“…Critical to success for trainees in microsurgery is advancing through this steep learning curve. A simulation based training approach has been recognized as the most effective and appropriate learning environment in order to attain the learning curve and test technical proficiency in microsurgery (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11).…”

Determining the Effect of External Stressors and Cognitive Distraction on Microsurgical Skills and Performance

Introduction: Microsurgery is an essential element of Plastic Surgery practice. There is a paucity of studies assessing the impact of stress and cognitive distraction on technical microsurgical performance. The ability to complete cognitive and technical skills in parallel has not been assessed in a microsurgical setting. Aim: To test the hypothesis that cognitive distraction and external stressors negatively affect microsurgical performance in a high fidelity simulation setting. Materials/Methods: Fourteen surgeons across all levels of training undertook 2 microsurgical skills sessions, 1 month apart. Session one established baseline microsurgical skill. In session two, skills were assessed with the introduction of realistic operative room cognitive distractions (ORDIs). Outcome measures were efficiency and accuracy, measured by Time to Completion (TTC) and Anastomosis Lapse Index (ALI), respectively. Key Results: Fourteen participants (6 novices, 5 plastic surgery specialist trainees and 3 consultants) completed both microsurgical skills sessions. In total, 28-microvascular anastomosis were analyzed. Mean baseline TTC for the group was 20.36 min. With cognitive distraction and external stress mean TTC decreased to 17.87 min. Mean baseline ALI score for the group was 3.32 errors per anastomosis. The introduction of cognitive distraction and external stress increased the mean to 4.86 errors per anastomosis. Total errors per anastomosis increased from 91 errors at baseline to 137 errors with cognitive distraction and external stress. Under stress, participants were more efficient but had reduced anastomotic accuracy. Conclusion: Under stress, surgeons were more efficient, this translated into faster completion of a microsurgical anastomosis. Efficiency, however, came at the expense of accuracy.

“…Such practice carried obvious patient safety risks but trainees benefited from learning in an authentic, real setting which provided them with experience of the complex and unpredictable environment of the operating theatre. Technological developments have enhanced the fidelity of virtual reality 14 and greater consideration is now given to using simulations to develop technical skills 15 and to simulate clinical contexts and team interactions. Context is important and growing attention is being shown to ‘in situ’ simulations which take place within the clinical environment.…”

Technology in postgraduate medical education: a dynamic influence on learning?

The influence of technology in medical workplace learning is explored by focusing on three uses: m-learning (notably apps), simulation and social media. Smartphones with point-of-care tools (such as textbooks, drug guides and medical calculators) can support workplace learning and doctors’ decision-making. Simulations can help develop technical skills and team interactions, and ‘in situ’ simulations improve the match between the virtual and the real. Social media (wikis, blogs, networking, YouTube) heralds a more participatory and collaborative approach to knowledge development. These uses of technology are related to Kolb's learning cycle and Eraut's intentions of informal learning. Contentions and controversies with these technologies exist. There is a problem with the terminology commonly adopted to describe the use of technology to enhance learning. Using learning technology in the workplace changes the interaction with others and raises issues of professionalism and etiquette. Lack of regulation makes assessment of app quality a challenge. Distraction and dependency are charges levelled at smartphone use in the workplace and these need further research. Unless addressed, these and other challenges will impede the benefits that technology may bring to postgraduate medical education.

“…Another trend is the increasing number of surgeries performed using minimally invasive surgery (MIS) techniques, and the accepted opinion is that surgeons should attempt to perform the least invasive surgery possible [HVFFTPS12]. On one hand, MIS can significantly reduce the overall operational cost of performing surgeries [TSM*15], but are more complex than traditional open surgery, demanding many years of training in new skills [EL13]. Virtual simulators are therefore necessary tools to scale the access to MIS training to the large demand for experienced professionals.…”

The visual fidelity of realistic renderings in Computer Graphics depends fundamentally upon how we model the appearance of objects resulting from the interaction between light and matter reaching the eye. In this paper, we survey the research addressing appearance modelling of living human tissue. Among the many classes of natural materials already researched in Computer Graphics, living human tissues such as blood and skin have recently seen an increase in attention from graphics research. There is already an incipient but substantial body of literature on this topic, but we also lack a structured review as presented here. We introduce a classification for the approaches using the four types of human tissues as classifiers. We show a growing trend of solutions that use first principles from Physics and Biology as fundamental knowledge upon which the models are built. The organic quality of visual results provided by these Biophysical approaches is mainly determined by the optical properties of biophysical components interacting with light. Beyond just picture making, these models can be used in predictive simulations, with the potential for impact in many other areas.
