Efficacy of ketamine as an adjuvant to local anaesthetics in ultrasound-guided popliteal nerve blocks for foot surgeries: A double-blind randomized control study

Abstract

Popliteal block is a distal block of the sciatic nerve, which in combination with a saphenous nerve block will provide regional anaesthesia and/or analgesia for foot and ankle surgery. Division of the sciatic nerve into its branches, the common peroneal nerve and the tibial nerve, typically takes place around 6.5 cm above the popliteal crease. A catheter can be inserted to prolong the duration of analgesia. An online test is available for self-directed Continuous Medical Education (CME). It is estimated to take 1 hour to complete. Please record time spent and report this to your accrediting body if you wish to claim CME points. A certificate will be awarded upon passing the test. Please refer to the accreditation policy here.
