Achtergrond van het onderzoek
The aim of this study is to investigate the efficacy and safety of nebulizing S-ketamine. Three different doses of nebulized S-ketamine will be administered. Arterial blood samples will be taken to measure pharmokinetic effect. The analgesic effect will be measured by two different pain tests (pressure and electrical test). Side effects will be evaluated by two questionnaires (Bowdle, and Bond&Lader)
Doel van het onderzoek
- Hypothesis#1 efficacy
We hypothesize that a quick onset, and a predictable dose-response, good adjustability of analgesia can be achieved with inhaled ketamine.
Hypothesis#2 safety
Inhalation of nebulized ketamine might lead to a fast onset of analgesia, with limited adverse events.
Onderzoeksopzet
Analgesia:before nebulization, 18, 30, 60 and 80 minutes
after start of nebulization, pain relief to pressure pain will be
studied
pharmacokinetics: arterial blood samples (3 ml per sample) for ketamine and norketamine will be taken before nebulization/iv infusion and at specific time points during and after inhalation and iv treatment.
- Hemodynamics: Continuous cardiopulmonary monitoring
-Side effects will be inquired before start of nebulization, just after and every 20 minutes after nebulization. Side
effects will be measured using visual analog scales ranging from 0 to 10 cm of the Bowdle and Bond &Lader questionnaires.
