As this difference did not seem to be mediated by improved peritoneal fluid drainage, fascial closure rates, or markers of systemic inflammation, it should be confirmed by a multicenter trial.

The remote real-time guidance or observation of an EFAST using TS appears feasible. Most technical problems were quickly overcome. Further evaluation of this approach and technology is warranted in more remote settings with less experienced personnel.

The emergent exclusion of APN-PTX can be immediately accomplished by a remote expert economically linked to almost any responder over cellular networks. Further work should explore the range of other physiologic functions and anatomy that could be so remotely assessed.

We established a pilot tele-ultrasound system between a rural referring hospital and a tertiary care trauma centre to facilitate telementoring during acute trauma resuscitations. Over a 12-month period, 23 tele-ultrasound examinations were completed. The clinical protocol examined both the Focused Assessment with Sonography for Trauma (FAST) and the Extended FAST (EFAST) for pneumothoraxes. Twenty of the examinations were conducted during acute trauma resuscitations and three during live patient simulations. FAST examinations were completed in all 23 cases and EFAST examinations in 17 cases. There were 18 clinical users, of whom 14 completed a survey (76% response rate). Overall, 93% of respondents were either satisfied or very satisfied with the telemedicine interaction and agreed or strongly agreed that the technology could potentially benefit injured patients in the far north of Canada. In addition, 93% of the respondents felt that the project had improved collegiality between the two institutions involved. The majority of respondents (71%) agreed or strongly agreed that the project had improved their ultrasound skills. We believe that as further experience is obtained, tele-ultrasound will prove to be an important aid to the care of remotely injured and ill patients.

Breadboard testing of the prototype components has shown spatial resolution of 30 microm, greatly exceeding our expectations. Neurosurgeons will not only be able to perform current procedures with a higher margin of safety but also must speculate on techniques that have hitherto not even been contemplated. This includes coupling the robot to intelligent tools that interrogate tissue before its manipulation and the potential of molecular imaging to transform neurosurgical research into surgical exploration of the cell, not the organ.

UNEs can confidently be guided to obtain critical findings using simple information technology resources, based on the receiving/transmitting device found in most trauma surgeons' pocket or briefcase. Global US mentoring requires only Internet connectivity and initiative.

BackgroundPoint-of-care ultrasound (POC-US) use is increasingly common as equipment costs decrease and availability increases. Despite the utility of POC-US in trained hands, there are many situations wherein patients could benefit from the added safety of POC-US guidance, yet trained users are unavailable. We therefore hypothesized that currently available and economic ‘off-the-shelf’ technologies could facilitate remote mentoring of a nurse practitioner (NP) to assess for recurrent pneumothoraces (PTXs) after chest tube removal.MethodsThe simple remote telementored ultrasound system consisted of a handheld ultrasound machine, head-mounted video camera, microphone, and software on a laptop computer. The video output of the handheld ultrasound machine and a macroscopic view of the NP's hands were displayed to a remote trauma surgeon mentor. The mentor instructed the NP on probe position and US machine settings and provided real-time guidance and image interpretation via encrypted video conferencing software using an Internet service provider. Thirteen pleural exams after chest tube removal were conducted.ResultsThirteen patients (26 lung fields) were examined. The remote exam was possible in all cases with good connectivity including one trans-Atlantic interpretation. Compared to the subsequent upright chest radiograph, there were 4 true-positive remotely diagnosed PTXs, 2 false-negative diagnoses, and 20 true-negative diagnoses for 66% sensitivity, 100% specificity, and 92% accuracy for remotely guided chest examination.ConclusionsRemotely guiding a NP to perform thoracic ultrasound examinations after tube thoracostomy removal can be simply and effectively performed over encrypted commercial software using low-cost hardware. As informatics constantly improves, mentored remote examinations may further empower clinical care providers in austere settings.
