The purpose of the study is to determine whether equal subanesthetic doses of racemic
ketamine is equally effective on females and males after surgical removal of third molars
Official title: Effect of Racemic Ketamine on Pain in Females and Males After Surgical Removal of Third Molars
Study design: Treatment, Randomized, Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor), Placebo Control, Parallel Assignment, Pharmacodynamics Study
Primary outcome: Sum pain NRS
Secondary outcome: Several subjective variables assessing psychotomimetic effects
Ketamine is assumed to be a NMDA receptor antagonist which provides analgesia from acute
postoperative pain(and other types of pain) subanesthetic doses. Gender differences in
ketamine analgesia are not known. This placebo-controlled,randomised, parallel group study
investigates the analgesic dose-response effect of ketamine in subanesthetic doses in female
and male patients following surgical removal of third molars.
Comparisons: Placebo and ketamine in females and males.
Minimum age: 20 Years.
Maximum age: 30 Years.
- Indication for removal of third molar
- Between 20 and 30 years of age
- ASA Class 1
- Psychiatric family (father/mother) or own anamnestic history
- Hypersensitivity towards NSAIDS or other rescue analgesics
- Verified or suspected pregnancy
- Lactating females
- Surgery lasting over 60 min
