Primary
| Measure | Time frame |
|---|---|
| Main Objective: The objective of the trial is to place a supraclavicular catheter in 32 healthy volunteers and examine: 1: If the largest shoulder nerves are affected 2: which other nerves are affected after injection with a low (5ml) or a high (20 ml) volume of ropivacain 5 mg/ml.;Secondary Objective: Not applicable;Primary end point(s): Succesfull shoulder block (yes/no) defined as sensory affection of the axillary nerve combined with motor affection of the suprascapular nerve.;Timepoint(s) of evaluation of this end point: TB: Baseline measurement after placement of nerve catheter. T1: 45 minutes after injection of ropivacain. | — |
