TOUL focused laminar flow is a system that removes 99.9% of airborne bacteria and micro-organisms, including Coronavirus Covid-19, and creates a strictly aseptic area.
Taking into account the economic burden infections have in neurosurgery, it is essential to highlight the importance of using all the tools available to reduce its impact, since even its slightest reduction can determine significant savings of resources that can be used for other prevention programs.
White AND Al.1 documented that 70% of germs in surgical wounds are carried by instruments. It is precisely the instruments that, by transporting the micro-organisms inside the wound, deeply into the organism, promote germ settlement and infection development.
The TOUL focused laminar flow device creates a strictly aseptic area in just a few seconds, and protects the operating field and the surgical instruments – which are often left open for hours in neurosurgery – against contamination.
According to strict Standard UNI 11425 2011, ISO Class 5 cleanrooms are mandatory for specialized surgeries, such as organ transplants, implants, neurosurgery and oncologic surgeries, and other complex surgeries lasting longer than 60 minutes and that require an extremely high level of protection of the high-risk area (operating table, instrument table and surgeons operating space).
With TOUL, ISO 7 cleanrooms can be turned into ISO 5 cleanrooms, in compliance with the strict Standard ISO 5, while preserving the instruments and operating field sterilization even during very long surgeries, without any time restraints.
The mobile unit is equipped with traceability for defensive medicine (label and barcode on the cover sterile housing), and does not require any engineering works to be installed.
The mobile laminar flow unit successfully reduces CFU (colony-forming units) during neurosurgery, bringing the environment to ultra-clean air levels.
Active air sampling has been performed during 45 neurosurgery procedures, 26 with conventional ventilation, and 19 with additional mobile laminar flow units (MLAF).
A total of 233 agar samples were collected.
The majority of procedures were intracranial, and included brain tumours, aneurysms, cavernomas, cranioplasty, shunt implant and deep brain stimulation.
By comparing the mobile laminar flow unit operating theatre samples with the conventional ventilation operating theatre ones, significant differences in the number of CFU were found, both near the surgical site and on the instruments table2.
