Survivors of out-of-hospital cardiac arrest with apparently normal heart. Need for definition and standardized clinical evaluation. Consensus Statement of the Joint Steering Committees of the Unexplained Cardiac Arrest Registry of Europe and of the Idiopathic Ventricular Fibrillation Registry of the United States.

BACKGROUND: A wide variety of structural abnormalities are associated with the vast majority of cardiac arrests. However, there is no evidence of structural heart disease in approximately 5% of victims of sudden death, indicating that cardiac arrest in the absence of organic heart disease is more common than previously recognized. The risk of recurrence and the acute and long-term response to therapy are important but unanswered questions. Data from the small series reported so far are of limited value because of the lack of uniform criteria to define and diagnose idiopathic ventricular fibrillation (IVF). METHODS AND RESULTS: This report originates from a Consensus Conference convened by the Steering Committees of the European (UCARE) and North American (IVF-US) Registries on IVF under the auspices of the Working Group on Arrhythmias of the European Society of Cardiology. Its objective is to provide a unified definition of IVF and to outline the investigations necessary to make this diagnosis. Minimal diagnostic tests for the exclusion of an underlying structural heart disease include non-invasive (blood biochemistry, physical examination and clinical history, ECG, exercise stress test, 24-hour Holter recording, and echocardiogram) and invasive (coronary angiography, right and left ventricular cineangiography, and electrophysiological study) examinations. Programmed electrical stimulation, ventricular biopsy, and ergonovine test during coronary angiography are recommended but not mandatory. CONCLUSIONS: It is recognized that despite careful evaluation, conditions such as focal cardiomyopathy, myocarditis, or fibrosis and transient electrolyte abnormalities may remain silent. Therefore, patients should undergo careful follow-up, with noninvasive tests repeated every year. The existence of a unified terminology will allow meaningful comparison of data collected by different investigators and will thus contribute to a better understanding of IVF.

North American Summit on Aspiration in the Critically Ill Patient: consensus statement.

Aspiration is the leading cause of pneumonia in the intensive care unit and the most serious complication of enteral tube feeding (ETF). Although aspiration is common, the clinical consequences are variable because of differences in nature of the aspirated material and individual host responses. A number of defense mechanisms normally present in the upper aerodigestive system that protect against aspiration become compromised by clinical events that occur frequently in the critical care setting, subjecting the patient to increased risk. The true incidence of aspiration has been difficult to determine in the past because of vague definitions, poor assessment monitors, and varying levels of clinical recognition. Standardization of terminology is an important step in helping to define the problem, design appropriate research studies, and develop strategies to reduce risk. Traditional clinical monitors of glucose oxidase strips and blue food coloring (BFC) should no longer be used. A modified approach to use of gastric residual volumes and identification of clinical factors that predispose to aspiration allow for risk stratification and an algorhythm approach to the management of the critically ill patient on ETF. Although the patient with confirmed aspiration should be monitored for clinical consequences and receive supportive pulmonary care, ETF may be continued when accompanied by appropriate steps to reduce risk of further aspiration. Management strategies for treating aspiration pneumonia are based on degree of diagnostic certainty, time of onset, and host factors.
