Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: To investigate whether increased dose of local anesthetic (lidocain) increases duration of peripheral nerve block (adductor canal block);Secondary Objective: To develop a model for assessing duration of peripheral nerve blockades;Primary end point(s): Difference in duration of sensory block between different doses of lidocain assessed with pinprick.;Timepoint(s) of evaluation of this end point: Duration is defined as the time from block performance until recovery of sensation to pin-prick stimulus, assessed at 30 and 60 minutes post block, and thereafter every hour. | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): Difference in duration of sensory block between different doses of lidocain assessed with: - heat pain detection threshold - warmth detection threshold - pain during 1 minute of warmth stimulation - tolerance to transcutane electrical stimulation - cold sensation Difference in duration of motor block between different doses of lidocain assessed as maximum voluntary isometric contraction. Difference in onset of sensory blockade between different doses of lidocain, assessed with pinprick.;Timepoint(s) of evaluation of this end point: Duration is defined as time from block performance until recovery of normal sensation/ muscle strength, assessed at 30 and 60 minutes post block, and thereafter every hour. Onset is defined as the time from block performance until loss of sensation to pin-prick stimulus assessed at 30 and 60 minutes post block, and thereafter every hour. | — |
