DIPB vs SIFIB for pain control after total hip replacement

Comparison of the Effects of Deep Iliacus Plane Block (DIPB) and Suprainguinal Fascia Iliaca Block (SIFIB) on Postoperative Analgesia in Patients Undergoing Hip Surgery: A Randomized Controlled Study

Not applicable Interventional Sivas Numune Hospital · NCT07452120

This will test whether the Deep Iliacus Plane Block (DIPB) or the Suprainguinal Fascia Iliaca Block (SIFIB) gives better pain relief and less leg weakness for adults having elective total hip replacement.

What this trial studies

In this randomized, double-blind trial, 70 adults undergoing elective primary total hip arthroplasty under spinal anesthesia will be assigned to receive either a DIPB or a SIFIB at the end of surgery. Investigators will record postoperative pain scores, opioid consumption, motor block, and block-related complications over 48 hours. The primary aim is to determine whether DIPB provides superior or comparable analgesia with reduced motor blockade compared with SIFIB. Findings will help guide choice of regional analgesia to support earlier mobilization and safer recovery after hip replacement.

Who should consider this trial

Good fit: Adults (age ≥18) with ASA physical status I–III scheduled for elective primary total hip arthroplasty under spinal anesthesia who can provide informed consent are ideal candidates.

Not a fit: Patients with contraindications to regional anesthesia (such as coagulopathy, local infection), significant pre-existing lower limb neurological deficits, or inability to consent would not be eligible and are unlikely to benefit from participation.

Why it matters

Potential benefit: If successful, the results could provide better pain control with less motor weakness, helping patients mobilize sooner after hip replacement.

How similar studies have performed: SIFIB is widely used and effective for cutaneous analgesia after hip surgery, while DIPB is a newer technique with anatomical and preliminary clinical reports suggesting improved deep joint analgesia but limited randomized evidence.
