ReviewTreatment of stroke on an intensive stroke unit: a novel concept.
In industrialised nations stroke ranks as number three among causes of death and is the most frequent cause of disability in old age. Demographic changes will result in stroke gaining increasing importance for individuals as well as for society as a whole. Stroke is already a major cost factor for healthcare and social security systems because of its high long-term costs. ⋯ We would like to stress at this point that this manuscript is a personal view describing stroke care in Germany. Many of the principles described have not been widely adopted elsewhere, perhaps in part due to a lack of available facilities. However, many of our recommendations are based on logical principles and thus, we feel, bear further scrutiny.

Acute respiratory distress syndrome in trauma patients: ICU mortality and prediction factors.
To study the factors that influence the intensive care unit (ICU) mortality of trauma patients who develop acute respiratory distress syndrome (ARDS) and to evaluate determinants of length of ICU stay among these patients. ⋯ The ICU mortality of trauma patients with ARDS is related to the APACHE III score, the gas exchange evolution as measured by the PaO2/FIO2 on the 3rd day and the progressive complications indicated by the onset of MSOF. The length of ICU stay of these patients is related to the number of days on mechanical ventilation.

Clinical TrialThe renal and neurohumoral effects of the addition of low-dose dopamine in septic critically ill patients.
Dopamine exerts a complicated action on the cardiovascular-renal and neurohumoral systems. We evaluated the effects of the addition of different doses of dopamine on top of treatment with norepinephrine on the haemodynamics, renal function and neurohormones of septic shock patients. ⋯ During norepinephrine infusion, increasing doses of dopamine from 2 to 6 microg x kg(-1) x min(-1) augments CO, diuresis and sodium excretion in patients treated for septic shock, without changes in creatinine clearance. Higher doses of dopamine (4 and 6 microg x kg(-1) x min(-1)) also induce an increase in heart rate. PRA, aldosterone and norepinephrine levels remain unchanged during dopamine infusion.

To examine the relationship between end-tidal CO2 (PETCO2) and its physiological determinants, pulmonary blood flow (cardiac output, CO) and CO2 production (VCO2), in a model of hemorrhagic shock during fixed minute ventilation. ⋯ Our data reconfirm the relationship between PETCO2 and CO during hemorrhagic shock. The relatively greater decrease in PETCO2 at lowest CO levels could represent diminished CO2 production during the period of VO2 supply dependency.

High survival in adult patients with acute respiratory distress syndrome treated by extracorporeal membrane oxygenation, minimal sedation, and pressure supported ventilation.
To evaluate the results of treatment of severe acute respiratory distress syndrome (ARDS) with extracorporeal membrane oxygenation (ECMO), minimal sedation, and pressure supported ventilation. ⋯ A high survival rate can be obtained in adult patients with severe ARDS using ECMO and pressure-supported ventilation with minimal sedation. Surgical complications are amenable to surgical treatment during ECMO. Bleeding problems can generally be controlled but require immediate and aggressive approach. It is difficult or impossible to decide when a lung disease is irreversible, and prolonged ECMO treatment may be successful even in the absence of any detectable lung function.
