S3
interscalene landmark
mark the sternal and clavicular heads of the SCM, cricoid cartilage and clavicle. Needle goes in interscalene groove at C6 posterior to calvicular head of the SCM and between An and Mid scalene
Infraclavicular landmark
coracoid process, needle insertion 2cm inferior and 2cm medial to coracoid
axillary
pulse of axillary artery, guide needle through artery and aspirate, go further (past the artery is radial) when you pull back it is median and ulnar
musculocutaenous
belly of coracobrachialis muscle, posterior to biceps
ulnar block
at elbow, between medial epicondyle and olecranon process, medial to ulnar artery
radial block
at elbow between brachioradialis and biceps,
median block
at elbow medial to brachial artery at pronator teres
femoral block
below inguinal ligament, lateral to fem artery at crease
sciatic block
classic posterior: line between greater trochanter aand PSIS, 4cm distal to midpoint
parasacral: line drawn between ischial tuberosity and PSIS, needle 6cm caudal to PSIS on line
subgluteal: greater trochanter and ischial tuberosity, 4cm caudal to midpoint
Popliteal block
posterior: popliteal fossa crease, lateral biceps femoris medial semitendinosus/membranosus, needle 8cm superior to crease at midpoint
lateral: vastus lateralis, biceps femoris and popliteal crease, needle 8cm above popliteal crease in groove
ankle block
saphenous - distal extremis of femoral nerve, medial surfac of tibial tuberosity at dorsomedial aspect of upper calf or at medial malleolus
deep peroneal - lateral to extensor hallucis longus tendon at 1-2 digit webspace
superficial peroneal - lateral to extensor digitorum longus tendon
posterior tibial - posterior to posterior tibial artery
sural - lateral malleolus posterior
lumbar plexus block
spinous process, needle 4cm lateral to midline at level of crest
IJV placement
between sternal and clavicular heads of SCM, lateral to carotid
femoral vein placement
medial to artery at crease
subclavian vein placement
midpoint of clavicle with needle directed toward suprasternal notch
trachea landmarks
begings at C6, C-shaped cartilaginous rings that are lateral and anterior, posterior trachea is longitudinal muscular layer
first carina landmark
T5
thoracic duct landmark
left side, C7, empties into jxn of the left subclav and left IJV below clavicle
cricothyroid membrane, cric landmark
incision through skin, cric membran between cric and thyroid cartilage, c6
C shaped (forms circle with skull) hematoma
epidural
moon shaped, follows shape of skull hematoma
subdural
external branch of SLN innervates what
cricothyroid muscle, motor nerve
internal branch of SLN innervates what
sensory to larynx above vocal cords
recurrent laryngeal
mixed sensory and motor, sensory innervatino to upper trachea and innervates all intrinsic laryngeal muscles except cricothyroid
