Ropivacaine/Dexmedetomidine Scalp Block (Ro-Dex Technique) for Awake Surgery and Functional Stereotactic Surgery

Abstract

Introduction: In the realm of neurosurgery, optimizing patient comfort and procedural precision is paramount. Awake surgery, particularly in eloquent brain areas, demands meticulous pain management without compromising patient cooperation. The scalp block technique, specifically utilizing ropivacaine/dexmedetomidine, shows promise in this context. This study explores the Ro-Dex technique’s efficacy in awake surgery and stereotactic procedures, aiming to improve outcomes and patient satisfaction.

Material and Methods: This prospective observational study, conducted at CMN “20 de Noviembre,” assesses the Ro- Dex technique’s impact on perioperative outcomes. Patients undergoing awake surgery or stereotactic procedures received the Ro-Dex technique, while a control group received standard care. Data collection included pain scores, surgical duration, and patient satisfaction using the CRES-4 scale. Statistical analyses were performed using R Studio software.

Design: The study enrolled patients aged 12 to 65 undergoing awake surgery or stereotactic procedures from January 2020 to June 2022. Exclusion criteria included psychiatric disorders, cardiac arrhythmias, and renal dysfunction. The Ro-Dex technique was administered preoperatively, and outcomes were compared with a control group.

Discussion: The Ro-Dex technique demonstrated efficacy in reducing pain, surgical duration, and anesthetic requirements. Patient satisfaction was notably higher, indicating improved perioperative experiences. These findings suggest the Ro-Dex technique’s potential to enhance awake surgery and stereotactic procedures.

Conclusion: The Ro-Dex technique holds promise as an adjunct in neurosurgical practice, offering improved pain management and patient satisfaction. Further multicenter studies are warranted to validate its efficacy and establish standardized protocols.
