Abstract
Cardiovascular dysfunction (CD) occurs frequently among patients with septic shock and it is more severe in the first 3 days, relapsing at the end of the first week among those who survive. Fifteen percent of the patients with septic shock, who evolve to death, die as a result of CD, whose physiopathologic mechanisms are not fully understood. Levosimedan (LEVO), a new inotropic drug which acts as calcium sensitizing agent and also has effects on potassium channels in vascular smooth muscle cells leading to vasodilatation action, has shown benefits in patients with cardiac failure. An experimental study on the endotoxic shock model has shown improvement on cardiac output, and systemic and regional oxygenation. The aim of this study is to prove the acute hemodynamic effects of LEVO administration on septic patients with severe CD.
Highlights
Cardiac surgery with cardiopulmonary bypass (CPB) is a recognized trigger of systemic inflammatory response, usually related to postoperative acute lung injury (ALI)
The objective was to evaluate the characteristics of Chest pain (CP) in patients with acute aortic dissection (AAD) admitted in a chest pain unit (CPU)
Patients and methods We evaluated in a cross-sectional and prospective study patients admitted in a CPU, between March 1997 and May 2001, with diagnosis of AAD
Summary
Cardiac surgery with cardiopulmonary bypass (CPB) is a recognized trigger of systemic inflammatory response, usually related to postoperative acute lung injury (ALI). Few studies exist analysing the handling of acute respiratory insufficiency with invasive mechanical ventilation (IMV) and its correlation with mortality among the elderly intensive care unit (IUC) patient population. In Brazil, most patients with TBI are managed in general ICUs. The results of the treatment of patients admitted to nonspecialized ICUs must be compared with those obtained in neurosurgical ICUs. An acute confusional state (ACS) has been a frequent finding in patients undergoing cardiac surgery (CS), which, according to the literature, has resulted in a greater number of complications and in an increase in hospitalization and length of stay in the intensive care unit (ICU). The mortality of elderly patients who are admitted to intensive care units (ICU) has been the aim of some recent studies. Drugs that modulate such phenotypic alterations may be useful in the control of these and other clinical situations
