Introduction: According to the contemporary exigencies to reduce costs, day-surgery is surely destinated to spread more and more. Objective: The aim of this study is to demonstrate that stabilometric test could be the right choice. Methods: All the patients have been submitted to general anaesthesia induced with several drugs. Before and after anaestesia, the vestibulospinal system was evaluated using a stabilometric method. Results: After general anaesthesia, the stabilometric parameters showed a moderate to high alteration that was strengthened upon eye closure. Conclusions: The authors underline the importance to standardize a test to allow the discharge of patients who have been operated in general anaesthesia for selected pathologies, during the same day.
