Whether this association is centre-specific or more generalisable is not known. The aim of this study was to assess the association between peri- and postoperative ScvO2 and outcome in high-risk surgical patients in a multicentre setting. Methods Three large European university hospitals two in Finland one in Switzerland participated. In 60 patients with intra-abdominal surgery lasting more than 90 minutes the presence of at least two of Shoemaker s criteria and ASA American Society of Anesthesiologists class greater than 2 ScvO2 was determined preoperatively and at two hour intervals during the operation until 12 hours postoperatively. Hospital length of stay LOS mortality and predefined postoperative complications were recorded. Results The age of the patients was 72 10 years mean standard deviation and simplified acute physiology score SAPS II was 32 12. Hospital LOS was 8 to 14 .
