Major complications after 400 continuous popliteal sciatic nerve blocks for post-operative analgesia.
In a randomised comparison of the classic posterior approach and the modified inter-tendinous popliteal sciatic nerve block, no difference in success rate was demonstrated (81% vs 71%), which is comparable to our results (2).
7) Neurostimulation guidance for popliteal sciatic nerve block may result in disappointing block success: 16%, 60.6%, 70% and 81.5% are reported by various authors (2,3,5).
Ultrasound guidance has been shown to enhance the quality of popliteal sciatic nerve block compared with single injection, nerve stimulator guided block (7).
The popliteal sciatic nerve block in the ultrasound group (US group) was performed as follows (by three anaesthesiologists with extensive experience with the ultrasound technique).
