Effect of desflurane, sevoflurane or propofol on the incidence of postoperative delirium in older adults undergoing moderate- to high-risk major non-cardiac surgery: study protocol for a prospective, randomised, observer-blinded, clinical trial (RAPID-II trial).

Introduction: The effect of different anaesthetics on the incidence of postoperative delirium is still not entirely clear. Therefore, we will evaluate the effect of desflurane versus sevoflurane versus propofol for the maintenance of anaesthesia on the incidence of postoperative delirium in older adults undergoing moderate- to high-risk major non-cardiac surgery. We will further compare the incidences of delayed neurocognitive recovery, long-term postoperative neurocognitive disorder, postoperative nausea and vomiting between the groups.

[Anesthesia for organ transplant patients].

Organ transplant patients who must undergo nontransplant surgical interventions can be challenging for the anesthesiologists in charge. On the one hand, it is important to carefully monitor the graft function in the perioperative period with respect to the occurrence of a possible rejection reaction. On the other hand, the ongoing immunosuppression may have to be adapted to the perioperative requirements in terms of the active substance and the route of administration, the resulting increased risk of infection and possible side effects (e.

[Anaesthesia and Perioperative Management for Patients with Parkinson's Disease].

Idiopathic Parkinson's syndrome is associated with the loss of dopaminergic cells. It is defined by the presence of akinesia together with one of the cardinal symptoms: rigor, tremor, or postural instability. As the perioperative management of these patients can be challenging and they have an increased perioperative risk, every anaesthesiologist should know some special features.
