Arm Label
Ultrasound guided regional anesthesia
Local infiltration analgesia
Arm Description
Patient will be given a peripheral nerve block from their treating anesthesiologist before the operation (in the OR) with an conventional ultrasound guided femoral and sciatic block of each 15 ml ropivacaine 0,5% and 0,5 ml dexmedetomidine (100µg/ml).
Patient will be given a local infiltration analgesia from their treating surgeon during the operation (in the OR) with 60 ml ropivacaine 0,5% and 1 ml dexmedetomidine (100µg/ml).
Outcomes
Primary Outcome Measures
Need of opioid consumption in oral morphine equivalent
consumed opioids in mg of oral morphine equivalent
Secondary Outcome Measures
Pain assesment
Pain experienced by patients according to self-assesment according to NRS (Numeric rating scale) (minimum 0, maximum 10) (higher score means worse outcome)
Pain medication necessary
Need of opioid consumption in mg of oral morphine equivalent up to the 5th postoperative day
Functionality of the prothesis - OKS (Oxford Knee Score)
According to physical examination by the Oxford Knee Score (minimum 0, maximum 48) (higher score means better outcome)
Functionality of the prothesis- KOOS (Knee Injury and Osteoarthritis Outcome Score)
According to physical examination by the orthopedics score KOOS (minimum 0, maximum 100) (higher score means better outcome)
Functionality of the prothesis - WOMAC (Western Ontario and McMaster Universities Osteoarthritis Index)
According to physical examination by the orthopedics score WOMAC (minimum 0, maximum 96) (higher score means worse outcome)
Functionality of the prothesis- G-FJS (German Forgotten Joint Score)
According to physical examination by the orthopedics score G-FJS (minimum 0, maximum 100) (higher score means better outcome)
Complications
Incidence of complications in total (e.g. delirium, allergic reactions, cardiopulmonary decompensation)
procedure specific time
time of the operation

5. Study Description
Brief Summary
Evaluation of the Impact of dexmedetomidine as an adjunct for local infiltrations analgesia and ultrasound-based regional anaesthesia as pain medication in regard to patients' opioid need the first 48 hours after the total knee replacement operation.
Detailed Description
Evaluation of the Impact of dexmedetomidine as an adjunct for local infiltrations analgesia and ultrasound-based regional anaesthesia as pain medication in regard to patients' opioid need the first 48 hours after the total knee replacement operation. Secondary objectives are: Pain assesment, Pain medication necessary, functionality of the prothesis, satisfaction, wellbeing, postoperative discomforts, complications (delirium, allergic reactions, cardiopulmonary decompensation), procedure specific time.
