“…Thus, Smith et al ( 2015 ) provide evidence for the feasibility of cadaver-based surgical training in remote locations. Furthermore, it is important to note that the creation of a human body donor laboratory that includes strong downdraft ventilation can be accomplished with little funding and with readily available materials (Zdilla 2020 , 2021a ; b ).…”

Utilization of human material in surgical simulation training has been well-established as an effective teaching method. Despite the value of donor-based surgical simulation training, its application may be hampered by difficulties regarding access to donated bodies. Therefore, the aim of this review is to assess body donation and body acquisition practices with regard to surgical simulation training programs around the world. The results of this review highlight discrepancies regarding body donation practices and surgical simulation programs among continents and countries. The utilization of donor bodies in surgical simulation appears to mirror body donation practices. In countries that rely mostly or exclusively upon unclaimed bodies or executed criminals, there are scant reports of donor-based surgical simulation programs. In countries where willed-body donation is the principal source of human material, there tend to be many surgical simulation programs that incorporate human material as part of surgical training. This review suggests that, in anatomical and surgical education, the utilization of active willed-body donation programs, as opposed to the utilization of unclaimed human bodies, positively corresponds with the development of beneficial donor-based surgical simulation programs. Likewise, donor-based surgical simulation training programs may have an influence on the perpetualization of willed-body donations.

Anatomy in the context of medical or health science often requires dissection. Anatomical dissection is the purposeful and procedural exploration of the human tissues and organs by physically cutting through defined body planes, regions, and organs to access, define and explore the structures in a manner that facilitates learning. Anatomical dissection is a basic requirement for anatomical and medical education. It is a requirement in certain other fields of health sciences as well. Unfortunately, in many instances, the prosector and dissector in the anatomy laboratories are not considered for the hazards to which they are exposed whether in their health plans or remuneration package. Dissectors, unlike conventional hospital laboratory workers are often considered routine workers or teaching assistants. This is the case, for example, in many African medical institutions. Administrators possibly presume that hazards are only associated with service laboratories in the hospital or teaching hospital departments. It would therefore serve the purpose of advocacy, education, and orientation to highlight the hazards that these individuals who serve as dissectors, prosectors and laboratory staff members are exposed to. This commentary highlights the nature and sources of risks that anatomists who dissect, prosect and work in anatomical laboratories are exposed to. It also highlights how the rights and health of anatomists who dissect can be protected with specific recommendations. Hence, the recommendations speak to policies and practices that are required to serve this purpose. After highlighting the major risks that anatomists who dissect might face, and the major causes of the risks, we wish to propose ways by which these could be addressed based on these key considerations: protect, prevent, and compensate. This is what we have also termed the PPC principle for protecting the health and professional rights of anatomists who dissect and work in anatomical laboratories.

“…The levels are listed according to their effectiveness, starting from the least effective, which is wearing personal protective equipment and administrative control (changing the way people work), engineering controls (isolating people from the hazard), substitution (replacing the threat) to the most effective, which is elimination (physically remove the risk) (NIOSH 2015 ). There were publications on high-cost gross anatomy engineering control equipment such as ventilation system modification, local exhaust ventilation, photocatalytic oxidation system, and chemical neutralization, but none of the simple methods, such as improving formaldehyde circulation by dispersing the dissection tables and lessening the formaldehyde vapor trap (Coskey and Gest 2015 , Ohmichi et al 2007 ; Scheepers et al 2018 ; Waschke et al 2019 ; Zdilla 2021 ).…”

Formaldehyde has carcinogenic properties. It is associated with nasopharyngeal cancer and causes irritation of the eyes, nose, throat, and respiratory system. Formaldehyde exposure is a significant health concern for those participating in the gross anatomy laboratory, but no learning method can substitute cadaver dissection. We performed a formaldehyde level study in 2018, which found that most of the breathing zone (S-level) and environment (R-level) formaldehyde levels during laboratory sessions at the Faculty of Medicine Siriraj Hospital exceeded international ceiling standards. In the academic year 2019, we adapted the engineering rationale of the NIOSH hierarchy of controls to facilitate formaldehyde clearance by opening the dissection table covers and increasing the area per dissection table, then measured formaldehyde ceiling levels by formaldehyde detector tube with a gas-piston hand pump during (1) body wall, (2) upper limb, (3) head-neck, (4) thorax, (5) spinal cord removal, (6) lower limb, (7) abdomen, and (8) organs of special senses dissection sessions and comparing the results with the 2018 study. The perineum region data were excluded from analyses due to the laboratory closure in 2019 from the COVID-19 outbreak. There were statistically significant differences between the 2018 and 2019 S-levels ( p < 0.001) and R-levels ( p < 0.001). The mean S-level decreased by 64.18% from 1.34 ± 0.71 to 0.48 ± 0.26 ppm, and the mean R-level decreased by 70.18% from 0.57 ± 0.27 to 0.17 ± 0.09 ppm. The highest formaldehyde level in 2019 was the S-level in the body wall region (1.04 ± 0.3 ppm), followed by the S-level in the abdomen region (0.56 ± 0.08 ppm) and the spinal cord removal region (0.51 ± 0.29 ppm). All 2019 formaldehyde levels passed the OSHA 15-min STEL standard (2 ppm). The R-level in the special sense region (0.06 ± 0.02 ppm) passed the NIOSH 15-min ceiling limit (0.1 ppm). Three levels for 2019 were very close: the R-level in the head-neck region (0.11 ± 0.08 ppm), the abdomen region (0.11 ± 0.08), the body wall region (0.14 ± 0.12 ppm), and the S-level in the special sense region (0.12 ± 0.04 ppm). In summary, extensive analysis and removal of factors impeding formaldehyde clearance can improve the general ventilation system and achieve the OSHA 15-min STEL standard.
