How To Perform A Popliteal Nerve Block

A popliteal sciatic nerve block done with the Sonosite SII ultrasound machine is a clinically valuable technique that results in anaesthesia of the calf, tibia, fibula, ankle, and foot. Anaesthesiologist Dr. David Auyong MD of Seattle, Washington here reviews scanning techniques and sonographic landmarks for the procedure, discussing important structures, techniques to visualise the popliteal vein, types of probe used, and needle/injection choices. The Sonosite II allows precise placement of local anaesthetic, much reducing patient discomfort, providing superior visualisation of the nerve and the needle during block placement.
