Abstract
Background: Regional anesthesia is widely used for perioperative pain management. The introduction of ultrasound guidance has significantly improved the precision of nerve localization, potentially enhancing efficacy and safety compared to traditional landmark-based techniques.
Objective: To evaluate the impact of ultrasound-guided regional anesthesia on procedural efficacy and safety outcomes.
Methods: A prospective comparative study was conducted involving 120 patients undergoing elective surgical procedures requiring regional anesthesia. Patients were divided into two groups: Group A (ultrasound-guided technique) and Group B (landmark-based technique). Primary outcomes included block success rate, onset time, and duration of analgesia. Secondary outcomes included complication rates such as vascular puncture, nerve injury, and local anesthetic toxicity.
Results: The ultrasound-guided group demonstrated a significantly higher block success rate (96% vs 82%, p=0.01), shorter onset time (8.2 ± 2.1 vs 12.5 ± 3.4 minutes, p<0.001), and longer duration of analgesia (10.4 ± 2.3 vs 7.6 ± 2.0 hours, p<0.001). Complication rates were significantly lower in the ultrasound group, with reduced incidence of vascular puncture (2% vs 10%) and no cases of nerve injury.
Conclusion: Ultrasound-guided regional anesthesia significantly improves efficacy and reduces complications compared to conventional techniques, making it a preferred approach in modern anesthetic practice.
