288. Comparison between nerve blocks at the knee (tibial and peroneal nerve blocks) and spinal anaesthesia in hallus valgus operation

Background: Peripheral nerve block has become popular because it provides excellent surgical anaesthesia and postoperative analgesia and constitutes the majority of practice for hand surgery in our hospital. Our study refers to comparative evidence about nerve blocks at the elbow via low dose concentration of ropivacaine 0.375% or levobupivacaine 0.25% in hand surgery, especially in high risk patients with comorbid conditions.
