Study: NCT06282666

Intervention type: PROCEDURE
Group type: EXPERIMENTAL
Intervention: Spinal anesthesia
Description: Before the beginning of surgery, all patients will be anesthetized with 0.5 % hyperbaric bupivacaine (Marcaine Heavy), 1.5 - 2.5 mL solution. A pencil point spinal needle will be used.

Intervention type: PROCEDURE
Group type: EXPERIMENTAL
Intervention: lumbar erector spinae plane block
Description: Investigators will perform the lumbar ESPB under ultrasound control at the L3 level on the ipsilateral site of the surgery. After dissection with 0.9 NaCl, we will leave a catheter in the ESP. Then, we used 0.25% bupivacaine with epinephrine (5mcg/mL), 0.4 mL per kg, up to 40 mL.

Intervention type: PROCEDURE
Group type: EXPERIMENTAL
Intervention: Epidural analgesia
Description: After identifying the epidural space and spinal anesthesia (combined technique), a catheter will be placed in the epidural space. Investigators will give an epidural catheter a test dose of 2% lidocaine (2 mL). At the end of the surgery, the patient will receive 5 mL of a mixture containing 0.1% bupivacaine with fentanyl (2 mcg/mL).

Intervention type: PROCEDURE
Group type: EXPERIMENTAL
Intervention: patient-controlled analgesia
Description: Each participant will receive a pump with oxycodone (1mg/ml) using a patient-controlled analgesia (PCA) technique, a bolus of 1 mL, and a lockout of 5 minutes for the first postoperative day.

Intervention type: DIAGNOSTIC_TEST
Group type: EXPERIMENTAL
Intervention: Timed Up and Go test
Description: Investigators will measure the time the patient took to rise from a chair, walk three meters, turn around 180 degrees, walk back to the chair, and sit down while rotating 180 degrees. We will assess the patient before the surgery and 24 and 48 hours after hip replacement.

Group type: EXPERIMENTAL
Intervention: neuropathic pain symptom inventory
Description: The Neuropathic Pain Symptom Inventory (0-100; 0 denotes no pain, 100 the most severe pain) will be evaluated before the surgery and three and six months following the procedure.
