About this study

The aim of the Study is to compare the analgesic efficacy and clinical outcomes of suprainguinal fascia iliaca block (SIFIB) alone versus SIFIB combined with sciatic nerve block (SNB) in patients undergoing hip surgery.

  • Primary Objectives:

Time for first rescue analgesia.

  • Secondary Objectives:
  • Numerical Rating Scale (NRS) scores at rest and during movement at 6 hours, 12 hours, 24 hours, and 48 hours after surgery.
  • Total opioid consumption within the first 24 hours post-surgery.
  • Postoperative incidence and severity of motor blockade in the affected limb associated with each block technique (measured using the Modified Bromage Scale).
  • Technical difficulty and duration of administering each block.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Age: 18 - 70 years old.
  • Sex: Both sexes.
  • American Society of Anesthesiologists (ASA) physical status I , II, III, IV.
  • Hip surgeries e.g.: Total hip arthroplasty, Hemi-arthroplasty, Fracture neck of femur under spinal anesthesia

Exclusion criteria

  • Refusal to participate.
  • Known allergy to local anesthetics.
  • Coagulopathy or anticoagulant therapy contraindicating regional anesthesia.
  • Pre-existing neurological deficits in the lower limbs.
  • Infection at the injection site.
  • Severe cognitive impairment or inability to assess pain (e.g., advanced dementia).
  • Failed spinal anesthesia.
  • Body mass index (BMI) >40 kg / m²

Treatment and study plan

Bupivacaine Injection

Drug

Bupivacaine injection

Primary outcomes

  1. Time for first rescue analgesia

    Time frame: Numerical Pain Score in PACU, 6 hrs, 12 hrs, 24 hrs and 48 hrs postoperative

    Time to first request for rescue analgesia: Defined as the time interval from the end of procedure until the patient's first complaint of pain with a Numerical Rating Scale (NRS) score ≥ 4 and requests pain relief

Secondary outcomes

  1. Motor Block Assessment

    Time frame: The Modified Bromage Scale at 2 , 6 , 12 and 24 hours postoperatively

    Motor Block Assessment: Assessed using the Modified Bromage Scale (0 = no block; 1 = unable to raise extended leg; 2 = unable to flex knee; 3 = unable to move foot or knee) at 2, 6, 12, and 24 hours postoperatively
