Summary
This study is developed to determine if the local anaesthetic dose can be reduced by the use
of intermittent bolus technique compared to continuous infusion when the nerve catheter is
placed underneath the paraneurium by ultrasound guidance in the popliteal fossa. Our primary
outcome is local anesthetic use the first 48 hours after connecting the peripheral nerve
catheter. Our hypothesis is that with an intermittent bolus less local anaesthetic is
necessary the first postoperative 48 hours after surgery for adequate postoperative
analgesia. As secondary outcomes the investigators study pain scores, motor block, sensory
block, feeling of numbness, patient satisfaction, sleep quality and rescue analgesia during
the nerve block and afterwards.
