The anatomical theatre played a pivotal role in the evolution of medical education, allowing students to directly observe and participate in the process of dissection. Due to the increase of training programs in clinical anatomy, the Institute of Human Anatomy at the University of Padova has renovated its dissecting room. The main guidelines in planning a new anatomical theatre included: (1), the placement of the teacher and students on the same level in a horizontal anatomical theatre where it is possible to see (theatre) and to perform (dissecting room); (2), in the past, dissection activities were concentrated at the center of the theatre, while in the new anatomical theatre, such activities have been moved to the periphery through projection on surrounding screens—thus, students occupy the center of the theatre between the demonstration table, where the dissection can be seen in real time, and the wall screens, where particular aspects are magnified; (3), three groups of tables are placed with one in front with two lateral flanking tables in regards to the demonstration table, in a semicircular arrangement, and not attached to the floor, which makes the room multifunctional for surgical education, medical students and physician's continued professional development courses; (4), a learning station to introduce the students to the subject of the laboratory; (5), cooperation between anatomists and architects in order to combine the practical needs of a dissection laboratory with new technologies; (6), involvement of the students, representing the clients' needs; and (7), creation of a dissecting room of wide measurements with large windows, since a well‐illuminated space could reduce the potentially negative psychological impact of the dissection laboratory on student morale.

The implementation of clay modeling and rat dissection into the human anatomy and physiology curriculum of a large urban community college          下载免费PDF全文

Carol Haspel  Howard K. Motoike  Erez Lenchner 《Anatomical sciences education》2014,7(1):38-46

After a considerable amount of research and experimentation, cat dissection was replaced with rat dissection and clay modeling in the human anatomy and physiology laboratory curricula at La Guardia Community College (LAGCC), a large urban community college of the City University of New York (CUNY). This article describes the challenges faculty overcame and the techniques used to solve them. Methods involved were: developing a laboratory manual in conjunction with the publisher, holding training sessions for faculty and staff, the development of instructional outlines for students and lesson plans for faculty, the installation of storage facilities to hold mannequins instead of cat specimens, and designing mannequin clean‐up techniques that could be used by more than one thousand students each semester. The effectiveness of these curricular changes was assessed by examining student muscle practical examination grades and the responses of faculty and students to questionnaires. The results demonstrated that the majority of faculty felt prepared to teach using clay modeling and believed the activity was effective in presenting lesson content. Students undertaking clay modeling had significantly higher muscle practical examination grades than students undertaking cat dissection, and the majority of students believed that clay modeling was an effective technique to learn human skeletal, respiratory, and cardiovascular anatomy, which included the names and locations of blood vessels. Furthermore, the majority of students felt that rat dissection helped them learn nervous, digestive, urinary, and reproductive system anatomy. Faculty experience at LAGCC may serve as a resource to other academic institutions developing new curricula for large, on‐going courses.

Body parts removed during surgery: a useful training source     

Macchi V  Porzionato A  Stecco C  Tiengo C  Parenti A  Cestrone A  De Caro R 《Anatomical sciences education》2011,4(3):151-156

Current undergraduate medical curricula provides relatively little time for cadaver dissection. The Department of Human Anatomy and Physiology at the University of Padova has organized a pilot project with the University Hospital for the donation of body parts that are surgically removed for therapeutic purposes and destined under Italian law for destruction. The aim of the project is to improve residents' practical training skills. A survey over the last two years has shown that about 60 body parts were available each year. These included 13 upper limbs or their parts (i.e., forearm with hand, hand, and fingers) and 47 lower limbs or their parts (i.e., legs with feet, feet, or toes). The residents explained the aim of the project to potential donors, and, if patients were willing to donate, their informed consent was obtained. The residents were present in the operating theater during the surgical procedure. In the post-operative phase, the same residents performed dissections on the body part(s), following a teaching schedule prepared by a clinical anatomist, who also assisted residents during their studies. Residents also acted as tutors for undergraduate medical students who attended these dissections. The underlying pathology for which the body part was removed was examined, and surgical procedures were practiced on the body part itself. Our project provided an opportunity for a close relationship between anatomists and surgeons, reinforcing core knowledge of anatomy by appreciation of its clinical importance. The active involvement of residents as learners and as teachers in the various steps of this project improved their knowledge of surgical techniques and helped to establish a sense of ethical responsibility and respect for the human body. This approach involves study of anatomical structures from new perspectives and leads to improved surgical practice.  相似文献   

Student attitudes toward cadaveric dissection at a UK medical school     

Quince TA  Barclay SI  Spear M  Parker RA  Wood DF 《Anatomical sciences education》2011,4(4):200-207

