Suprainguinal Nerve Block
An 89 year old male presented after a mechanical fall onto his right hip. X-rays demonstrated a comminuted right intertrochanteric fracture.
An ultrasound-guided fascia iliaca block can be performed using the suprainguinal approach when placing the probe perpendicular to the inguinal ligament. The internal oblique (cephalad, blue) and the sartorius (caudad, red) muscles are encompassed by the fascia lata (green) superiorly and the fascia iliaca (yellow) inferiorly. These two come together to form a “bow tie” as shown above, anesthetic is deposited below the fascia iliaca. Studies have shown improved analgesia with the suprainguinal, as it is believed to have a higher likelihood of blocking the lateral femoral cutaneous nerve and the obturator nerve.

Ulnar Nerve Block
Ulnar nerve block done in plane. Provides excellent anesthetic for isolated hand injuries. In this case, allowed for faster time to repair and avoided use of ketamine sedation. Inject in place and use small amounts of lidocaine to make sure you are in the correct space before bathing the nerve with the entire amount of anesthetic.

Median Nerve
The median nerve is the most echogenic of the upper extremity nerves. It is also the only forearm nerve that that does not run alongside vessels, making it an easy and safe target for a nerve block. It is seen here as a hyperechoic, honeycomb appearing oval in the center of the screen. The probe is positioned in transverse orientation on the volar aspect of the forearm.

Radial Nerve
The radial nerve is the least echogenic of the upper extremity nerves, and can be difficult to visualize. It is located lateral (radial) to the radial artery. It is best seen by following the radial artery in transverse proximally up the arm; eventually a bright hyperechoic oval will be visible traveling away from the artery. (right arm seen here)

Popliteal Sciatic Nerve Block
Popliteal Sciatic Nerve Block
A 71 year old woman with dementia and mobility constraints presented with a gaping laceration over the posterior gastrocnemius extending inferiorly towards the achilles after a “fall from wheelchair”. Achilles tendon function was preserved and the wound was explored without foreign body. The patient did not tolerate initial attempts at laceration repair after local anesthesia due to pain and anxiety.
A decision was made to perform a popliteal sciatic nerve block.
The patient was placed in the prone position and 1% lidocaine without epi was drawn up in a syringe with extension tubing connected to a spinal needle under sterile conditions. A linear probe was used to identify the sciatic nerve just below the adductor magnus muscle. Lidocaine was injected 1 cm distal to the sciatic nerve’s bifurcation into the Common Peroneal N. and Tibial N. using the “in-plane” view. 20mL spread above, below and around the sciatic nerve sheath was sufficient to provide near-complete anesthesia and the patient tolerated the entire laceration repair.

Superficial Cervical Plexus Block
The superficial cervical plexus block pictured above was utilized in an elderly awake patient with dementia for the placement of an IJ CVC. Other indications include I&Ds of submandibular abscesses, lac repair to the ear lobe, and clavicular fractures. The block is best performed in-plane so as to directly visualize the dissection of the plane between the Sternocleidomastoid muscle (visualized superiorly) and the scalene muscles (visualized inferior to the needle insertion), and works by bathing several nerve branches at once. The area of anesthetic overlies the sternocleidomastoid muscle from the clavicle up to the preauricular space and oddly enough, includes the earlobe.

Posterior Tibial Nerve Block
A 20s y/o patient presented after a laceration to the plantar surface of the foot from glass. After exclusion of retained foreign body by XR and physical exam, the laceration was irrigated and repaired using local infiltration of anesthesia, and the patient was discharged. The patient re-presented to the ED within a few hours with continued pain. The laceration repair was intact, and a posterior tibial nerve block was performed for analgesia. This clip shows the nerve block being performed. The linear probe was placed in a transverse plane, just posterior to the medial malleolus, over the “tarsal tunnel.” The left of this image is anterior, and the right is posterior. The needle (^) can be seen entering from the posterior aspect, infiltrating anesthetic around the tibial nerve (*). The pulsating posterior tibial artery is seen anterior to the nerve.
The anatomy of the tarsal tunnel can be recalled by the mnemonic “Tom, Dick, And Very Nervous Harry,” which lists the structures in order of anterior to posterior (tibialis posterior tendon, flexor digitorum longus tendon, posterior tibial artery, posterior tibial vein, tibial nerve, flexor hallucis longus tendon), however the tendons and posterior tibial vein are less well seen in this clip.

