Primary Outcome Measures

Name	Time	Method
Time proportion (out of the anesthesia duration) with pressure outside the near-normal values (patients normal +/- 20%). <br>Analysis per retrospective off-line analysis of continuous pressure readings: Time duration of periods with systolic pressure above the patients normal + 20% or below the pateints normal - 20% will be sumed up. Proportion of these times to total anesthesia duration will be assessed.[Anesthesia duration];Time proportion (out of the anesthesia duration) with hypotension (patients normal - 20%).<br>Analysis per retrospective off-line analysis of continuous pressure readings: Time duration of periods with systolic pressure below the pateints normal - 20% will be sumed up. Proportion of these times to total anesthesia duration will be assessed.[Anesthesia duration]

Secondary Outcome Measures

Name	Time	Method
Difference in the Short Orientation Memory Concentration Test[baseline (at preanesthesia visit), 20 + 60 minutes after waking from anesthesia];Number and rate of postoperative complications (infectious and organ complications - based on the list used in the POSSUM scoring system). Minor screened complications incl. postoperative nause and vomiting, anemia requiring transfusion, fever etc. Major complications incl. organ failure, reoperation, surgical site infection, sepsis, pneumonia etc.<br>Complications will be assessed per daily visits of treating physician (not member of the study team) and summarized before discharge by a blinded study team member.[Postoperatively until discharge.]
