Pulmonary edema and LIS were not affected by the type of fluid loading in the
steep part of the cardiac function curve in both septic and nonseptic patients
About 300 mL more crystalloid than colloid fluids were administered

POSSUM physiology scores ranged from 12 to 52
POSSUM operative severity scores ranged from 6 to 37
The cohort had a mean (s.d.) (median, interquartile range) operative
severity score of 16·5 (6·2) (16, 11–20)
Overall, the mean (s.d.) (median, interquartile range) postoperative length
of stay in hospital was 11·8 (11·6) (9, 5–14) days
Observed death rate was 9.9%

recruited ; October-December 2011 : dissemination of findings
• Research questions
– 1. What is the in-hospital mortality rate for patients undergoing non-cardiac surgery?
– 2. What is the duration of hospital stay?
– 3. What is the current standard of peri-operative critical care provision?
– 4. What is the current standard of haemodynamic (cardiac output) monitoring?

– 6. Is there any evidence of differences in hospital stay and mortality?
– 7. What factors determine planned and unplanned admission to critical care after
surgery?
– 8. Are the factors associated with critical care admission similar to those associated with
post-operative death?

46539 pts, 1855 died (4.0%)
3585 pts (7.7%) admitted to Critical Care [length
of stay of 1.2 days (0.9-3.6)]
73% of patients who died were not admitted to
Critical Care at any stage after surgery
The following factors were found to be
independently related to hospital death: age,
ASA score, country, surgical procedure, urgency
of surgery, grade of surgery, metastatic disease,
cirrhosis
Both crude hospital mortality rates
and adjusted odds ratios varied widely between countries (OR 0.45 [95% CI 0.14-1.4] to 10.9 [7.5-
15.8]) as did critical care admission rates (0 -
16.1%)

• There is little evidence to support preferential use of any particular type of fluid during esophageal Doppler guided optimization
• Many of these fluids have not been evaluated in patient populations in whom optimization is being applied or proposed, and the potential for harm cannot be excluded

• 13. In patients undergoing some forms of orthopaedic and abdominal surgery, intra-operative treatment with intravenous fluid to achieve an optimal value of SVshould be used where possible as this may reduce postoperative complication rates and duration of hospital stay
– Orthopaedic surgery: Evidence level 1b
– Abdominal surgery: Evidence level 1a
• 4. In « High Risk Surgical Patients, it is recommended to titrate intraoperative fluid loading by guiding the SV in order to reduce postoperative morbidity, hospital length of stay, and in patients benefiting from digestive surgery, the digestive function recovery (strong agreement)

• The patients in the Vigileo group received more colloid (1425 ml [1000-1500]
vs. 1000 ml [540-1250]; P = 0.0028) intraoperatively
• Fewer Vigileo patients developed complications (18 (30%) vs. 35 (58.3%)
patients; P = 0.0033)
• The overall number of complications was also reduced (34 vs. 77

• 3) Il peut être réalisé par monitorage de la PPV-SVV chez le patient sédaté-intubé-ventilé et/ou le suivi de la réponse au remplissage
• Pour le PPV : En rythme sinusal et un ratio HR/RR >3.5
• Pour le débit cardiaque : Avec un moniteur invasif ou non
