Although a wide range of medical applications for three-dimensional printing technology have been recognised, little has been described about its utility in critical care medicine. The aim of this review was to identify three-dimensional printing applications related to critical care practice. A scoping review of the literature was conducted via a systematic search of three databases. A priori specified themes included airway management, procedural support, and simulation and medical education. The search identified 1544 articles, of which 65 were included. Ranging across many applications, most were published since 2016 in non – critical care discipline-specific journals. Most studies related to the application of three-dimensional printed models of simulation and reported good fidelity; however, several studies reported that the models poorly represented human tissue characteristics. Randomised controlled trials found some models were equivalent to commercial airway-related skills trainers. Several studies relating to the use of three-dimensional printing model simulations for spinal and neuraxial procedures reported a high degree of realism, including ultrasonography applications three-dimensional printing technologies. This scoping review identified several novel applications for three-dimensional printing in critical care medicine. Three-dimensional printing technologies have been under-utilised in critical care and provide opportunities for future research.

Applications of 3D printing in critical care medicine: A scoping review

Whitmore

et al. 2021

Anaesth Intensive Care

“…All residents recommended this trainer for future use with medical students and residents, which we believe is likely due to the low incidence of the procedure, leading to an inability to maintain procedural competency. Task trainers are used for many other low incident procedures (i.e., cricothyrotomy [10][11][12] and lateral canthotomy [13,14]) within emergency medicine, so it is not surprising that this trainer was viewed favorably under similar circumstances. Like other important emergency procedures, competency for emergency medicine residents should be considered of utmost importance, especially for those who will practice in areas without prompt urological consultation.…”

A Low-Cost Priapism Detumescence Simulator for Emergency Medicine Residents

Introduction: Ischemic priapism is an emergent condition requiring immediate intervention. However, the incidence is estimated to be very low. Given the low incidence of this pathology, some emergency medicine residents do not have the opportunity to perform needle aspiration, the critical procedure to achieve detumescence. We sought to fill this void by creating low-cost, high-fidelity trainers for emergency medicine resident procedural competency.Methods: Using items obtained online and through our hospital's simulation department, we created a lowcost priapism trainer from previously described literature. Residents completed a lecture, lab, and short post-course survey regarding helpfulness, realism, prior procedure experience, and future applicability of our training device. Descriptive data were calculated using the median with interquartile range.Results: The trainer cost roughly $25 to create per unit. All participants rated the trainer a 5 for helpfulness. When asked if the lab appeared realistic, there were overly positive responses with a median of 5 (interquartile range [IQR] 4-5), with every respondent selecting either realistic (4 on the Likert scale) or very realistic (5 on the Likert scale). All participants (100%) agreed that they would recommend the use of this trainer for future medical students and residents.Conclusion: Priapism, specifically ischemic priapism, is truly an emergent condition requiring immediate intervention. The incidence of this condition is low, and some emergency medicine residents may not have the opportunity to perform the procedure during training. Given the need for simulated experiences, we developed a low-cost, high-fidelity trainer that was found to be helpful and realistic to emergency medicine residents. While other models exist, our model minimizes cost while maximizing realism.

“…Recent publications reflect growing enthusiasm and scope for innovation, particularly in the realm of airway management in anaesthesia. 1–8 Despite this, there is a paucity of work in 3D printed neonatal, infant and paediatric airways within anaesthesia. Paediatric airway crises are rare but high-stakes scenarios, highlighting the importance of simulation training.…”

A three-dimensional (3D) printed paediatric trachea for airway management training

Anaesth Intensive Care

There is a deficit of commercially available paediatric airway models for anaesthesia airway management training, particularly for infant front-of-neck access and customised airway planning. Acknowledging this, we created a three-dimensional printed prototype for an affordable, high-fidelity training device, incorporating realistic tactile feedback, reproducibility and potential for modification for specific patient pathologies. Our model, created on a Stratasys Polyjet J750™ (Rehovot, Israel) printer, is a novel and useful educational tool in paediatric airway management, and we are pleased to share access to this resource with readers. Our work adds credence to three-dimensional printing as an accessible, reproducible and pluripotent technology in clinical anaesthesia.
