Periarticular Infiltration of Local Anesthetics Versus Pericapsular Nerve Group Block for Total Hip Replacement

NCT05087862 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 60

No results posted yet for this study

Summary

This randomized trial is set out to compare the postoperative strength preservation capacity of local infiltration anesthesia (LIA) and pericapsular nerve group (PENG) block after performing a primary total hip arthroplasty (THA).

The hypothesis is that LIA represents a superior alternative to PENG block in terms of strength preservation but providing effective analgesia during the first 24 postoperative hours after THA. Hence, the trial was designed as a superiority study hypothesizing a fivefold reduction in quadriceps paresis/paralysis at 3 hours.

Interventions

PROCEDURE

Ultrasound-guided pericapsular nerves group of the hip block

After the ultrasound-guided insertion of a block needle at the level of the inguinal ligament, the needle will be advance into the plane between the iliac bone periosteum and the tendon of the iliopsoas muscle in order to inject 20 mL of adrenalized 0.5% bupivacaine.

PROCEDURE

Pericapsular local anesthetic infiltration of the hip

Intraoperatively, 60 mL of adrenalized 0.25% bupivacaine plus ketorolac 30 mg will be infiltrated by the surgeon.
