“…Our results differ from those of several randomised controlled trials on mental imagery in postgraduate education. Studies that involved surgical trainees’ ‘warming up’ with mental imagery16 17 described significantly improved performance with a warm-up before laparoscopic surgery. However, when considering the effects of warm-up on the different aspects of psychomotor performance, Paschold et al 27 found that these were affected by the nature of the warm-up, the type of surgery and the expertise of the surgeon.…”

“…Several studies have investigated mental imagery in postgraduate settings,16–19 but only one small study used it during intravenous cannulation performed by undergraduate students 20. Mental imagery, due to its simplicity, could facilitate learning and skill maintenance in undergraduate medical student curricula, and release educators from the physical and temporal presence of bedside teaching.…”

IntroductionIntravenous cannulation is a core competence in medicine, but is considered challenging to learn. This study investigates the effectiveness of three educational strategies used to refresh the intravenous cannulation skills of first-year medical students: mental imagery, part-task trainer simulation and written instructions.Materials and methodsIn this single-centre randomised controlled trial, first-year medical students were assigned to one of three different refresher tutorials on intravenous cannulation. Six months after their compulsory 4 hour instructor-led intravenous-cannulation course, each student was randomised to a 6 min self-learning tutorial: a mental imagery audioguide session, hands-on intravenous cannulation on a part-task trainer or reading written instructions.Immediately after the refresher tutorials, trained evaluators who were blinded to the randomised group assessed the students’ performance. Each evaluator completed a 15-item standardised checklist in an Objective Structured Clinical Examination (OSCE) station for intravenous cannulation. We performed a descriptive analysis of the data and a one-way analysis of variance. Additionally, we investigated the influence of previous intravenous cannulation experience on the total OSCE score.Results and discussionOn analysing the 309 students’ results, we did not find differences in the total rating of the performance (in percentage) between the three groups at the OSCE station (mental imagery group: 72.0%±17.9%; part-task trainer group: 74.4%±15.6%; written instructions group: 69.9%±16.6%, p=0.158). Multiple linear regression showed a small but statistically significant effect of students’ previous intravenous cannulation experience on OSCE performance. With the same outcome, written instructions and mental imagery had a better return on effort, compared with resource-intensive hands-on training with part-task trainers.ConclusionA single, short refresher seems to have a limited effect on intravenous-cannulation skills in first-year medical students. Less resource-intensive interventions, such as written instructions or mental imagery, are effective compared with hands-on part-task trainer simulation for refreshing this simple but important skill.Trial registration numberAEARCTR-0008043.

“…Greater hand smoothness of movement (p < 0.03) 14 Smoothness of instruments (p < 0.05) 14 demonstrated, with rates of orthopaedic postoperative infections thought to be associated with case order, potentially secondary to inadequate cleaning interoperatively. 41 While most studies have found second and subsequent cases have shorter operative times, in comparison to the primary case of the day, 39,42 Makhdom et al 43 found that second and subsequent cases were significantly slower than the first case of the day. Lavelle et al 42 found that patient on second and subsequent cases on the operating list had shorter operative times, and hospital lengths of stay.…”

“…They concluded that "warming up" may have beneficial outcomes as indicated by the finding that the conventional training group developed outcomes similar to that of the interventional arm with more exposure. Makhdom et al 62 investigated this concept by comparing the first patient's outcome with the outcomes of subsequent patients on the operating list, and noted no significant difference in outcomes between first and subsequent total hip arthroplasties on the theatre list.…”

Background: Simulated surgical learning is an evolving training modality for surgical trainees. Its use in transferring simulation-based skills to the operating room is an integral aspect of its use as a pedagogical tool for surgical trainees in an era of reduced working hours and fewer intra-operative opportunities. These systems may allow trainees to upskill in simulated scenarios leading to improved skillsets and patient safety. The aim of this review was to evaluate if acquisition of surgical skills developed in simulated procedures results in improved intra-operative performance and whether this can be integrated into current surgical curricula. Methods: A systematic search was conducted using PubMed, OVID Medline and CINAHL. Articles included were based on specific inclusion and exclusion criteria. Critical appraisal tools were used to assess each article's authenticity, applicability and quality of results. Results: Twenty-six studies were reviewed in full and included in this review according to PRISMA guidelines. Thematic analysis yielded four main themes: predictive validity, surgical curriculum, timing of training, clinical outcomes. All studies demonstrated validity. Conclusion:A heterogeneous group of studies demonstrated mixed findings in the predictive validity of virtual reality learning. However, adaptation into surgical curricula in conjunction with other forms of surgical education yielded positive results, with predictive validity demonstrated in surgical trainees. Further research is required to elicit optimal training stages and use of simulation in development of non-technical skills.

Does warming up improve surgical outcome in total hip arthroplasty?

Abstract: Warming up prior to performing surgery does not make a difference for primary THA when performed by an experienced surgeon. However, these results may not reflect its effect on procedures that require fine motor skills or done by an orthopedic trainee or less experienced surgeons.
