If you've ever experienced a major illness or serious injury, you're probably very grateful to the medical professionals who have helped you regain your life. American researchers hope to make greater progress in improving the safety mechanisms for the storage and preparation of narcotic drugs, which is in the recent publication of Clean and Safe Anesthesia Workshop. All: The use of 3D printers to print new syringe brackets is outlined.

There may be some criteria, as well as the process of avoiding syringe contamination and drug exchange, but as the author points out, "wide variability" still exists. This is very dangerous for those who encounter medical infections, such as:

Delayed response to critical changes in patient status

Syringe exchange

Environmental pollution of syringes

Cross contamination of syringes between patients

Prototype syringe bracket with detachable support structure, printed with desktop stereolithography 3D printer

Even with new standardizations such as pre-filling syringes and automatic labeling, there are still mistakes that pose a wide range of challenges. Data show that one out of every fifteen syringes is contaminated by "potentially pathogenic bacteria".

"Increasing evidence suggests that post-operative medical-related infections are associated with such microorganisms in the anesthesia workspace, prompting the American Society of Health Epidemiology to recently publish the first infection prevention guidelines in the anesthesia workspace," the researchers said. In seeking solutions to improve patient care quality, the team considered ways to improve the following aspects:

Processing
· Availability
· Standardization of Key Drugs in Anesthesia Workshop

After studying the common causes of these accidents, the team came to a very important conclusion: not only should medical staff be given orders about their need to change their behavior, but also better tools and better organizations should be used to redesign the whole system to cope with changes in public relations.

The project is a "quality improvement program" at Massachusetts General Hospital. Researchers assess a baseline based on conventional practice, develop a better-organized device, and then evaluate supplier practices. They use 3D printing to create an organizational device to improve overall security and efficiency. So far, researchers have tested and used new 3-D printing devices in 60 operating rooms of a medical institution, and conducted post-intervention surveys and workspace audits a year later.

Series syringe bracket design based on iteration prototype and user feedback: (a) initial prototype, (b) height of main surface to provide further gap with the display of anesthesia machine, (c) alternative slot configuration with flanges to fix syringe and allow pre-loading and unloading, (d) design installed in corners, including unopened drugs The bracket of the bottle and a branch, (e) the forward part of the main surface to provide further clearance from the machine with the depth of the anesthesia monitor, (f) the final design, with a wider support clamp, to improve stability. The basic principles and practicability of these design features are examined in detail in Supplementary Table 2.

Their 3D printing syringe stent system is open source as a cognitive aid and pollution prevention method. The prototype was created on FormLabs Form 2, and in a series of customized scaffolds, these scaffolds will be connected to the anesthesia machine. The goal is to reduce transmission incidents by preventing environmental pollution and providing a way to clearly distinguish emergency medicines from medicines already used for other patients. Researchers have also developed a one-way injector system that requires only one contact and will not be put back into the stent.

The survey showed that confidence levels increased significantly when they knew there was a safer process; in fact, 76.2% of respondents reported that more than 95% of respondents had confidence in knowing where to use drugs during surveillance or handover.

One year after deployment, 94% of users reported that they found the device helpful, 96.3% said they wanted to expand the stent to non-operating room anesthesia, and 96.2% said they wanted to place the stent in other hospitals where they might work now or in the future.

Finally, the laser sintering 3D printing support and supporting trestle are selected in use. The e-stent is firmly clipped to the corner of the anesthesia machine and receives five 10-20 ml BD syringes (standard configuration includes phenylephedrine, ephedrine, ethylene glycol pyrrolidone, succinylcholine and propofol).

"One year after its implementation, employee adoption and satisfaction measurement of the device show that this intervention has led to high-value, meaningful cultural change and may result in similar improvements outside our own institutions."

Although 3D printing has had a huge impact on bioprinting and the creation of devices and implants that directly affect patients'quality of life, this technology is also responsible for various models and mechanisms that have been improved in more effective public relations, such as surgery in hospitals.
