# Patient Satisfaction and Perioperative Outcomes of Wide-Awake Local Anesthesia No Tourniquet Versus Supraclavicular Peripheral Nerve Block in Elective Hand and Forearm Surgery: A Prospective Comparative Study

## TL;DR

This study compares two anesthesia techniques for hand and forearm surgery, finding that one leads to higher patient satisfaction and lower pain.

## Contribution

The study provides a direct comparison of patient satisfaction and outcomes between WALANT and ultrasound-guided nerve blocks in hand surgery.

## Key findings

- Peripheral nerve block patients reported significantly higher satisfaction than WALANT patients.
- Peripheral nerve block was associated with lower intraoperative and postoperative pain scores.
- Total anesthesia-related time was shorter with peripheral nerve block despite longer block performance time.

## Abstract

Background/Objectives: Wide Awake Local Anesthesia No Tourniquet (WALANT) and ultrasound-guided peripheral nerve blocks (PNBs) are increasingly used alternatives to general anesthesia for hand and forearm surgery. While WALANT is commonly perceived as a time-efficient and resource-sparing technique, comparative data regarding patient satisfaction, perioperative pain, and time-related outcomes remain inconsistent. This study aimed to compare WALANT and ultrasound-guided supraclavicular peripheral nerve block techniques with respect to patient satisfaction, perioperative pain, time-related parameters, and surgeon-related outcomes in elective hand and forearm extremity surgery. Methods: This prospective comparative observational study included 80 adult patients undergoing elective hand or forearm surgery. Patients received either WALANT or ultrasound-guided supraclavicular brachial plexus block according to patient preference. The primary outcome was overall patient satisfaction assessed within 24 h postoperatively. Secondary outcomes included block performance time, waiting time, total anesthesia-related time, intraoperative and postoperative pain scores, additional sedation requirements, postoperative numbness, willingness to choose the same anesthetic technique again, safety outcomes and surgeon satisfaction. Results: Overall patient satisfaction was significantly higher in the peripheral nerve block group compared with the WALANT group (median [IQR]: 90 [85–100] vs. 80 [70–90], p < 0.0001). Intraoperative and postoperative pain scores were also significantly lower in the peripheral nerve block group. Although block performance time was longer with the peripheral nerve block, waiting time and total anesthesia-related time were significantly shorter compared with WALANT. Surgeon satisfaction and the need for additional intraoperative sedation did not differ significantly between groups. Conclusions: In elective hand and forearm surgery, ultrasound-guided supraclavicular peripheral nerve block was associated with higher patient satisfaction, lower pain scores, and shorter total anesthesia-related time compared with WALANT. Surgical satisfaction scores were similar with both anesthetic techniques. Considering the heterogeneity of clinical settings and procedural requirements, as well as cost and resource utilization considerations, anesthetic technique selection should be individualized.
