Checklists can be used to improve and standardize safety critical processes and their communication. The introduction of potentially harmful medical technology and equipment has created additional requirements for the safe delivery of health care. ⋯ The checklist provided different functionality for the different users, ranging from a memory/attention support to a standardized form of communication on safety matters. However, the rigidity afforded by the electronic implementation, showed some serious drawbacks over the prior, simpler, paper-based versions.

Comparative StudyPerformance comparison of laryngoscopy and suction techniques in a hemorrhagic airway manikin simulator: direct laryngoscopy with Yankauer vs. Storz CMAC with attached suction tip.
Airway management of the hemorrhagic airway can be a difficult skill to master as trainee exposure to this difficult airway may be limited. In this study, we employed a hemorrhagic airway simulator along with a videolaryngoscope and the Storz Boedker-Doerges (BD) suction blade. These devices provided improved intubation performance in this model with respect to traditional direct laryngoscope (DL) and VL blades. This study shows that use of a hemorrhagic simulator could be an effective and valuable training tool in difficult airway intubation training.

BodyWindows: enhancing a mannequin with projective augmented reality for exploring anatomy, physiology and medical procedures.
Augmented reality offers the potential to radically extend and enhance the capabilities of physical medical simulators such as full-body mannequin trainers. We have developed a system that transforms the surface of a mannequin simulator into both a display screen and an input device. The BodyWindows system enables a user to open, size, and reposition multiple viewports onto the simulator body. ⋯ Viewport windows can be overlapping and show anatomy at different depths, creating the illusion of "cutting" multiple windows into the body to reveal structures at different depths from the surface. The developed low-cost interface employees an IR light pen and the Nintendo Wiimote. We also report experiments using the Microsoft Kinect computer vision sensor to provide a completely hand-gesture based interface.

An aneurysm clipping training module for the neurosurgical training simulator NeuroSim.
Having introduced NeuroSim, the prototype of a neurosurgical training simulator at MMVR18, we present our first medical training module. NeuroSim is based on virtual reality and uses real-time algorithms for simulating tissue. ⋯ Having implemented some abstract tasks to train basic skills like hand-eye coordination or the handling of the microscope last year, we now present a medical module where an aneurysm has to be clipped. NeuroSim has been developed in cooperation with the neurosurgical clinic of the University of Heidelberg and VRmagic GmbH in Mannheim.

User preference comparing a conventional videolaryngoscope blade vs. a novel suction videolaryngoscope blade in simulated hemorrhagic airway intubation.
The hemorrhagic airway makes visualization during laryngoscopy and intubation difficult. A specially designed videolaryngoscope blade with integrated suction was developed and studied in a simulated hemorrhagic airway at the Omaha VA Medical Center. Results show that, if available, many users would choose to include this new suction device in their standard airway carts due to its "always there" design.
