Quality of Recovery After Hip Fracture Surgery: Ultrasound-guided Pericapsular Nerve Group Block Versus Fascia Iliaca Compartment Block

Participants were randomly divided into two groups : group PENG and group FICB, to receive either ultrasound-guided pericapsular nerve group block or fascia iliaca compartment block, using 50 ml of 0.2% ropivacaine.

For the FICB, a linear ultrasound probe was placed in the transverse plane and start scanning at the level of the inguinal crease to identify the femoral artery medially and the femoral nerve lateral to the femoral artery. The iliopsoas muscle should be seen overlying fascia iliaca. The block should be performed proximal to the arterial bifurcation. A 50 mm needle was introduced using an in-plane approach to penetrate the fascia iliaca. The hydro dissection separate the fascia iliaca from the iliac muscle, and a total volume of 20 ml of 0.2% ropivacaine was injected in this created space.

The PENG bloc is performed with a low frequency curvilinear ultrasound probe, which was initially placed in a transverse plane over the antero inferior iliac spine and the aligned with the pubic ramus by rotating the probe counterclockwise approximately 45 degrees. In this view, it is possible to observe the iliopubic eminence, the iliopsoas muscle tendon, the femoral artery and the pectineus muscle. A 100 mm needle was inserted from lateral to medial in an in-plane approach to place the tip in the musculofascial plane between the psoas tendon anteriorly and the pubic ramus posteriorly. Negative aspiration should be observed before injection of local anaesthetic and a total volume of 20 ml of 0.2% ropivacaine was injected.

Spinal anesthesia was performed after 20 minutes.

QoR-15 score was assessed before the intervention and 24 hours postoperatively.
