Comparison of the Efficacy of PENG Block in Combination With LFCN Block and Wound Infiltration

Postoperative Pain Management in Patients Undergoing Total Hip Arthroplasty: PENG Block in Combination With LFCN Block or Wound Infiltration?

The ultrasound-guided approach for the blockade of articular branches of femoral and obturator nerves, pericapsular nerve group (PENG) block, is an effective method for postoperative analgesia in hip surgeries.

The ultrasound-guided approach for the blockade of articular branches of femoral and obturator nerves, pericapsular nerve group (PENG) block, is an effective method for postoperative analgesia in hip surgeries. However, it fails to provide cutaneous analgesia on the anterolateral surgical incisional site. This study compares the effects of wound infiltration and lateral femoral nerve blocks in combination with PENG blocks for postoperative pain in patients undergoing total hip arthroplasty for coxarthrosis.

Inclusion Criteria:

• Coxarthrosis
• Total hip replacement
• Patients agreed to receive PENG block
• LFCN or wound infiltration performed combined with PENG blocks

Exclusion Criteria:

• Other kinds of hip surgeries
• Total hip replacement performed for other indications
• Patients refused to receive PENG block
