Cerebral Oxygenation and Spinal Anaesthesia in Elderly Patients With Hip Fracture

The aim of this study is to observe how the hemodynamic changes induced by spinal blockade affect cerebral oxygenation. Elderly patients are very frail. Hypotension is very frequent during spinal anaesthesia. Bradycardia is other side effect of regional anaesthesia affecting cardiac output and cerebral blood flow. These complications of spinal anaesthesia could decline cognitive function. In this way a non invasive monitoring technique as cerebral oximetry is useful for the safety of anesthetic procedure.
