What this trial studies
This prospective, randomized, observer-blind study aims to compare the effectiveness of two injection techniques—subparaneural and interneural—in performing popliteal sciatic nerve blocks for patients undergoing foot, ankle, or toe amputation. Participants will be ASA III or IV risk group adults aged 18 and older. The study will assess sensory and motor blockage at regular intervals following local anesthetic injection, documenting various block characteristics and any complications that arise. The goal is to determine which method provides better anesthesia outcomes.
Who should consider this trial
Good fit: Ideal candidates are adults aged 18 and older with ASA III or IV status who are scheduled for foot, ankle, or toe amputation.
Not a fit: Patients with neurological or psychiatric diseases, chronic pain requiring opioids, or those allergic to local anesthetics may not benefit from this study.
Why it matters
Potential benefit: If successful, this study could lead to improved pain management and reduced complications for patients undergoing foot and ankle surgeries.
How similar studies have performed: Other studies have shown varying success with similar nerve block techniques, but this specific comparison is novel.
