Extracorporeal cardiopulmonary resuscitation showed a survival benefit over conventional cardiopulmonary resuscitation in patients who received cardiopulmonary resuscitation for >10 mins after witnessed inhospital arrest, especially in cases with cardiac origins.

IntroductionThe aim of this study is to evaluate the effects of emergency department (ED) crowding on the implementation of tasks in the early resuscitation bundle during acute care of patients with severe sepsis and septic shock, as recommended by the Surviving Sepsis Campaign guidelines.MethodsWe analyzed the sepsis registry from August 2008 to March 2012 for patients presenting to an ED of a tertiary urban hospital and meeting the criteria for severe sepsis or septic shock. The ED occupancy rate, which was defined as the total number of patients in the ED divided by the total number of ED beds, was used for measuring the degree of ED crowding. It was categorized into three groups (low; intermediate; high crowding). The primary endpoint was the overall compliance with the entire resuscitation bundle.ResultsA total of 770 patients were enrolled. Of the eligible patients, 276 patients were assigned to the low crowding group, 250 patients to the intermediate crowding group, and 244 patients to the high crowding group (ED occupancy rate: ≤ 115; 116–149; ≥ 150%). There was significant difference in compliance rates among the three groups (31.9% in the low crowding group, 24.4% in the intermediate crowding group, and 16.4% in the high crowding group, P < 0.001). In a multivariate model, the high crowding group had a significant association with lower compliance (adjusted odds ratio (OR), 0.44; 95% confidence interval (CI), 0.26 to 0.76; P = 0.003). When the ED occupancy rate was included as a continuous variable in the model, it had also a negative correlation with the overall compliance (OR of 10% increase of the ED occupancy rate, 0.90; 95% CI, 0.84 to 0.96, P = 0.002).ConclusionsED crowding was significantly associated with lower compliance with the entire resuscitation bundle and decreased likelihood of the timely implementation of the bundle elements.

Clinical deterioration among hemodynamically stable sepsis patients occurs frequently, and patients with intermediate lactate levels (between 2.0 and 4.0 mmol/L) are particularly at risk for mortality. The aim of this study was to identify factors for predicting early deterioration in sepsis patients with intermediate levels of serum lactate. A retrospective cohort study of adult sepsis patients with lactate levels between 2.0 and 4.0 mmol/L was conducted in the emergency department of a tertiary care hospital between August 2008 and July 2010. The primary outcome was progression to sepsis-induced shock defined as persistent hypotension despite initial fluid challenge or a blood lactate concentration 4 mmol/L or greater within 72 hours of emergency department arrival. Among the 474 patients enrolled in the study, there were 108 cases of sepsis-induced tissue hypoperfusion (22.7%) and 48 deaths (10.1%). In a multivariate regression analysis, independent predictors for progression were hyperthermia, neutropenia, band neutrophils appearance, hyponatremia, blood urea nitrogen level, serum lactate level, and organ failure including respiratory, cardiovascular, and central nervous system. Initial Sequential Organ Failure Assessment score was also associated with progression. In patients with a Sequential Organ Failure Assessment score of 5 or greater, the predicted rate of progression to tissue hypoperfusion was 38.9%. Our study demonstrates potential risk factors, including organ failure, for progression to sepsis-induced tissue hypoperfusion in patients with intermediate levels of serum lactate. We suggest that an early aggressive treatment strategy is needed in patients with these risk factors.