A more humanistic approach toward dissection has emerged. However, student attitudes toward this approach are unknown and the influences on such attitudes are little understood. One hundred and fifty-six first-year medical students participated in a study examining firstly, attitudes toward the process of dissection and the personhood of the cadaver and secondly, the extent to which gender, anxiety, exposure to dissection, bereavement and prior experience of a dead body influenced these attitudes. Attitudes toward dissection were assessed by of levels of agreement toward eleven statements and by selection of adjectives describing possible feelings toward dissection. Students were asked about recent bereavement, whether they had seen a dead body prior to starting their course and exposure to dissection when completing the questionnaire. Validated instruments were used to measure disposition toward generalized anxiety (Hospital Anxiety and Depression Scale) and toward death anxiety (Collett-Lester Death Anxiety Scale). Between 60% and 94% of students held positive attitudes toward the process of dissection and over 70% of students selected 2 or fewer negative adjectives. Students' attitudes toward the personhood of the cadaver were more disparate. Disposition toward anxiety (particularly death anxiety), and exposure to dissection, influenced attitudes. Female gender and recent bereavement exerted a negative influence. Students with higher levels of anxiety experienced more negative feelings and those recently bereaved were less enthusiastic about dissection. Anticipation of dissection may be worse than reality. Sensitive preparation of students prior to entering the dissecting room for the first time may be beneficial.  相似文献   

A randomized trial comparing cadaveric dissection and examination of prosections as applied surgical anatomy teaching pedagogies     

Zong Jie Koh  Marcus Yeow  Dinesh Kumar Srinivasan  Yee Kong Ng  Gominda G. Ponnamperuma  Choon Seng Chong 《Anatomical sciences education》2023,16(1):57-70

Anatomy is an important component in the vertical integration of basic science and clinical practice. Two common pedagogies are cadaveric dissection and examination of prosected specimens. Comparative studies mostly evaluate their immediate effectiveness. A randomized controlled trial design was employed to compare both the immediate and long-term effectiveness of dissection and prosection. Eighty third-year medical students undergoing their surgical rotation from the Yong Loo Lin School of Medicine were randomized into two groups: dissection and prosection. Each participated in a one-day hands-on course following a similar outline that demonstrated surgical anatomy in the context of its clinical relevance. A pre-course test was conducted to establish baseline knowledge. A post-course test was conducted immediately after and at a one-year interval to evaluate learner outcome and knowledge retention. A post-course survey was conducted to assess participant perception. Thirty-nine and thirty-eight participants for the dissection and prosection groups, respectively, were included for analysis. There was no significant difference between mean pre-course test scores between the dissection and prosection groups [12.6 (3.47) vs. 12.7 (3.16), P > 0.05]. Both the mean immediate [27.9 (4.30) vs. 24.9 (4.25), P < 0.05] and 1 year [23.9 (4.15) vs. 19.9 (4.05), P < 0.05] post-course test scores were significantly higher in the dissection group. However, when adjusted for course duration [dissection group took longer than prosection group (mean 411 vs. 265 min)], these findings were negated. There is no conclusive evidence of either pedagogy being superior in teaching surgical anatomy. Based on learner surveys, dissection provides a greater learner experience.  相似文献   

Enhancing Anatomical Instruction: Impact of a Virtual Canine Anatomy Program on Student Outcomes

Innovative reforms in medical education will require instructional tools to support these changes and to give students more flexibility in where and how they learn. At Colorado State University, the software program Virtual Canine Anatomy (VCA) was developed to assist student learning both inside and outside the anatomical laboratory. The program includes interactive anatomical photographs of dissected canine cadavers, dissection instructions with accompanying videos and diagrams, radiographs, and three-dimensional models. There is a need to evaluate the effectiveness of instructional tools like VCA so that decisions on pedagogical delivery can be evidence-based. To measure the impact of VCA on student outcomes in a dissection laboratory, this study compared student attitudes, quiz scores, dissection quality and accuracy, and instructor reliance between students with and without access to VCA. Students with VCA needed less time with teaching assistants (P < 0.01), asked teaching assistants fewer questions (P = 0.04), felt that the dissection was easier (P = 0.02), and were in stronger agreement that they had access to adequate resources (P = 0.02). No differences were found in the dissection quality or accuracy, quiz scores, or attitudes regarding overall enjoyment of the activity between the two groups. This study shows that VCA increases student independence and can be used to enhance anatomical instruction.  相似文献   

Dynamic three-dimensional virtual environment to improve learning of anatomical structures

Increasing number of medical students and limited availability of cadavers have led to a reduction in anatomy teaching through human cadaveric dissection. These changes triggered the emergence of innovative teaching and learning strategies in order to maximize students learning of anatomy. An alternative approach to traditional dissection was presented in an effort to improve content delivery and student satisfaction. The objective of this study is to acquire three-dimensional (3D) anatomical data using structured-light surface scanning to create a dynamic four-dimensional (4D) dissection tool of four regions: neck, male inguinal and femoral areas, female perineum, and brachial plexus. At each dissection step, identified anatomical structures were scanned using a 3D surface scanner (Artec Spider™). Resulting 3D color meshes were overlaid to create a 4D (3D+time) environment. An educational interface was created for neck dissection. Its implementation in the visualization platform allowed 4D virtual dissection by navigating from surface to deep layers and vice versa. A group of 28 second-year medical students and 17 first-year surgery residents completed a satisfaction survey. A majority of medical students (96.4%) and 100% of surgery residents said that they would recommend this tool to their colleagues. According to surgery residents, the main elements of this virtual tool were the realistic high-quality of 3D acquisitions and possibility to focus on each anatomical structure. As for medical students, major elements were the interactivity and entertainment aspect, precision, and accuracy of anatomical structures. This approach proves that innovative solutions to anatomy education can be found to help to maintain critical content and student satisfaction in anatomy curriculum.  相似文献   

