCA patients in the COVID-19 era.

Confirmation of COVID-19 in Out-of-Hospital Cardiac Arrest Patients and Postmortem Management in the Emergency Department during the COVID-19 Outbreak.

Background: There is currently a lack of evidence-based postresuscitation or postmortem guidelines for patients with out-of-hospital cardiac arrest (OHCA) in the setting of an emerging infectious disease. This study aimed to develop and validate a multimodal screening tool that aids in predicting the disease confirmation in emergency situations and patients with OHCA during a coronavirus disease 2019 (COVID-19) outbreak.

Materials And Methods: We conducted a retrospective, multicenter observational study of adult patients with OHCA in Daegu, Korea.

QRS complex characteristics and patient outcomes in out-of-hospital pulseless electrical activity cardiac arrest.

Background: Pulseless electrical activity (PEA) is increasingly observed in out-of-hospital cardiac arrest (OHCA), but outcomes are still poor. We aimed to assess the relationship between QRS characteristics and outcomes of patients with OHCA with initial PEA (OHCA-P).

Methods: This prospective observational study included patients aged at least 18 years who developed OHCA-P between 1 January 2016 and 31 December 2018, and were enrolled in the Daegu Emergency Medical Services registry, South Korea.

Application of a Dual-Dispatch System for Out-of-Hospital Cardiac Arrest Patients: Will More Hands Save More Lives?

Background: Recovery after out-of-hospital cardiac arrest (OHCA) is difficult, and emergency medical services (EMS) systems apply various strategies to improve outcomes. Multi-dispatch is one means of providing high-quality cardiopulmonary resuscitation (CPR), but no definitive best-operation guidelines are available. We assessed the effects of a basic life support (BLS)-based dual-dispatch system for OHCA.
