Abstract
We recently showed in a hyperdynamic mouse model of septic shock that endogenous glucose production is depressed [1]. However, the mechanism for this depression remains unclear. In this context, the role of excess NO release due to activation of the inducible isoform of the NO synthase (iNOS) has been controversially discussed: while Stadler reported a direct relation between excess NO release and the inhibition of gluconeogenesis [2], other authors did not demonstrate any NO effect [3]. We therefore investigated the effects of genetic iNOS deletion on hepatic glucose production in a clinically relevant murine model of normotensive, hyperdynamic, volume-resuscitated septic shock. Wild-type mice served as controls.

Computer-advised insulin infusion in postoperative cardiac surgery patients: a randomized prospective controlled multicenter trial quality the alveoli are observed at an open chest wall under a glass plate representing an artificial situation. To circumvent this restriction we developed a method of intravital endoscopy and tested it on an animal rat model

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
