The Impact of Implementing the Vortex Approach on Airway Management Performance in Stressed Medical Students: A Randomized Controlled Simulation Study.

BACKGROUND The ability to manage airways in emergencies is paramount, especially for less experienced medical students. Although the Vortex Approach, a useful scheme to support decision-making during airway management, promises structured guidance, there's limited research on its benefits among students. Our study aimed to evaluate student proficiency in a simulated difficult airway scenario and assess the advantages of the Vortex Approach. MATERIAL AND METHODS Medical students initially practiced on low-fidelity mannequins. Subsequently, they were divided into Vortex (n=48) and control groups (n=48). The Vortex group received specialized training. Both groups encountered a simulated scenario focusing on proper ventilation and supraglottic device insertion when traditional intubation failed. Performance was assessed using the airway management outcome score (AMOS). RESULTS The Vortex-trained group demonstrated superior capabilities. Fewer participants exceeded 3 lifeline interventions (4.2% vs 16.7%, P=0.046). The Vortex group consistently optimized subsequent attempts (31.3% vs 10.4%, P=0.01) and reduced prolonged apnea episodes (47.9% vs 81.3%, P=0.0009). Their AMOS scores were notably higher (56.3% vs 27.1%, AMOS=2, P=0.002), reflecting better patient outcomes (41.7% vs 10.4%, P=0.0005). CONCLUSIONS There is a marked need to enhance airway management skills among senior medical students. The Vortex Approach, even after brief exposure, yields significant skill improvements, underscoring its potential as a pivotal component in medical training. Integrating it into the curriculum could bridge the evident skill gap, optimizing future patient care.

A Simulation Study Using a Quality Cardiopulmonary Resuscitation Medical Manikin to Evaluate the Effects of Using Personal Protective Equipment on Performance of Emergency Resuscitation by Medical Students from the University of Silesia, Katowice, Poland and Non-Medical Personnel.

BACKGROUND During the Coronavirus disease 2019 (COVID-19) pandemic, personal protective equipment (PPE) is used during medical resuscitation aerosol-generating procedures (AGP). This simulation study aimed to evaluate the effects of PPE on the performance of emergency resuscitation by medical students from the University of Silesia, Katowice, Poland and non-medical personnel, and used a quality cardiopulmonary resuscitation (Q-CPR) medical manikin. MATERIAL AND METHODS A simulation study was conducted using the Resusci Anne quality cardiopulmonary resuscitation (Q-CPR) medical manikin (Laerdal Medical AS, Norway). Participants were divided into 2 groups: a medical group of 50 and a non-medical group of 52, matched in pairs. Each pair performed 10 min of manual CPR with a compression-ventilation ratio of 30: 2 wearing PPE for AGP. The reference method was manual CPR wearing casual clothes along with surgical masks and latex gloves. Data about compression and ventilation were gathered using the QCPR Training application from Laerdal Medical. RESULTS Data analyses indicated statistically significant differences between medical students using PPE for AGP and basic protection: average rate of chest compressions (123 vs 114 per min; P=0.004), chest recoil (69 vs 93; P=0.0050, correct depth of chest compressions (86.5 vs 97; P=0.0081), quality of ventilation (85 vs 89; P=0.0041). Among non-medical personnel however, a statistically significant difference was in the quality of ventilation (69-85.5; P=0.0032). CONCLUSIONS The findings from this study showed that the use of PPE for AGP during CPR was associated with slower average speed of chest compressions, less chest recoil, incorrect depth of chest compressions, and lower quality of ventilation.
