In a fMRI experiment, will measure the changes in brain activity patterns and in functional connectivity. We hypothesize that a subanesthetic dose of S-Ketamine impairs the functional connectivity, especially the feedback connections that are…
Primary aim:The primary aim of this study is to evaluate the effect of two consecutive infusions of S(+)-ketamine in patients with CRPS-I on pain relief. The design of the study is prospective, randomised, double-blind and placebo-controlled.…
1. Measure DNIC and offset analgesia in CRPS-1 patients, fibromyalgia patients and neuropathic pain patients;2. Compare DNIC and offset analgesia in chronic pain patients with DNIC and offset analgesia in healthy volunteers;3. Assess the effect of…
1. To quantify the influence of propofol on the distribution, redistribution and elimination of ketamine and to evaluate the importance of hemodynamic parameters on the pharmacokinetics of ketamine.2. To quantify the influence of ketamine on the…
By means of resting state network measurments using fMRI we hope to gain more knowlegde about the actions (for example as an analgesic) an side effects of S(+)-ketamine on the central nervous system at different doses. Also blood samples will be…
The objectives are to assess the pharmacokinetic and pharmacodynamic effects of sub-anesthetic ketamine administration, to assess the optimal dose of ketamine and gender differences, to compare different oucome measures for psychomimetic symptoms…
