Use of a malleable bougie and curved forceps with videolaryngoscopy in airway management training in a cadaver model - a pilot study.
The wider angle of view of videolaryngoscopy versus standard direct laryngoscopy requires an assessment of the adjunctive devices used to facilitate intubation. In this study, subjects performed malleable bougie-assisted intubation and curved forceps removal of a glottic foreign body using videolaryngoscopy on a lightly embalmed cadaver and completed a post-procedure questionnaire. All subjects valued access to the malleable bougie available at their hospitals and 82% valued access to the curved forceps. Malleable bougie and curved forceps seem well-suited to facilitate videolaryngoscopic airway management.

Rate of surgery in a sample of patients fulfilling the SRS inclusion criteria treated with a Chêneau brace of actual standard.
Studies investigating the outcome of conservative scoliosis treatment differ widely with respect to the inclusion criteria used. Prospective cohort studies are available using the SRS inclusion criteria for studies on bracing. This seems to provide a great advantage to compare different strategies of bracing against each other. As we have gathered all data of the patients treated with a Chêneau light TM between June 2005 and November 2007 it was possible to identify the sample of patients fulfilling the SRS inclusion criteria from the whole sample. ⋯ Rate of surgery can be reduced with the help of Chêneau braces of the latest standard and satisfactory in-brace correction. Brace treatment with the Chêneau brace seems effective and therefore clearly is indicated. Clinical outcomes may be more important for the patient than radiologic outcomes.

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 ICU clinical information system - clinicians' expectations and perceptions of its impact.
The Intensive Care Unit (ICU) is an information intense environment where Clinical Information Systems (CISs) can greatly impact patient care and the workload of clinicians. With the introduction of an ICU CIS imminent across New South Wales hospitals, we aimed to understand how ICU clinicians perceived a new system would impact on work practices in Australian ICUs, as much of the current evidence is generated from overseas. We conducted interviews with 66 doctors and nurses in 3 ICUs without a CIS. ⋯ This information provides valuable evidence in the Australian setting regarding clinicians' expectations of a new ICU CIS to assist with future implementations. It also provides baseline data as a foundation for future research once the CIS is implemented. It is clear that robust quantitative studies are required to gain a detailed understanding of how a new CIS will impact clinicians' work processes and that appropriate training is crucial for full benefits to be achieved.

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.
