ABSTRACT
In recent years, several epidemiological studies have helped expand our knowledge of the incidence of sepsis at the intensive care unit (ICU) and population levels. However, more data are needed from developing countries. Overall, even with a lack of standardized definitions--particularly of sepsis-associated organ dysfunction, hypoperfusion or hypotension, and septic-induced cardiovascular failure despite adequate fluid resuscitation--the incidence of sepsis seems higher in Brazil, the United Kingdom, and Portugal. In the future, in order to better identify patients that need early ICU admission, aggressive care, and new therapies, we must develop and apply better instruments for definition and risk stratification, especially for evaluating the risk of progressing from sepsis to severe sepsis and septic shock.
ABSTRACT
The use of echocardiography is still far from optimal. It is difficult or impossible to ensure the 24-hour presence at a hospital of a cardiologist with experience in echocardiography. As a result other specialties are becoming familiar with this technique. Echocardiography has been recognized as of paramount importance in diagnosis, prognosis and therapeutic decisions in several diseases and therefore echocardiographic training with different levels of experience should be supported and coordinated by a reference group in such matters. The authors review some aspects of echocardiography in emergency. They emphasize the importance of continuous training and accreditation as required conditions to perform echocardiography.
