Student Bio:
Brenda Dierestil 
A Doctor of Nurse Anesthesia student at FSU Panama City. Her current research investigates the impact of weight-based lidocaine dosing in propofol-based sedation for esophagogastroduodenoscopy (EGD) procedures, aiming to optimize sedation outcomes and reduce adverse events such as apnea and hemodynamic instability. With a strong commitment to improving patient safety and clinical practices, Brenda strives to bridge the gap between research and real-world application, contributing to the evolution of anesthesia care in procedural sedation.

Poster Title: Lidocaine Dosage for EGD Sedation
Abstract:
Propofol-based sedation for esophagogastroduodenoscopy (EGD) often requires careful anesthetic management to minimize adverse events. Lidocaine, an adjuvant to propofol, can reduce propofol requirements and improve patient outcomes. This study aimed to evaluate the impact of a weight-based lidocaine dosing regimen (1.5 mg/kg) on apneic events compared to a fixed low dose (50 mg) in adult patients undergoing EGD. A pre- and post-intervention survey design was employed to assess clinical practice changes among anesthesia providers within a U.S. hospital in the eastern region. Post-intervention, adherence to the recommended lidocaine dosing increased significantly, leading to a reduction in propofol requirements and fewer adverse events like apnea and hemodynamic instability. Adherence to the recommended dosage of 1.5 mg/kg of lidocaine 2% increased notably, with the number of practitioners adhering to this guideline doubling from 10 to 20 out of 25 respondents. Additionally, 18 practitioners reported notable improvements, including reduced propofol requirements and a lower incidence of adverse events such as apnea and hemodynamic instability. These findings highlight the importance of targeted education and evidence-based dosing practices in improving patient safety and optimizing anesthesia care for EGD procedures, illustrating how a well-structured educational initiative can bridge the gap between evidence-based recommendations and real-world clinical practice.
