Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of this clinical trial is to compare the analgesic effect of a pericapsular nerve group (PENG) block with a combined femoral, sciatic, lateral femoral cutaneous nerve block for postoperative analgesia in patients scheduled for secondary total hip arthroplasty. The primary objective of this study is to compare postoperative pain management between the PENG block and the combined block (femoral, sciatic, lateral femoral cutaneous) by measuring postoperative morphine consumption in each of the two groups.

Participants will be randomized into two groups. Patients assigned to the PENG group will receive a PENG block with ropivacaine, followed by a sham (sciatic) block, and spinal anesthesia with isobaric bupivacaine. Patients assigned to the combined block group will receive femoral, sciatic, lateral femoral cutaneous nerve blocks with ropivacaine, followed by spinal anesthesia with isobaric bupivacaine.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a single-center, prospective, superiority, randomized, double-blind, parallel-group study.

Patients will be randomized into two groups of 25 patients each, for a total enrollment plan of 50 patients. After written informed consent, patients will be allocated to one of the two groups according to a computer-generated randomization list.

The nerve blocks will be performed using ultrasound guidance.

During the surgery, 0.15 mg/kg of dexamethasone IV, 1 g paracetamol IV, 30 mg ketorolac IV, and 40 mg/kg magnesium IV will be given for postoperative analgesia.

In the PACU, pain management will be provided as needed with 2 mg of IV morphine at ten-minute intervals for pain scores \>4. Once spinal motor block has resolved, the patients will be transferred to the surgical ward with a morphine patient-controlled analgesia (PCA) pump. The pump parameters will allow 2 mg boluses of morphine with a 10-minute lockout and a maximum dose of 40 mg in 4 hours.

Basal analgesia will be provided with paracetamol (1 g/6 h) and ibuprofen (400 mg/8 h). Ondansetron (4 mg IV) will be administered in case of nausea or vomiting.

A research assistant will conduct postoperative visits at 2 hours, 1 day, and 2 days postoperatively to record research data. Functional testing will be done on days 1 and 2 by physiotherapy personnel.

Study Groups

PENG group

Pericapsular nerve group block

Group Type EXPERIMENTAL

Pericapsular nerve group (PENG) block with 0.75% ropivacaine guided by ultrasound

Intervention Type DRUG

Participants in the PENG group will first receive a sham sciatic injection; the needle will be inserted into the subcutaneous tissue and 3 ml of 0.9% NaCl will be injected. They will then receive a PENG nerve block in the supine position. A low-frequency (2-5 MHz) curvilinear ultrasound probe (BK Ultrasound) will be used to identify the anterior inferior iliac spine, the pubic eminence, and the psoas tendon with its fascial plane. A 22-gauge, 50 mm needle (SonoPlex® Pajunk) will be inserted into the fascial plane to inject 20 ml of 0.75% ropivacaine (Fresenius Kabi).

Combined nerve block

Combined femoral, sciatic, lateral femoral cutaneous nerve block

Group Type ACTIVE_COMPARATOR

Femoral, sciatic and lateral femoral cutaneous nerve block with 0.375% ropivacaine

Intervention Type DRUG

Participants in the combined group will first receive a sciatic nerve block performed with the patient in a semi-prone position, the lower limb flexed at 90° (hip and knee), elevated with a cushion placed between the legs. A straight line will be drawn between the greater trochanter and the ischial tuberosity. The sciatic nerve is located approximately at the midpoint of this line. Under ultrasound guidance, the ischial tuberosity will be identified medially, the greater trochanter laterally, the gluteus maximus muscle superficially beneath the adipose tissue, and the quadratus femoris muscle in depth. A 22-gauge, 50 mm needle will then be inserted into the fascial plane to inject 20 ml of 0.375% ropivacaine. The patient is then placed supine for femoral and lateral femoral cutaneous nerve blocks. 15 ml of local anaesthetics will be injected around the femoral nerve and 5 around the lateral femoral cutaneous nerve.
