Preoperative Evaluation of Microcirculation for Prediction of Complications After Cardiac Surgery

Not Applicable
Completed
Conditions
Extracorporeal Circulation; Complications
Interventions
Procedure: Microvascular reactivity evaluation
Registration Number
NCT03631797
Lead Sponsor
University Hospital, Angers
Brief Summary

Cardiac surgery is responsible for many complications. Microcirculation is involved in many of them. The objective of this study is to prospectively investigate the prognostic value of preoperative microcirculatory assessment in patients scheduled for cardiac surgery with CPB for the occurrence of postoperative complications.

Microvascular dysfunction is suspected of being involved in postoperative psycho-cognitive decline. The influence of microcirculation on the evolution of psycho-cognitive assessment is also analyzed in this study.

Detailed Description

Eligible patients are included during the preoperative assessment. Written consent is signed after complete explanation of the protocol.

Patient characteristics as treatments, medical history, and EuroSCORE II are registered. Moreover, intraoperative data is collected. Psycho-cognitive and functional evaluation is made preoperatively.

Microcirculation is evaluated for each patient before surgery. Complications are registered at the end of hospital stay. Psycho-cognitive and functional evaluation is repeated by call 30 days after the surgery.

Primary Outcome Measures
NameTimeMethod
Postoperative complication30 postoperative days

Composite criteria and include microcirculation postoperative complications:

* Late surgical re-intervention (greater than 12 hours) for evacuation of pericardial effusion (seeps),

* Surgical wound disunion or surgical site infection,

* Organ failure: SOFA score greater than 2 at 48h,

* Postoperative confusion: assessed using the Confusion Assessment Method (CAM) or the Confusion Assessment Method for the Intensive Care Unit (CAM-ICU),

* Acute renal failure ≥ stage 2 according to the KDIGO classification,

* Acute lung injury defined as PaO2 \<55mmHg in ambient air, PaO2 / FiO2 ratio \<250 or Pulse Oxygen Saturation (SpO2) \<90% and need for oxygen therapy,
