Sedation in digestive endoscopy: innovations for an old technique.

Patient complexity, along with duration, number and invasiveness of procedures, increase every year in digestive endoscopy; so deep sedation, analgesia or general anesthesia requests are rising. The need for a safe, flexible, low cost and high-profile service play a central role in drugs, devices and monitoring development. The patient's degree of comfort and anxiety are also critical.

Recurrent postoperative delirium in spinocerebellar ataxia type 2: a case report.
