“…Four studies related to the development of customised devices to facilitate ventilation. 61–64 These included a facial prosthetic to optimise mask fit in a patient with facial abnormalities and a silicone mask for a child with Trisomy 21, both constructed from 3D-printed negative moulds. 61 , 62 One study compared the use of an i-gel® (Intersurgical Ltd, Wokingham, Berkshire, UK) supraglottic airway with a 3D-printed modified version in 48 cadavers and found that there was a significant reduction in the force exerted on the airway mucosa and a significant increase in tidal volume during positive pressure ventilation with the printed device.…”

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.

“…A recent study involving four medical students and two instructors examined and proved the usability of 3D-printed stethoscopes in auscultation training, in which they simulated mitral stenosis, mitral regurgitation, and aortic stenosis [ 24 ]. Supraglottic airway management devices have been successfully developed and tested on Thiel embalmed bodies [ 25 ]; however, no previous work has reported the use of 3D printing for manufacturing MAYO tubes [ 26 ].…”

“…Recently, the microdevices processed by 3D printing technology have grown exponentially, demonstrating the great potential for cell biology, medical laboratory science, gene diagnosis [14,15]. Compared with traditional processing technology, 3D printing technology have incomparable flexibility and accuracy [16]. Several 3D printing materials have biocompatibility, which can meet the research and application needs of biological sciences and medicine [17].…”

Leukocytes have an essential role in patient clinical trajectories and progression. Traditional methods of leukocyte enrichment have many significant limitations for current applications. It is demonstrated a novel 3D printing leukocyte sorting accumulator that combines with centrifugation to ensure label-free initial leukocyte enrichment based on cell density and size. The internal structure of leukocyte sorting accumulator (revealed here in a new design, leukocyte sorting accumulator-3, upgraded from earlier models), optimizes localization of the buffy coat fraction and the length of the period allocated for a second centrifugation step to deliver a higher recovery of buffy coats than earlier models. Established methodological parameters were evaluated for reliability by calculating leukocyte recovery rates and erythrocyte depletion rates by both pushing and pulling methods of cell displacement. Results indicate that leukocyte sorting accumulator-3 achieves a mean leukocytes recovery fraction of 96.2 ± 2.38% by the pushing method of layer displacement. By the pulling method, the leukocyte sorting accumulator-3 yield a mean leukocytes recovery fraction of 94.4 ± 0.8%. New procedures for preliminary enrichment of leukocytes from peripheral blood that avoid cellular damage, as well as avert metabolic and phase cycle intervention, are required as the first step in many modern clinical and basic research assays.
