PENG+LFCN Block vs QIPB for Total Hip Arthroplasty
Sponsor: Antalya City Hospital
Summary
This randomized clinical trial aims to evaluate and compare the analgesic efficacy and functional outcomes of the quadro-iliac plane block (QIPB) and the pericapsular nerve group (PENG) block combined with lateral femoral cutaneous nerve(LFCN) block in patients undergoing total hip arthroplasty. The primary outcome is the Numeric Rating Scale (NRS) within the first 48 hours after surgery. Secondary outcomes include postoperative total opioid consumption, ıncidence of quadriceps motor block, time to first ambulation, block performance time, falls, length of hospital stay, block- related complications(hematoma,local anesthetic systemic complications, vascular puncture, and infection), patient satisfaction assessed using a Likert scale, and incidence of postoperative nausea and vomiting.

Conditions
Interventions
Quadro iliac Plane Block(QİPB)
Participants allocated to the QIPB group will receive an ultrasound-guided quadro-iliac plane block after spinal anesthesia. Following standard aseptic preparation, 30 mL of 0.25% bupivacaine will be administered into the target fascial plane under ultrasound guidance after confirming the absence of blood on aspiration.
PENG Block and LFCN Blok
Participants in the PENG group will undergo an ultrasound-guided pericapsular nerve group (PENG) block after spinal anesthesia. A total of 20 mL of 0.25% bupivacaine will be administered.
Lateral femoral cutaneous nerve block(LFCN)
Participants in the LFCN group will undergo an ultrasound-guided lateral femoral cutaneous nerve block after spinal anesthesia. A total of 10 mL of 0.25% bupivacaine will be administered.