Supraclavicular Brachial Plexus Block
40s M presented with shoulder pain after a fall at work, and radiographs confirmed a proximal humerus fracture. As the patient was neurovascularly intact and had a closed fracture, conservative management in a sling was planned by orthopedic surgery. To augment pain control, a supraclavicular brachial plexus block was performed using bupivacaine and dexamethasone. The block is shown here, with color doppler first used to identify the carotid artery and confirm the absence of vascular flow in the region of the brachial plexus. The supraclavicular brachial plexus is seen at the center right of the image, just lateral and adjacent to the pulsating carotid artery with color flow. The first rib is seen just deep to the artery and plexus, providing a physical backstop to avoid inadvertent pneumothorax. An in-plane technique was used to advance the needle and anesthetic was deposited just superficial to the brachial plexus. The patient had improvement of his pain and was able to be discharged with outpatient orthopedic follow up.

Popliteal Sciatic Nerve Block for Lac Repair
30s F presented with multiple self inflicted lacerations to the leg. To facilitate laceration repair without using a near toxic dose of lidocaine, a popliteal sciatic nerve block was performed. The block is shown here with the needle approaching from the lateral aspect of the popliteal fossa, in plane with the probe, depositing anesthetic next to the popliteal nerve (*). The anesthetic in this clip is outside of Vloka’s sheath, which encompasses the sciatic nerve and its more distal branches, the common peroneal and tibial nerves. Accordingly, onset of anesthesia in this patient was delayed, and so the laceration repair was completed using a combination of local infiltration of anesthetic as well as this nerve block.

Popping through the Fascia Iliaca
A 60s F presented with hip pain after a recent fall. Radiographs showed a subacute femoral neck fracture. To aid with pain control, a fascia iliaca compartment nerve block was performed. The needle is seen here popping through the fascia iliaca, just superficial to the iliacus muscle, before injecting anesthetic just below the fascia iliaca. This injection was somewhat intramuscular. The expansion of the anesthetic pocket with injection and collapse when injection is paused helps confirm that anesthetic is spreading along the fascial plane rather than pooling in a contained area within muscle.

Erector Spinae Block for Nephrolithiasis
30s M with PMH nephrolithiasis in the past presented with acute onset flank pain. POCUS demonstrated mild hydronephrosis, and his workup was not suggestive of renal insufficiency or UTI, so aggressive symptom control was pursued. He was still experiencing significant pain after two doses of IV morphine, so an erector spinae plane block was offered. After informed consent and setup of supplies, the block was performed and is shown here. The transducer was placed in a sagittal orientation on the mid back at the level of T9, just lateral of midline (toward the affected side) in order to visualize the transverse process. A clip is shown here highlighting the transverse process, and the probe slides laterally to show the more superficial ribs with sliding pleura visible deep to them. The erector spinae muscle can be seen in long axis, just superficial to the transverse process. A 4 inch 20g nerve block needle was advanced using in-plane guidance until the needle tip contacted the transverse process, just deep to the erector spinae muscle. After a negative aspiration for blood, 30 mL of 0.5% bupivacaine with epinephrine plus 1 mL of dexamethasone (4mg in 1 mL) was injected deep to the erector spinae muscle. The patient had improvement of his pain and was able to be discharged with outpatient PCP follow up.

Infraclavicular Brachial Plexus Nerve Block
A 71-year-old male presented to the ED one day after a ground level mechanical fall during which he sustained a L shoulder injury. Given his age and initial borderline blood pressures, he received CT images of his chest, abdomen and pelvis which initially revealed a minimally displaced humeral head fracture extending into the greater tuberosity. His workup was ultimately otherwise unremarkable. He was consented for an infraclavicular block for pain control prior to being placed in a cuff and collar sling.
The needle can be seen approaching the axillary artery, around which the lateral, posterior and medial cords of the brachial plexus lie anatomically. The needle approach is from cephalad to caudal, with the ultrasound probe placed in the deltopectoral groove. The goal of this block is to deposit anesthetic at the 6 o’clock position relative to the axillary artery. Anesthetic can be seen depositing just superior to the axillary artery, around the 7 o’clock position (screen right). A total of 20 cc of 0.25% bupivicaine with 4 mg of dexamethasone was used.
Prior to the block, the patient’s pain score was an 8 out of 10, with significant pain with passive or active range of motion. Shortly after the block, his pain decreased to a 2 and he started ranging his shoulder with minimal discomfort. He was placed in a sling and ultimately stayed in the observation unit for frequent falls and PT/OT evaluation.