Sharps Injuries during Dissection: A Five-Year Retrospective Study in the Context of Safety     

Jakub Foytl  Fraser Chisholm  Ourania Varsou 《Anatomical sciences education》2020,13(2):158-167

The supplementation of lecture-based anatomy teaching with laboratory sessions, involving dissection or anatomical specimens, is commonly used. Hands-on dissection allows students to handle instruments correctly while actively exploring three-dimensional anatomy. However, dissection carries a potential risk of sharps and splash injuries. The aim of this study was to quantify the frequency rate of such cases per 1,000 student-hours of dissection and identify potential factors than might influence safety in anatomy laboratories. Data were retrospectively collected from September 2013 to June 2018 at the University of St Andrews, Scotland, UK. Overall, 35 sharps injuries were recorded in undergraduate medical students, with a frequency rate of 0.384 and no splash cases. A statistically significant, moderate negative association between year of study and frequency rate (rho₍₂₅₎ = −0.663; P < 0.001) was noted. A statistically significant difference in the frequency rate between different semester modules (χ²₍₄₎ = 13.577, P = 0.009) was observed with the difference being between Year 1 Semester 2 and Year 3 Semester 1 (P = 0.004). The decreasing trend with advancing year of study might be linked to increasing dissecting experience or the surface area of the region dissected. The following factors might have contributed to increased safety influencing frequency rates: single-handed blade removal systems; mandatory personal protective equipment; and having only one student dissecting at a given time. The authors propose that safety familiarization alongside standardized training and safety measures, as part of an evidence-based culture shift, will instill safety conscious behaviors and reduce injuries in anatomy laboratories.  相似文献   

Design for assessment of dissection in anatomy laboratory based on group identification of structures and peer evaluation     

Shireen A. Hafez 《Anatomical sciences education》2022,15(6):1045-1059

Dissection is a unique multisensory educational experience and is essential to learning the anatomical construction of the human and animal bodies. This study aims to introduce a specialized design for the assessment of dissection and to discuss the assessment's attributes. The design was a product of the “assessment drives learning” concept and was developed to motivate students to dissect. Students were awarded “dissection points” based on prior group dissection and identification of structures. Students' perception of the design was examined, and content analysis was performed. The assessment consisted of two parts: the first assigning each student group structures to “pin” on their previously dissected cadavers; the second was a group peer evaluation. The most critical factor for the assessment's success was careful selection of structures assigned to students to pin. The assessment was fit for the purpose, valid, reliable, and had a significant educational impact. Eighty-three percent of students (n = 116) recommended maintaining the assessment design, as they felt it promoted a deep approach to learning as well as teamwork while reducing stress to a minimum. A strong correlation (Spearman's rho = 0.46, P < 0.0001) was present between the high rating of the design and the number of structures learned, as well as, high rating and lower stress level (Spearman's rho = 0.40, P < 0.0001). There was no apparent influence of grades on student perception of the effectiveness of the assessment. This specific design of evaluation could be used as part of anatomy education in veterinary and medical schools.  相似文献   

Current and potential use of fresh frozen cadaver in surgical training and anatomical education     

Yong Keun Song  Dong Hyun Jo 《Anatomical sciences education》2022,15(5):957-969

As surgical procedures continue to be more complex, the need for more effective training in anatomy has increased. The study of anatomy plays a significant role in the understanding of the human body as well as in basic and advanced clinical training. Among the different cadaver models, fresh frozen cadavers (FFCs) are known for their realistic tissue quality. The purpose of this article was to review and summarize the preparation procedures for and reported cases involving FFCs. PubMed, Scopus, Medline, and Web of Science were searched for relevant studies. The preparation procedures were divided into five steps: washing, irrigation, freezing, defrosting, and arterial infusion. Not all steps were reported to be mandatory, but omitting one or more could result in a loss of quality. FFCs were reported to be used for various purposes: undergraduate education, general surgery training, vascular surgery training, minimal access surgery (laparoscopic surgery) training, and microsurgery training. In all categories, expert opinions and statistical analyses indicated successful outcomes. The reasons for high satisfaction with FFCs included realistic texture, capability of reenacting actual operations, and accuracy of anatomical locations. The results also revealed the importance and advantages of the dissection courses in surgical training. Since the direct comparison between cadaver models is insufficient, future studies regarding this topic are deemed necessary. In addition, it would be advantageous to develop methods to improve FFC quality, or ideas to optimize this model for certain purposes.  相似文献
