About

Prospective observational cohort comparing analgesic efficacy of suprainguinal fascia iliaca block (SFIB) vs pericapsular nerve group block combined with lateral femoral cutaneous nerve block (PENG+LFCN) in primary total hip arthroplasty under general anesthesia (n=48). Outcomes include VAS pain at rest and with movement at 3, 12, 24, 48 h; morphine use (0-3, 3-12, 12-24, 24-48 h; total 0-48 h); quadriceps strength at 6 and 24 h; physiotherapy participation at 24 and 48 h; and adverse events within 48 h.

Full description

Adults undergoing primary posterolateral THA under general anesthesia were included if they received either SFIB or PENG+LFCN. Pain (VAS at rest and with 45° passive flexion) was recorded at 3, 12, 24, and 48 h. Morphine via PCA was recorded for 0-3, 3-12, 12-24, and 24-48 h, with a 0-48 h total. Quadriceps strength (0-2 scale) was assessed at 6 and 24 h; physiotherapy participation at 24 and 48 h; opioid- or block-related adverse events through 48 h.

Trial design

48 participants in 2 patient groups

SFIB

Description:

Patients undergoing THA who received ultrasound-guided SFIB with 0.25% bupivacaine 40 mL under the fascia iliaca with cranial spread.

PENG

Description:

Patients undergoing THA who received ultrasound-guided PENG (0.5% bupivacaine 15 mL) at the iliopubic eminence plus LFCN block (0.5% bupivacaine 5 mL) distal to the inguinal ligament.
