For anaphylaxis, a life-threatening allergic reaction, the incidence rate was presented to have increased from the beginning of the 21st century. Underdiagnosis and undertreatment of anaphylaxis are public health concerns. This guideline aimed to provide high-quality and evidence-based recommendations for the emergency management of anaphylaxis.

Objective: This study aimed to investigate the predictive value of pulse oximetry plethysmography (POP) for the return of spontaneous circulation (ROSC) in cardiac arrest (CA) patients.

Methods: This was a multicenter, observational, prospective cohort study of patients hospitalized with cardiac arrest at 14 teaching hospitals cross China from December 2013 through November 2014. The study endpoint was ROSC, defined as the restoration of a palpable pulse and an autonomous cardiac rhythm lasting for at least 20 minutes after the completion or cessation of CPR.

Background: Acute heart failure (AHF) is the most common disease in emergency departments (EDs). However, clinical data exploring the outcomes of patients presenting AHF in EDs are limited, especially the long-term outcomes. The purposes of this study were to describe the long-term outcomes of patients with AHF in the EDs and further analyze their prognostic factors.

Article Synopsis
  • The study compares intraosseous (IO) access and central venous catheterization (CVC) for emergency vascular access in critically ill patients across eight hospitals in China.
  • IO access showed a significantly higher success rate on the first attempt (91.7% vs. 50.0%) and took much less time (52 seconds vs. 900 seconds) compared to CVC.
  • There was no notable difference in operator satisfaction or complications between the two methods, and while pain scores for insertion were similar, IO infusion caused slightly more discomfort than CVC.

Whether the anemia increases the risk of mortality in patients with acute heart failure (AHF) remains unclear. This study aims to explore the relationship between anemia and outcomes in patients with AHF including subgroup analysis. This study included 3279 patients with hemoglobin available from the Beijing Acute Heart Failure Registry (Beijing AHF Registry) study.

Background: This systemic review aimed to explore the predictors of discharge and neurologic outcome of adult extracorporeal cardiopulmonary resuscitation (ECPR) to provide references for patient selection.

Methods: Electronically searching of the Pubmed, Embase, Cochrane Library, and manual retrieval were done for clinical trials about predictors for adult ECPR which were published between January 2000 and January 2018 and included predictors for discharge and neurologic outcome. The literature was screened according to inclusion and exclusion criteria, the baseline information and interested outcomes were extracted.

Background: The emergency department (ED) has a pivotal influence on the management of acute heart failure (AHF), but data concerning current ED management are scarce. This Beijing AHF Registry Study investigated the characteristics, ED management, and short- and long-term clinical outcomes of AHF.

Methods: This prospective, multicenter, observational study consecutively enrolled 3335 AHF patients who visited 14 EDs in Beijing from January 1, 2011, to September 23, 2012.

Background: Since the 1980s, severity of illness scoring systems has gained increasing popularity in Intensive Care Units (ICUs). Physicians used them for predicting mortality and assessing illness severity in clinical trials. The objective of this study was to assess the performance of Simplified Acute Physiology Score 3 (SAPS 3) and its customized equation for Australasia (Australasia SAPS 3, SAPS 3 [AUS]) in predicting clinical prognosis and hospital mortality in emergency ICU (EICU).

Objective: To analyze the distribution of pathogens and bacterial drug resistance for acute exacerbation of chronic obstructive pulmonary disease (AECOPD) in patients hospitalized frequently for AECOPD versus those with infrequent admissions.

Methods: A total of 172 patients admitted into Peking University Third Hospital for AECOPD from January 2007 to December 2008 were recruited. According to the frequency of AECOPD-related hospitalization during the previous year, they were divided into two groups of frequently hospitalized ( ≥ 2 hospitalizations due to AECOPD during the previous year) and infrequently hospitalized (<2 hospitalizations due to AECOPD during the previous year).

Background: Although pulmonary embolism (PE) with normal blood D-dimer (DD) concentrations is considered rare, in practice the incidence may be greater than is generally believed. Overlooking PE is potentially dangerous. The aim of this study was to explore the incidence and clinical features of PE with normal DD concentrations.

Objective: To investigate the role of plasma D-dimer in differentiating fatal chest pain due either to acute myocardial infarction (AMI), acute pulmonary embolism (APE) or acute aortic dissection (AAD) in emergency department.

Methods: The data of a total of 445 consecutive patients complaining chest (back) pain and/or dyspnea who visited emergency department of Peking University Third Hospital from January 2011 to January 2012 were retrospectively analyzed. All cases were either diagnosed as AMI, APE or AAD finally.

Background: Underlying diseases have a statistically significant positive correlation to sudden death. However, sudden unexplained death (SUD) is different from sudden death, as there is no clinical evidence to support the sudden death due to the original underlying disease, nor a lethal pathological basis to be found during autopsy. In addition, SUD are more common in young, previously healthy individuals, usually without any signs of disease, with no positive lesions found after autopsy.

Objective: To quantitatively evaluate the influences of daily mean air temperature (DMT) on Emergency Department Visits (EDVs) for the respiratory diseases.

Methods: The EDV data from medical records for respiratory diseases in Peking University Third Hospital between January 2004 and June 2009 were collected. The data of the air pollutants (SO(2), NO(2) and PM(10)) and meteorological factors at the same time periods were also collected from the local authorities of Beijing.

Background: Pulmonary embolism (PE) is rare and seldom considered in adolescent patients; however it occurs with a greater frequency than is generally recognized, and it is a potentially fatal condition. The aim of the current study was to understand its epidemiology, clinical features and the cause of delay of its diagnosis in adolescents.

Methods: A retrospective analysis of nine adolescents with acute PE admitted to the Peking University Third Hospital over the past 16-year period was performed.

Objective: To compare the efficacy and safety of ibutilide versus propafenone in immediate cardioversion of atrial fibrillation (AF) and atrial flutter (AFL) lasted less than 90 days.

Methods: 212 consecutive patients suffering from AF or AFL all lasting less than 90 days that were diagnosed and treated in 5 medical centers were randomly assigned into two groups: ibutilide group (n = 107, including 75 AF cases and 32 AFL cases, receiving intravenous injection of ibutilide 1mg over 10 minutes) and propafenone group as control group (n = 105, including 76 AF cases and 29 AFL cases, receiving intravenous injection of propafenone 70 mg over 10 minutes). If AF/AFL still persisted 10 minutes after treatment, the above dose was repeated.
