Comparing Fascia Iliaca Compartment Block and Pericapsular Nerve Group Block for Hip Fracture Pain Control

"A linear ultrasound transducer is placed in a sagittal plane to identify the anterior superior iliac spine. By sliding the transducer medially, the fascia iliaca and abdominal internal oblique, sartorius, and iliopsoas muscles are identified. After identifying the bow-tie sign, a 23-gauge needle (7mm, Nipro, Japan) is inserted in plane from caudal to cephalad until the needle tip penetrate the fascia iliaca. After negative aspiration, 0.35% ropivacaine 30mL with 1:400,000 epinephrine will be injected to separate the fascia iliaca and the iliacus muscle."

A curvilinear ultrasound transducer is initially place on the anterior inferior iliac spine and then aligned to the iliopubic eminence by rotating around 45 degree. In this view, the iliopubic eminence, iliapsoas muscle and tendon, pectineus muscle, femoral artery and vein will be identified. A 23-gauge needle (7mm, Nipro, Japan) is inserted in plane from lateral to medial until the needle tip in the musculofascial plane between the psoas tendon anteriorly and the pubic ramus posteriorly. After negative aspiration, 0.35% ropivacaine 20mL with 1:400,000 epinephrine will be injected.
