OBJECTIVE To determine associations between intensive care resource utilisation and centre-, patient- and procedure-related factors. DESIGN Prospective multicentre cohort study. SETTING Twenty-one European intensive care units. PATIENTS AND PARTICIPANTS Four thousand four hundred adult patients who had undergone cardiac or thoracic aortic surgery in(More)
BACKGROUND Weaning of patients from mechanical cardiac support after myocardial recovery has always involved multiple, interacting factors, particularly the training of the myocardium during reduction of pump flow. Rotary pumps offer training advantages when support flow is reduced, even to nearly zero. We report a computer analysis that evaluates the work(More)
AIMS Uncoupled endothelial nitric oxide synthase (eNOS) is a major contributor to vascular reactive oxygen species generation in ischaemia/reperfusion (I/R) injury. Supplementation of NO by the novel NO donor S-nitroso human serum albumin (S-NO-HSA) may inhibit uncoupling of eNOS (feedback inhibition). METHODS AND RESULTS Pigs (n = 14; 33.1 +/- 1.7 kg)(More)
Sepsis causes lymphopenia which is inversely correlated with patient survival. The role of apoptosis-specific immune-activation and activation-induced cell-death in sepsis is incompletely understood. Fifteen septic patients and 20 healthy controls were included. T-cell proliferation was measured by [3H]thymidine uptake. Apoptosis and cell phenotype were(More)
UNLABELLED The effect of normothermic (36.2 degrees C +/- 0.6 degree C) nonpulsatile cardiopulmonary bypass (CPB) on splanchnic (hepatic) blood flow (SBF), splanchnic oxygen transport (DO2spl) and oxygen consumption (VO2spl), splanchnic lactate uptake and gastric mucosal pH (pHi, gastric tonometry) was studied in 12 adults (New York Heart Association class(More)
The mucosa of the small intestine has some unique microcirculatory features that may result in significant tissue oxygenation changes even under physiological conditions. To prove this hypothesis we investigated mucosal and serosal oxygenation in an autoperfused, innervated jejunal segment in pigs. Eight animals (30-40 kg) were anesthetized, paralyzed, and(More)
Effects of Escherichia coli lipopolysaccharide (2 micrograms.kg-1.20 min-1; LPS), given systemically (S) or via superior mesenteric artery (M), and consecutive dopamine infusion (16 micrograms.kg-1.20 min-1) on jejunal mucosal tissue O2 tension (PO2muc) and serosal tissue O2 tension (PO2ser; Clark-type surface electrodes) and jejunal mucosal microvascular(More)
Nitric oxide (NO) supplementation may modify myocardial oxygen consumption and vascular function after ischemia. We investigated the effects of the NO donor, S-nitroso human serum albumin (S-NO-HSA), on cardiac oxygen metabolism during controlled reperfusion on normothermic cardiopulmonary bypass after severe myocardial ischemia. Pigs randomly received(More)
The effect of intravenously delivered dopamine on jejunal tissue oxygenation was studied in 12 pigs anesthetized with midazolam and sufentanil and mechanically ventilated. A small segment of the jejunal mucosa and serosa was exposed by midline laparotomy and antimesenteric incision. Mucosal and serosal tissue PO2, mucosal microvascular hemoglobin oxygen(More)
OBJECTIVE To evaluate the effects of dopamine-1-receptor stimulation on intestinal mucosal tissue oxygenation. DESIGN Prospective, experimental, controlled trial. SETTING Animal research laboratory. SUBJECTS Anesthetized domestic pigs (30 to 45 kg). INTERVENTIONS A small segment of the jejunal mucosa and serosa was exposed by midline laparotomy and(More)
