Microsurgery Workout: A Novel Simulation Training Curriculum Based on Nonliving Models
Validation study published in Plast Reconstr Surg (2016)
Abstract
BACKGROUND: Currently, there are no valid training programs based solely on nonliving models. The authors aimed to develop and validate a microsurgery training program based on nonliving models and assess the transfer of skills to a live rat model. METHODS: Postgraduate year-3 general surgery residents were assessed in a 17-session program, performing arterial and venous end-to-end anastomosis on ex vivo chicken models. Procedures were recorded and rated by two blinded experts using validated global and specific scales (objective structured assessment of technical skills) and a validated checklist. Operating times and patency rates were assessed. Hand-motion analysis was used to measure economy of movements. After training, residents performed an arterial and venous end-to-end anastomosis on live rats. Results were compared to six experienced surgeons in the same models. Values of p < 0.05 were considered statistically significant. RESULTS: Learning curves were achieved. Ten residents improved their median global and specific objective structured assessment of technical skills scores for artery [10 (range, 8 to 10) versus 28 (range, 27 to 29), p < 0.05; and 8 (range, 7 to 9) versus 28 (range, 27 to 28), p < 0.05] and vein [8 (range, 8 to 11) versus 28 (range, 27 to 28), p < 0.05; and 8 (range, 7 to 9) versus 28 (range, 27 to 29), p < 0.05]. Checklist scores also improved for both procedures (p < 0.05). Trainees were slower and less efficient than experienced surgeons (p < 0.05). In the living rat, patency rates at 30 minutes were 100 percent and 50 percent for artery and vein, respectively. CONCLUSIONS: Significant acquisition of microsurgical skills was achieved by trainees to a level similar to that of experienced surgeons. Acquired skills were transferred to a more complex live model.

Резюме
17-session microsurgery training on chicken models significantly improved SAMS scores in 10 residents to expert levels, with successful transfer to live rat model.
Почему это важно для гирудотерапии
В аннотации описывается программа обучения микрохирургии для ординаторов третьего года обучения по общей хирургии с использованием моделей ex vivo на цыплёнке, оцениваются артериальный и венозный анастомозы конец-в-конец с помощью валидированных шкал, контрольных списков, продолжительности операции, показателей проходимости и анализа движений рук с последующим тестированием переноса навыков на живую модель крысы. Десять ординаторов продемонстрировали значительное улучшение по ряду показателей, хотя они оставались медленнее и менее эффективны, чем опытные хирурги; в живой модели крысы показатели проходимости через 30 минут составили 100% для артерии и 50% для вены. В данной статье не содержится сведений о пиявках, терапии пиявками или секретоме пиявок, и она не имеет обоснованной релевантности для сферы деятельности ASH.
