“…The budget required to construct our task trainers is higher than that of other published low-cost models [7][8][9]. However, some of the most expensive items listed in Table 1, including the plastic torso, plywood, placenta, and newborn dolls, are durable supplies that can be reused numerous times throughout multiple educational sessions.…”

“…While there are commercially manufactured RH task trainers, their high material and maintenance costs limit their availability to educators [6]. There are several homemade, low-cost, low-fidelity task trainers described in the literature that are useful for practicing the steps involved in performing a RH [7][8][9]. We developed two low-cost, high-fidelity RH models in which we attempted to maximize a realistic appearance, replicate the anatomic tissue layers, and incorporate the ability to modulate active hemorrhage during skin, subcutaneous, and uterine incision.…”

Resuscitative hysterotomy (RH) is a rare, time-sensitive, invasive procedure that can be frightening for emergency physicians and yet potentially life-saving for fetus and mother. Several low-cost RH task trainers have been described in the literature. We set out to construct a model using improved synthetic materials for the uterine and abdominal wall and to devise hemorrhage capability. The primary aim of this study was to evaluate the model's perceived usefulness of its features. Secondarily, we wished to assess the confidence of emergency medicine (EM) residents before and after performing a RH using our task trainer in a simulated environment.We constructed an inexpensive task trainer that can function both as a table-top model (TTM) and be adapted to a high-fidelity simulator. We created the abdominal wall and uterus from polyurethane carpet padding, subcutaneous fat from upholstery foam, fascia from synthetic chamois, and blood vessels from IV tubing and angio-catheters. We utilized the task trainer during our monthly EM residency simulation conference. After completing a simulation of a gravid female in cardiac arrest requiring a RH on a highfidelity simulator adaptated model (HFSAM), residents repeated the procedure during debriefing on a TTM. Residents then completed anonymous paper surveys in which they rated aspects of the RH model and their procedural confidence on a 10-point Likert scale. 20 EM residents took part in the RH simulation scenario followed by a TTM demonstration. All (100%) residents completed the survey. 11 (55%) of the residents performed a RH on either the HFSAM or the TTM while the others assisted. The residents rated the overall educational value of the training event as very high (mean 9.8 (SD 0.68)). Both the TTM (mean 8.9 (SD 1.15)) and HFSAM (mean 8.7 (SD 1.29)) were similarly rated as highly realistic. Before the simulation session, residents rated their confidence in performing a RH as low (mean 4.0 (SD 2.62)). After the session, they were much more confident in their ability to perform a RH (mean 7.9 (SD 1.48); P<0.001). Most residents rated bleeding as very important to the utility of a RH model (mean 8.6 (SD 1.74)).We demonstrate an inexpensive but realistic RH task trainer that can be used as a stand-alone model or adapted to a high-fidelity simulator. A single simulation using the TTM and the HFSAM lead to increased resident confidence in their ability to perform a RH.

“…Given how infrequently they are done, many residents feel uncomfortable performing them. Simulation has become a method for training residents on how to perform HALO procedures using innovative, high fidelity, and low-cost task trainers (specialized models designed to teach specific skill), however, there is a dearth of high-fidelity task trainers to instruct EM residents on how to perform one of the most HALO trauma procedures -emergent thoracotomy [1].…”

Emergent thoracotomy is a rare but high-stakes procedure for trauma patients. Emergency medicine residents are expected to perform this procedure after graduation, but few get the opportunity to perform it, leading to suboptimal performance and patient morbidity and mortality. Previous low-cost thoracotomy trainers revolve around modifying an existing costly thoracotomy task trainer or bear limited resemblance to actual landmarks and anatomy. This study attempts to bridge this gap by creating a low-cost model with supplies found at most home improvement/craft stores that is more anatomically accurate. We constructed a low fidelity model, which residents ultimately found to be helpful in mastering this rare procedure, and after the training session, they reported a greater level of comfort and familiarization with the procedure.

Purpose of review Caesarean sections are the most commonly performed procedure globally. Simulation-based training for caesarean sections can provide healthcare practitioners a safe and controlled environment to develop this life-saving skill. We systematically reviewed the use of simulation-based training for caesarean section and its effectiveness. Embase, Pubmed, Scopus and Web of Science were searched from inception to June 2019, without language restriction, for studies that included methods of simulation for caesarean section. Studies were selected and data extracted in duplicate. Synthesis analysed common themes on simulation-based training strategies. Recent findings There were 19 relevant studies including the following simulation-based methods: simulators (high and low fidelity), scenario-based drills training, e-learning and combinations. A common theme was simulation for rare events such as perimortem caesarean, impacted foetal head and uterine rupture. Combination studies appeared to provide a more comprehensive training experience. Studies rarely adequately assessed the educational or clinical effectiveness of the simulation methods. Summary There are different types of simulator models and manikins available for caesarean section training. Simulation-based training may improve technical skills and nontechnical skills, in a risk-free environment. More research is needed into simulation training effectiveness and its efficient incorporation into practice for improving outcomes.
