Following negative aspiration, 10 ml of bupivacaine 0.25% with preservative-free clonidine 20mcg was deposited (Figure 1). A 22-gauge 80 mm echogenic needle was advanced in-plane, deep to the popliteal artery and above the joint capsule. The probe was then advanced cephalad until the shaft of the femur was visualized. With the patient in the same position, the probe was placed in the popliteal fossa identifying the popliteal artery and femoral condyles. A curvilinear, low-frequency transducer (2-5MHz) was used for the IPACK to maximize visualization. Following negative aspiration, 6ml of bupivacaine 0.25% with preservative-free clonidine 20mcg was deposited in the adductor canal. A 22-gauge 50 mm echogenic needle was advanced in-plane from the lateral to medial direction, deep to the sartorius and juxtaposed to the vastus medialis. A high-frequency linear ultrasound probe (15MHz) was placed transverse to the medial thigh, and rotated medially to visualize the adductor canal for ACB. Proceeding general anesthesia, the patient was positioned supine with the left lower extremity externally rotated and flexed 40 at the knee. He underwent arthroscopic assisted repair of the proximal tibial avulsion fracture. Imaging revealed left ACL avulsion from its tibial attachment, anterior-lateral meniscus tear and avulsion of the popliteofibular ligament. ![]() Herein we describe the utilization of the IPACK combined with an ACB for arthroscopic ACL repair in a pediatric patient.Ī 10-year old, 41kg, healthy male presented following a motor vehicle injury. The ultrasound-guided deposition of local anesthetic to the Interspace between the Popliteal Artery and The Posterior Knee Capsule (IPACK) in combination with blockade of the anterior knee with an ACB has gained significant interest for such surgery. However, its lack of posterior knee and anterolateral coverage makes it non-ideal as a sole agent. Widely used for knee surgery, the Adductor Canal Block (ACB) provides motor-sparing analgesia to the anteromedial knee and distal medial leg. ![]() Regional anesthesia has proven to reduce nociceptive pain and opioid requirements following ACL surgery, thereby facilitating earlier hospital discharge and improved patient satisfaction. Adult literature demonstrated daily opioid consumption of 35-45 mg morphine equivalents in the first 2 weeks after ACL reconstruction. Postoperative pain control after ACL reconstruction or repair usually involves opioids. Injuries to the ACL can result in ligament rupture or, less commonly, traumatic avulsion fracture at the ACL insertion site on the proximal tibia. Francis Hospital, Hartford, CT, USA.The incidence of Anterior Cruciate Ligament (ACL) reconstruction amongst pediatric patients has risen over the last decade. Sanjay K Sinha, Woodland Anesthesiology Associates in St. ![]() This technique was first described by Dr. The IPACK block is a muscle strength-sparing technique that consists of an infiltration of local anesthetic into the interspace between the popliteal artery and the posterior capsule of the knee meant to be used as an alternative analgesic supplement to the femoral or adductor canal blocks to cover the posterior knee pain. While the sciatic nerve block results in the best analgesia for the posterior aspect of the knee, motor weakness of the lower extremity preventing early rehabilitation and masking intraoperative common peroneal nerve (CPN) injury do not make it an ideal analgesic modality. What is the rationale for the IPACK block? This month’s addition to the NYSORA web application is the I nfiltration between the P opliteal artery and C apsule of the K nee or the IPACK block. In NYSORA we continue working to create new educational content that combines the latest evidence-based information with requests from NYSORA readers. Table of Contents New Addition: IPACK BLOCK!
