Impact of Anesthesia Alarm Volume on Mental Workload in Surgical Trainees

Noise in hospital environments, particularly in operating rooms, poses challenges to both patient comfort and healthcare professionals' performance. Among the sources of noise, anesthesia monitoring alarms are essential for patient safety, yet no clear guidelines exist regarding their optimal sound level. Excessive alarm volume may increase distraction and cognitive load, especially for surgical trainees, potentially impairing their focus and performance during procedures. This randomized pilot interventional study aims to evaluate the impact of anesthesia alarm sound intensity on the mental workload of surgical trainees performing simulated surgeries. Participants will be randomly assigned to conditions with either an optimized alarm volume or a higher standard volume during simulated tasks. Cognitive load will be assessed using objective physiological measures such as heart rate variability and pupillometry, as well as subjective evaluations with tools like the NASA-TLX and SURG-TLX scales. The primary goal is to determine whether an optimized alarm sound level can reduce cognitive strain without compromising vigilance required for patient safety. Findings from this study are expected to provide evidence-based recommendations for auditory ergonomics in operating rooms, ultimately improving working conditions for surgical teams and enhancing both training and patient safety.

The Risk of Surgical Cancellation in Adult Patients Assessed by Telephone Versus In-person for Scheduled Non-cardiac Elective Surgery.

Telemedicine has been regulated in Colombia since 2006, with applications in anesthesia being explored since 2004 to improve accessibility and reduce costs. Although Decree 538 of 2020 expanded telemedicine's medical applications, challenges such as connectivity issues and the need for training remain. Telemedicine has shown promise in rural areas of Colombia, particularly for managing chronic diseases. However, further evidence is needed regarding the effectiveness of telephone pre-anesthetic evaluations. This study aims to investigate the implementation of telephone assessments for non-cardiac surgery and their impact on surgical cancellations compared to in-person pre-anesthetic evaluations. The primary question we seek to answer is: Does telephone pre-anesthetic assessment in non-cardiac surgical patients carry a higher risk of surgical cancellations compared to in-person evaluations? To address this question, we will evaluate patients' medical records in two hospitals where patients were assessed using both telephone and in-person modalities.
