Summary

This study will be a single-centre, assessor-blind, randomised controlled trial to compare the efficacy of the psoas sheath block (experimental group) with the suprainguinal fascia iliaca plane block (control group) in patients undergoing total hip arthroplasty

Participants will be randomly assigned to one of two groups (psoas sheath block or Fascia Iliaca block) using a computer-generated random number sequence. The allocation will be concealed in opaque, sealed envelopes.

The assessor will be blinded to the group allocation to ensure unbiased outcome assessment

Conditions

  • Total Hip Arthroplasty (THA)

Interventions

PROCEDURE

Psoas Sheath Block

Intervention group: Subpsoas Fascial Plane Block Participants in the subpsoas fascial plane block arm will receive a psoas sheath block preoperatively under direct ultrasound guidance as follows: Preparation: Standard skin sterilisation, prepping, and draping will be applied to the block area. Ultrasound Guidance: Anatomical landmarks will be identified using a curvilinear low-frequency (2-5 MHz) ultrasound probe. Local Anaesthetic Administration: A 22 G, 100mm needle will be inserted using the in-plane technique and advanced to the target site. A bolus of 40 ml of 0.375% ropivacaine will be injected into the subpsoas fascial plane. The procedure will be performed by experienced anaesthesiologists to ensure accuracy and safety

PROCEDURE

Suprainguinal Fascia Iliaca

Fascia Iliaca Compartment Block Participants in the fascia iliaca compartment block arm will receive a fascia iliaca block preoperatively under direct ultrasound guidance as follows: Preparation: Standard skin sterilisation, prepping, and draping will be applied to the block area. Ultrasound Guidance: Anatomical landmarks will be identified using a linear high-frequency (6-13 MHz) ultrasound probe. Local Anaesthetic Administration: A 22 G, 50 mm needle will be inserted using the in-plane technique and advanced beneath the fascia iliaca. A bolus of 40 ml of 0.375% ropivacaine will be injected into the fascia iliaca compartment. The procedure will be performed by experienced anaesthesiologists to ensure accuracy and safety. Dose adjustments will be made if the patient weighs \<50kg to reduce the risk of local anaesthetic systemic toxicity.
