Instead, two chairpersons will conduct, in front of each poster, a short discussion of each abstract with the presenter and the audience, for every abstract in that session. Poster presenters have been asked to stand by their poster at least 15 minutes before the start of the session and 15 minutes after, to address further questions.

To evaluate the effectiveness of a personalised preoperative pMreethhaobdilsit:a tion intervention on postoperative outcomes in high-risk patients undergoing major abdominal surgery. Randomised double-blind controlled trial. 144 high-risk patients (>70 yrs-old and/or ASA III/IV) planned for elective major abdominal sur- gery were randomised to prehabilitation program or standard preoperative care. The intervention encompassed three steps: i) motivational interview; ii) personalized program to promote physical activity; and, iii) supervised en- durance training program. The main outcome of study was the proportion of patients suffering from postoperative complications. Secondary outcome variables were: i) hospital and intensive care unit (ICU) days of stay; and, ii) endurance time measured by a cycling2 constant work-rate exercise testing. CRoesmupltasr:is ons have been done using chi or Fisher’s exact tests for categorical variables, and Student’s or Wilcoxon tests for numerical variables. 125 patients (prehabilitation group n=62 and control group n=63) (71±10 yrs-old, 75% male) were finally included in the intention-to-treat analy- sis. At program discharge [duration 6 (2) weeks], the prehabilitation group showed an improvement of 135 (218) % in the endurance time (p<0.001) meanwhile the· control grou·p r·emained unchanged. The intervention group showed 20% less of patients with postoperative complications compared with controls (RR 05, 95% CI [03-08]; p=0.001). The intervention group showed shorter in-hospital stay, although no statistical significant showed up [8 (8) vs. 13 (20) days (p=0.078)]. A sensitivity analysis including only those patients aCdomncitltuesdi oinn tsh:e ICU (n=44), showed a significant reduction of ICU stay in the intervention group [3 (2) vs. 12 (20) days; p=0.046]. Prehabilitation is effective reducing morbidity rates in high-risk patients undergoing major abdominal surgery. Easier alternatives based on moderate-intensity exercise programs and the role of including nutritional and psychological support should be investigated in future research. Supported by ESA Grant.

Following a lung recruitment maneuver and a decremental distribution PEEP trial (26 cmH2O - 6 cmH2O) respiratory system mechanics and regional TP was determined for each PEEP level. The best-PEEP level was defined as the lowest PEEP yielding positive end-expiratory TP in all lung regions.
