Cerebral Saturation, Cognitive Impairment, Emergencies
Conditions
Brief summary
There is no study of the association between ScO2 and POCD in non-cardiac, thoracic or vascular surgery. The few studies found in cardiac, thoracic and vascular surgery show an incidence up to 50% with a variation of the ScO2 threshold which varies between 15 and 25% according to the studies. Age is the main risk of OCDD. The management of this pathology should be early to avoid loss of autonomy of the patient. Finding a relationship, if it exists, would therefore significantly improve the mortality and morbidity of the said patient.
Interventions
Evaluate the relationship between oxygen saturation and the incidence of postoperative cognitive dysfunction in non-cardiac, thoracic and vascular emergency surgery in patients 65 years of age and older. The occurrence of POCD will be defined by the MMSE decrease of at least 4 points at 24, 48 or 72 hours
