PURPOSES An abdominal inflammatory focus is the second most often source of sepsis with a high risk of death in surgical intensive care units. By establishing evidence-based bundled strategies the surviving sepsis campaign provided an optimized rapid and continuous treatment of these emergency patients. Hereby the hospital mortality decreased from 35 to 30(More)
Catecholamine and serotonin concentrations in the cord, medulla, and hypothalamus were measured in rats after saline, after sufentanil sufficient to reduce the minimum alveolar concentration (MAC) of halothane by 30% or less, or after sufentanil sufficient to reduce the MAC of halothane by 80% or more. In the cord, high doses of sufentanil resulted in a(More)
