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.

The impact of age and receipt antihypertensives to systolic blood pressure and shock index at injury scene and in the emergency department to predict massive transfusion in trauma patients.

Background: Systolic blood pressure (SBP) and shock index (SI) are accurate indicators of hemodynamic instability and the need for transfusion in trauma patients. We aimed to determine whether the utility and cutoff point for SBP and SI are affected by age and antihypertensives.

Methods: This was a retrospective observational study of a level 1 trauma center between January 2017 and December 2018.

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.

Long-term benefits of chest compression-only cardiopulmonary resuscitation training using real-time visual feedback manikins: a randomized simulation study.

Objective: Cardiopulmonary resuscitation (CPR) education with a feedback device is known to result in better CPR skills compared to one without the feedback device. However, its long-term benefits have not been established. The purpose of this study was to evaluate the long-term CPR skill retention after training using real-time visual manikins in comparison to that of non-feedback manikins.

Association of response time interval with neurological outcomes after out-of-hospital cardiac arrest according to bystander CPR.

Background: This study intended to find out how association between response time interval (RTI) and good neurological outcome is affected by bystander CPR. We hypothesized that bystander CPR will ensure positive effect in relationship between RTI and clinical outcome.

Methods: A retrospective, observational study was made with Pan-Asian Resuscitation Outcome Study data from January 2009 to December 2016.

Comparing the neurologic outcomes of patients with out-of-hospital cardiac arrest according to prehospital advanced airway management method and transport time interval.
