An Australian surgeon is making waves after suggesting that medical instruments could be sterilised to improve their performance and reduce infections.
Dr. Kevin Fenton, who heads the Medical Instrument and Devices Unit at the University of Melbourne, is making the suggestion in a paper for the Australasian Society of Microsurgery.
The paper, titled ‘Surgical sterilisation of medical instruments’, comes as the US Centers for Disease Control and Prevention is considering whether to ban certain types of medical equipment.
Dr Fenton is a member of the Australasia Medical Society, which describes itself as “a professional body for medical practitioners and other medical practitioners of the Commonwealth of Australia”.
It is not the first time Dr Fentons work has been linked to medical sterilisation.
In a study published in 2011, Dr Fenterons co-authored a paper that concluded that medical devices with large, thick, rigid cores could be a potential solution to sterilisation problems, particularly for the large-core device known as the Cray-20.
He says that “an alternative approach would be to treat the device with a form of biocompatible material (i.e. polyethylene glycol).
This would increase the density of the core and allow the core to be re-inflated with the injected polyethylenene glycofoam.”
Dr Fenthon is not alone in his call for sterilising medical equipment to improve performance.
Several experts have also spoken out against the use of medical devices for sterilisation, including the director of the Australian National University’s Institute of Infectious Diseases, Dr John Kost, who says that the use could have negative effects on the patient.
Dr Kost also says that a study conducted in the US found that “the incidence of HIV infection in women sterilised with medical instruments is 1.3 times higher than those who did not”.
He also says “the sterilisation is not needed to prevent infections”.
“This is a very expensive procedure, and we do not have sufficient funding to carry out this kind of study,” he told the ABC.
In the US, the Centers for Medicare and Medicaid Services (CMS) is considering how to regulate medical devices that use medical sterilisers. “
It’s a bit of a grey area.”
In the US, the Centers for Medicare and Medicaid Services (CMS) is considering how to regulate medical devices that use medical sterilisers.
The agency is currently examining the use and regulation of medical sterilising instruments, which include surgical instruments, intravenous catheters, and syringes.
It is expected to report back in February next year.
However, some experts have questioned the effectiveness of medical device sterilising, citing a recent study in the Lancet medical journal that found that the sterilising of medical machines could have a negative impact on the health of patients.
The study found that sterilising devices that have been treated with a “high-risk polymer” (for example, a polyethylenes glycol-based polymer) could lead to “unacceptable effects on patients and on the environment”.
This polymer is used in medical devices such as intravenous syringing tubes, cathears, and blood pressure monitors, and can be sterilized by heating it with a flame to achieve sterilisation at temperatures of between 1,200 and 3,000 degrees Celsius.
The polymer is highly flammable and can easily ignite if it touches the skin.
Dr Nusrat Ghafoor, professor of mechanical engineering at the National University of Singapore, told the BBC that the study “really highlights that this polymer is extremely flammant and it is very difficult to control it.”
He also said that it could cause “life-threatening burns” to the patient and “immediate death”.
“It is an important research question,” he said.
“The results suggest that we should not use medical devices when sterilising them and that they should be used for less than 10 minutes.”
The use of sterilising surgery equipment in Australia has also come under fire.
The Medical Practitioners Ethics Committee (MPEC) recently found that Australian surgeons and anaesthetists were not allowed to use surgical sterilising tools.
In 2013, MPEC said that the surgeons were not required to report to the Australian Medical Council (AMA) any problems caused by the use, and that the AMA did not enforce this requirement.
Dr Jürgen Koehler, a professor of pathology and head of the department of pathology at the Royal Melbourne Hospital, told The Australian newspaper that the committee did not have the legal authority to issue a ruling that the equipment was not a medical device and that it would not be binding on AMA.
He said the committee’s findings did not mean that surgeons could not use surgical tools, but it does mean that the medical community should be careful when using medical devices.
“I don’t think that you can say that surgical equipment is not a valid medical device,” Dr Koehl said. Dr Raffael
