NCT07153575

Brief Summary

The goal of this clinical trial is to compare the analgesic effectiveness of two blocks in hip arthroplasty. The main question it aims to answer is

  • Which block is more efficient? Researchers will compare the suprainguinal fascia iliaca block with the pericapsular nerve group block. Participants will be randomized, and one of the blocks will be applied.

Suprainguinal fascia iliaca block

ACTIVE COMPARATOR

The ultrasound-guided suprainguinal fascia iliaca block (SFIB) procedure was first described by Hebbard et al. in 2011. It is a prevalent regional anesthesia technique employed in surgical procedures involving the hip joint and femur. Local anesthetics are administered in close proximity to the fascia iliaca. The primary objective is to obstruct the femoral, obturator and lateral femoral cutaneous nerve in a simultaneous manner. In clinical practice, it is a safe and simple alternative to lumbar plexus blocks and femoral blocks. A 30-ml solution of 0.25% bupivacaine was injected between the iliac muscle and the iliac fascia. The bupivacaine dosage administered in the study was standardized for the groups by employing equal concentrations and volumes.

Procedure: suprainguinal fascia iliaca block

Pericapsular nerve group block

ACTIVE COMPARATOR

In pericapsular nerve group (PENG) block the local anesthetic agent is injected into the musculofascial plane between the psoas muscle tendon and the pubic ramus. The primary objective of this technique is to obstruct the articular branches of the femoral, obturator, and accessory obturator which innervate the hip capsule. Therefore, a comparison with the SFIB was undertaken. A 30-ml block of 0.25% bupivacaine solution was injected between the pubic ramus and the iliopsoas muscle tendon. The bupivacaine dosage administered in the study was standardized for the groups by employing equal concentrations and volumes.
