Randomized Controlled Trial Clinical Trial
[Does intraoperative hyperventilation improve neurological functions of older patients after general anaesthesia?].
The purpose of the study was to investigate the effect of intraoperative hyperventilation on postoperative cognitive functions. ⋯ In older patients, POCD occurred more frequently after intraoperative normoventilation. We assume that a reduced amount of noxious substances reach the brain after hyperventilation, because hyperventilation reduces the cerebral blood flow.

Clinical Trial
[Patient evaluation of postoperative recovery. An evaluation of the QoR scores in 577 patients].
In 1999 Myles and co-workers presented their quality of recovery score (QoR score) as a tool to evaluate postoperative recovery and to measure patient satisfaction. It was developed according to predefined psychological standards and its reliability and validity had been proven in large clinical trials. The aim of this study was to evaluate a German version of the QoR in a heterogeneous group of surgical patients. ⋯ The German translation of the QoR score is easily applicable to a heterogeneous surgical population and thus can be used as a valuable measure of quality of anaesthesia care and patient satisfaction.
