PENG Block Compared with Femoral Nerve Block for Spinal Anesthesia in Hip Fracture Surgery

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This prospective randomized study compares two ultrasound-guided nerve blocks used before spinal anesthesia for proximal femur fractures in adults aged 50 and older. The aim is to see if the PENG block provides better pain control and easier positioning for spinal anesthesia than the traditional femoral nerve block. All participants receive spinal anesthesia with bupivacaine, and the trial evaluates technical performance, pain, and hemodynamic stability during the perioperative period. The study targets improving comfort and efficiency of the anesthesia process in elderly patients at risk for painful positioning and hemodynamic fluctuations.

Inclusion Criteria:

* Adults aged 50 years or older.
* Diagnosis of proximal femoral fracture.
* Scheduled to undergo surgical repair under spinal anesthesia.
* American Society of Anesthesiologists (ASA) physical status I-III.
* Able to provide written informed consent.

Exclusion Criteria:

* Refusal to participate or inability to provide informed consent.
* Coagulopathy or contraindication to spinal anesthesia or peripheral nerve block.
* Local infection at the planned injection site.
* Known allergy or hypersensitivity to local anesthetics.
* Pre-existing neurological disease affecting lower extremity function or sensory assessment.
* Cognitive impairment preventing reliable study participation or outcome assessment.
* Previous lumbar spine surgery.
* Polytrauma.
* Body mass index (BMI) \<18 kg/m² or \>40 kg/m².
