[Anesthesia in the elderly].

A growing number of old or very old patients benefits from a surgical procedure. Age is an independent risk factor of postoperative mortality and postoperative complications including cognitive dysfunction. The choice of anesthetic technique does not significantly modify this risk. Preventive strategies and preoperative procedures can be implemented. A multidisciplinary management involving all care providers around the patient is essential to reduce the risk of dependence after surgery which is higher in this population. Early postoperative rehabilitation is recommended in the elderly to improve the prognosis.
