Abstract
Patients with severe aortic stenosis, whether symptomatic or not possess unique challenge to the anaesthetist . Both general anaesthesia and regional anaesthesia with central neuraxial blockade carry potential risks owing to a fixed cardiac output. Haemodynamic fluctuations associated with anaesthesia can be detrimental in these patients. They are at increased risk for intraoperative and post- operative complications given the severity of aortic stenosis. A clear intraoperative plan should be designed to manage the unique haemodynamics of these patients. We report a case of assymptomatic severe aortic stenosis posted for an urgent lower limb surgery. Ultra sound guided combined popliteal-sciatic and femoral nerve blocks were used as a sole anaesthetic technique. Patient was haemodynamically stable in the intra-operative as well as post operative period. Patient did not require any additional analgesic for about 10 hours post-operatively.
