NCT02198885
The NanoMaxx Ultrasound System (SonoSite) in connection with the RP-Xpress (InTouch Technologies) provides a means of transmitting ultrasound images, video, and audio to a remote location in real-time. It has been envisioned that this system be used to diagnose trauma patients with suspected pleural effusion, hemothorax, pneumothorax, or abdominal blockage during prehospital care; under the guidance of in-hospital physicians, paramedics would perform an Focused Assessment with Sonography for Trauma (FAST) examination while trauma patients are transported to hospital via ambulance. The investigators hypothesize that in-hospital physicians interpreting ultrasound images obtained by paramedics during trauma patients' transportation to hospital will reduce time to diagnosis; thus, preparations by emergency physicians, surgeons, and operating room teams to receive critically injured patients may begin earlier, reducing time to intervention during a critical period in patient care. Data will also be collected regarding quality of images obtained in-ambulance and the interaction between paramedics and physicians using the remote-presence system.

While the analgesic effects of opioids are well known, evidence suggest that there are differences in the adverse dizziness of the different opioid types, which may influence the gait function differently. However, this has not been investigated scientifically under controlled conditions. Normal gait function is characterized by cyclic movements with a high degree of predictability. As such, the amount of kinematic variability can provide important information about a condition or an intervention that may affect the gait function . Three-dimensional gait analysis is a recognized method to assess changes in stride-to-stride variability associated with a medical condition or caused by an intervention. Thus, opioid induced changes in gait variability, and possible differences between opioid types, can be assessed objectively from differences in the variability of movements obtained from a three-dimensional gait analysis. The purpose of this study is to investigate differences in gait variability induced by two different single-dose opioid formulations and an inert placebo in healthy volunteers and knee osteoarthritis patients.
