Abstract

Most clinical studies have so far focused on the regional effects of epinephrine (i.e. hepato-splanchnic blood flow) in septic patients. In cardiac surgical patients, however, inotropic (i.e. epinephrine) support is often necessary for optimizing cardiac output postoperatively. We tested whether increasing cardiac output by epinephrine leads to an improved regional (i.e. hepato-splanchnic) blood flow and function.

Results Patient characteristics (mean ± SD): age 57.4 ± 15.4 years, 28 female, 52 male, APACHE II score 28.2 ± 6.6; number of organ failures 4.0 ± 1.12; preceding ICU period 8.5 ± 9.3 days; continuous sedation with midazolam 31.2 ± 34.2 mg/hour, fentanyl 0.12 ± 0.08 mg/hour, propofol 45.6 ± 105.2 mg/hour; sedation assessment according to RS 5.65 ± 0.63, CPS 5.15 ± 1.67, CKS 0.65 ± 0.69, CS 9.34 ± 2.13 und LSS 1.78 ± 1.69, RASS –4.50 ± 1.27, FiO2 0.52 ± 0.17, PEEP 8.2 ± 2.4 cmH2O, ventilatory frequency 20.5 ± 4.8/min, pressure control 16.8 ± 4.4 cmH2O, tidal volume 540 ± 115 ml, TVV 2525.6 ± 11,366 ml (minimum 1.52; maximum 91,586). We hypothesized that S100β levels correlate with this tumor’s preoperative characteristics and with perioperative neurological injury despite its supratentorial location and non-neural origin
