Brief Summary

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

To compare the impact of pericapsular nerve group (PENG) block to intrathecal morphine on postoperative analgesia, motor function and side effects in patients undergoing primary total hip arthroplasty under spinal anesthesia.

Detailed Description

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

The study aims to confirm the non-inferiority of PENG block vs intrathecal morphine in patients undergoing total hip arthroplasty under spinal anesthesia. Non-inferiority will be assessed regarding maximum pain on a numerical rating scale at rest and during active hip flexion and regarding cumulative morphine consumption during 48 postoperative hours. Impact on quadriceps muscle motor function and side effects including pruritus, nausea and vomiting and hypotension will also be assessed.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

PENG block

Patients scheduled for primary total hip arthroplasty after receiving spinal anesthesia will undergo pericapsular nerve group (PENG) block.

Postoperative multimodal analgesia with paracetamol, etoricoxib and oxycodone

Group Type ACTIVE_COMPARATOR

Pericapsular nerve group (PENG) block

Intervention Type PROCEDURE

A 22 gauge 120mm nerve block needle will be introduced under ultrasound guidance in plane from superolateral to posteromedial to position the needle tip posterolateral to the ileopsoas tendon in-between the anterior inferior iliac spine and the ileopubic (ileopectineal) eminence and 20ml 0.5% levobupivacaine with 2mg (0.5ml) dexamethasone injected (total volume of injectate 20.5ml) between the tendon and the inferior pubic ramus just proximal to the attachment of the anterior hip capsule

Spinal anesthesia

Intervention Type PROCEDURE

Spinal anesthesia will be performed at the level of the presumed interspace in-between the third and fourth lumbar vertebrae by introducing a 27 gauge pencil-point spinal needle and 15mg of levobupivacaine (3ml) injected intrathecally

Intrathecal placebo

Intervention Type DRUG

0.5ml of placebo solution (0.9%NaCl) is added to the local anesthetic solution injected for spinal anesthesia (total injectate volume 3.5ml)

Intrathecal morphine

Patients scheduled for primary total hip arthroplasty will receive spinal anesthesia with local anesthetic and morphine administered intrathecally. After onset of spinal anesthesia a sham PENG block will be performed.

Postoperative multimodal analgesia with paracetamol, etoricoxib and oxycodone.

Group Type ACTIVE_COMPARATOR

Spinal anesthesia

Intervention Type PROCEDURE

Spinal anesthesia will be performed at the level of the presumed interspace in-between the third and fourth lumbar vertebrae by introducing a 27 gauge pencil-point spinal needle and 15mg of levobupivacaine (3ml) injected intrathecally

Intrathecal morphine

Intervention Type DRUG

100 micrograms of preservative free morphine diluted to a volume of 0.5ml is added to the local anesthetic solution injected for spinal anesthesia (total injectate volume 3.5ml)

Sham PENG block

Intervention Type PROCEDURE

A 22 gauge 120mm nerve block needle will be introduced under ultrasound guidance in plane from superolateral to posteromedial to position the needle tip posterolateral to the ileopsoas tendon in-between the anterior inferior iliac spine and the ileopubic (ileopectineal) eminence and a placebo solution consisting of 20.5ml 0.9%NaCl injected between the tendon and the inferior pubic ramus just proximal to the attachment of the anterior hip capsule
