Anesthesia Key

   The important landmarks for this block include the inguinal crease and femoral artery (FA).    An anatomic study has shown the femoral nerve (FN) to be widest and most superficial at…

   The course of the axillary artery is palpated and marked in the proximal axilla.    The expected location of the median nerve is superficial and lateral to the artery with the…

   Important surface landmarks to identify include the most cephalad portions of the medial malleolus (MM), lateral malleolus (LM), and the Achilles tendon posteriorly. The sural nerve is located in the…

   The borders of the Triangle of Petit serve as the major surface anatomic landmarks: the iliac crest inferiorly, the external oblique (EO) muscle anteriorly, and the latissimus dorsi muscle posteriorly….

   After identification of this landmark, a point is marked 2 cm medial and 2 cm caudad to the most anterior tip of the coracoid process. A. View of right shoulder…

   Landmarks for the ultrasound-guided subgluteal sciatic nerve block include the greater trochanter (GT) laterally and ischial tuberosity (IT) medially. Caudad to the gluteal crease, the sciatic nerve lies along the…

   The popliteal crease is identified and marked while the patient flexes the knee. The medial and lateral borders of popliteal fossa are formed by semimembranosus and biceps femoris tendons. The…

   Important surface landmarks include the sternocleidomastoid (SCM) and clavicle. The SCM may be identified by asking the patient to turn the head away from the affected side and flex the…

   A line should be drawn along the posterior border of the SCM. The cricoid cartilage should be identified and a line drawn along a skin crease at this level to…

   Draw the intercrestal line between the tops of the iliac crests which intersects the midline at a 90 degree angle. A third line parallel to midline is marked through the…
