Summary

Comparison between local anesthetic infiltration between the popliteal artery and the capsule of the knee (IPACK) versus adductor canal block (ACB) or sciatic nerve block (anterior approach) in combination with femoral nerve block for postoperative analgesia in major knee surgeries.

Conditions

  • Post Operative Pain

Interventions

PROCEDURE

IPACK block

the probe is applied to the popliteal fossa for identification of the popliteal artery and femur. Then, the probe is slid distally for revealing the two femoral condyles followed by proximal sliding of the probe until the humps of the femoral condyles disappeared and the flat metaphysis appeared. a spinal needle 22G x 3.5 inches is advanced from the lateral aspect and directed across the space between the popliteal artery and femur and once the needle reached the medial edge of the femur, nearly at the level of the popliteal artery, negative aspiration is confirmed and 20 ml of bupivacaine 0.25% is injected incrementally as the needle was withdrawn

PROCEDURE

adductor canal block

the transducer is placed anteromedially, approximately at the junction between the middle and distal third of the thigh or somewhat lower. The saphenous nerve block should be performed at the most distal level where the artery still lies immediately deep to the sartorius muscle, thus minimizing the amount of motor nerve block of the vastus medialis; an adductor canal nerve block is typically performed more proximally, around the mid-thigh level. The needle is inserted in-plane in a lateral-to-medial orientation and advanced toward the femoral artery. Once the needle tip is visualized anterior to the artery and after careful aspiration, 20 ml of bupivacaine 0.25% is injected incrementally as the needle was withdrawn

PROCEDURE

sciatic nerve block

patient in a supine position with the hip and knee on the operated side flexed and the leg externally rotated at approximately 45 degrees. The ultrasound transducer is first positioned perpendicular to the skin approximately 8 cm distal to the inguinal crease. The location is then scanned by sliding and tilting the transducer until a clear transverse image of the hyperechoic sciatic nerve located posterior and medial to the lesser trochanter is obtained. a spinal needle 22G x 3.5 inches is advanced parallel and in line with the ultrasound transducer while the sciatic nerve is kept in the middle of the screen. The needle is advanced slowly under real-time ultrasound guidance until it is near the nerve then negative aspiration is confirmed and 20 ml of bupivacaine 0.25% is injected incrementally as the needle was withdrawn