Adductor Canal (Saphenous) Nerve Block
A 58-year-old woman presented to the ED two weeks after being bitten on her right thigh by her dog with a growing abscess over the medial thigh just superior to the knee. In order to facilitate abscess drainage, a combination of femoral nerve and adductor canal (saphenous) nerve blocks were performed. Seen here is the saphenous block. The transducer was placed over the middle third of the thigh on the medial aspect. The needle is seen approaching from lateral to medial with the femoral artery pulsating at the bottom of screen right. The adductor canal contains the saphenous nerve, the femoral artery and femoral vein. It lies just deep to the sartorius muscle, lateral to the vastus medialis and medial to the adductor longus muscle. 10 cc of 1% lidocaine without epinephrine can be seen hydrodissecting the fascial plane just deep to the sartorius muscle. The patient then underwent a pain free abscess drainage.

Erector Spinae Nerve Block
A 43-year-old female presented to the ED with four weeks of ongoing R sided costovertebral angle and anterior chest wall discomfort, previously having been treated for pyelonephritis at the onset of her pain. Given her nonspecific symptoms that had been refractory to standard management, a right sided erector spinae block was offered for analgesia. The needle can be seen approaching the T6 transverse process (the approximate site of her pain) from cephalad. The erector spinae muscle is lifted off the transverse process with good spread in the fascial plane demonstrated in the subsequent images. 30 cc of 0.33% bupivacaine with 10 mg of dexamethasone was used. The patient had moderate pain relief.

Ulnar Nerve Block
A 45-year-old male presented to the ED with an accidental self inflicted laceration to the hypothenar eminence of his R hand sustained from a pocket knife. He received an ulnar nerve block for pain control. The ulnar nerve can be seen separating from the ulnar artery as the probe is fanned up the medial aspect of the forearm. The needle can then be seen approaching the nerve from medial to lateral and approximately 5 cc of 2% lidocaine was deposited just lateral to the nerve. The patient then underwent a pain free laceration repair.

Erector Spinae Block for a Traumatic Injury
A 45-year-old male presented to the ED as a pedestrian struck by a car. He was hit from behind and pinned to a wall briefly. Workup revealed left sided 1st-5th anterior rib fractures, 3rd-7th posterior rib fractures with significant displacement, as well as left C7 and T1 transverse process fractures and a left medial clavicle fracture. An erector spinae block was performed for analgesia. In the first image, the erector spinae muscle layer can be seen sitting atop two levels of transverse processes. The patient was slowly rolled onto the right lateral decubitus. The second clip shows a needle approaching from cephalad and depositing anesthetic into the fascial plane between the erector spinae and transverse process. The patient felt near immediate pain relief at the termination of the procedure. He was subsequently brought to the SICU prior to having a rib plating operation the following day, and received a serratus anterior catheter placed by anesthesia during pre-op.

Transgluteal (Proximal) Sciatic Nerve Block
A 36-year-old male presented to the ED with acute onset left sided back pain that started suddenly 6 hours prior to arrival while bending over. The pain radiated down his left leg and he had a positive straight leg raise with a severely antalgic gait. A transgluteal sciatic nerve block was performed. The patient was positioned in the right lateral decubitus position with the left hip and knee flexed. The needle can be seen approaching from lateral to medial, just over the greater trochanter. The needle reaches the fascial plane between the gluteus maximus and quadratus femoris muscles where the sciatic nerve and inferior gluteal artery lie. The plane is seen separating with hydrodissection using 20 cc of 0.5% bupivacaine with 10 mg of dexamethasone. The patient had complete relief after the block and was able to ambulate out of the department with ease.

PENG Block
A PENG block was performed using the linear probe. The hyperechoic psoas tendon can be seen lifting off the ileum with the injection of anesthetic.
