What this trial studies

This study aims to evaluate the effectiveness of selective truncal blocks using varying doses and volumes of local anesthetic for anesthesia in patients undergoing surgeries of the hand, wrist, forearm, and elbow. The primary focus is on the onset times of motor and sensory blocks, with successful anesthesia defined as the completion of surgery under regional anesthesia. Secondary outcomes will assess motor block duration, analgesia duration, and potential complications associated with the procedure.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18-65 with ASA scores of 1-2 undergoing upper extremity orthopedic surgeries, excluding shoulder procedures.

Not a fit: Patients with severe pulmonary disease, uncontrolled diabetes, or those with allergies to local anesthetics may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could enhance pain management and reduce complications during upper limb surgeries.

How similar studies have performed: Previous studies have shown promising results with peripheral nerve blocks in upper extremity surgeries, indicating that this approach is supported by existing evidence.
