摘要

Purpose

Wide Awake Local Anesthesia No Tourniquet (WALANT) has gained significant attention since its introduction in 2005. Over 343 publications since 2013 highlight its increasing use in nerve decompression surgeries. WALANT is known for its safety benefits, cost-effectivenes and improved patient experience compared to traditional sedation and tourniquet-based methods. This review examines the advantages of WALANT in nerve decompression surgery, emphasizing its growing adoption and benefits.

Methods

A comprehensive review of the WALANT technique is provided, focusing on injection strategies, including buffered lidocaine with epinephrine, proper needle placement and generous volume of tumescent anesthesia. Specific injection protocols and surgical approaches are discussed for various nerve decompression procedures such as carpal tunnel, lacertus, cubital tunnel, radial tunnel and lateral intermuscular septum releases.

Results

WALANT eliminates sedation-related risks such as nausea, aspiration pneumonia and thromboembolism, making it suitable for high-risk patients (ASA 4). It reduces healthcare costs by decreasing the need for post-anesthesia care units and operating in minor procedure rooms. The technique fosters greater surgeon-patient interaction, reduces hospital stays and avoids preoperative fasting and testing. WALANT has demonstrated positive outcomes across multiple nerve decompression procedures.

Conclusion

WALANT provides a transformative approach in nerve decompression surgery, offering enhanced safety, cost-effectiveness and improved patient-centered care. It significantly contributes to positive surgical outcomes, making it a valuable technique for both patients and healthcare providers.
